Diffusion and network effects Essay Example | Topics and Well Written Essays - 2000 words

Diffusion and network effects - Essay Example It starts with Innovators, who are the educated, risk oriented, information seeking people and who like to try new experiences. These roughly comprise of 5% of the population (Davidoff and Kleiner, 1991; Dewett, Whittier and Williams,, 2007). Next, are the early adopters, who are educated young and popular people and may be opinion leaders in their groups (David, 1985). Next are the early majority who are cautious and wait out to see how new products are reviewed by the early adopters. The early majority consist of a large number of people and these are also instrumental in propelling the late majority (who are older, conservative and low on social activity) into adopting the technology. The Laggards are the remaining people who missed out on adoption and may adopt the product toward the maturity of the product (Farrell and Saloner, 1985). Figure 1: Diffusion of Innovation Curve (Source: Rogers, 2003) In the case of Facebook, the adoption process started with ‘‘Innovators ’, but these e Innovators were the people who already had adopted older social networking versions like MySpace and Orkut. With the creation of Facebook, these ‘Innovators’ simply converted to Facebook and encouraged the early adopters to choose Facebook when they were ready to embrace the online social-networking concept (Fernandes, 2011). However, the diffusion of Facebook during the initial phases was also constrained by the diffusion of the Internet. Innovators and early adopters were therefore largely confined to the USA, Western Europe, Australia, and parts of India and China. As the Internet penetration increased with the development of broadband technology and liberalisation in other parts of the world, it spread to Middle East and then to the Latin America, Africa and Eastern Europe and Russia (Fowler, 2012). So, while regions like the Middle East, Brazil, South Africa and Russia were now in the ‘Innovators’ and ‘Early Adopters’ phases, at the same time, the USA had and Western Europe had moved on to ‘Late Majority’ and the ‘Laggards’ phase as shown in the following figure. Figure 2: Stage of Adoption (Facebook) Source: CheckFacebook.com, 2010 3. Five Factors that Determine Success or Failure of Adoption Adoption, which is an individual process that depends on several attributes of the innovation like the relative advantage, compatibility, complexity, trialability and observability. Figure 3: Factors Determining Success of Adoption (Facebook) Relative Advantage Relative advantage, as the phrase suggests, is the perceived value added or additional advantage that a person thinks he can derive from adopting the new product (Haggman, 2009). In the context of Facebook, it offered the relative advantage over sites like MySpace and Orkut because of its higher level of security, the ability to limit who views the profile and ease in uploading and managing photographs. The user interface o f Facebook is also much more user friendly. Also, the spam prevention mechanism on Facebook is much stronger when compared to other social networking sites such as Orkut. So, users perceive it to be a more secure and private option than the existing ones. Compatibility Compatibility is the level of ‘

DELACROIX Essay Example | Topics and Well Written Essays - 750 words

DELACROIX - Essay Example In London, Delacroix studied various works of English painters who he greatly admired and inspired some of his later works (Villarreal par. 25). The trip to London brought Delacroix closer to mimicking the works and colorful style of Reuben’s paintings. Such influence of English paintings and artwork was evident in his later work in 1930, July 28: Liberty Leading the People. The painting Liberty Leading the people commemorated the recent French revolution as this canvas was a reflection of the artist’s change of style. Delacroix fascination for the work of English painters started early in his career pushing him to visit London. Various elements of artistic migration are evident in Eugene Delacroixs works especially after a visit to England. Most of Delacroixs works between 1820 and 1830 were greatly influenced by the English painting particularly after visiting London in 1825. Delacroix visited England accompanied by his artistic English friends Thales Fielding and Richard Parkes. Even early before 1830 and before the visit to England, Delacroix had great interest in English paintings especially the use of watercolors and oil techniques evident in English landscape paintings. The artist’s friendship with English friends greatly influenced the love and interest in English works. Delacroix’s works when during the time he was in England show great influence from the English painter, Sir Thomas Lawrence. Most of the artist’s works depend on his interpretation of the British portraits according to his understanding and personality. One of Delacroix’s most outstanding works during the period he was in London was the portrait of Louis-Auguste (Baron) Schwiter in 1826. The painting is similar to most English portraits from the time by trying to capture schwiters character as he is posing and standing in a park. Delacroix does not portray a relaxed attitude of Schwiter but chooses to emphasize on

Physiology Essay Example | Topics and Well Written Essays - 3500 words

Physiology - Essay Example This pathway consists of A & A fibers characterised with high velocity (30 to 110 m/sec) of impulse conduction. The dorsal column-lemniscal pathway has also high degree of spatial orientation of the nerve fibres; particularly the medial fibers convey the information from the lower parts of the body while the lateral fibers related to higher segments. The spasticity in the muscles is related to the pyramidal insufficiency. This condition can occur if pyramidal pathways controlling voluntary movements are damaged by the mechanic or other agents. Intoxications, chronic neurodegenerative diseases, traumas, and metabolic disorders can play role in the origin of muscular spasticity. The attenuation reflex is important protective mechanism providing the best sound perception. The contraction of the stapes muscle protects the inner ear from damaging. The role of outer ear structures is important also - they can reduce resonance in the middle ear. Summation is a process of gradual release of the transmitter and the transmission of the impulse from several presynaptic neurones to one postsynaptic neurone (spatial summation) or from only one presynaptic and one postsynaptic neurone (temporal summation). The summation leads to the release of sufficient the impulse is transmitted across the synaptic cleft. The pain control system of CNS is represented by three major components: the periaqueductal grey and the nucleus raphe magnus (in the brain) and the pain inhibitory neurons of the dorsal horns in medulla spinalis. The opioid receptors of these structures are activated by endorphins or exogenous opiates and block the spreading of pain impulses. 3.3 Why is it difficult to localize slow, chronic pain (2) Chronic pain usually irradiate to other areas thus its localisation could be difficult. Furthermore, the efferent pain stimuli are conducted to CNS

Critically discuss why technology is important within the operations Essay

Critically discuss why technology is important within the operations domain but that its implementation is problematic - Essay Example In this manner the application of CIM makes strategic management more effective. Therefore its importance in the operations domain cannot be questioned. However the expectations from technology are not always realized because of the lack of end-user involvement which makes implementation problematic. If the end-users are not involved in the implementation cycle, then the finished software may not address all the operational processes as required. Since the end-users are directly responsible for the operational processes, they should be involved in the implementation cycle in order to ensure that the technology is integrated into the operations environment in the right way. However facilitating end-user involvement may not always be possible. An important element of the implementation cycle is project management. A project management team consisting of qualified personnel must be formed in order to ensure that the implementation is strategically aligned. However the formation of the p roject management team is separate from the day-to-day operations of the organization. Therefore the management may not be in a position to provide the required personnel when it comes to managing the project of technology implementation.

The effect of vitamin D on Multiple Sclerosis Research Paper

The effect of vitamin D on Multiple Sclerosis - Research Paper Example Vitamin D is vital in improving several symptoms associated with MS. However, it is unclear as to whether consuming supplements having vitamin D can prevent one from developing multiple sclerosis or treat the symptoms after the illness affects a person. Certain genes also link with the development of MS. However, since researchers portray differences with regard to their understanding pertaining to multiple sclerosis, it is difficult to know if vitamin D can help is treating or preventing different instances of MS (Robinson, 2015). For example, in case an individual develops multiple sclerosis and want to consume vitamin D, it may not harm cause harm or worsen the symptoms. Nonetheless, people may be unlikely to witness any changes to the symptoms they develop. They should refrain from taking vitamin D in line with other types of medications. Therefore, an individual should consult a doctor before consuming supplements, such as those having vitamin D (Watson, 2013). Vitamin D may prevent a person from developing MS or minimize its severity. It plays a crucial role with respect to helping an individual develop healthy bones. Nevertheless, researchers are looking for certain ways in which they can reveal the role that vitamin D plays in diverse body parts. However, although vitamin D may boost the nervous and immune systems in an individual’s body, the manner in which it works it unclear (Swanson, 2015). Certain cells in the nervous and immune systems of a person have vitamin D receptors. The receptors prevail on a cell’s surface whose role is to receive signals from chemicals. Once the cells merge with receptors, chemical signals direct cells to behave in certain ways, die or divide. The cells also regulate the amount of vitamin D present in them. For instance, after the immune systems of a body are subjected to vitamin D using laboratory experiments, they tend to swell. This reveals that

International Operations Management Essay Example for Free

International Operations Management Essay Nowadays every company wants to gain a competitive edge in the market and for that it leaves no store unturned . When any new development takes place although it has a good side to it but there are equally a lot of challenges attached to it as well. If a company is thinking of moving from batch processing to line processing there would be considerable concerns which the following departments might raise and might have to juggle with. The finance department might face the issues of capital investment rising from moderate to high level because if an automobile production line is there then it would not use ordinary machinery instead would require specialized machinery for its production. In a batch processing system the capital investment is usually seen to be moderate and when decision of venturing into line processing is taken then capital investments expects to be high. Variable cost might tend to lessen from moderate level of previous working seen in batch processing. Human resource department would also have to face issues like curtailing the number of labor content and workforce . Usually in assembly line processing the workforce is replaced by machinery and supporting mechanisms embedded in the systems like for example adding a conveyer belt to connect the activities which take place in the firm. (Lewis Slack, 2003). Labor content in batch processing is moderate whereas in line processing its low. (McHugh MuHugh , 1990) . This can be a concern of the human resource department because it would take decisions like lay off, transfer etc. The accounting department has to be on the toes because the level of transactions would increase as the volume would increase i. e. from moderate level of quantity produced to high level production. The entries have to be made on a continuous basis as volume or the quantity has risen. The information system which would be used for line processing will have to more swift and embedded with specialized softwares or systems which support line processing nature of work. The connected flow of working will have to be monitored efficiently. The system of monitoring will have to be modified so as to facilitate the current functioning. The marketing department might think of the fact that in the batch processing products involved were several and in line processing the products involved are less hence less responsibility, but the quality of marketing expertise would be expected to increase drastically. ( Heizer Render , 1991 ) . A batch process usually executes different production runs for different runs but it’s not in the case of line processing. The flexibility is usually seen to be low in line processing and therefore as in batch processing where flexibility is seen to be moderate might create concerns for the marketing department. The marketing department now will have to devise such ideas which are out of the box and facilitate such larger processing function . The marketing department has to design such products which entice the masses as they would now not have multiple products which can save their flagging reputation. (Weiss Gershon, 1989) To culminate I would state that whenever any other process flow is adopted then there are certain specifications which are to be considered and the various departments which previously followed a specific line of action need to have the insight of how to adapt to the other one in which they are opting to venture.

Climate Change And Renewable Energy Options

Climate Change And Renewable Energy Options Climate change is the consequence of any kind of adjustments in the climate system. Change in climate is caused by fluctuations in the factors that influence climatic patterns. This phenomenon has become one of the greatest environmental threats and risks that the world is facing. Persistent human activities such as driving cars, farming, deforestation, and industrialization result into production of greenhouse gases. These gases gather in the atmospheric space, and trap the heat from the sun. This is what causes climate change manifested through global warming and other processes. The effects of disruptive changes have led to catastrophic events like storms, droughts, rise in the sea levels, and floods (Kammen Casillas 2010, p. 1181). Climate change is majorly caused by greenhouse gas emissions. Most of the intervention efforts meant to mitigate the impacts of climate change thus target human activities that contribute to additional emission of greenhouse gases into the atmosphere (Letcher ScienceDirect 2009, p. 67). Therefore, renewable energy has been considered as one of the leading solutions to climate change. Provision of carbon-neutral sources of power, heat, transport fuels and renewable energy options has been considered by environmental scientists as a great move in the right direction. The objective is to enact a transition from high to low carbon economy. Although the renewable energy sector is quickly changing, climate change crises dictate that the energy system be drastically transformed. This will help in combating the dangers that are associated with global warming that threatens to slump the global economy in the face of globalization and industrialization. Roggema (2009, p. 211) cited air pollution caused by transport and power sectors of the economy have been a great threat not only to the human health but have also shifted the climate systems. Prospective Interventions to Address Climate Change Crisis Climate change as an environmental problem is essentially a problem caused by the extreme utilization of fossil energy. Agriculture, changes in land use, cement production and use of chemicals all contribute to the emission of the greenhouse gases (Roggema 2009, p. 234). However, 70% of the global warming/climate change problems is caused by unsustainable use of fossil fuels. Therefore, in order to deal with the problems related to climate change, there has to be a shift from use of fossil fuels at home, in the industries, transport and generally the entire sectors of the economy (Roggema 2009, p. 203). In order to avert the challenges associated with climate change, saving of energy is essential. Electricity, automobiles and carbon emissions are the main causes of problems related to climate change. The regular incandescent light bulbs should thus be changed and replaced with the energy saving compact fluorescent bulbs which are more efficient and energy saving. The emissions that result from automobiles like motor vehicles, motorcycles should also be reduced (Letcher ScienceDirect 2009, p. 154). Climate change has been caused by human activities such as deforestation in search of more space for agricultural activities. Therefore carbon dioxide concentration in the atmosphere continues to rise. Being a greenhouse gas, carbon dioxide has contributed to the rise of global temperatures. Roggema (2009, p. 183) cited that human activities that encroach to the environment should thus be limited to prevent further crises associated with global warming. Traditional methods of conservation of forest ecosystems should be embraced to preserve the ecosystem and mitigate the effects of climate change (Tracy 2010, p.353). Therefore reforestation should be encouraged so that the greenhouse gases like carbon dioxide are reduced from the atmosphere. Farming activities that promote environmental hazards such as soil erosion should thus be limited and replaced with farming approaches that are environmentally custodial. Industrialization is the major contributor to climate change. This is because of the emission of the greenhouse gases like Nitrous Oxide and Carbon dioxide (Tracy 2010, p. 354). In order to avert climate change challenges there should be focus on change in the energy used in the industries from the dirty to clean energy. Climate change scientists have advocated for the use of renewable energy as the solution to the climate change problems that are caused by the use of environmentally hazardous fuels like coal and nuclear energy in the industries in the global economy (Tracy 2010, p. 355). Climate Change and the options for Renewable Energy Human activities and natural environmental processes are all responsible for climate change. Natural causes include volcanic eruptions, ocean currents, changes in the earths orbit and solar variations. An eruption of volcanoes throws out great volumes of sulphur dioxide, water vapor, dust, and ash into the atmosphere (Wengenmayr 2008, p. 141). The large volumes of gases and ash have the ability to influence climatic patterns by increasing the planetary reflectivity leading to atmospheric cooling. The aerosols are produced by volcanoes also affects the purity of air in the atmosphere. These contribute greatly to climate change. The oceans currents are considered a great threat to the climate stability. The currents release great amounts of heat across the planet. Besides, the interaction between the ocean and the atmosphere can produce El Nino. The oceans determine the atmospheric concentration of carbon dioxide. This implies that changes in the ocean circulation greatly affects climate and significantly contributes to the climate (Wengenmayr 2008, p. 231). Climate change has been caused by human activities. MacZulak (2010, p. 9) cited that this is majorly through the burning of fossil fuels, changes in the land use, and industrialization. With industrial revolution of the 19th century, fossil fuels have been used to support industrial processes. Fossil fuels such as oil, coal and natural gas have been great energy supplies for the industrialized economies. However, these sources of energy have contributed to great emissions of the greenhouse gases in the atmosphere. These are responsible for climate change (MacZulak 2010, p. 8). Carbon dioxide concentration in the atmosphere has increased because of human activities such as deforestation and agriculture. Methane is released through oil drilling, mining of coal, leaking gas pipelines, landfills and waste dumps (MacZulak 2010, p. 9). These greenhouse gases cause great increase in the climate change and are significantly responsible for global warming. The greatest cause of climate change and global warming however is the burning of the fossil fuels. These fuels cause emission of greenhouse gases into the earths atmosphere leading to depletion of the ozone layer and global warming (Twidell Weir 2006, p. 143). Options for Renewable Energy The term renewable energy is used in reference to the energy resources that occur naturally in the environment and can always be re-used after the initial function. Examples of this energy are the solar, wind, hydro, and geothermal energy. Rivers, biomass and garbage are also considered as renewable energies (Abid, Crawford Davoudi 2009, p.167). Renewable energy is the future of the earths energy needs. However, in order to effectively combat climate change-related challenges, the global mean temperatures have to be kept below two degrees Celsius. This calls for prior planning and transformation of the industrial sectors use of energy. Renewable energy has the potential decreasing the use of fossil fuels that are to blame for most of the problems associated with climate change (Abid et al 2009, p. 169). Renewable energy sources such as wind energy, solar energy, and the bio-fuels are increasingly being used as energy alternatives. With the climate change and its crises, such form of energy has the advantage of energy security since the fossil fuels will be depleted as a result of climate change. Climate change is largely a consequence of anthropogenic activities such as burning of the fossil fuels, industrial processes, deforestation and the release of greenhouse gases into the atmosphere. It is estimated that the power sector by itself contributes about 40% of the total carbon emissions (Abid et al 2009, p. 297). This can only be altered by shifting to the use of renewable energy. Climatic impacts such as tsunamis, droughts, wildfires, floods, storms, heat waves and tornados are consequences of climate change (MacZulak 2010, p. 8). However, according to the climate change specialists, clean air policy that includes use of renewable energy can substantially mitigate the negative impacts of climate change caused by fossil fuels. Renewable energy technologies are considered to be the most potential mitigation for greenhouse gases. In the steadily growing awareness on the importance of environmental protection priorities, renewable energy is considered appropriate in the mitigation of climate change effects (Chiras 2007, p. 67). Renewable energy is the alternative to the climate change crises since it does not produce greenhouse gas emissions and pollute the air as is the case with the fossil fuels. Chiras (2007, p. 17) indicated that biomass energy for example, has been used as an alternative for fossil fuels so as to conserve the environment. It is considered a greenhouse gas neutral since its combustion releases no more carbon dioxide than was absorbed during growth period of the organic material. Biomass fuel also contain little sulphur and low combustion temperatures. This limits the formation of nitrogen oxide which is a greenhouse gas dangerous to the environment (Abid et al 2009, p. 269). Responding to Climate Change The transport industry is driven mostly by petrol. This causes emission of carbon dioxide into the atmosphere. The carbon dioxide combines with other greenhouse gases in the atmosphere and cause global warming. In order to deal with this menace, there is need for countries to invest in energy efficient technologies like plug-in hybrid electric vehicles and new technologies such as hydrogen cars (Abid et al 2009, p. 297). This has the potential of reducing petroleum emissions of greenhouse gases into the air. Further, there is need to shift from air and truck transports to electric rail transport that reduces emissions significantly. Industries should shift from the fossil fuels to use of bio-fuels such as ethanol and biodiesel fuels should be used in the gasoline engines in the industrial economies. Abid et al (2009, p. 169) cited that electric vehicles can contribute into reduction of dangerous gases into the atmosphere especially if the energy is produced through the renewable energy sources. In order to deal with climate change and environmental crises associated with it, elimination of waste methane is required. Methane is considered to be one of the strongest greenhouse gases that are responsible for the climate change problems. Waste methane should thus be dealt with responsibly. This is through careful handling of oil wells, landfills, coal mines and the waste treatment plants (Chiras 2007, p. 17). This will provide a net greenhouse gas emission benefits. Biomass as a source of bio-energy can be used to capture carbon. Biomass traps carbon dioxide in the atmosphere through photosynthesis. When biomass is decomposed through combustion, carbon is released as carbon dioxide. This is the process involved in the carbon cycle. Biomass fuelled power plants result into a net-negative carbon dioxide emission. This implies that there will be less carbon in the atmosphere will be trapped through the technology and reduce greenhouse gases that are a threat to the environment (Abid et al 2009, p. 169). The adoption of renewable energy technologies is strategic in addressing the problems associated with climate change and global warming (Ehrfeld 2009, p. 113). From 1970s and 80s, development agencies have promoted small-scale renewable energy technologies. This includes the use of biogas, cooking stoves, the wind turbines and solar heaters in the industrializing countries. In the large scale developing countries have responded to climate change through the use of ethanol in the transport sector. This is especially the case in Brazil. In India, biogas is being used in households for lighting and cooking. Grid connected power in India and hydropower are being used in India and Nepal respectively as renewable sources of energy and safe energy for environmental conservation (Ehrfeld 2009, p. 119). Naturally Sustainable Renewable Energy As oil reservoirs and oil wells in the world run dry due to extensive exploitation and use in the energy sector, there is also an outcry in the environment that is caused by their consequences. Renewable energy sources include geothermal energy, solar, hydroelectric, biomass and wind energy (Chiras 2007, p. 233). These forms of energy have been considered to be the most environmental friendly because they dont produce high levels of greenhouse gases and other substances that are not environmentally friendly. The challenge that these forms of renewable energy have is sustainable use. Hydroelectric power uses the movement of falling water to run the turbines. Unlike other sources of energy, hydroelectricity does not depend on the fuels like natural gas or petrol to run the engines. This makes it more environmentally friendly. Besides, it is more sustainable with the sustainability of the environment so that water capacity of the dams is not interfered with. It uses the natural progression nature to generate electricity (Chiras 2007, p. 117). Hydroelectric power does not produce direct waste that pollutes the environment. It is thus considered to be environmentally sustainable (Ehrfeld 2009, p. 114). The carbon dioxide levels produced by hydroelectric power plants are considerably very low. This is however only produced during the construction stage of the plants and not in the operational phase of the plants making it environmentally friendly. As a renewable source of energy, hydroelectric power does not need the use of fuels to run the turbines. The use of petrol in the production of hydroelectric energy is not existent. This implies that when the price of the fossil fuels rises, the hydroelectric plants are often not affected. This makes it a sustainable and reliable source of energy when compared to other sources of energy (Ehrfeld 2009, p. 116). It also means that the consumer price of this form of renewable energy is fairly constant. In terms of sustainability, hydroelectric power stations last longer than the energy plant stations that are powered by fossil fuels. They are generally easy to maintain and pose no much threat to human life and property. Hydroelectric energy plants contribute to conservation of the environment. In the countries where great investments have been done in the hydropower such as Bhutan, environmental stewardship and custodianship is encouraged. Ehrfeld (2009, p. 119) cited that since it depends on water, a lot of forest conservation and reforestation is encouraged. This helps in the reduction of the carbon dioxide concentration in the atmosphere. The human activities that contribute environmental degradation are also reduced through investment in the hydroelectric power plants. Climate change is caused by human activities that tamper with the environment. However, when a country invests in the hydroelectric plants, environmental conservations efforts are boosted. With the conservation of the water catchment areas and the forests, hydroelectricity becomes a very sustainable and reliable source of renewable energy. As it produces clean energy through environmentally friendly approaches, it also helps in the protection of Mother Nature (Ehrfeld 2009, p.121). International Agreements and Government Interventions in Climate Change Various intervention efforts have been made at the community and individual levels to combat climate change and to reduce the negative effects of human activities on the environment. However, much is still needed to be done especially at the inter-state and governmental level. One of the efforts that the governments from the industrialized countries are making in the mitigating climate change is through the Kyoto Protocol. The focus of the protocol is in the reduction of greenhouse gas emissions especially from the industrialized countries by 2012. The developed countries have the responsibility to reduce their emission of greenhouse gases from their large industries. These gases contribute to global warming and climate change. The Kyoto Protocol intervention targets reduction of carbon in the atmosphere (Karlsson, Lund, Mathiesen 2010, p. 488). This is through emission trading, clean development mechanism and the joint implementation. These strategies target reductions of greenhouse gases in the atmosphere. The countries that are signatories are thus investing in renewable energy technology options in the industries. The UK government considers climate change as a priority. Its approaches include targeting households to help in energy saving and strengthen renewable energy adoption. Civil society, community and private organizations are also strengthened through grants to help in generation of renewable heat from the renewable sources (Ehrfeld 2009, p. 115). The industrialized countries are re-focusing investments towards generation of renewable energies that are environmentally friendly and are sustainable. There is thus need to encourage less use of fossil fuels and more investment in the bio-fuels. Improvement of energy efficiency is a good government strategy for dealing with the climate change problems. Reduced use of energy implies reduced production of carbon dioxide. Karlsson et al (2010 p. 501) cited that this calls for more efficient vehicles, motors, appliances and industrial processes. Besides, development of renewable energy sources such as solar, geothermal, hydroelectricity, and biomass should be encouraged to reduce the consequences of greenhouse gases in the atmosphere. The transport sector should reduce gasoline consumption. The trucks, cars and buses use almost half of the oil in the United States. There is therefore urgent need for investment in electric and fuel-celled vehicles so as to reduce the emission of carbon dioxide. Transport policies should also encourage less driving of single-passenger vehicles in order to reduce greenhouse emissions (Ehrfeld 2009, p. 115). Human activities that involve land use are largely to blame for destruction of the environment. Governments should focus on developing agricultural policies that discourage environmentally hazardous practices and activities such deforestation and other human activities that are dangerous to the environment. Climate change has negatively impacted on food security. In order to therefore fight poverty, climate change must be addressed through agricultural activities and policies that are environmentally friendly (Kammen Casillas 2010, p. 1181-1182). Conclusion Climate change is greatly caused by human activities more than the natural processes. Industrialization and agricultural activities are largely responsible for the production of greenhouse gases that promote global warming and other consequences. These threaten wildlife and human existence and as such should be addressed. Renewable energy is the potential rescue of the environment from the negative effects of human activities. Governments and countries thus need to use less of fossil fuels and invest more in renewable energy technology options. These include hydropower, geothermal, wind energy and other reliable sources of environmentally friendly renewable energy sources.
