Environmental Issues (Author’s name) (Institutional Affiliation) Issue 11 – Bio-fuels and Food Prices According to Edinburgh Napier University article on Bio-fuels, bio-fuels refers to any liquid, gas, or solid fuels products used for cooking, heating and in locomotive machinery which are derived and produced directly or indirectly from organic matter…
Taking for instance, Donald Mitchell argument on a supporting statement from World Bank report (2008). He insists that as much as several factors contributing to the increase in food prices from January 2002 to June 2008, the senior most contributing factor is attributed to large increase in bio-fuels productions from oilseeds and grains in the U.S and E.U that has increased the demand of these products while reducing supplies of wheat and crops that compete with food commodities used as bio-fuels. This has lead to land use changes in wheat and maize exporting countries shifting towards plantation of oilseeds for bio-fuel production resulting to shrunk wheat and maize production hence witnessing rise in wheat and maize prices. Donald also supports his claims from (FAPRI, 2008) that food prices have also increased due to expansion of bio-diesel production and higher costs of bio-fuel production. On the contrary, Keith sharply disagrees by arguing that the impact of bio-fuel production is much less than alarmist claim (2009). Keith K. et al rather claims that there would be greater impact if bio-fuels development focused on converting bio-waste, fast growing trees and grass into fuel. According to him, increased food prices arise out of increased demands in emerging economies, drought in food exporting countries, global warming, and market-distorting subsidies. In fact a supporting report from U.S department of agriculture (USDA) calculated that bio-fuel production only contributed to 5% of the 45% increase in global food prices. Additionally, bio-fuel crops provide alternative diversities that boost rural perennial incomes therefore reducing international burning that contributes to global warming. It hence addresses efficient production and utilization of bio-fuels, global mismanagement of land, stabilization of land cover, protection of biodiversity and improving water quality. From my point of view I would agree to the fact that bio-fuels indeed contribute to increasing food prices and other environmental drawbacks. Supporting arguments, according to Robin Maynard, when food and fuel compete for farmland, food prices will rise drastically and the poor will suffer as well as rainforests (2007). Additionally, Renton emphasizes that when forests are cleared, to create space for bio-fuel crops, they no longer serve as “carbon sinks” therefore leading to global warming as it takes longer for the benefits of bio-fuel crops to be noticeable (2007). The bio-fuel crops also displace natural ecosystems and destroy habitat for several species. Bio-fuels hence will maintain as a contributive factor to increasing food prices. Issue 12 - Nuclear Power The debate over use of nuclear power sparked out of its negative connotations in the past that threatened the survival and future of the world during the world war, nuclear disasters and links to chronic fatal diseases. Discussion have also arisen out of the proponents that nuclear power can be economical, safe and a clean form of energy. From these proponents there are disagreements amongst scholars on the question of nuclear energy. Lain Murray for instance has a positive position on use of nuclear power. He argues that the worlds experience shows it to be both safe and reliable. Supporting documents such as the Congregation Budget Office ...

But there are many negative effects of these developments which cannot be ignored. Chemical waste disposal is one such environmental issue that has led to alterations in the ecology of the world. It is an issue of environmental concern and it is a threat to the environment because every method of disposal has its own disadvantages owing to the pollution that they lead to (Bergman et al 2008).
These advancements have been very helpful but they have also been associated with many disadvantages as well. The pollution of the environment is one such problem created. Air pollution is an environmental issue of concern which is a threat to the environment owing to the ecological alterations that it leads to along with the health effects that it has for the people (Cornell University 2007).
The increase in the number of people has called for increased utilization of resources and fossil fuels for the production of energy. This is owing to the fact that the energy demand of the world has increased greatly with the industrialization and the population rise.

Dolan’s form of re-wilding, termed Pleistocene Re-wilding is unique in that it proposes re-introduction of species extirpated from their habitats thousands of years ago (Easton, 2011) Dolan’s main argument for re-wilding is the perceived benefits of reintroduction of large game to the ecosystems.
Stephen Baird and Mary Annette Rose come from opposing sides of the issue of offshore drilling. There are three main areas in their arguments: temperatures and pressures of subsea oil, effects of weather problems such as hurricanes; and leaks. Baird explained that new technologies today can guarantee and help oil companies’ efforts to prevent disasters (Easton, 2011).
DDT was used to control diseases like typhus, malaria and many other insect-borne diseases among both civilians and the military and in farms, gardens, homes etc. b) The controversy surrounding DDT was whether or not it should be banned. Anne Platt McGinn, a senior researcher at Worldwatch Institute, says ‘Yes’ to the ban, as there are ‘more effective and less environmentally harmful methods’ (Easton, 2011) Taking the opposite side with a ‘No’ to the ban is Donald R.
As a consequence, even though they may have included an environmental subject in their curriculum, it may not be extensive as it should be. Its content and way of instruction could be designed for memorization of terms alone and never paint the serious environmental degradation.
