Biology paper essays
Biology paper essays In the article, Condition Critical: An exclusive look at a U.N. assessment of Earths ecosystems shows they are strained to the limit, the author Eugene Linden begins by addressing the fact that the Earth has been showing signs of distress for the past forty years. The signs were not as noticeable at first, but as time drew on, the fact that Earth was in trouble became very clear. Linden believes that the few who take an active role in preserving the Earth and the minor programs that have been started are just not enough to stop the downfall of Earths ecosystems. At the United Nations millennial session they started a four million dollar project called the Pilot Analysis of Global Ecosystems (PAGE). This study will determine whether or not Earth is in the downward spiral that many scientists believe it is. This study will set the stage for a much larger twenty million dollar study called the Millenium Ecosystem Assessment, which is set to begin next year. PAGE is sponsored by the U.N. Development program and the World Bank which are agencies that deal primarily with economic issues. However, their involvement in PAGE turns towards the likely possibility that if the environment of Earth is unhealthy, then economies will not prosper either. Page also points out that the worlds population is producing beyond its capacity. The Earths fishing fleets are 40% larger than the oceans can support which will eventually put a good number of fisheries out of business. In the past thirty years, global economies have increased food output and livestock production but have depleted and polluted water supplies, ruined the soil and destroyed habitats. PAGE also examines how human and industrial interference can disrupt the Earths ecosystems. PAGE reveals how the excess release of carbon dioxides and nitrogen into the atmosphere can have negative eff...
