Ecosystems

Paper Summary:

This paper examines the world's ecological systems. It begins by defining ecosystems and describing what makes them up. It then describes the formation of different ecosystems. The paper then looks at what is being done to protect and promote the ecological systems in the world and if these measures are effective.

From the Paper:

"The Endangered Species Act of 1973, often referred to as 'nature's safety net,' was passed to protect and recover imperiled species and the ecosystems upon which they depend (Endangered). In other words, when management practices and other conservation laws fail to maintain healthy animal and plant populations, the ESA acts as a last barrier to a species' extinction (Endangered). When a species becomes listed on the ESA list, it stands a good chance of survival, yet then the more difficult, time consuming, and expensive task of reversing the decline, restoring the species to a secure status, and removing it from the list begins (Endangered)."
