1. The species with the highest risk of extinction are the ones that are most closely grouped together and concentrated in one area. By protecting the local biodiversity, we can preserved the most crucially endangered animals. Once the species were same from extinction, they would begin to expand in numbers, and therefore create a larger global population.
2. A loss of species diversity in one area can definitely impact the globe, especially in the economy. Today's interwoven financial system throughout the planet has created essentially one enormous market. If the fishing industry in the Gulf Coast, for example, were to go under, then any areas that ate fish taken from the endangered ocean space would have a shortage. This might lead them to find substitutes for the Gulf fish. These substitute fishing markets, from being overworked, could then have fish shortages of their own. In this way, a local crisis can become global issues.
3. Evidence shows that by preserving the local ecosystems has a positive impact for the human population. In one example, an excessive season of whale hunting caused a string of events that led to the decimation of the local fishing industry. By preventing these destructions of the food chain, we can sustain our livelihoods as well as the environment.
