population has climbed‚ the extinction rate of other species has also gone up; indeed‚ humans began causing extinctions about 45‚000 years ago (Conservation of wildlife populations 2007‚ L.Scott Mills). The Dodo bird Raphus cucullatus is an extinct flightless bird which once occupied the island of Mauritius (Figure 1) Sailors hunted the bird to extinction and the bird is now recalled as stupid and dumb for not getting out of the way of humans causing their extinction.

Forests are the lungs of the earth and they should not be destroyed. Deforestation causes not only the loss of our precious and stunning forests‚ but also habitat destruction‚ extinction of species‚ and the loss of necessary resources. It’s imperative to prevent the total destruction of our land so that we might be able to salvage what’s left of our environment. If we don’t stop this problem soon there will be no future for our children. Habitat destruction is the awful process in which natural

Extinction is a natural selection process. Should humans strive to preserve a representative sample of all biomes or aquatic zones? Why should humans be concerned with the extinction rate? In my own opinion No but as u read more about it some things need to be preserved. For instance animals help the crops of the foods that we eat. Snakes help to cure different diseases. Humans help the plants and animals to grow. The fact that human beings are a species means that they depend on many other species

Although humans seem to interfere and even initiate this decline of animal population‚ we ourselves are a product of nature‚ and if allowing extinction benefits the overall wellbeing of our species‚ then it is our natural obligation to allow such extinction to take place.

In this essay‚ I will be discussing the leading causes of the recent endangerment of both the North American bats and coral reefs. There are ultimate and proximate causes for each of these species continued extinction. In correlation‚ the extinctions of North American bats and coral reefs would severely impact other organisms in their ecosystem in any ways. Most recently biologists went to complete their annual bat census only to discover that an abundance of bats were quickly dying off or already
