Habitat Destruction

Overview

In this new age of technology and advances in every possible field of study, many people forget about the environment. Some will just throw their trash all over the place with no concern for the possible consequences. Of course, there are many consequences, but only one comes to my mind. That is the demolition of species' homes or habitat destruction. Habitat destruction or habitat loss is the altering or elimination of the conditions that plants and animals need to survive. "The primary threat to the world's biodiversity is habitat destruction" (Okey p.1). Prairies have been greatly affected. The "loss of prairie habitat ranges from 20 to >99 percent depending on the region" (Benedict, Freeman, & Genoways,

This in turn, has led to the steady decline of the quality of the fishing.

The Collection of Animals for Pets and Research This is not something that most people would think about, but it has a big impact. The number of animals imported into the U.S. is amazingly high. In 1997, 85 million fish, 920000 live reptiles, 728000 reptile skins, and 11000 live birds were brought into the United States. There is one other fact that is very high. "For each bird that makes it into someone's home, though, 10 to 50 may die along the way" (Chiras, p.220). Also, scientists collect monkeys and chimpanzees for research on medical problems like AIDS. When they take these animals out of the food chain and ecosystem, it creates a "hole" where they used to live and feed. This will mess up the entire food chain.

Pollution Some examples of pollution that affect habitat are global warming, acid deposition, and ozone depletion. Global warming has contributed to the coral reefs dying out. There is so much pollution in the world today, that several species have become extinct. It's sad that their extinction could have been prevented so easily, and yet we did nothing about it. In prairies or grasslands, the plants use nitrogen. A study done on the nitrogen uptake by ryegrass found out that "the mat of roller-chopped material certainly influences regrowth and consequently atmospheric fixation by legumes. Moreover, the nitrogen contained in
