Habitat Destruction :: essays research papers
Habitat Destruction Overview à à à à à 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 speciesââ¬â¢ homes or habitat destruction. Habitat destruction or habitat loss is the altering or elimination of the conditions that plants and animals need to survive. ââ¬Å"The primary threat to the worldââ¬â¢s biodiversity is habitat destructionâ⬠(Okey p.1). Prairies have been greatly affected. The ââ¬Å"loss of prairie habitat ranges from 20 to >99 percent depending on the regionâ⬠(Benedict, Freeman, & Genoways, p.161). Habitat destruction can be caused by many things. These include: The introduction of alien (exotic) and domesticated species Pest and Predator control The collection of animals for pets and research Pollution Ecological factors Loss of keystone species Overexploitation Disease Limited distribution Many of these causes could be prevented fairly easily. If people today would just follow some simple rules, none of these would be as big as they are now. The Introduction of Alien (Exotic) and Domesticated Species à à à à à Introducing exotic species has been a highly debated issue. Why should we bring another animal or plant into a region to eradicate another species? Thatââ¬â¢s the question that people have been asking for ages. Of course, there are positives to bringing in another species, but many times, there are just as many negatives. Also, these species can be introduced accidentally or intentionally. The new organism may cause no obvious problems and eventually, it will be considered ââ¬Å"nativeâ⬠to the area. For example, corals are ââ¬Å"perhaps the oldest animals on the planet, and these long-lived corals have evolved in one of the Earthââ¬â¢s most stable environmentsâ⬠(Eichenberg, p.2). If a new type of fish were to be put into the ecosystem with the corals, the coral would be affected. First, the fish might eat the coral. Second, they could use the coral for shelter, and possibly damaging it that way. Third, the fish could bring predators that might also eat the coral. Introducing an exotic species has the ââ¬Å"rippling affectâ⬠of dropping a stone into a pool of water. Everything outside the epicenter is affected. A study was done at Cornell University, and they estimated that $120 billion per year are spent fixing the problems caused by exotic speciesâ⬠(Chiras, p.
