Oceania - Overfishing

Overfishing - the taking of excess fish from the wild which prevents food for other species and limits the number of future fish. This is another serious issue in Oceania. Fish are taken not only for food but also hold a great demand for the pet industry. Coral reefs are destroyed and fragments are taken to other locations and sold for profit. This issue is being address and there are many ways to overcome it.

Oceania - Pollution

Chemicals such as pesticides are used in Oceania for protection of crops etc. This contributes to both air and water pollution. Water pollution is a serious thing in Oceania because it has a drastic impact on marine life. Air pollution is also caused by vehicles and the dirty industry businesses.

Oceania - Deforestation

Deforestation - the clearing and destruction of forests to harvest wood for consumption, clear land for agricultural uses, and make way for expanding settlement frontiers. Throughout Oceania rainforest are being clear cut to make room for the growing cattle and crop industry.

Oceania - Introduction

Oceania consists mainly of Australia, New Zealand and Papua New Guinea with the addition of other island chains. There are a variety of landscapes throughout this continent. From the lush rainforests to open savannas people from around the world travel here. There are urban cities and remote locations.

There are many endangered animals found in Oceania here are a few listed below:

North America - Overfishing

Overfishing - the taking of excess fish from the wild which prevents food for other species and limits the number of future fish. When settlers came over from Europe many years ago this land was described as "there as so many fish their you can walk on the water." Now that saying can no longer be said due to the aggressive fish market. Governments now put out laws to protect the remaining fish and fish are now raised in semi-captivity for human consumption by the aquaculture process.

North America - Deforestation

Deforestation - the clearing and destruction of forests to harvest wood for consumption, clear land for agricultural uses, and make way for expanding settlement frontiers. Throughout North America forests are clear cut for use of raising cattle and growing crops. However laws are in place to protect the last remaining forests in Canada and the United States of America.

North America - Pollution

North America is very populated and with the endless number of people comes pollution. Chemicals such as pesticides are used by farmers to stop insects from killing crops but intern kills of other animals such as birds. DDT was a big problem in North America when used as a pesticide. Farmers sprayed in on crops the insects lived either on or near the crops, then smaller animals ate the insects, such as a mouse. Then a snake could eat the mouse and then a hawk could eat the snake. The DDT gets built up in every food chain level and since it can not be decomposed when the hawk dies the DDT goes back into the environment. The chemicals contribute to air and water pollution as well as too many vehicles on the road, industrial plants and other areas that use fossil fuels to run.

North America - Introduction

North America, consisting or Canada, the United States of America, Mexico and a few Central American Countries is one of the most visited places on the planet. There is everything from the temperament forests in Central America to the Rocky Mountains to the East Coast Fisheries. There are large urban cities where life never stops to small towns. However with the over population of some areas in North America comes with a list of problems.

There are many endangered animals inhabiting North America, some which have the possibility to be saved. Other animals have numbers which are far to low and they may disappear forever.
