In the past, species of plants or animals used to die out or become extinct naturally because more recently evolved species were more successful at competing for food and living space. Some became extinct because of changes in the planet or because of natural disasters. Today, however, most plants and animals become endangered because of the interference of humans.
The introduction of exotic, non-native species has negatively impacted many animals. These non-native species disrupt natural systems, compete for food, space, and other resources, and may introduce disease. Over-hunting and over-harvesting has had serious effects, but habitat modification or destruction has been the most devastating to the earth's animals.
Sample some of the following activities to learn more about endangered animals.
The following are places to go (some real and some virtual) to find out about endangered animals.
Asian elephants are endangered in the wild, where perhaps only 30,000 still live in forests of south and southeast Asia. They are endangered in North American zoos, too.
