Biodiversity
The term “biodiversity” is a combination of the words “biological” and “diversity.” It encompasses the variety of all living things on Earth. So far, scientists have discovered about 1.75 million species of plants and animals, but they estimate that the total number of species on Earth could range anywhere from 7 to 20 million. – McGraw-Hill Concise Encyclopedia of Environmental Science
 
Biodiversity is an important issue today because of the effect that human activities are having on it. For example, when we cut down trees in a forest or pollute bodies of water, we disrupt delicate ecosystems where hundreds or thousands of unique species of plants and animals exist. Such disruptions cause some species to die out while others are growing beyond their capacities. Legislation, like the U.S. Endangered Species Act of 1973 and the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), has safeguarded endangered species for years, and it is important to make sure we keep protecting new and existing endangered species as developing factors such as climate change continue to affect biodiversity.
