Endangered Species

What is an endangered species? It is a group of individual organisms, known as a species, that are at risk of becoming extinct or are threatened by changing habitat parameters. Organisms include vertebrates, invertebrates, and plants. Impact to the species can come through environmental or human influence. Almost 100 species become extinct every day according to the United Nations. The World Conservation Union estimates that 40 percent of all organisms are “endangered”. Research estimates that extinction rates over the last 150 years exceed the average background rate of the planet by 100 to 1000 times.

Legislation passed in 1973, called the Endangered Species Act, was designed to protect species of plants and animals from becoming extinct. The major species of endangered animals you typically hear conservationists discuss include giant pandas, elephants, gorillas, whales, and tigers. It is estimated only 800 giant pandas exist and less than 650 gorillas remain worldwide.

Animal species become endangered primarily due to human influences. Conservation groups, such as the World Wildlife Fund, work diligently to protect threatened animals and their habitats.

Primary reasons for endangerment include:

1. Habitat Loss – This is the primary cause of endangerment to a species. Each habitat goes through natural change, however, rapid change is hard for a species to endure. Humans are the main cause of rapid change and examples include rainforest deforestation, urbanization, land development, pollution, and climate change due to the release of greenhouse gases.

2. Exotic Species Introduction – Humans may accidentally, or in some cases, intentionally introduce foreign species into a sensitive habitat. New species compete for food, become new predators in the food chain, or bring disease.

3. Overexploitation – This category includes increased activities such as hunting, fishing, and gathering that may threaten a species. Examples include unrestricted whaling, hunting for rhino horns and tiger bones, and gathering of materials for medicines in parts of the world.

What can you do to help endangered species? The primary goal must be to protect the natural habitats where these plants and animals live.

Primary ways you can help include:

1. Protect – Help preserve natural habitats in parks, reserves, and the wilderness. Follow the rules when visiting government parks and be careful not to disturb sensitive areas in the wilderness. Educate people about endangered habitats and plant native species when possible.

2. Recycle – Reduce waste, reuse items, and use public transportation whenever possible to help reduce stress on threatened species and habitats.

3. Conservation Groups – Join a group to help promote the protection of endangered species. You will find others who are passionate about the subject that can provide guidance and resources that will help in your protection efforts.

4. Control Exotic Species – Obey laws regarding the transport of plants and animals as they are usually in place to help protect endangered species or human health. The introduction of exotic species should also be cared for in other situations as well; one example includes the movement of noxious weeds from one locale to another.

5. Be Heard! – Most important of all is to let your voice be heard. Contact your legislators and let them know your opinions regarding endangerment laws and protection, especially with the rapid, present-day increase of urbanization and land development.
