What is the Endangered Species Act?

The Endangered Species Act (ESA) is a landmark U.S. environmental law passed in 1973. It provides a framework for the protection and recovery of imperiled species and their ecosystems, both domestically and internationally.

What are the biggest threats to endangered species?

The primary threats to endangered species include habitat loss and degradation, climate change, pollution, invasive species, and overexploitation (e.g., poaching and unsustainable fishing). These factors often interact, exacerbating the risks.

How to Observe Endangered Species Day

  1. Make a donation

    There are thousands of charitable organizations dedicated to conserving endangered species, and they all could use your help. These organizations exist at national and local levels as well, so you can choose how far and wide your money goes.

  2. Volunteer at a local nature center

    If you can spare the time, find a nature center near you and volunteer. Take the opportunity to learn something new about this wonderful planet we live on, and learn how you can make sure it’s in good shape for the future. Most nature centers offer helpful literature, and those who work there are always ready for a chance to talk about their work. If you’re interested volunteering could turn into a regular hobby!

  3. Go on a nature walk

    Take time on National Endangered Species Day to see for yourself what the natural world looks like, right in your backyard. See if you can spot all the creatures that make their homes with you, and try to figure out the best way to help your local ecosystem work.

Why Endangered Species Day is Important

  1. Healthy planet

    Every animal is a vital link in its own respective food chain. Removing any link has disastrous effects on other animals, humans, and the planet in general. The key to making sure that human history continues is to make sure we live on a healthy planet, and in order to do that, we must allow other animals to live and thrive along with us.

  2. Bald eagles: A success story

    The pesticide DDT once posed a threat to America's bald eagle population. The U.S. banned DDT in 1972. The Endangered Species Act took effect a year later. Bald eagles recovered by 2007 and no longer occupy a spot on the endangered list.

  3. Research

    When it comes to studying disease or biology or natural history, it’s not enough to study fossils and other humans. Studying the animals who share our planet allows us to form a deeper understanding of the way life works. If a species goes extinct, there is no real way for us to truly understand how they impacted the planet. After all, dodo saliva could have been utilized as a natural antidepressant, but since they all died out several centuries ago, we’ll never know for certain.
