Animal Action
In December, the Endangered Species Act (ESA) turned 50. It has rescued many animals and plants from going extinct extinct no longer existing (adjective) Dinosaurs have been extinct for about 65 million years. .
The ESA passed in 1973. A list of endangered and threatened species of plants and animals was made. Harming these species became illegal.
New Perspective
Before the ESA, the federal government encouraged the killing of certain species. It said it did so for “predator control.” For example, from 1916 to 1933, thousands of coyotes were killed in the state of Oregon. The government did this to protect livestock.
MARK NEWMAN—GETTY IMAGESLawmakers first discussed making a change in 1964. A committee investigated the issue. It warned that “times and social values change.”

In 1970, more than 20 million people joined the first Earth Day actions, in support of environmental causes (see “A Growing Movement”). The next year, lawmakers introduced bills that would become the ESA.
Saved Species
The Kirtland’s warbler wouldn’t exist without the Endangered Species Act. It’s a songbird. It nests on the ground beneath jack pine trees in Michigan and Wisconsin. The ESA directed government agencies to care for the trees and plant new ones. These agencies also started trapping cowbirds. The birds invade warbler nests.

Today, governments and corporations are spending money to restore ecosystems ecosystem the living and nonliving things that make up an environment and affect one another (noun) The rainforest's ecosystem includes many unique plants and animals. . They spend billions of dollars a year. There’s so much energy behind this global movement, the United Nations declared the 2020s the Decade on Ecosystem Restoration. The work of saving species is only beginning.
A Growing Movement
BETTMANN/GETTY IMAGESOn April 22, 1970, more than 20 million people participated in the first Earth Day. It was one of the largest public demonstrations in U.S. history. People of all ages took part. They joined events at schools and community sites around the country. They showed their support for environmental issues, such as protecting wildlife.
According to the Library of Congress, the 1970s brought “growing public demand” for better environmental protections. In 1973, the Endangered Species Act passed unanimously in the U.S. Senate. That means no senator voted against it. And it passed in the House of Representatives by a big majority. The final vote was 345 to 4.
