The US Endangered Species Act is a Timeline Event that can occur between 1974 and 1976.
While the event is happening, the commodity prices of logs, lumber, and furniture is increased by 25% due to the new restrictions causing the US logging industry to shrink.
The Endangered Species Act began as the Endangered Species Preservation Act of 1966, which directed government resources to preserving habitats for endangered animals and encouraged (but didn't require) public organizations to take conservation steps as well. Although the act was amended in 1969 to prohibit importing endangered animals, US president Richard Nixon considered the conservation efforts inadequate. Congress responded by creating the current Endangered Species Act, which applies to citizens as well as the government itself.
