Advocates and conservationists are hopeful that a Biden administration will better protect animals in the U.S. In 2019, Trump made changes to the Endangered Species Act that made enforcement more difficult. Biden’s administration may reverse some of these rollbacks. The president-elect has a strong record on wildlife issues. As a senator, he co-sponsored animal welfare bills. His incoming administration will need to consider climate change, enforce animal welfare violations, and improve the health standards for farmed animals.
