Final answer:
During his tenure, President Trump withdrew the U.S. from the Paris Agreement and eased environmental regulations, indicating a shift to support industry and fossil fuels.
Step-by-step explanation:
The environmental policies of the Trump administration showed a decisive shift from those that came before, particularly in the realm of international environmental agreements and regulations on industries. Notably, President Trump pulled the United States out of the Paris Agreement on climate change, a cornerstone international treaty aimed at combating global warming and reducing greenhouse emissions. His administration also loosened regulations like fuel efficiency standards for automobiles and curtailed the enforcement of emissions controls, signaling a departure from the previous focus on environmental protection towards an emphasis on industry and fossil fuel development.
