What are some things that the government is doing to damaged ecosystems?

There are many things that the government has done and is still doing in the aspect of environment conservation. The most that they do is implementing stricter laws for environmental protection like the Clean Air Act, Clean Water Act, Toxic Substance Control Act, and many more. This is to ensure that the inhabitants of our environment can enjoy a safe and healthy living. For damaged ecosystems, the government is actively supporting projects about the revitalization of wastelands and coral reefs by shelling out generous amounts of money. Apart from this, they also conduct their own projects of tree-plantings and clean-up drives. The government also helps the ecosystems that are aggravated because of industrialization projects coming from both private and public sectors through arbitrary actions.
