explain the purpose for an environmental agreement between the united states and china. what other steps has the united states government taken in combating global challenges?

China is the biggest emitter of greenhouse gases in the world. With The United States being but that far behind, both countries have negotiated a deal to reduce their greenhouse gas output, with China agreeing to cap emissions for the first time and the US committing to deep reductions by 2025.

There is an ongoing debate about the appropriate role of government for solving environmental problems. However in a major achievement for environmentalists, the U.S. Environmental Protection Agency (EPA) was established in December 1970, bringing together in a single agency the many federal programs to protect the environment.
