How much nature should America keep?
The United States has lost the equivalent of nine Grand Canyon national parks, or 24 million acres (9712455.41 hectares) of natural area, between 2001 and 2017 due to agriculture, energy development, housing sprawl and other human factors, making the country more vulnerable to the impacts of climate change, according to a report. The study by progressive think tank Center for American Progress titled "How Much Nature Should America Keep" said the U.S. needs to set a goal to protect 30% of land and oceans by 2030 to stem the rapid decline of natural areas, which will protect the country from the worst impacts of climate change and wildlife extinction.
