The United States of America has laws regarding air quality, water quality, protections for national forests, national parks and endangered species. We are a country of laws. We have agencies ALREADY in place that know what the Climate Crisis is, report on it regularly and are eager to end the suffering of Americans because of it.
THIS IS NOT NEW!
American scientists were among the very first to carry the warning and helped the American people develop "Earth Day."
Get over the idea this is something new, it is not. The problem is that the USA has never risen to the demand for change required to end this crisis and reverse the effects of severe and growing threats of climate.
