On September 25, 2014, Kate Galbraith authored an article for Foreignpolicy.com entitled "Environmentalism is Dead: How America abandoned its role as leader of the fight to save the planet--and killed a movement." Ms. Galbraith states that environmental agreement numbers spiked in the 1990s and dropped off in the 21st century. She notes that UN Independent Expert on human rights and the environment, John Knox, stated that the 1992 Earth Summit marked a high point for international environmental action. In comparison, Knox said, "It’s . . .hard to see how even something as obviously in the U.S. self-interest as the Montreal Protocol could get through" the U.S. Senate today. Knox did say that countries have made efforts toward plugging the ozone hole, minimizing nuclear testing, and combating pollutants like mercury.
