Increase in Use of Synthetic Chemicals

Caption

Three graphs show the rates of increase in the use of synthetic chemicals in recent decades relative to other agents of global change such as nitrogen fertilizer and CO2. The middle graph (red) shows increases in chemical diversity in the US and globally; the right graph (green) shows global trade values as a proxy for the mass of chemicals.
