Synthetic chemicals as agents of global change

Though concerns about the proliferation of synthetic chemicals – including pesticides – gave rise to the modern environmental movement in the early 1960s, synthetic chemical pollution has not been included in most analyses of global change. We examined the rate of change in the production and variety of pesticides, pharmaceuticals, and other synthetic chemicals over the past four decades. We compared these rates to those for well‐recognized drivers of global change such as rising atmospheric CO 2 concentrations, nutrient pollution, habitat destruction, and biodiversity loss. Our analysis showed that increases in synthetic chemical production and diversification, particularly within the developing world,…
