In addition to global climate change…

In the United States, there’s this stereotype that different human populations worry about different environmental catastrophes. College-educated white suburbanites, so the stereotype goes, worry more about global climate change — perhaps because they are more aware of how much energy it takes to power their many automobiles, and to heat their large homes. Communities of color and working class whites, so it is said, worry more about toxics in the environment — perhaps because people of color and working class people are more likely to be exposed to more toxic substances in the places they live and work.

College-educated white people have tended to be dismissive of the threat of toxics in the environment, at least in comparison to the threat of global climate change. Global climate change has the potential to cause another “great extinction” and to decrease human chances of survival, whereas toxics in the environment don’t have the potential to do as much damage.

But I think we all should start worrying more about toxics in the environment.

According to a BBC article titled “Pesticides linked to bee deaths found in most honey samples,” a recent study published in Science shows that neonicotinoids have been found in three quarters of honey samples from around the world (from every continent except Antarctica). The widespread presence of neonicotinoids is especially troubling, because they were found in places where the chemicals have been banned for several years.

When asked by the BBC to comment on the article, Dave Goulson, professor of biology at the University of Sussex, said: “Entire landscapes all over the world are now permeated with highly potent neurotoxins, undoubtedly contributing to the global collapse of biodiversity.”

The collapse of biodiversity is bad enough. But consider, too, that if we humans kill off major pollinators, there’s a potential cascade effect that could drive many flowering plants towards extinction. So if you’re looking for a cause of the next “great extinction,” or if you’re just looking for another reason to lie awake at night and worry — look no farther than toxics in the environment.
