Those of us who care about the natural world, especially current assaults to it from all sides, have long been worried about the short- and long-term effects of pesticides and herbicides on native flora and fauna. And, of course, we also need to be worried about the effects of these chemicals on humans, especially more susceptible groups like children and women in their child-bearing years. A study released in the October 6 edition of the journal Science provides alarming evidence that agricultural practices throughout the world need to be re-examined. Immediately.
You’ll find a good description of this study in this recent article in Nature. In this new study, scientists collected 198 honey samples from around the world. They detected at least one of the five common neonicotinoids they tested for on every continent with honeybees, including remote islands with very little agriculture.
Neonicotinoids target the central nervous systems of crop-destroying insects, but — theoretically anyway — do not have the same effects on humans. However, an increasing number of studies are demonstrating how these pesticides are negatively impacting non-target insect species like honeybees — and wild bees. Increasing evidence shows that our well-documented decline in pollinator populations is associated with the massive increase in the use of these poisons by the agriculture industry.
It is true that in all samples, levels of these poisons were below the minimum levels established by experts to be safe for human consumption. However, I would argue — strenuously — that these determinations were not the result of rigorous science. Heck, I would argue that the presence of any amount of these poisons is dangerous to humans. Were cumulative effects considered, for example?
I ask because of the results of another alarming study recently published in JAMA Internal Medicine led by Harvard scientists. This one notes a strong association between women struggling with fertility issues and their high consumption of fruits and vegetables laden with pesticides. These women are no doubt trying to improve their nutrition by consuming more fruits and vegetables that they are buying in their local supermarkets. But some of these crops (not organically grown, of course) are so coated in pesticides that when eaten frequently, show up in the bloodstreams of those consumers. I submit that it is only a matter of time before scientists produce evidence of similar effects specifically associated with so-called “safe” neonicotinoids.
What can we do? I think we need to make it a priority to increase the availability of organically grown produce to all of humanity. In the US, we must speak with our wallets and refuse to buy poison-laden produce. As the popularity of organically grown produce increases, prices for it will fall. Every other corner of every neighborhood — suburban or urban — should showcase a community garden where organically grown crops are produced by neighbors for their local consumption. Every able-bodied suburbanite with a yard dominated by a poison-laden, non-native lawn should convert that waste of space into small, beautiful gardens full of food and flowers — all grown without pesticides.
Organically grown produce and flowers do not look as pristine as poison-coated ones, but, my friends, you get out what you put in; you get what you pay for. And future costs to future generations must immediately become a significant factor in this calculation.
