Brazil Farmers Say GMO Corn No Longer Resistant to Bugs

Brazilian farmers say their GMO corn is no longer resistant to pests, Reuters reported Monday.

The Association of Soybean and Corn Producers of the Mato Grosso region said farmers first noticed in March that their genetically modified (GMO) corn crops were less resistant to the destructive caterpillars that “Bt corn”—which has been genetically modified to produce a toxin that repels certain pests—is supposed to protect against. In turn, farmers have been forced to apply extra coats of insecticides, racking up additional environmental and financial costs.

The association, which goes by the name Aprosoja-MT, is calling on Monsanto, DuPont, Syngenta and Dow companies to offer solutions as well as compensate the farmers for their losses. In a release posted to the Aprosoja-MT website, spokesman Ricardo Tomcyzk said farmers spent the equivalent of $54 per hectare to spray extra pesticides, and that the biotech companies promised something they didn’t deliver, “i.e. deceptive advertising.” (via Google Translate)

But Monsanto, et al are unlikely to accommodate the farmers. According to Reuters, “seed companies say they warned Brazilian farmers to plant part of their corn fields with conventional seeds to prevent bugs from mutating and developing resistance to GMO seeds.”

Earlier this year, a similar problem arose in the U.S., when scientists confirmed that corn-destroying rootworms had evolved to be resistant to the GMO corn engineered to kill them.

The industry response to such loss of efficacy is not to encourage biodiversity, but to further modify the organisms, according to the nonprofit GM Watch.

The case of Brazil is an example for an overall trend showing that nearly twenty years after the start of commercialization of Bt crops, there are problems in several countries growing this kind of genetically engineered crop. Industry tries to tackle this issue by commercialization of so called “stacked events” that produce several different Bt toxins. The best known example is Monsanto’s SmartStax maize that produces six different Bt toxins.

Another unintended outcome is almost certainly an increased use of pesticides, as has already happened in Mato Grosso.

Ethics investigations have been opened into the conduct of senior Trump appointees at the nation's top environmental agencies.

The two investigations focus on Environmental Protection Agency (EPA) Administrator Andrew Wheeler and six high-ranking officials in the Department of Interior (DOI), The Hill reported Tuesday. Both of them involve the officials' former clients or employers.

"This is demonstrative of the failures at the very top of this administration to set an ethical tone," Campaign Legal Center Ethics Counsel Delaney Marsco told The Washington Post of the DOI investigation. "When people come to work for government, they're supposed to work on behalf of the public. It's a betrayal of the public trust when senior political appointees seem to give privileged access to their former employers or former clients."

We've known for more than 50 years that smoking cigarettes comes with health hazards, but it turns out those discarded butts are harmful for the environment, too. Filtered cigarette butts, although small, contain dozens of chemicals, including arsenic and benzene. These toxins can leach into the ground or water, creating a potentially deadly situation for nearby birds, fish and other wildlife.

Five years ago this week, an emergency manager appointed by then-Michigan Gov. Rick Snyder made the devastating decision to save money by switching Flint's water supply over from Detroit's water system to the Flint River. Seen as a temporary fix, the new water supply was not properly treated. High levels of lead leached from the old pipes, poisoning a generation of Flint's children, and bacteria responsible for an outbreak of Legionnaires' Disease killed more than a dozen residents.

Did you know that more than a third of food is wasted or thrown away every year? And that only 25 percent of it would be enough to feed the 795 million undernourished people in the world? That's why today is Stop Food Waste Day, a chance to reflect on what you can do to waste less of the food you buy.

Stop Food Waste Day is an initiative of food service company Compass Group. It was launched first in the U.S, in 2017 and went global the year after, making today it's second worldwide celebration.
