Monsanto's Roundup herbicide has been coming under increasing scrutiny, and it's about time. Glyphosate, the main ingredient in the herbicide, is being reviewed for safety by regulators in the U.S. and Canada, despite having been in use for more than 30 years. Some groups are calling for an outright ban because of problems it causes for plants, animals, and its potential as a cause of infertility or cancer in people.
Meanwhile, Boulder, Colorado has decided to stop using Roundup in public places not because of the dangers of glyphosate, but at least in part because of recent studies showing POEA, an inactive ingredient in the herbicide, is actually more harmful to humans than glyphosate.
The EPA has set a deadline of 2015 for its decision on restricting glyphosate or continuing its use as usual.
Apparently people don't realize that in the U.S., chemicals tend to be treated with an innocent-until-proven-guilty regulatory approach. Roundup is by no means the first chemical that the EPA has taken a second look at, only after decades of harming the environment and people's health.
