Study: GMO crops lead to superweeds lead to more pesticide use

One reason GMO crops were developed was to reduce pesticide use. Unfortunately, a new study has found that exactly the opposite is happening when GMO crops are grown in subsequent years. Superweeds, those that are resistant to pesticides, are created, and more and more chemicals are used in effort to kill. It's basic evolution: survival of the fittest superweed.

Nation of Change explains:

Genetically modified organisms (GMOs) require more pesticide use on crops, say the authors of a 16-year study published in Environmental Sciences Europe. According to the researchers, 527 million pounds of a toxic herbicide have inundated farmlands since 1996. What's more, this abhorrent amount is much greater than that promised by Monsanto, which claims that GM crops require smaller doses of herbicides like the company's best-selling Roundup Ready.

This study found, however, that although farmers did reduce Roundup Ready use by 2 percent between 1996 and 1999, herbicide use resurged with a vengeance thereafter. This was a result of the emergence of "superweeds" that resist herbicides, requiring farmers to use more of it with each application.

Now we don't only have to worry about the negative effects of GMO crops to our health and environment, we also have increased pesticide use to be concerned about as well.
