Overuse of Bioengineered Corn Gives Rise To Resistant Pests

An anonymous reader writes "Though warned by scientists that overuse of a variety of corn engineered to be toxic to corn rootworms would eventually breed rootworms with resistance to its engineered toxicity, the agricultural industry went ahead and overused the corn anyway with little EPA intervention. The corn was planted in 1996. The first reports of rootworm resistance were officially documented in 2011, though agricultural scientists weren't allowed by seed companies to study the engineered corn until 2010. Now, a recent study has clearly shown how the rootworms have successfully adapted to the engineered corn. The corn's continued over-use is predicted, given current trends, and as resistance eventually spreads to the whole rootworm population, farmers will be forced to start using pesticides once more, thus negating the economic benefits of the engineered corn. 'Rootworm resistance was expected from the outset, but the Bt seed industry, seeking to maximize short-term profits, ignored outside scientists.'"

Diversity is the key. (Crop rotation is just one example.) The whole "mega-scale, mono-culture" approach to farming is flawed, and these GMO tweaks are just prolonging its inevitable demise. The future lies with smaller-scale, multi-species farms which more closely mimic the patterns found in nature.

For example, put multiple crops in a single field, alternating several rows of each (depending on what equipment you're using), and interspersed with "islands" of other species whose purpose is to provide habitat for the predators of your pests. You might not get quite as much yield, but if you don't have to spend a dime on pesticide, you'll still come out ahead.

It's a lot more sophisticated than I can explain here, but there are plenty of people doing this already, and it is growing in popularity. There are many different methods being developed, most of which fit under the umbrella of "permaculture" or "holistic management". Look at what Joel Salatin is doing at Poliface Farm in Virginia, or what Colin Seis is doing with "pasture cropping" in Australia, as just a couple of prominent examples.

There are better ways to produce our food and fiber, it's just going to take a while to revolutionize the entire industry.
