Increased use of herbicides will mean the loss of wild plants, which will mean fewer insects - which in turn will mean a reduction in the birds and animals that eat them. Roland Pease There were recent trials for example in Britain where they showed that insect populations, weed populations and bird populations in GM fields had been damaged. The point there is it's not actually the crops directly affecting those things, but because the crops allow more vigorous, herbicide weed control, the knock-on effects of that weed control have been on the number of weeds, as you'd expect, but also the number of insects feeding off the weeds and the number of birds feeding off the insects.
