GMOs provide a way to continue to realize the benefits of the Green Revolution without all of the chemical-related downsides. Yes, but there very well may be other downsides. A lot of the utopian ideas for GMOs basically involve creating invasive species. We here about the potential of making species that can easily grow in areas where they couldn't grow at all before. But doing so could well pose an environmental risk (if these end up growing so well in areas that they end up disrupting the ecosystem). It might seem strange to think that too many edible plants could cause a problem, but it wouldn't be the first time (Kudzu is a good example). We're also not nearly at that point yet with current GMOs, but it seems to be what a lot of people are advocating. It'd be nice if we thought of the environmental downsides ahead of time, so that we don't keep saying "we now understand the environmental downsides of the tech we were using 30 years ago; but this new tech should be just fine" every few years.
