Yes, messing with things should be done carefully. But one shouldn't forget how much bad things are happening every day: - first of all, the continuous threat to Eco-systems from invasive species constantly spread around the globe by carelessness. - one especially bad example is the breeding of pets which are basically sick by design. A lot of dog races are a prototypical example, but also cats and especially many fish breeds. So yes, genetically modified plants are a bit frivolous, but one should push more to fight against the things listed above, happening so routinely.
