Absolutely. It's had a very, very positive impact on the environment. I'll give you an example. I sort of touched on it in my presentation around the herbicide-tolerant crops.
By the way, you can get herbicide-tolerant crops through traditional breeding and other techniques, but the GM ones dominate the market today.
It allows for a much improved and more effective way of controlling weeds. It's also very compatible with the trend to go with minimal-till farming or no-till farming; in other words, the fields are not getting plowed. It allows the stubble from the previous crop to remain in the soil, which has a beneficial impact in terms of vegetative content of the soil, the health of the soil, and so on. It also has some impact, so I'm told, on water evaporation. It's reduced, compared with that of a plowed field.
Also, if you think about a tractor plowing a field and burning up its diesel and all the rest of it, if you don't have to plow the field, you will save a bundle on diesel, and we all know about greenhouse gases and those sorts of things.
This is just one example of where there's definitely a benefit.
