I'm a big fan of pesticides, fungicides, insecticides and genetically engineered food. With the population on the rise and land at an absolute premium we need all the food we can get out of the Earth sans the bugs and disease that eat and kill them.
If you're ever curious about the miracles of G.E. food look up "Dwarf Wheat." Science has given the species the ability to shore up a precarious food supply.
Thanks to things you've listed more of us are able to eat and better. Any argument to the contrary seems, frankly, invalid. More people are being better fed. Period.
