Read between the lines: "easier to grow" means more resistant to herbicides and pesticides. Furthermore, if we have just found out how good they are for us (that is, nature has done an excellent job without our help), why would we want to mess with them?
Remember, the only way to avoid Genetically Modified Organisms is to buy ORGANIC. I started buying organic chocolate a long time ago. Start doing that yourselves if you have not done that already.
