I think the idea that improved varieties and chemicals from Monsanto are going to end world hunger is laughable. We are going to continue to lose growing acres and non-renewable water.
Drought tolerance genes. Yield enhancement genes. Nitrogen efficiency genes. These are real things that will all likely be available by the end of this decade. Use your imagination, that is what companies like Monsanto are doing. Also, Monsanto is not working on improved chemicals, other companies are.
As to the laughable part, are you suggesting that companies like Monsanto are not responsible for this:

I get that you don't like Monsanto. I don't love them, but they are a great American company and the technology that they have developed in agriculture will help to feed a growing world.
What do you think the answer to feeding a growing world is?
