He uses tons of chemical fertilizer not pesticides big difference.

Isn't nitrate run off from chemical fertilizer a big polution problem for rivers and lakes?

It's called aquatic hypoxia: http://arstechnica.com/science/news/2008/08/the-growing-prob...

You can't feed 6 billon people on organic farming.

Plenty of studies suggest that organic can be as or more productive than chemical intensive. A quick google produces the following from the University of Michigan: http://www.ns.umich.edu/htdocs/releases/story.php?id=5936

That wasn't the point the OP said that the Green revolution was great for the environment. That's not strictly true there are some good things but also bad.

Is anybody arguing that you can? Is anybody championing organic farming because they think it will feed the world?

Sure they are. Any progressive, liberal, green, whatever, person who corners you in a coffee shop and laments how evil farmers are for not doing organic farming. That guy, you know him. He better think it's going to feed the world. I'd rather believe he's stupid than believe he's genocidal.

Maybe the progressive, liberal, green people I've met are more nuanced. Most realize that organic farming is inherently less efficient (in calories per acre farmable land) and aren't putting forward as a solution to world hunger.
