"Eat less meat" is not a good solution since industrialized monocrop agriculture has tons of problems on its own like topsoil erosion and air/water pollution. The problem doesn't lie in any one single food, but in commercial food production in general, be it livestock or agricultural. If you want to help against that, the best option would be to support sustainably raised meat and vegetables from local farms by going to farmers markets or eating out at farm-to-table restaurants. If possible, plant your own vegetables, raise your own chickens or hunt. Avoid buying from the big food producers, like Kraft, Tyson, PepsiCo or ConAgra
