Eat less meat?

A prolonged drought in the US threatens corn yields and could push global cereal prices to new record highs. http://news.independent.co.uk/uk/this_britain/article3298372.ece

I wonder if we would be better to change our diet to more cereal, eating it directly, rather than feeding it to animals and then eating them. According to http://veg.ca/content/view/133/111/#diet
a meat-based diet requires 7 times more land than a plant-based diet.

OK, so I'm pretty much veggie, apart from the fact that I do now eat fish, but we could all easily eat less meat, without in any way lowering our quality of life.
