90% of USA's farmland is grown to provide food for our meats (cows, pigs, chickens, etc). So if instead of growing all this corn for our animals, it could be used to provide it to people. This is because 90% of the energy the cow consumes from corn is lost through normal metabolic processes. Again when we eat cow, we loose 90% of the energy in the meat through metabolic processes.

Therefor if everyone was a vegetarian then we could use the 90% of land to provide for people.

I however will never stop eating meat, and the USA will never stop raising cattle. Its not a matter or having enough food for people, its a matter of distributing it to the people.

Next all types of food we consume are GM (selective breeding). There is a big difference between genetically modified foods and genetically engineered foods. Your talking about GE foods, where you take genetic information from one organism and splice it into the genetic information of another organism.

If you selectively breed your plants they are now considered GM foods. (Example: If you grow corn and half of your crops are small, while the other half are huge, your going to take the seeds from the large plants and grow them next years harvest.... this is GM). I had a class in undergrad that went over this, but the media mis interperates this material. Even Wiki is wrong on the difference between GE and GM foods.

Over the last 200 years people have been doing that, so every plant/seed we have has been selected in the past years.

I cannot confirm that GM = selective breeding, but that was what i was taught in undergrad so either im definitely wrong, or the technical terms have changed in the last 4 years.

But all in all, yes i think there would be enough food to feed everyone because we would use less farmland in providing food for our cows.
