That just seems very unlikely. Forty -five years ago Paul Ehrlich wrote "The battle to feed all of humanity is over. In the 1970s hundreds of millions of people will starve to death in spite of any crash programs embarked upon now. At this late date nothing can prevent a substantial increase in the world death rate." Even if you agree with his central thesis, its fair to say that we're two generations removed from 1970, and we're not seeing what he predicted. And since 1970, the world hunger situation has almost uniformly improved. Now I certainly don't believe that the Earth has unlimited resources, and there is a finite capacity of arable land, but I think you may be very premature.
