Food crisis?

Costco and SAM's club are limiting the rice per household.

Recently I've read Hominids and Humans by Robert J Sawer and now I am half-way through Spin by Robert Charles Wilson.

Then I started thinking that which one will help us in the near future: parallel universe with an identical earth (but pristine) or a terra formed Mars....from the purely economical perspective it's easier to do business with the parallel universe...we just need to open the "portal" and you walk right into the universe. Terra farming the Mars is economically and technologically (unless of course there is a time dilation) difficult. But it's lot of fun to think about.
