Soon enough the world WILL reach a 'supply cap'.
How this works can be found in a lot of ecosystems.
1-Food is readily/easily available (Not true everywhere of course)
2-Population grows exponentially
3-Population suddenly exceeds available food.
4-RAPID decrease in population (Famine)
5-Population is suddenly much smaller
6-return to step 1
We (industrialized nations) are at step 2.
'Third world' countries are at about/almost to step 3. In some/lots of places food is brought and distributed by humanitarian aid groups (from industrialized nations). This will not work once the industrialized nations start to have serious food supply problems.
