Maybe my pun about meet/meat confused you but the problem definitely isn't limited to meat production. You should see the quantites of pesticides/fertilisers/treatment agents used in the extensive culture of plants. The question holds, if you don't intend to back current production levels that are only possible through over intensive exploitation to the detriment of the product and it's growing medium, what alternatives are there to meet current demand for food in general?
