The video above shows a summarized evaluation of human kind worries for feeding 2 billion more people by 2050 considering the available lands, our feeding habits and production technology.


The map below shows, in green the regions that produce food consumed more directly by humans;  in orange the regions that produce the same amount of food for humans and animal feed; and in red the lands that are primarily used to produce animal feed. (Both photos, source:  University of Minnesota/Institute on the Environment/Global Landscapes Initiative).

Not all arable land is used for food production for humans. Much of the arable land is used to produce animal feed.

Green: people.  Red: animals.

In another blog, in Portuguese, there are comments on  "eating more cereals than meat"  (healthier and more sustainable). Access:
