If you owe land you still don't owe the skills to grow food without irrigation & fertilizers. It doesn't mean that you can defend it and the harvest against 8.35 bn hungry mouths. When food starts running out when overpopulated, it's just all over. We should grow food because it's right.
#Extinction. How does it work? 1. Population is too small. Die off due to lack of reproduction & inbreeding. 2. Population is too big. Resources are overused & can't grow back in time. Competition destroys last resources. #Overpopulation case study: Reindeer on St. Matthew Island
