Despite the use of various contraceptives, the world population keeps ballooning. Will there come a time that all food will be extinct and we cannot feed ourselves or what is the way forward because we are tilling all the virgin lands etc .
It of course depends on many factors, climate and our behavior mostly, the later of which we can control. Producing meat as a source of food is moronic, we make soils go depleted 15 times faster then when growing crops. We lose 90% of the energy when converting from crops to meat and from meat to energy in our cells. We use enormous amounts of water to keep he meat industry going, which might be the biggest concern we have.
If we would eat only crops we grow we could free up massive amounts of land and stop the soil erosion. The animal industry emits more green house gases then all vehicles on earth, it is the worst possible solution which also speeds up the climate issue, droughts etc . We could save large amounts of water as well and by doing this we will create a sustainable food source capable of producing food for 8 Bil.
This will give us the time to let human growth stabilize and we can build grow sky scrapers and produce food vertically so there is no limit on how many we can feed
