In the next 40 years, humans will need to produce more food than they have in the previous 10,000 years combined. We will need to do this without causing more damage to natural wildlife than we already have, which in itself is a challenge. World hunger is a big issue, and I encourage you to research it.

there would be no way to enforce that and we would not be able to track it, as well as the fact that we still need enough people to fill in jobs.
