Ok I have an answer for this question. Go to Google maps and click satellite view. Look for agricultural fields.
Start in North America. You can zoom to Florida and see orchards. Keep north, further, further, further until you hit northern Alberta. Fields everywhere.
Now go to Ireland, search east, east east. You will see fields all the way from the Atlantic coast to Mongolia, although they get pretty scarce in central Asia but that is to be expected given the climate. But they are still there.
Same thing in China, Japan, Korea, India, Taiwan, Malaysia, Indonesia, etc.
Now go to South America. Well, you’ll see fields in Columbia, Chile, Southern Brazil, basically any place that’s not a desert or rain forest.
Now go to Africa. Morocco check, Egypt check. Now go south of the Sahara. A few disorganized shrubs and that’s about it.
What do they eat south of the Sahara???? Baboon butts?
The land is fertile, the people’s minds are not.
USA for Africa…still going strong.
Bugs?
