IMHO, if he wanted to start over, here are my choices for improvement:

1. Greed and meanness are not assets, and few get past them, so don't include crap like that, even if it was a joke or some kind of stupid test.
2. Find a better way for women to have children than a monthly period, or people will suspect you have a mean streak.
3. Make the pits in the mangoes and avocados smaller.
4. Cacao (chocolate) should grow in all climates. Tie the recipes to the bushes so the new people can get started with it right away. Apples are fine, but they're not chocolate.
