Tropical forests are filled with exotic flowers, life and food
All you need is to learn what to use, how to use and when to use the varies plants, trees, fruits or nuts as well as how to prepare to turn nature into delicacy or medicine.
Many fruit trees need no fields. For example banana plants grow in wild jungle amidst dense growth without need for pesticide or herbiced or any other chemicals. The same applies for Mango trees and most other trees. Fields only are needed for vegetables or salads and a few other smaller plants.
