Quite to the contrary the poster of this comment is very wrong you can in fact eat many trees you can eat the inner bark of many trees you can eat the leafs and early seed pods of many trees many trees produce grain and calories at the same rate of barley or rye.

This is before any improvement work is done.

There are fruit trees that produce large amounts of sugars good for flavoring and cooking, there are trees that produce edible seeds like beech walnut acorn hackberry and many more, there are trees that produce edible leaves like mulberry, redbub, and cedar.

Bigger plants make more energy more energy means more food.

Even wood can be turned into a sustainable source of protein and fat by using it to feed fungi or insects.

Also fire doesn't kill forests that are cared for properly, every forest type protects itself in different ways, if you trees burn or die it is simply becuse you used the wrong type of trees

Classic farming is something that you can only put a little effort in because the system is small, with agroforestry you can continue to get sustainable sources of food through the whole year at only the cost of effort 👌
