Agroforestry is defined as any agriculture that centers around the conservation of trees. There is a full business to the conservation of trees since there are a lot of reasons to keep trees alive. If trees do not regrow, that’s less for us to use as paper for books, magazines, etc. when the recycled ones aren’t enough for demand. Trees are also good sources of oxygen for the planet, and for the animals that rely on oxygen.
However, if trees are allowed to regrow and allowed to live, we will have a better chance of keeping the planet hospitable to us and to the rest of the flora and fauna that live on earth alongside us. Trees are needed, and if there’s a business to keep it alive, then there it is.
