are many renewable resources that are being depleting. We are using more than we can put back in the manhandled world. Trees
for example are being cut down, and in this state there is a law that you must plant a tree for every tree you cut down. This
is a great law, but it takes many years for a tree to grow. In the Amazon we are cutting trees down at an alarming rate. Another
problem with cutting down trees is that we are clear-cutting, a technique where logging companies or contractors for neighborhoods
cut down every tree. Often down have enough room to plant the trees they have chopped down for the neighborhoods. Sustainable
forestry is a way better alternative to clear-cutting. In this method certain trees a targeted for cutting. Cutting some trees
while leaving others untouched. This leaves the economical system to preserve old growth.
