I believe that the once-Ler should be allowed to cut down the truffula trees.This is because the Thneeds make him rich.It makes more space in the land and it will make more useful stuff.
Firstly the Thneeds make him rich, because some people need thneeds to keep them warm and comfy.The thneeds are nice around cozy,warm fire's.
Secondly, I think that if there were more space in the land the Bar-ba loots can play more game, and there would be some more space to make a road for the cars to drive along.
Finally, the Thneeds make alot of useful things like paper,jumpers,jackets,pajamas,scarfs,rain coats,and all sorts of useful things you can think of.
There fore I strongly believe that the Once-ler should be allowed to cut down the truffula trees because the Thneeds make the Once-ler rich.There would be more space in the land, and the Thneeds make more useful things.
