Should the once-ler be aloud to cut down the trees?

I strongly believe the once-ler should not cut down the trees. Its because the barbaloots will have no shade, no food and also not enough oxygen.

Firstly the once-ler should not cut down the trees because the barbaloots will have nothing to eat and will have to leave the land. Also food helps us to survive.

Secondly because the barbaloots wont have any shade. Trees give us shade to protect us from the sun. If there were no shade we would have sunburn and the worsts SKIN CANCER!!! which you could die from.

Thirdly because the barbaloots wont have enough oxygen. Oxygen helps us to breathe. If the trees were cut down the barbaloots wont be able to breathe properly.

Therefore I strongly believe the once-ler should not cut down the trees because there will be no food, no shade and also not enough oxygen.
