Dear Once-ler,
I am the Lorax. I speak for the trees. I know that you think that you must make these Thneeds. Do you even think of somehow containing your goo and your smog? I don't think you've realized the pollution it's caused. I'm losing my animals, they're moving away, your factory's polluting day and night, night and day. I hope you'll consider my thoughts on your problem. I bid you good day, and I'll see you tomorrow.
Please Be Concerned,
The Lorax (Emily C.B.)

Dear Once-ler,
You have cut down all the Truffula trees. You should have grown 100 new trees every season. Also if you grew more trees you would not have polluted the air as much. When you cut down all the trees, the Brown Barbaloots didn't have enough fruit to go around. Also you should have seen how many people wanted sneeds so you didn't make more than you need. I'll tell you again. I'll ask you nicely. "Stop Cutting all my truffula trees!"
Sincerely,
Emily P.

Dear Onceler,
Please plant seeds when you cut down trees. That way you have the thneeds and we will have the trees. If you take my advice write me back. OK. Thank you very much for letting the animals live and giving them their land back.
Yours sincerely,
Dylan K
P.S. I'll come over and check in a few days.

Dear Once-ler,
Man, you got to stop this! I'm the Lorax and I speak for the trees. Don't you be cutting down my trees, Dude, The humming fish, bar-ba-lute bears, and teh Swomee Swans are alive too! We need the truffula trees. The humming fish can't hum, barbalute bears can't eat, and swomee swans can't sing. I beg you stop these horible things. We give you a second chance. Stop, Stop, Stop please.
Sincerely,
The Lorax (Elizabeth)

Dear Once-ler,
I am writing you this letter because you are cutting down trees. Some of the Humming fish have died and some of the Brown Bar-ba-loots have been forced to move away. Your pollution is not too bad yet, but I advise you to plant more trees when you are hacking them down. This would be an advantage to you and all the animals that live here. If you planted more trees you could keep hacking them down for as long as you wanted, as long as you kept growing new trees. Another thing I advise you to do is to stop polluting the water. If you only make as much die as you need, you could stop polluting the water a lot. Please consider what I have to say.
Sincerely,
Lorax (Madalyn)

Dear Onceler,
As your business starts to grow and grow you should plant more trees as you go. If you don't your going to run out of trees and the humming fish, swammy swans and barbulotes will have to go too. Plant trees and the trees will filter the smog, keep growing fruit, and clean the water. So all problems will be solved.
Sincerely,
Justin

Dear Once-ler,
Clear out the smog so the Swonee Swans can sing and come back. Plant more Truffula Trees so the Brown Bar-ba-loot come back. Clean the glop out of the pond so the Humming Fish will come and hum once again. The Truffula Trees will give Truffula berries to the Bar-ba-loots again. If you plant more trees you have more thneeds and fresh air, birds singing, fish humming. I hope you do these things.
Sincerely,
Lorax (Chance)
