And More

"What's more," snapped the Lorax. (His dander was up.)
"Let me say a few words about Gluppity-Glupp.
Your machinery chugs on, day and night without stop
making Gluppity-Glupp. Also Schloppity-Schlopp.
And what do you do with this leftover goo?...
I'll show you. You dirty old Once-ler man, you!
You're glumping the pond where the Humming-Fish hummed!
No more can they hum, for their gills are all gummed.
So I'm sending them off. Oh, their future is dreary.
They'll walk on their fins and get woefully weary
in search of some water that isn't so smeary."
