Sense Sonnet - Chiller

Changing Diet

The koalas do only eat
The leaves from the eucalyptus tree,
Which really is an awesome feat,
Cuz quite toxic these leaves do be.
Researchers have researched the why,
And found koalas have evolved
So that they can detoxify
Eucalyptus leaves - problem solved!
But in Australia these trees do
Be getting cut down more and more.
Koalas have less leaves to chew.
Is this end what they evolved for?

In time koalas may be gone -
No eucalyptus to chew on.
