Today the sky is filled with birds,
Tomorrow not a one is heard.
The oceans which once teemed with life,
Now filled with plastic and oil, running rife.
When the last fish is caught, the last bird is shot, the last tree is cut, will they notice then? When there's no clean water left for them? When there's no food to feed their kin? Only then will they notice, and by then, it will be too late.
