This short poem discusses environmental destruction, stating that humanity will not realize the damage done until all rivers are polluted, all trees cut down, and all fish caught, with no resources left. The poem suggests we are harming the environment without understanding the consequences until it is too late.

Only when the last
river has been
polluted, and the
last tree been cut
down, and the last
fish been caught,
we will realize what
we have done.
