“Find milkweed to lay eggs in, or it's time to emigrate...”
But when milkweed became rare,
Nature lovers everywhere
Cried “Save the monarchs,” and
Planted milkweed in the land.
But the milkweed they could find
Was a somewhat different kind:
It grew and matured quite late,
And thus doomed the monarchs' fate:
For their larvae, sad to tell,
To fall's frosts as victims fell...
And thus you will often find,
Trying to change Nature's course,
Though with the best intent in mind,
You have only made it worse...
