This poem comes from Autumn Leaves:
Hear then a tale of questionable strategy
Involving a wondrous creature.
Results were almost near tragedy,
Species extinction, Nature’s own sad teacher.
Their existence brings about mixed feelings
As they quietly pass on parade,
Slowly plying changing ocean currents,
Passing near man unafraid.
Gentle and playful, they offer no cause
For unfounded fear or alarm,
Never inflicting pain in their watery domain
While displaying whale-loads of charm.
The solution was always very simple,
Very easy to understand.
You see, while we’re able to travel our oceans,
They’re unable to travel on land.
Then let’s leave these great gentle wonders
In care of Neptune’s safe keep
To breed and play, live and die, peacefully,
Inside blue marvel of their deep.
