Never Lasts Forever

Time travels backward through the portals of my mind,
while viewing nature's finest at the local zoo, I find,
within each generation, careless attitudes eschew,
forever gone, the last living creatures bid adieu.

Plastic's great convenience adds misery and waste,
fabricated food supplies no nutrients or taste.
Consumers reach for endless happiness and love,
ageless beauty creams offer none of the above.

If I only knew the answer that was staring back at me,
then questions asked today would not haunt repeatedly.
If ever life appears too long to understand,
then 'never' slips through fingers as forever grains of sand.
