A Thought.

Predatory animals are frugal by nature,
they are born with an innate understanding of limits,
of odds,
of boundaries.
They understand that starvation could come at any time,
so they waste as little as possible.

They fight when necessary to secure a mate,
or to protect themselves from other predators,
or from competition for food.

They rarely kill without reason,
and rarely kill that which they are unable to eat.

The human is the only species that kills its own for fun and profit.
We are not predators by nature,
just prey with better equipment.
