What Made Us Greedy?

I’ve always loved wildlife documentaries, especially those about mammals. There’s something comforting about their simplicity. Each animal has three clear goals: feed itself, defend its territory, and reproduce. Survival is the whole story.

Watching them, I often wonder: is it better the animal way or the human way? What really made us different?

The usual answers come quickly — language, fire, maybe even divine intervention. But those are old explanations, already chewed over. After some time, I stumbled on a different thought: perhaps it’s our ability to preserve that made us different.

Take food, the most basic resource. Mammals hunt or graze only when they’re hungry. They don’t stockpile. Lions kill one deer, eat until they’re full, and then walk away. The leftovers go to hyenas and vultures. Not generosity, just necessity. They don’t have freezers. And maybe, in a strange way, the absence of freezers makes them gracious.

Now imagine a man in the same situation. He wouldn’t stop at one deer. He’d kill twenty‑seven because it was easy. He’d eat half, toss some away, and cram the rest into a freezer. Then he’d complain the freezer was too small — and keep hunting anyway. That’s us. Preservation turned into hoarding, and hoarding turned into greed.

Even vampire bats show restraint. They sip blood but avoid killing their host, because tomorrow’s dinner matters more than today’s feast. It’s a clever survival trick. Too bad their victims often die later from rabies or poor mouth hygiene. Still, the bat’s logic is clear: don’t destroy the source of tomorrow’s meal.

Humans sometimes behave like vampire bats too. I remember the film Thank You for Smoking. The tobacco spokesperson argued that companies had no incentive to kill their customers. In fact, it was in their best interest that smokers lived long lives — so they could keep buying cigarettes. Awkward, but logical. Preserve the prey, preserve the profit.

And that brings me to a troubling thought: is there really incentive to cure diseases? Once a disease is cured, the revenue stops. Preservation, in this case, means keeping the illness alive just enough to sustain the business.

Animals survive. Humans preserve. Somewhere between the freezer and the profit margin, greed was born. The ability to be greedy made us greedy.
