Tragedy of the commons facts for kids
The tragedy of the commons is a problem that happens when many people share a resource. Even if everyone wants to keep the resource good, it can get worse because each person acts in their own interest.
Imagine a shared park where everyone lets their dog run free. Each owner thinks their dog won't cause much trouble. But if many dogs run free, the park can get ruined for everyone. This idea helps us understand how shared things can get damaged.

What is the Tragedy of the Commons?
This idea describes how a shared resource can be used up or damaged. It happens when many people use something together, but no one is fully responsible for it. Each person tries to get the most for themselves. This can lead to the resource being ruined for everyone.
The idea was first written about by William Forster Lloyd in 1833. He talked about farmers who grazed their cows on a shared piece of land. This land was called a "common."
Each farmer wanted more milk and meat, so they added more cows. One extra cow helped that farmer a lot. But if every farmer added more cows, the land would get overgrazed. This meant there wasn't enough grass for any cows, and the land was damaged. Everyone lost out in the end.
Garrett Hardin's Article
In 1968, a scientist named Garrett Hardin wrote an important article. It was published in a science magazine called Science. He called this problem "The Tragedy of the Commons."
Hardin used the old idea to explain modern problems. He showed how shared things like clean air or oceans can be harmed. People might think their small actions don't matter. But when many people do the same small thing, it adds up to a big problem.
Why is This Idea Important?
The tragedy of the commons helps us understand many real-world issues. It shows why we need rules or ways to manage shared resources. Without good management, these resources can be lost.
Protecting Our Environment
This idea is often used when people talk about the ecology and the environment. For example, the Earth's atmosphere is a common resource. If many factories release pollution, the air quality gets worse for everyone. No single factory wants to ruin the air, but their combined actions do.
Understanding Game Theory
The tragedy of the commons is also a topic in game theory. This is a field of study that looks at how people make decisions. It explores how individual choices affect a group, especially when people act in their own best interest.
