Tragedy of the Commons Part 1 - Chalk Talk

The tragedy of the commons occurs when individuals overuse a shared resource, leading to its depletion. This concept is illustrated through a pasture shared by farmers, where each adds more cows, harming the pasture. Real-world examples include depleted fish stocks and empty aquifers. Researchers study these interactions to find solutions, which are crucial as the global population grows and resources remain limited.

What is the main reason the farmers continue to add more cows to the pasture?

• They are unaware of the consequences.

• They are driven by self-interest to gain more milk.

• They believe the grass will grow faster.

• They want to help each other.

Which of the following is NOT an example of the tragedy of the commons?

• Depletion of aquifers.

• Traffic congestion on roads.

• Overfishing of Atlantic cod.

• A family sharing a private garden.

What happens to aquifers when water is withdrawn too quickly?

• They become polluted.

• They expand in size.

• They replenish faster.

• They start to empty.

Why is it important to study interactions between people and their environments?

• To find ways to protect shared resources.

• To encourage more individual ownership.

• To increase the number of shared resources.

• To reduce the global population.

As the global population grows, what remains constant, increasing the risk of tragedy?

• The amount of available resources.

• The space available for use.

• The rate of resource replenishment.

• The number of people using resources.
