Investigating Earth's Natural Resources: Natural Resource Problems

The video discusses the importance of clean natural resources and the impact of pollution, which contaminates these resources and harms living organisms. It highlights how pollution from fossil fuels affects the environment and society's concern over this issue. The video also covers the concept of overconsumption, using a reservoir as an example, and explains how excessive use of resources leads to scarcity, as seen in overfishing.

What is one of the main effects of pollution on the Earth's atmosphere?

• It negatively affects the chemistry of the atmosphere.

• It enhances plant growth.

• It reduces the amount of sunlight reaching the Earth.

• It increases the oxygen levels.

What happens to a reservoir if water is used faster than it can be replenished?

• It eventually dries up.

• It turns into a freshwater lake.

• It becomes a natural habitat for fish.

• It increases in volume.

What is a consequence of overconsumption of natural resources?

• Resources become more diverse.

• Resources become renewable.

• Resources become scarce.

• Resources become more abundant.

Which of the following is an example of resource scarcity due to overconsumption?

• Abundant water supply

• Overfishing leading to fewer fish

• Increased forestation

• Increased mineral deposits

How does overfishing affect ocean ecosystems?

• It enhances coral reef growth.

• It increases the number of fish species.

• It leads to a scarcity of certain fish species.

• It improves water quality.
