Front

What is overharvesting?

Back

Overharvesting is the excessive removal of natural resources, such as fish or timber, at a rate faster than they can be replenished, threatening species and ecosystems.

Front

What are the effects of pollution on living organisms?

Back

Pollution can cause health problems in humans and animals, disrupt ecosystems, reduce biodiversity, and lead to the extinction of species.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere, which can be exacerbated by pollution.
