Impact of Deforestation on Ecosystems

The video discusses the necessity of cutting down trees for resources like wood and paper, while highlighting the negative impacts on ecosystems, such as deforestation, habitat loss, and climate change. It emphasizes the role of forests in oxygen production and greenhouse gas absorption, and the potential consequences of deforestation on global warming and biodiversity. The importance of tropical forests, like the Amazon, in maintaining climate balance is also covered.

What is one of the primary reasons for cutting down trees?

• To increase biodiversity

• To produce wood for construction

• To reduce air pollution

• To promote soil erosion

How does the destruction of trees potentially contribute to global warming?

• By increasing oxygen levels

• By absorbing more greenhouse gases

• By cooling the Earth's surface

• By reducing the absorption of greenhouse gases

What percentage of Earth's land animals and plants live in forests according to National Geographic?

• 50%

• 60%

• 70%

• 80%

What role do tropical forests like the Amazon play in the environment?

• They decrease rainfall

• They promote a cycle of evaporation and rainfall

• They increase desertification

• They reduce biodiversity

What could be a consequence of losing rainforests near the tropics?

• Warmer and drier climates

• Stable climate conditions

• Cooler and wetter climates

• Increased snowfall
