Deforestation and Its Impacts

The video explains deforestation, its causes, and its global and local impacts on the environment and climate. It highlights the role of trees in carbon cycling and how their removal contributes to global warming. Locally, deforestation affects albedo and precipitation patterns. The video suggests solutions like selective logging and conservation, and encourages personal actions like reducing, reusing, and recycling to mitigate deforestation's effects.

What is deforestation?

• The process of creating urban parks

• The process of conserving forests

• The process of removing trees and forests from a landscape

• The process of planting trees in a barren land

Why is deforestation carried out?

• To increase forest cover

• To make way for other land uses such as agriculture

• To promote wildlife habitats

• To reduce carbon dioxide levels

How many football fields worth of forests are cut down every minute?

• 50

• 10

• 20

• 36

What percentage of Earth's land surface is covered by forests?

• 25%

• 10%

• 50%

• 75%

What do trees absorb and release during photosynthesis?

• Absorb oxygen and release nitrogen

• Absorb nitrogen and release oxygen

• Absorb carbon dioxide and release oxygen

• Absorb oxygen and release carbon dioxide

What is the effect of carbon dioxide acting as a greenhouse gas?

• It cools the Earth's surface

• It has no effect on the Earth's temperature

• It contributes to global warming

• It reduces the amount of sunlight reaching the Earth

What is albedo?

• The amount of water absorbed by a surface

• The amount of light reflected off a surface

• The amount of heat emitted by a surface

• The amount of light absorbed by a surface

How does deforestation affect local precipitation patterns?

• It causes more frequent storms

• It disrupts the water cycle, reducing rainfall

• It increases the amount of rainfall

• It has no effect on rainfall

What is one way to reduce the impact of deforestation?

• Burning forest materials

• Selective harvesting of trees

• Ignoring the problem

• Cutting down all trees in an area

What does the 'reduce' in the three Rs stand for?

• Using something again

• Disposing of waste properly

• Using less of something

• Planting more trees
