Deforestation and Environmental Impact Quiz

What vital environmental role do forests play according to the video?

• They cool down cities directly

• They act as carbon sinks, absorbing CO₂

• They produce fossil fuels naturally

• They reflect sunlight back into space

What is the primary driver of deforestation shown in the video?

• Urban sprawl

• Logging for timber exports only

• Agricultural expansion (e.g., soy, cattle, palm oil)

• Construction of highways

How is deforestation shown progressing in satellite imagery in the video?

• As small, random patches

• Like lightning bolts from cities

• Like a contagion spreading across landscapes

• In a circular pattern from rivers

What is one major climate impact of cutting down forests mentioned in the video (besides CO₂ release)?

• Increase in Earth’s albedo

• B cycles

• Creation of desert wind tunnels

• Reflection of methane from the soil

Approximately what percentage of global carbon emissions is absorbed by forests each year?

• 10%

• 20%

• Around 30%

• 50%

According to the video, what happens to the soil after deforestation?

• It becomes enriched with new minerals

• It rapidly regenerates nutrients

• It erodes and loses fertility quickly

• It stores more carbon

What is a visible outcome of deforestation as captured by satellite in the video?

• Increased snowfall

• A patchwork of bare land replacing green forest

• Dense cloud buildup

• More animal migration into cities

What does the video imply about the speed of deforestation in some regions?

• It has been declining rapidly

• It occurs slowly over centuries

• It can happen rapidly and intensify once it begins

• It is balanced out by reforestation

Why is deforestation particularly dangerous in tropical regions like the Amazon?

• These regions don’t have much carbon

• They are already deserts

• Tropical forests store massive amounts of carbon and regulate rainfall

• They don’t regrow after being cut

What emotional tone is used in the video to highlight the deforestation crisis?

• Indifference and neutrality

• Hopeful and humorous

• Urgent and tragic

• Celebratory and optimistic
