Carbon Sequestration and Climate Change

The video explains the carbon cycle, highlighting how humans and plants exchange carbon dioxide and oxygen. It discusses the negative impact of burning fossil fuels, which releases excess carbon dioxide into the atmosphere, contributing to climate change. The concept of carbon sequestration is introduced, emphasizing the role of trees in capturing and storing carbon. Sustainable forestry practices are suggested as a solution to manage carbon levels effectively. The video concludes by stressing the importance of these practices in combating climate change and ensuring a healthy future for the planet.

What process do plants use to convert carbon dioxide into oxygen?

• Fermentation

• Respiration

• Photosynthesis

• Transpiration

Why is carbon dioxide considered a greenhouse gas?

• It cools the Earth's surface.

• It absorbs sunlight directly.

• It reflects sunlight back into space.

• It traps heat in the atmosphere.

What has caused the exponential increase in carbon dioxide emissions since the industrial revolution?

• Increased volcanic activity

• Deforestation

• Burning of fossil fuels

• Natural carbon cycle

Which of the following is a method to actively capture and store excess carbon dioxide?

• Carbon sequestration

• Carbon reduction

• Carbon emission

• Carbon oxidation

What is the primary benefit of planting young, fast-growing trees?

• They sequester more carbon.

• They provide more shade.

• They grow in any climate.

• They require less water.

What happens to carbon when old trees die and rot in the forest?

• It is permanently stored.

• It becomes fossil fuel.

• It is released back into the atmosphere.

• It turns into oxygen.

What is the term for managing forests to ensure continuous carbon sequestration?

• Afforestation

• Reforestation

• Sustainable forestry

• Deforestation

Which type of forests play the largest role in carbon sequestration in America?

• National parks

• Urban forests

• Private working forests

• Rainforests

What percentage of carbon sequestration in America's forests is accounted for by private working forests?

• 90%

• 75%

• 60%

• 50%

Why is carbon sequestration important in the fight against climate change?

• It decreases oxygen levels.

• It increases global temperatures.

• It reduces the amount of carbon in the atmosphere.

• It accelerates the melting of glaciers.
