Earth Is Losing its Roots

What role do plant roots play in combating climate change?

• They prevent the growth of other plants.

• They increase the temperature of the soil.

• They store carbon in the soil, reducing atmospheric CO2.

• They release carbon dioxide into the atmosphere.

How does agriculture affect the distribution of root systems globally?

• It leads to a higher proportion of shallow-rooted plants.

• It has no impact on root systems.

• It increases the number of deep-rooted plants.

• It causes roots to grow deeper.

What is woody encroachment?

• The spread of shallow-rooted plants into forests.

• The expansion of woody plants into new areas.

• The reduction of forested areas.

• The increase in agricultural land.

Which regions are most affected by root loss due to land use changes?

• North America and Europe

• Central America and the Caribbean

• South America and Antarctica

• North Africa, the Middle East, Asia, and Australia

What is a suggested method to help reverse the trend of root loss?

• Encouraging the use of fossil fuels

• Increasing the amount of land used for agriculture

• Reducing meat consumption

• Decreasing the number of trees planted

Why is it more energy-efficient to eat crops directly rather than consuming meat?

• Meat provides more nutrients than crops.

• Energy is lost as it moves up the food chain.

• Crops require more energy to grow than animals.

• Animals produce more energy than crops.

How can reforestation help in addressing root loss?

• By increasing the number of shallow-rooted plants

• By decreasing the carbon content in the soil

• By reducing the need for agricultural land

• By restoring deep-rooted trees
