What did Thomas Malthus theorize about Earth's carrying capacity?

• Earth has a limit to supporting human population growth.

• Human population decreases naturally over time.

• Earth can support unlimited human growth.

• Technology will prevent any limits on population growth.

What role does technology play in addressing the limits of Earth's carrying capacity?

• It reduces human population growth

• It helps expand food production

• It decreases Earth's carrying capacity

• It has no significant impact

What is a direct consequence of human population growth on biodiversity?

• Improved quality of ecosystems

• Loss of species-rich habitats

• Decreased use of natural resources

• Increased species richness

How does land use change affect biodiversity?

• Increases habitat for wildlife

• Leads to habitat destruction and conversion

• Reduces pollution levels

• Enhances species richness

Which factor is NOT listed as a cause of biodiversity loss?

• Pollution

• Resource exploitation

• Introduction of native species

• Land use changes
