Forests primarily provide ecosystem services related to timber production and carbon sequestration, with minimal impact on water purification.
Answer: False
Forests provide a wide array of critical ecosystem services, including significant contributions to water purification, flood and drought mitigation, soil erosion control, and disease reduction, in addition to carbon sequestration.
The World Health Organization emphasizes that forests contribute to disease reduction and erosion control, in addition to flood mitigation and water purification.
Answer: True
The World Health Organization indeed highlights forests' contributions to erosion control and disease reduction, complementing their established roles in flood mitigation and water purification, all vital for human well-being.
Tropical forests are vital for climate change mitigation because they are significant sources of atmospheric carbon dioxide.
Answer: False

Answer: True
Preserving the size, continuity, and biodiversity of forests is indeed crucial, as these attributes directly ensure the ongoing provision of essential ecosystem services that underpin human health and prosperity.
Which of the following is NOT listed as a critical ecosystem service provided by forests?
Answer: Generation of fossil fuels.
Forests provide numerous critical ecosystem services, including flood and drought mitigation, water purification, and soil erosion control. The generation of fossil fuels is not an ecosystem service provided by living forests.
What significant role do tropical forests play in mitigating climate change?
Answer: They function as large carbon sinks, absorbing atmospheric carbon dioxide.
Tropical forests play a critical role in climate change mitigation by acting as large carbon sinks, actively absorbing atmospheric carbon dioxide through photosynthesis and storing it in their biomass.

The annual rate of forest loss has indeed decreased, from 7.8 million hectares per year in the 1990s to 4.7 million hectares per year in the 2010s, reflecting a positive trend in forest conservation.
The slowdown in forest loss is primarily due to a global shift towards industrial agriculture, reducing the need for new forest land.
Answer: False
The slowdown in the rate of global forest loss is primarily attributed to the natural regeneration capabilities of forests and concerted global efforts to reduce deforestation, rather than a shift towards industrial agriculture.
Plantation forests are a new method of reforestation that emerged in the 21st century, focusing on monoculture for timber production.
