Rainforest Biodiversity
雨林生物多样性
Description
Understand that rainforests are biodiversity hotspots — covering just 6% of Earth's land surface but containing over 50% of all known plant and animal species — and that this extraordinary richness makes them irreplaceable for global biodiversity and a priority for conservation
Mastery Evidence
- State that rainforests cover about 6% of Earth's land but hold over 50% of all species
- Explain why this concentration of species makes rainforests a conservation priority
- Give specific examples of rainforest biodiversity, such as one hectare containing more tree species than all of northern Europe
Assessment Prompt
Can your child explain the mind-boggling fact that rainforests cover only a tiny fraction of Earth but are home to more than half of all species — and why that makes protecting them so important?
