Real-world.
- 1 Tropical rainforests have the highest terrestrial biodiversity, housing over 50% of all known species on just 6% of Earth's land
- 2 Coral reefs are called the 'rainforests of the sea' because of their extraordinary marine biodiversity
- 3 The loss of pollinator species threatens food crop biodiversity and agricultural productivity worldwide
