Answer:

• We need the rain forests to produce oxygen and clean the atmosphere to help us breathe. We also know that the earth's climate can be affected, as well as the water cycle. Rainforests also provide us with many valuable medicinal plants, and may be a source of a cure from some deadly diseases.

• Coral reefs provide an important ecosystem for life underwater, protect coastal areas by reducing the power of waves hitting the coast, and provide a crucial source of income for millions of people.

• Mangroves provide valuable protection for communities at risk from sea-level rises and severe weather events caused by climate change. Coastal forests help the fight against global warming by removing carbon dioxide from the atmosphere, most of which is stored within the plant

• Together the coral reef and mangrove ecosystems form a barrier that protects shorelines from the destructive forces of wind, waves and driven debris. These living structures decrease the erosion and physical damage that can often impose significant economic and environmental costs on coastal communities.
