1. The important roles of tropical rainforests in the earth's environment: Rainforests are often called the lungs of the planet for their role in absorbing carbon dioxide, a greenhouse gas, and increasing local humidity.

2. If all trees were cut down and burned, the forest's carbon storage capacity would be lost to the atmosphere.

3. The most common pressures causing deforestation and severe forest degradation are agriculture, unsustainable forest management, mining, infrastructure projects and increased fire incidence and intensity.

4. Need to conserve and protect tropical rainforests: The most important function of forests is that it produces mass amounts of oxygen as a by-product of photosynthesis. ... Forests also prevent soil erosion and keep soil pollution in check.

5. If coral reefs are destroyed: Sea life has the most to lose. Coral reefs cover less than 1% of the ocean floor. But, they provide an essential ecosystem for a quarter of all marine life.

6. Pollution, overfishing, destructive fishing practices using dynamite or cyanide, collecting live corals for the aquarium market, mining coral for building materials, and a warming climate are some of the many ways that people damage reefs all around the world every day.
