Passage: 21
Rainforests are dense forests found in regions where there is heavy rainfall throughout the year. They are home to millions of plant and animal species. Rainforests help regulate the Earth’s climate by absorbing carbon dioxide and producing oxygen. They also play a crucial role in maintaining the water cycle by releasing water vapor into the atmosphere. However, these forests are under threat due to deforestation, illegal logging, and human activities. Protecting rainforests is essential for the survival of countless species and the health of our planet.
