Rainforests for Kids

Rainforests are vital ecosystems covering 6% of Earth's surface, housing over half of the world's plant and animal species. They play a crucial role in photosynthesis, producing 40% of atmospheric oxygen and absorbing carbon dioxide, thus mitigating global warming. Rainforests are structured in four layers: emergent, canopy, understory, and forest floor, each hosting unique flora and fauna. Despite nutrient-poor soil, efficient recycling by decomposers sustains these ecosystems. Rainforests are essential for global climate regulation, water cycles, and provide resources for medicines. Conservation is critical due to threats from human activities and climate change.
