  • Study Notes

    Importance of Rainforests

    • Rainforests play a crucial role in maintaining the health of our planet by producing approximately 28% of the world's oxygen, supporting an enormous array of biodiversity, and providing habitat for indigenous communities.
    • They also serve as massive carbon sinks, absorbing and storing significant amounts of carbon dioxide, helping to mitigate climate change.

    Ecological Functions

    • Rainforests act as a giant pharmacy, providing numerous medicinal plants, with many modern medicines derived from their unique flora and fauna.
    • They are responsible for recycling nutrients, decomposing organic matter, and maintaining soil fertility, ensuring the long-term sustainability of ecosystems.

    Rainforests and the Global Water Cycle

    • Rainforests play a vital role in the global water cycle, with approximately 20% of the world's freshwater being cycled through these ecosystems.
    • They help regulate rainfall patterns, maintain river flow, and prevent droughts and floods by absorbing and storing water, which is then released into the atmosphere through a process called transpiration.
    • The Amazon rainforest alone produces about 20% of the world's oxygen and is responsible for 15% of the global freshwater supply.
