The Borneo rainforests are among the oldest rainforests in the world, estimated to be over 130 million years old. They cover much of the island of Borneo, which is shared by Malaysia, Indonesia, and Brunei. These forests are known for their incredible biodiversity, housing thousands of plant and animal species, many of which are unique to the region. The rainforests play a crucial role in the global ecosystem by absorbing carbon dioxide and producing oxygen. They are also vital for the local communities, providing resources such as food, medicine, and materials. However, these forests face significant threats from deforestation and illegal logging, impacting both wildlife and indigenous cultures.
