Tropical rainforests are often referred to as the "lungs of the planet" because they produce a significant amount of the world's oxygen while absorbing carbon dioxide. With their unending biodiversity, these ecosystems are home to more than half of the world's plant and animal species, showcasing an intricate web of life that has evolved over millions of years. In real-world applications, the preservation of tropical rainforests is crucial for combating climate change and protecting biodiversity. Many indigenous communities depend on these ecosystems for their livelihoods, using sustainable practices that work in harmony with nature. Efforts like ecotourism promote conservation while providing economic benefits, showing that protecting the environment can go hand-in-hand with human prosperity.
