The most diverse ecosystem in the world is the tropical rainforest. These ecosystems, found near the equator, are home to an astonishing variety of plant and animal species. Tropical rainforests boast multilayered canopies, rich biodiversity, and complex ecological interactions. They cover only about 6% of the Earth's surface but contain over half of the planet's terrestrial species, including countless insects, birds, mammals, reptiles, and plants. The combination of warm temperatures, high humidity, and abundant rainfall fosters this diversity, making tropical rainforests essential for ecological balance, global climate regulation, and conservation efforts.
