Biodiversity on Earth

The video explores the characteristics of tropical rainforests and tundras, highlighting their differences in biodiversity. Tropical rainforests, located near the equator, are warm and moist, supporting at least 2 million species, with many yet to be discovered. In contrast, tundras are cold, dry, and have fewer species due to their harsh conditions. The video encourages viewers to consider the biodiversity in their own environments.
