Where is the majority of the Earth's biodiversity primarily located?

The majority of the Earth's biodiversity is primarily located in the tropics. This region, which includes areas near the equator, is characterized by warm temperatures and high rainfall, creating ideal conditions for a vast array of plant and animal species to thrive. The tropics support complex ecosystems, such as tropical rainforests and coral reefs, known for their incredible variety and high levels of species richness.

The abundance of biodiversity in the tropics can be attributed to the stable climate, which allows many species to evolve and coexist over long periods. These ecosystems often serve as habitats for numerous unique species that are found nowhere else on Earth. Consequently, the tropical regions are essential for global biodiversity and play a crucial role in maintaining ecological balance.

In contrast, temperate regions, biodiversity hotspots, and polar regions each have lower biodiversity levels due to various environmental factors such as climate variations, habitat types, and geographical constraints that limit species diversity compared to the tropical areas.
