10 Most Biodiverse Countries in the World

What are the most biodiverse countries in the world? In today’s world, when plants and animals are disappearing faster than we’d like, it’s nice to see that some countries do their best to preserve the species they have in their territories, such as these 10 most biodiverse countries in the world.

What makes a country mega-diverse? Well, first of all, only a few countries in the world have enough biodiversity to rank this high. Biodiversity as a term includes all of the plant and animal species on the planet, with genetic differences, as well as the ecosystems where they can be found. In order for a nation to be on the mega-diverse list, they need to have at least 5,000 endemic plants and to have a marine ecosystem within its borders. Conservation International notes there are only 17 countries that fit the bill, accounting for 70% of the world’s flora and fauna. At the same time, their territories put together comprise under 10% of the world’s territory.
