Biodiversity is a resource with enormous potential, both for intellectual and economic purposes and as an instrument for a country’s development.
The tropical zones of the American continent (Neotropics), where Costa Rica is located, contain a greater diversity of species and ecosystems, as well as a broader range of interactions, compared with other tropical regions of the world. Obviously, this diversity is also much greater than that of temperate and cold regions. With a land area of only 51.100 km2 (0.03% of the planet’s surface) and 589.000 km2 of territorial waters, Costa Rica is considered to be one of the 20 countries with greatest biodiversity in the world.

Convention on Biological Diversity. But to be the first developing country in the world to meet its commitments to protect biodiversity, Costa Rica still has work to do.
