Colombia's biodiversity is one of the highest in the world. This is due to its geographical location, variety of climates, and diversity of ecosystems. Colombia hosts more than 10% of the world's biodiversity within its territory, despite occupying only 0.7% of the planet's land surface. Moreover, it is home to a large number of endemic species, meaning species that are not found anywhere else in the world.

One of the most remarkable aspects of Colombian biodiversity is the presence of multiple ecosystems ranging from tropical rainforests to Andean paramos. This variety of ecosystems allows for the coexistence of a great diversity of flora and fauna. However, Colombia's biodiversity faces threats due to human activities such as deforestation, illegal mining, and climate change.

To conserve this natural wealth, various conservation strategies have been implemented, including the creation of protected areas and the promotion of sustainable practices. Despite these efforts, the conservation of biodiversity remains a crucial challenge for Colombia and for the world in general.
