Based on the protection of Colombian Biodiversity. Taking as a notorious fact that human beings, in carrying out their economic and cultural activities, have had a negative impact on the environment, causing several species to disappear and others to be on the verge of extinction (Andrade, 1992). The legal-political challenges of the Colombian Government to face these environmental problems are analyzed, as well as the legal tools currently available and whether they are sufficient.
