For centuries, man, as an important part of nature, has caused irreparable damage to its equilibrium. After the Second World War, it became clear that this process had led to the extinction of several species of animals. In spite of the importance of biodiversity, it only became an international, political concept after the Earth Summit in 1992. This was held in Rio de Janeiro, where the Agreement on Biodiversity was signed by many countries. Since then, biodiversity as a term has been widely used by politicians, the media, social organisations and others.
