The biodiversity and species richness has almost exclusively positive effects in every aspect, lot of which are of huge importance and benefit for the humans.

- economic
- agricultural
- medicinal
- ecological
The economic benefits are seen in the fact that lot of species are very interesting and attractive to the people, so some sectors, such as the tourism directly depends on the biodiversity in lot of parts in the world. For the agriculture, it is good that the biodiversity is high, as that means that the pests will be naturally regulated by their predators. The medicine is directly dependent on the biodiversity, as it relies on lot of species to produce the medicines, and if they are gone, this industry will crumble. From ecological aspect, the biodiversity and species richness is important because the communities of organisms will remain as they are, function without any problems, and be in prefect balance.
