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.
Explanation:
The biodiversity and species richness is basically the amount of species that inhabit a particular ecosystem, while on global level it represents all of the species on the planet. The more species there are on the planet, the better, and vice versa, the less species there are, the worse. The reason for this is that pretty much every species provides some benefits, which are good both for nature and for the humans. The befits can be seen from several different aspects, such as:
- 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.
