Biodiversity is simply known as a variety of life forms within the ecosystem. It is very important because it enhances the ecosystem resilience to climate change, thereby providing stability to the natural world, via the divesity of species and genetic ressources. These are really able to face climate change negative impacts
Biodiversity can be regarded as an 'insurance policy' for ecological functioning. If there are more species in an ecosystem, there are more likely to be among those species those that can deal with new pressures and challenges that arise when the ecosystem is changing over time. Because climate change probably leads to a speeding op of ecosystem change in many different ecosystems, it is good to have a reserve of species that may take over processes such a biomass production, nutrient cycling, water retention etc. in any ecosystem to prevent total collapse of that ecosystem.
