Bio diversity

Biodiversity is the variation of life forms within a given ecosystem, such as an entire planet or even a small lake. The number of species of plants, animals, and microorganisms, the enormous diversity of genes in these species, the different ecosystems on the planet, such as deserts, rainforests and coral reefs are all part of a biologically diverse Earth. Biodiversity is often a measure of the health of an ecosystem. It is also a function of climate: in warmer regions, there are many different species, where colder polar regions support much fewer species. Environmental changes, such as global warming or climate change, can lead to extinctions. Since the arrival of humans, biodiversity has been decreasing. Biodiversity is important because it boosts ecosystem productivity. The years 2011-2020 are known as the United Nations Decade on Biodiversity.
