What on Earth is biodiversity?!

Biodiversity is a term used to describe the enormous variety of life on Earth. 

 

It includes every living thing, including plants, bacteria, animals, and humans. Scientists have estimated that there are around 8.7 million species of plants and animals in existence.

Much of the Earth’s biodiversity, however, is threatened. Pollution, climate change, and population growth are all threats to biodiversity. These threats have caused a big rise in the rate of extinction. 

 

Conservation efforts are necessary to preserve biodiversity and protect endangered species and their habitats.
