How to use biodiversity

Biodiversity is used primarily in scientific, environmental, and policy contexts to refer to the variety of life at multiple levels—species, genetic, and ecosystem. It is a technical term that has become common in discussions of climate change, environmental protection, and sustainability. Unlike casual synonyms like 'variety', biodiversity carries specific scientific weight.

A common mistake
