Biodiversity, our scientists tell us, is a measure of the health of an ecosystem. The greater the genetic diversity, species diversity, and habitat diversity in a landscape, the greater the resilience of that landscape to disturbances such as pollution, invasive species, etc.

But at the same time, for multiple reasons, there has been a constant loss of species. Speaking on the World Wildlife Day on the topic of 'The Great Extinction: The state of biodiversity (India and the world)', Zoological Survey of India Director Dhriti Banerjee brought out the impact of the changing climatic conditions and the loss of species.
