Biodiversity, short for biological diversity, is the variety of life on Earth – from the smallest microorganism to the biggest mammal. Biodiversity is called the “Web of Life” as it encompasses all species and their interaction among themselves and with their habitats which w ecall ecosystems. Biodiversity and ecosystems provide us with air, water and food; materials for clothing, medicine and shelter; livelihood; and a host of services that are basic to human survival. This “Web of Life”, however, is fast becoming endangered.
