Importance of Biodiversity: Biodiversity provides food for humans for example some vegetable plants, fruits, etc. A significant proportion of drugs are derived, directly or indirectly, from biological sources. For example some anti-cancerous drugs are obtained from Taxus bacata . A wide range of industrial materials e.g. building materials, fibers, dyes, resins, gums, adhesives, rubber and oil are derived directly from plants.
Biodiversity plays important role in making and maintaining ecosystems. It plays a part in regulating the chemistry of our atmosphere and water supply. Biodiversity is directly involved in recycling nutrients and providing fertile soils.
