how does biodiversity contribute to medicinal needs?

most medications derived from living organisms. based on biodiversity in the tropical rainforest an additional 328 types of drugs are yet to be found

wild plants act as gene pools for those plants used in agriculture. they have the potential to increase resistance to viruses, faster growth, etc.

how does biodiversity contribute to consumptive needs?

new products such as nuts and fruits, new chemicals, etc.

how does biodiversity contribute to natural community needs?

control air pollution, prevent soil erosion, clean polluted water, provide recreational value
