Though we may seldom realize it, our health is heavily dependent on biodiversity, which sustains
our food supply, is a source of nutrients and medicines, and support the provision of clean air
and fresh water, while also contributing to economic development, cultural and spiritual
enrichment.

Fast Facts

•        Palittaxel, used in treating breast, ovarian, and other cancers comes from the Paci c Yew
tree (taxus brevifolia).

•        Each year at least three million children under the age of five die due to environment-
related diseases.

•        Schistosomiasis, a parastic disease affecting over 200 million people annually, is carried
by freshwater snails. Over fishing may reduce populations of snail predators, resulting in a
greater risk of humas schistosomiasis. Deforestation in the tropics tends to favor snails that
carry schistosomiasis and mosquitoes that carry malaria.

proportion of their drinking water supply(Running Pure: The importance of forest protected
areas to drinking water, 2003 by Nigel Dudley and Sue stilton (Eds). A research report for the
World Bank/ WWF Alliance for Forest Conservation and Sustainable Use.)
