Ecosystem diversity
What benefits do we get from biodiversity?
BIODIVERSITY FEEDS THE WORLD
Biodiversity provides air and water
Biodiversity provides
materials for clothing and shelter
Biodiversity heals
Biodiversity brings income to millions
Biodiversity soothes
self sustaining collection of organisms and habitat
Ecosystem diversity
