Biodiversity
Genetic Diversity
the variation of genes within the same species
Ecosystem Diversity
the range of physical shapes and sizes of habitats, and the communities in an ecosystem
to the number and variety of species and ecosystems on earth.
Species Diversity
The variety of species within an ecosystem.
the health of an ecosystem
Why is it important?
Economic Reasons
Lumber, fishery catches, agriculture, livestock, recreation
Medicine
much of our ability to fight diseases and infections (and to find new cures) comes from organisms found all over the world.
Nature’s Service to Humans and ecosystems
Clean water, clean air, sources of food, soil for agriculture, pollinating effect of many insects, etc.
