Importance of Biodiversity

The document discusses the importance of biodiversity. It defines biodiversity as the differences among living things in an ecosystem. Biodiversity increases ecosystem stability and provides more genetic variation among species. It is important for maintaining stable ecosystems, as greater diversity increases the chances that some species will survive environmental changes. Biodiversity is also necessary for its benefits to medicine, food, and industrial products. However, human activities like pollution, habitat destruction, and overharvesting can negatively impact biodiversity and lead to loss of species.

Biodiversity
As a result of
evolutionary
processes, there is a
variety of organisms
and a variety of roles
in ecosystems.

Biodiversity
Biodiversity-differences among
living things in an ecosystem.
Increased biodiversity increases
the stability of the ecosystem
It provides for more genetic
variation among species.

WhyisBiodiversitynecessary?
*To maintain stable ecosystems.
* A sudden change in the
balance of a communitys
environment may cause it to
be destroyed.
*A great diversity of species
increases the chance that at
least some living things will
survive with large
environmental changes.

Human Influences on Biodiversity

Human activities can,


deliberately or accidentally,
change the equilibrium in
ecosystems.

Human Influences lead to loss of


Biodiversity
-Cloning (decrease genetic material)
-Pollution
-Habitat Destruction (Deforestation)
-Land Use (overgrazing, building)
-Direct Harvesting (species removal)
-Imported Species (can be pests)
