Maintain
Biodiversity?
- Ecological
- Interdependence
- Ecosystems
are complex
- Food web - Evolved
to live together
- The balance can be upset by
external influence, causing
reduction in biodiversity
- Food web - Evolved
to live together
- More diverse, more stable (so less
effect if one species is reduced)
- Keystone species have a
disproportionate effect on a habitat,
greater than it might seem
- E.G. Beaver

- Genetic
resources
- Genetic diversity needs
maintaining within a habitat
- Could be a solution to a

- Living biosphere
affects landscape
- Trees protect soil
from erosion
- Run off and drainage are
reduced - acts as reservoir
for some time after
- Flooding is more likely
without trees, which is then
followed by drought
because of no reservoir

- Trees protect soil

- Summary
- Biodiversity is important to
maintain because otherwise it
could have cataclysmic effects
on humankind and the planet.
Without it, the economy suffers,
happiness decreases, species
will become extinct
