Biodiversity
• UNEP 1995 defined the biodiversity as :
“The variability among living organisms from all sources,
including terrestrial, marine and other aquatic ecosystems
and the ecological complexes of which they are apart; this
includes diversity within species, between species and of
ecosystems.” ( 2)

Biodiversity hotspot
( 4)
• A biodiversity hotspot is a biogeographic region
that is both a significant reservoir of biodiversity
and is threatened with destruction.
Refers to 25 biologically rich areas around the world that
have lost at least 70 percent of their original habitat.
Biodiversity hotspots amounts to just 1.4 percent of
the land surface of the planet, yet supports nearly 60
percent of the world's plant, bird, mammal, reptile,
and amphibian species..

• Loss of biodiversity refers to predicted changes
to the Earth caused by climate change and
human activities.
5 to 30 million species of animals and plants
– all genetically unique
About 1.4 million animal species have been
catalogued and named. There are only about 400,000
named and catalogued plant species.
Most remain unidentified.

Copenhagen
(8)
Four essentials calling for an international agreement in
Copenhagen are:
1. How much are the industrialized countries willing to reduce their
emissions of greenhouse gases?
2. How much are major developing countries such as China and India
willing to do to limit the growth of their emissions?
3. How is the help needed by developing countries to engage in reducing
their emissions and adapting to the impacts of climate change going to be
financed?
4. How is that money going to be managed?
