- The Earth is populated by a rich and
diverse range of plant and animal species
- These species have evolved to inhabit
and exploit a huge range of environments.
- The Earth is in a constant process of
change
- New species are constantly evolving, and
others are dying out
- This extinction has been accelerated by
human actions
- Some of the lost species possess
irreplaceable properties - such as medicines, for example
- This process is not restricted to other
countries; species are also under threat in the UK.
