Ice
Ice
- Melting ice causes sea levels to rise, which could flood coastal habitats forever, losing the land and associated biodiversity.
- Changes to the way sea ice changes through the year is affecting the survival of animals at both poles.

Distribution of species
Distribution of species
- Malaria-carrying mosquitoes have already spread to several European countries.
- It is possible that malaria and similar exotic diseases will become an established part of life as far North as the UK in the near future.

Reduction of biodiversity
Reduction of biodiversity
- The rate at which the climate is changing makes rapid adaptation key to avoiding extinction.
- This is particularly challenging for large-bodied animals that typically have longer generation times.
Maintaining Biodiversity
Maintaining Biodiversity
Programmes have been established by scientists and governments that attempt to mitigate (soften) the negative impact of humans on ecosystems and biodiversity:

Incentivising farmers
Incentivising farmers
- Farmers are being incentivised to maintain field margins and hedgerows, as these habitats can support biodiversity.
