Text 2. The main causes which endanger biodiversity of islands
- Colonization of formerly uninhabited islands and unsustainable use of flora and fauna
- Domestic types of animals like dogs, cats, rats, pigs or weasels which are dominating the endemic types of animals on an island
- Non-resident species that are brought in
- Deforestation of mangroves and thus an increase of delicateness of storms and floods
- Ascent of the sea level and increase of frequency or intensity of extreme events (storms, heavy rain) by climate change
- Increase of sea temperature by climate change, which coral reefs are non-conformist
- Garbage which is washed ashore by the sea and which could be swallowed by animals or in which they could become entangled (nets)
- Overfishing of offshore stretch of water
