Exotic species can affect biodiversity by spreading seeds

Exotic species are often a threat to biodiversity, as they change the structure and functioning of natural ecosystems. For example, they change how seeds are spread. This can have a big impact as 90% of plants in tropical regions depend on animals to spread their seeds and 60% in non-tropical regions. They affect ecosystems by 1. Affecting native plant species 2. Affecting mutual dependencies 3. Affecting seed quality 4. Supporting habitat restoration Learn more about these 4 ways in which exotic species can harm ecosystems through seed dispersal:

We can prevent this from happening for example by:
- Refraining from bringing seeds when traveling
- Refraining from bringing exotic animals back home as pet
