Environmental changes like increased temperature can stress an ecosystem. Why is this an issue with regard to invasive species?
1. Ecosystems are destroyed by environmental changes, and then invasive species establish a new ecosystem, so the original organisms can never reintegrate.
2. Invasive species are more easy to introduce to a stressed ecosystem.
3. Invasive species thrive in stressed ecosystems like those with warmer temperatures.
4. Ecosystems are unable to recover as quickly from damage due to invasive species and environmental changes.
