Question 44
This project is about how people develop and use scientific understanding, and how the uses of science can have a global environmental impact.
Work in a group of three or four.
You are going to investigate how a new or invasive species has affected an ecosystem.
Use the internet to find an example of a species that has been introduced into an ecosystem in your country.
Try to answer some of these questions.
- Where does the species normally live?
- Why and when was the new species introduced to your country?
- How has it affected the ecosystems it has been introduced to?
- Is it an invasive species? If so, why is it invasive in your country, but not its native country?
- Why did people not realise that the species might be a problem, when it was first introduced? How has understanding improved over time?
- Are people trying to eradicate or control the species? If so, how are they doing this, and how successful are they? Is everyone happy about this, or do some people want to protect the species?
Make a presentation about your findings, and be ready to share with others.
