🌎 Human Impact and Ecosystem Degradation
This quiz explores how human activities degrade ecosystems and biodiversity across Canada and globally. You'll examine habitat destruction, pollution, overexploitation of resources, and climate change impacts. Learn about key environmental problems like eutrophication in the Great Lakes, acid rain, ozone depletion, and the greenhouse effect, and understand why protecting ecosystems matters. **What you'll learn:** - How habitat destruction, pollution, and overexploitation damage ecosystems - The causes and effects of eutrophication, acid rain, ozone depletion, and climate change - Canadian environmental challenges (Great Lakes, forests, marine ecosystems) - How biodiversity loss affects ecosystem health
