Learning objective
• Eutrophication can substantially impact ecosystem services • Eutrophication can affect services associated with fisheries, recreation, aesthetics and health
Start with the concept explanation, then practise to create mastery evidence.
Learning objective
• Eutrophication can be addressed at three different levels of management • These three levels of management are: • the reduction of human activities that produce pollutants—e.g., alternatives to current fertilizers and detergents • the reduction of the release of pollution into the environment—e.g., treatment of wastewater to remove nitrates and phosphates
