As a group you will be divided in to four teams. Each team will be given an environmental impact of agriculture and water quality to research. As a team you will develop an information sheet on how agricultural methods can cause degradation of the quality of the water in freshwater channels.
Each sheet will need to include the following points:
- Definition of the environmental impact.
- Causes of the environmental impact - don't just say farming!
- Example - Where? How did it specifically happen? What has been the impact? Can the impact be managed? Data, data, data!!
