My Idea

One thing I think we should talk about is your environment and how it affects your health. We are lucky, because we live near Lake Erie. But there is also a lot of responsibility with having a large water system. We are also near the dividing line of two watersheds. Whatever we do to our lake here, affects two different areas where water flows. Some things we are doing to our water is putting pesticides or fertilzers in it. These chemicals cannot be taken out of the water. Another problem is silt and other kinds of particles that dissolve into the water. Some companies get rid of their waste into the lake, and some of these wastes contain mercury. These three aspects relate to your health because if you eat fish out of Lake Erie, those fish are contaminated with harmful substances. There are restrictions on how much fish you can consume from Lake Erie, because you cannot be exposed to high levels of mercury constantly. This is really affect your health.
