Industrial waste and agricultural run-off introduce metal such as copper and lead into waterways. These metals can contaminate soils and create serious health problems for humans and animals.
However, it is now being shown that banana peels can effectively pull contamination from the water. The study is showing a lot of promise and competition for for other chemicals that are out there to clean water.
When I read about this it really was clear that there are so many solutions out in the world that can help our dependence on chemicals and items that may cause more sustainability problems than they are worth. From this step I think the next step to take is making sure run-off is at a minimum and waste is taken care of in proper ways.
