    Don’t let rubbish get into a stream. Whether it’s a stream in your backyard or you’re out on a walk, don’t litter! Even cigarettes and dog droppings are dangerous – they can add pathogens and other toxins to the water. Learn more about poo and water contamination in Sources of poo. (Note that E. coli, one of the harmful bacteria found in poo, is not harmful to fish like it is to humans.)
