Yes it is pollution. And so is sewage, fishing line, cigarette butts, sandwich bags, candy wrappers, beverage bottles/cans, etc. We should all be good stewards of these great resources. We are all guilty of accidental pollution. Every time we break a line or something blows overboard, it's pollution. Granted there are different degrees of pollution, but it all adds up. Be good stewards and encourage others to be also. Pollution awareness has already made a noticeable difference. We can make a difference if we choose to. Keep a litter bag in your car, truck, or boat. The best way to teach is by example.
