No one notices litter. Tourism is an important part of Pennsylvania's economy. People come from all over the world to see the beauty of our countryside, towns and cities. When litter mars their enjoyment, Pennsylvania loses valuable tourist dollars. Litter doesn't hurt anyone.
Litter is a breeding ground for rats and disease causing bacteria.
Litter doesn't affect the economy. Stores and businesses will not locate in a community which lacks the pride to effectively control litter.
