How are plastic bags and guns the same?

Wildwood - How are plastic bags and guns the same? Plastic bags don't through themselves on the ground or in nature. Guns don't get up by themselves and shoot people. People throw plastic bags. People pull triggers. How many laws do you need to make people responsible for their actions, 1 or 100? We, the people are destroying our planet and eachother. When is the time to be responsible?
