People should not litter.

When people litter they cause polution that kills animals. For excample when you shuck out a six can holder or a can fishes swim into it thinking that it is a home then they suffercate and die. Also when you litter it makes the fresh air bad and does critical damage to our lungs causing cancer eg, lung cancer ,heart problems,suffercation. That gives our healthly lives a chance to die. So when you can't find a bin put it in your pocket and when you see a bin put all your rubbish in there so you save a lot of lives.
