Littering is not very good,because things like bottle caps,broken glass pieces,plastic or even brick can hurt many different animals.They can get a cut from glass,get thier heads stuck in bottles[which can also cause suffocation],eat pieces of plastic and get germs from licking,tasting and smelling brick,since all the dust and dirty particals will go through.If you have littered before[either by accident or by purpose],make sure you never,ever do it again.
