When my family used to go to public places like temples,rivers,waterfalls,picnics,etc we all used to bring some food with us and then after eating food we used to throw it there or just leave it. One day I realised how much waste this could create if everyone's mentality was like this. So I took an initiative and started to bring back home the waste that we generate at any public place is there was no grabage bin around.I even implemented this strategy for the wrappers that gets created while travelling in car ,bus,train,etc. I don't even let people throw them.
