Having a clean and Eco friendly city is just a fragment. There are many forms of pollution: air pollution, water pollution, light pollution, soil contamination, light pollution etc. A few ways of helping reduce pollution would be: the most obvious is recycling, you just have to sort out your trash, and throw it in special recycling containers, it's that easy, another way is preventing, just don't trow plastic bags, empty soda cans, and other things on the ground or in water, but that's a bit hard to do since most people enjoying acting like apes (that's a bit of insult to them, since they don't do half the things that mankind does). I'm going to suggest joining an environmental organizations or just volunteering to clean up after others, if you simply stop throwing trash on the ground or anywhere else it's enough for an average Joe.
