1) rubbish disposal - to make the area greener and greener we must not throw fruit or candy peels on the floor, we can put them in a package and then throw them in an urn
2) in order not to pollute the air more people have to ride a bike, walk or take public transport, because if all people have personal cars the air will be very polluted
3) I have a good enough idea to stop pollution and make the world greener and cleaner, if people want clean air, they must also follow some ecological rules. I think more garbage cans should be put up and they should be cleaned in public places.
