I believe that cleanliness in the city, of course, a lot done. Every morning, go to work janitors, sweeps streets, courtyards, gardens and parks. Then take out garbage waste each container, with each entrance. Can you imagine what would happen if it all did? The city would simply drowned in the fallen leaves, bottles, wrappers, broken things and cleaning the kitchen!
But if everyone stops throw cigarette butts on the pavement, throwing on lawns empty packaging, "hide" in the bushes, plastic bottles, the city will be clean. As if by magic! But every citizen should do. No need to nod at each other and say, "Why me? Let neighbor takes care of cleanliness! ". We need to make their own rule cleanliness not only at home but also in the city. Cleanliness of our city depends on each of conscience of its inhabitants.
I think if every citizen to think about the environment, there will be in the trash. And not only the center of the city and even neighborhood will be clean. And also be able to solve other environmental problems of the city. For example, will decrease smoke from factory chimneys and car exhausts that pollute the air in the city. Or poisoned water from plants and factories that spoil the water in the rivers and springs of our city. The main thing - do not wake indifferent and do what we can.
