Create a visual aid that illustrates a problem - Assignment Example The worst polluted cities Time Magazine has a listing of the world’s most polluted cities. Two are in China, two in India, two in Russia and a city each in Peru, Ukraine, Azerbaizan and Zambia. There are criteria set for categorizing the most polluted cities, and these are: the high volume of people, traffic congestion, trash and air pollution; mercury contaminated water and sewerage; danger to humans in contracting cancer by 50%, and danger to death by more than 50% compared with those not living in these cities. The most polluted cities show various types of pollutants, such as coal and particulates coming from automobiles and industrial plants. The city of Linfin in China, for example, is at the heart of China’s coal belt. Its air is filled with smog from burning coal; laundry on clotheslines turn black before it can dry under the sun. Sad to say, little is being done about the situation in these cities, especially as warnings on pollutants are muffled by talk on glo bal warming, the more dominant environmental topic today. But the problem of pollution in cities is most urgent since pollution is a direct threat to human health. Even the World Health Organization reports that water and air pollution cause GREENING THE CITIES 20% of global disease (Time). The greenest cities Fortunately solutions exist, and greening can start in cities where it is most critically needed. There are five cities recognized as the â€Å"Five Most Amazing Green Cities† by experts who used a combination of criteria including urban planning and environmental statistics (energy sources, consumption, emissions, transportation options, habits). Green cities show the availability of public parks, sustainable buildings, green jobs, and other ecological perspectives such as recycling (Howstuffworks). The first of the cities recognized for its green practices is Malmo, Sweden, with its canals, beaches, parks, and harbours looking as fresh as they were during the Middle A ges. Sweden itself leads in the green electricity revolution, while Malmo’s Western Harbour is run by 100% renewable energy sourced from the sun, wind, hydropower ad biofuels. Buildings and homes have green roofing, and are designed to be energy efficient. Streets are pedestrian and cycle friendly with 70% commuters and other travellers going on bike. The other four leading eco-cities are: (a) Copenhagen, Denmark, which has reduced cars for green transportation using bikes and a metro system. Its 56.000 windmills supply 10% of Denmark’s electricity comprising the world’s largest offshore windmill park. (b) Portland, Oregon, has 92,000 acres of green space and 74 miles of biking, hiking and running trails. Its ambitious goal is the use of 100% renewable energy by 2010. (c) Vancouver, Canada, was GREENING THE CITIES named â€Å"The World’s Most liveable City† by the Economist Magazine. It has a 100-year plan for clean and green living, and it leads t he world in the use of hydroelectric energy, while reducing wind, solar, wave and tidal energy. (d) Reykiovik, Ireland, is described as the smallest amazing green community with its 115,000 population, which is almost half of the 300,00 total population of Iceland. It uses hydrogen energy in addition to heat, geothermal and electricity energy sources. Turning the tide through greening is illustrated by a planned proposal for the capital city of Manila with its urban pollutants caused by heavy congestion of crude fuel-run motor vehicles, buildings without
