 The greater the society population and material wealth, the greater the amount and variety of its garbage and even the solid waste. So developed countries of the late 20th century are increasingly discovering that their material wealth and technological achievements are submerging them in a volume and variety of waste, solid and liquid, harmless and toxic, that threaten both their environments and their established way of life. In North America, it produces rubbish and garbage at a state of 200 million tons per year or about 1.6 kg per person per day. So this is actually the tragedy of the developed world and also is the tragedy of the developing world where industrial establishment is growing with the passage of time. China, we see that its industrial revolution in today's recent world, that country is producing maximum amount of solid and liquid waste. Next issue and problem of the urban place is the urban diseases. So is one of the examples of the urban place that here we have a word map dengue risk area which belongs to 2007, in which all its geological extension is, we see that between 2000 and 2007, how the dengue prevailed in the urban area and it belongs to the area which has high amount of precipitation in the air, i.e. where there is a lot of rain and water is present on the surface in the form of, we see that the liquid dumps are there, the waste is there, so those are the areas which are the hatcheries of the dengue virus. So in urban places, the construction that took place, the green spaces or the open space area was finished and the built up area changed there, so now the mosquitos that were in the open space earlier, they have shifted in the built up area or they are present there, so that's why it has human disease, maximum area which is under the built up region, there are human settlements, so that's why dengue is one of the urban disease of the decent world, so it is due to the water pollution and the risk areas of the world are the areas where we have more rainfall, where there is more moisture in the air and there is more surface water or there is more green cover, so this is one of the urban disease of the decent world and it mostly is one of the issue and problem of the urban area. Now ocean dumping is one of the issue of the urbanized world, in which we see that toxic waste material dumped into the ocean include dredging material, industrial waste, sewage, sludge and radioactive waste, so the coastal environment, today we have 60% of the total urban population is living closer to the coastal land, that is, 60% of the total urban population is living closer to the coastal land, so the dumps are deposited in the ocean, where dredging material is, dredging material is that we pick up the waste from the canal or from the liquid or solid and throw it into the ocean, so next we have industrial waste, sewage sludge, radioactive waste that we dump in the oceans, so that is actually one of the issue of the closer environment which is actually the neighbour of the urban place and also when we see this very big water body that we call oceans, when we contaminate it, its impact is on the closer environment or on the global environment, it can be local, regional and global as well, so this is one of the issue of the urban society. Dredging contribute about 80% of all waste dumped into the ocean, adding up to several million tons of material dumped each year, so we see that the impact of urban world is also on the ocean.
