Environmental Problems In Urban Environment

The increase in urban population and the formation of large cities - megacities make environmental urban areas are at risk of severe recession. Clean water supply, housing, trees do not meet the population growth. Environmental pollution of air, water environment increased. Social evils and management issues in urban society increasingly difficult.
Population growth is putting heavy pressure on the global environment. The area of the earth virtually unchanged but the population increased many times. Rapid population growth makes the environment does not meet the basic needs of human beings. Want to survive, people had to deforestation to expand the area under cultivation and animal husbandry. Since 1950 - 1993, the cultivated area per capita

In 1999, the urban population in the world is 2.8 billion people, more than 4 times that of 1950. Currently, there are up to half the world's population live in urban areas, environmental challenges originate part of the municipality. Major cities have produced 75% of global CO2 as use of fossil fuels and consume 3/4 of the world's industrial wood. The speed of urbanization, environmental issues such as air and water pollution is worse in areas where the government is not capable of building and managing infrastructure for transportation, and processing of water trash. Currently there are 220 million people in the cities of the developing country in a state of lack of clean water and 1.1 billion people are living in an atmosphere of stifling pollution. Besides, the quality of soil also decreased markedly, land and bare hills occupy 30% of the natural area. Domestic sewage and industrial wastewater contaminated environments especially in cities and towns. The amount of waste increases with the increase in

Each year, the world population increases with a dizzying rate, the population growth will require more living space, more jobs, food, health and education. Whether in any aspect, the population explosion will create a huge burden on the environment. First, on the issue of accommodation, with the population growing rapidly increasing, the population density of the area and the human rising exploited jungle areas to create more space for the survival God. Thousands of hectares of forests are cut down to serve the industry, hundreds of forests were burned to make way for the construction of high-end residential areas, hotels, golf courses, parks and hundreds of production type of construction different building. Jungle Speed destruction took place too quickly, while the pace of recovery and growth of trees not outline any possible way unmatched. For example, a normal tree takes at least ten to twenty years to grow into a mature tree. Meanwhile, people only take a few minutes to cut down a tall tree a dozen years old. Land was burned causing the trees take a long time to be able to grow again, that is not to mention the land affected by acidity, salinity and lead contamination due to environmental pollution. Today, seeing a monkey hanging from a tree branch between a piece of land barren desolation is no longer strange to people. The forests are being destroyed to meet the needs
