  1. EARTH CONSERVATION Pollution Due To Urbanization and its effects

  2. #1- Biodiversity As cities grow in number, spatial extent and density, their environmental and ecological footprints increase. Urban expansion that takes place in forests, wetlands and agricultural systems leads to habitat clearing; degradation and fragmentation of the landscapes.

  3. #2- Inequality Water Approximately 97% of the earth’s water is stored in the oceans, and only a fraction of the remaining portion is usable freshwater. When precipitation falls over the land, it follows various routes

  4. #3- Air Pollution Air pollution often plagues industrialized cities, particularly during their early development. Episodes of high levels of sulfurous smog killed or sickened thousands

  5. #4- Diseases Another urbanization-related threat is infectious diseases. Air travel carries bacteria and viruses from one country to the next. In addition, people relocating from rural areas are not immune to the same diseases as long-time city residents, which puts them at a greater risk of contracting a disease.

  6. #5- Elevated emissions of air pollutants and GHGs This is a consequence of urban industry, emissions from cars, and the electricity demand. Around the world, companies use fossil fuels such as coal and petrol to generate electricity. Burning these compounds leads to an increase in air pollutant

  7. #6- Development of slums The cost of living in urban areas is very high. When this is combined with random and unexpected growth as well as unemployment, there is the spread of unlawful resident settlements represented by slums and squatters

  8. #7-Threats • Intensive urban growth can lead to greater poverty, with local governments unable to provide services for all people. • Concentrated energy use leads to greater air pollution with significant impact on human health. • Automobile exhaust produces elevated lead levels in urban air.

  9. #8-solution • Combat poverty by promoting economic development and job creation. • Involve local community in local government. • Reduce air pollution by upgrading energy use and alternative transport systems.
