After three industrial revolutions, human keeps on taking steps to develop modern technology, making themselves the dominant species on the Earth. However, there is a high price to pay since pollution has become one of the most serious problems we have to confront. The first factor that is under great strain is the source of water. In the modern times, a number of factories have been built, leading to a huge amount of waste that needs to be dealt with. But with a lack of sewage treatment systems, most of this is dumped directly into rivers or lakes, destroying marine life. In addition, oil spills from tanker ship accidents also contribute to water population, which killed thousands of seabirds and aquatic animals. Not only water, the air is also contaminated seriously. It is shown that most of the amount of carbon dioxide released into the atmosphere comes from coal burning power plants and motor vehicles, causing global warming and greenhouse effect. The situation became worse since our green lungs have been damaged seriously due to the alarming rate of deforestation. As a result of air pollution, human health can be threatened and put at risk of respiratory problems and hives.Last but not least, soil pollution is another example of our negative impacts on the environment. With modern farming practices and the abuse of chemical pesticides, the quality of soil is increasingly degraded on account of the loss of important minerals and microorganisms in it. Moreover, it can be polluted by improper disposal of waste or heavy metals from factories and power plants. These substances will enter the waterways and then our food chain, which gradually do harm to our health. In all likelihood, arable land will turn into desert or be lost to erosion and water logging. To conclude, the environment is polluted at a high rate, affecting our life negatively in many ways. Therefore, there is a need to take measures to save the Earth before it is too late.

Air pollution
Air pollution is now a serious problem for those living in my area. Air pollution may be any industrial
waste, gases, dust, fume or odour in harmful amounts which are harmful for human, vegetation, animals or buildings.
Air pollution can have some different causes. The major source of air pollution is industrial waste from factories. The second is exhaust from cars, motor vehicles and planes. Agricultural activities as crop spraying with pesticides and herbicides are another one.
Air pollution can have dramatic effects. It causes various dangerous diseases, death to human, damage to other living organisms such as animals and food crops, or the natural or built environment. The buildings look dirty.
So, what should we do to reduce air pollution?
