In most of the cities the Municipal Solid Wastes are disposed in open dumps located few meters away from the streets and residential areas, or dumped into drainages which flow into streams which are the source of water supply to the residents of such localities. These unscientific and improper disposal practices cause severe environments and public health hazards. This study examines a sustainable approach to municipal solid waste (MSW) management and recommends proper methods of MSW management. This way, proper management of MSW will improve air, water, soil quality and reduce the health hazards associated with the people living and working in such areas are subjected to, but it would also reduce the rate at which green house gases and other poisonous gases are emitted in the atmosphere, leading to global warming. Waste collection is a tedious task that requires management of a large amount of money and human resource as well.
Also we can't burn this trash as much as we want because it gives of a small amount of CO2. This has been going on since the world started to produce more. We throw away food, clothes, materials, etc. that can be recycled and reused so that we don’t have waste build up. The world needs to reduce the amount of waste we produce every year so the future won’t have to deal with the problem.
Everyone contributes to air pollution in their own way. Pollution is emitted by cars, power plants, boilers, refineries, and other sources. The ozone is deteriorating because of human activities, which will eventually cause harm to us. Luckily for us there are solutions. The first solution is for humans to try and stop driving so much, start riding bikes or walking more often.
Most industries requires large amounts of water for their work. When involved in a series of processes the water comes into contacts with heavy metals, harmful chemicals, radioactive waste and even organic sludge. These are either dumped into open ocean or rivers, or the water that has been polluted by them is released into the ground. As a results, many of our water sources have trace amounts of industrial waste in them and it seriously impacts the health of our eco-system. This water is used for irrigation, washing our food at home and sometimes recycled into drinking water.
Within heavily populated cities, such as those in China, even the smallest of activities could lead to hugely negative effects for the local water bodies. Even with relatively low ecological footprints per capita, the shear volume of citizens could offset that and result in poor environmental outlooks. This is because a large population calls for increases to industry and agriculture, which contribute to water pollution individually (Shao et al., 2006). Industrialization introduces so many chemicals into the waters, and the fertilizer and pesticides used in industrial farming also greatly pollutes water. Such activities have created a reality where toxicants are now mainly absorbed directly from food because of the heavy contamination of water sources, such as lakes and fresh water bodies.
Sometimes doing things illegally, placing pipelines that spill oil and other toxic substances or take the only thing that community has, water. Many problems such as mercury exposure, water safety, shortage of food and heat make America a target for environmental issues. The fast life in America ruins people, so sometimes taking charge in your community gives life a different meaning. Opening a garden, a recycling center or even planting trees can open the souls of many and give life back to others. Like I stated before change can be small yet it will make a difference to others and the
Not only are new technologies taking a stand to pollution, so are factories. According to a N.A.S.A. video, “coal burning plants have cut out a lot of the harmful pollutants before they reach the air” (CNN 2014). Factories are a big part in the contribution to pollution. By coal-burning plants trying to eliminate their amount of pollution, it can make a huge difference in how much cleaner the air can be.
EFFECT The effects on the city and water supply have been enormous.To start with, the means of water supply have been transformed into open sewers. The consequence of people using water canals to clean their clothes is that the detergent used has spread. The detergent cannot dissolve due to the concentration of chemicals in the already contaminated water, and spreads throughout the canal and kills fishes and other living organisms. As for the waste produced by industries and factories, lots of this waste contains heavy metals: when it is dumped into the open canals, these toxic, poisonous metals are dumped along with it. One of the most toxic metals is mercury, which can have very serious side effects if ingested in excess, including paralysis, liver and kidney failure, and death.
That mollusk is the essential food for the people in that city. Several issues have been rising up even now, that our world becoming deteriorated as a result of the environmental pollution, not only in the air, but also in the fresh water. Moreover, it has been happening in our country recently, especially in my city. Because of the pollution, the river that ordinarily is used for irrigation, has been polluted by the activity of factories that wasted a heavy metal, which is recognized generally it as Pb. My supervisor and I, observed and founded the best solution to help people in that city before processing the freshwater mollusk for a staple food and limiting the level of the heavy metal in that mollusc before they consume.
The air-conditioner will filter the air and remove the dust and bacteria. However, it consumes lots of electricity . When the electricity is generated, it will produce lots of green house gases and the pollutants. Therefore, it aggravates the global warming and the air pollution. Another drawback is harm for respiratory health problem .
