Atmospheric pollution is caused by pollutants such as smoke from factories entering the atmosphere and being carried to waterways. Industrial waste can also create polluted runoff that collects in rivers and lakes. Another reason for water pollution is chemically treated sewage. This water carries harmful chemicals and high amounts of bacteria, which can potentially lead to serious diseases. Runoff from fields can contain chemical fertilizers and pesticides which can pollute
Over 780 million people are without access to clean drinking water, and around 2.5 billion people do not have access to an adequate sanitation facility (Bradford). There are two primary ways in which water pollution is caused. The first way consists of objects such as trash from a landfill or parts of a boat which have fallen into the water. The other cause is due to fertilizers and other chemicals being spilled into the water ("Pollution"). Once enough pollutants fill the water, it becomes likely for it to become contaminated with dangerous pathogens, which survive on the pollutants and can be dangerous to the wildlife.
With more factories, farms and a higher population, it is certain there will be an increased amount of water pollution. Over time, water quality has deteriorated (thediplomat.com, 2013). In the Huai river basin, “the water pollution began in the 70s but seriously increased after the 1980s” and in 2011, the quality of the water has deteriorated compared to earlier years. As shown in Figure , from 2001 to 2010, the water stress has increased overall due to the increased amount of industries, leading to higher water pollution. Now, several major rivers have changed colour and some parts are too contaminated for human
There is a decline in the invertebrate population over a few kilometres which is an indicator of the impacts of the urban settlements. Only the stronger and toughest invertebrates live towards the lower regions of the river due to the magnitude of the pollution especially in the form of the organic matter. There is a good amount of fish in the area as the fish which are indigenous to the river are resistant to the pollution as it is a common occurrence. Sewers discharge their contents into the river which pollutes the river. This is due to urbanisation and a high population density.
There is a lot of information about water contamination, the main topics are, effects of the percentage of water contaminated, ways it gets contaminated, and what to do in the after-math. There are many effects of water contamination due to the large amount of water that has been contaminated. Approximately 85% of the world’s population lives in the driest part on the earth. Drought is a part of this issue, because there is so little water there are many people using the small amount of available water. So many people using this small amount of water causes the water to be easily contaminated.
Intro: Water pollution has caused so many problems to our waterways that no one really knows how to help. Water pollution caused; dead zones, oil spills, garbage floating around, and unsafe drinking water. People disagree about water pollution because, people have found ways to improve and help out the problem that water pollution has caused around the world. Others believe that that water pollution has created situations and are in the process of figuring out solutions. Marine life habitats are getting destroyed, marine life is declining everyday, how and where the garbage is getting into the oceans, and the drinking water is becoming seriously unsafe to drink.
It fills lakes and obstructs shipping channels, clogs hydroelectric turbines, and makes drinking water purification costlier. Besides air pollution, there is also water pollution which is also caused by many variants causing more health issues to drinking supplies. Today people oppose this argument by saying that water pollution is easily not harmful to the environment. This is not true because today because many countries have water problems due to low water sources caused by trash and erosion. Water pollution is also another harmful type of pollution that should be cleaned to better the water in the
Water pollution develops when water is defiled by different factors. Industrial and agricultural wastes are the most common factors. These factors cause imbalance in the water leading to death of some species. Water pollution in China is such an issue, to the point that the World Bank cautioned of “catastrophic consequences for the future generation. "(Facts and Details).
Many of these rivers suffer from high Biochemical Oxygen Demand (BOD). Sewage has been identified as the major source of these problems. The origins of the polluting sewage include sewage treatment plants, discharge of raw sewage from squatters, sullage of households, wet markets and eateries. In 2013, Malaysia was reported to have more than 1.2 million sewage treatment systems. These sewage treatment systems formed about 86 percent of some 1.48 million water pollution sources identified throughout the Peninsular Malaysia.
Water is a necessity for all life on Earth, yet it is one of the most threatened vital resources in the world. “Water pollution is any contamination of water with chemicals or other foreign substances” (Water Pollution). From automobile fluids that seep into sewage systems to household products that are usually poured down sinks, all these items can contribute to the destruction of the environment. However, these items have a common denominator: humans. Not enough people are aware of the dangerous effects that water pollution has towards the environment and what causes it.
