Water pollution is a matter of concern to many agencies. Water pollution greatly affects human life and health. So how does water pollution happen?1. The role of water in health
Water pollution can lead to the transmission of a number of dangerous diseases such as cholera, diarrhea, dysentery, hepatitis A, typhoid or polio. In the past, when water resources were not cared for and improved in quality, people's health was under many threats. Clean water can be considered as a precious and finite resource that needs to be protected and continuously appraised.Water pollution in the city is a common problem in today's fast and strong development. Along with that development, pollution also increases rapidly. Therefore, water pollution in urban areas should be paid more attention by the Department of Natural Resources and Environment and the people.
Clean water is important to the socio-economic life of a country or the whole world. When water is guaranteed, health risks are also minimized. As a result, production activities are promoted, contributing to economic growth. Most importantly, when the water source is guaranteed, those with weak immune systems will limit the risk of disease.
With important influence, WHO always appreciates the value of water. Therefore, water pollution problems need to be paid attention to in order to find the cause and fix it in time. If water is the source of life, clean water is a finite and incomparable precious resource.
2. What is water pollution?
The problem of water pollution is becoming more and more widespread and threatens the health and life of all living things on Earth. Although water accounts for most of the structure, very little of it can be used for daily life. Therefore, maintaining the purity and ensuring the quality of water sources is one of the long-term goals of all mankind.Water pollution often comes from harmful chemicals or microorganisms. Pollution can become more serious when we do not detect and block the movement of polluted water. The waste will follow the water currents that go everywhere and eventually go to the ocean, destroying the natural ecosystem and seriously affecting the environment of aquatic species.
3. Causes of water pollution
Water is an organic liquid or solvent that can dissolve many impurities. Because of this feature, water pollution easily occurs and spreads quickly. Water pollution in cities is often more at risk than in rural areas because activities from factories and industrial zones release toxic gases every day.Water is contaminated directly or indirectly through various forms. For example, toxic fumes are trapped in the cloud mass until enough water vapor accumulates and other conditions produce rain. Falling rain contains many impurities that will seep into the soil and water sources, causing each field to be polluted. More dangerous is that in rain water containing toxins, if we go outside without shielding, it can be dangerous for each of us.

4. Sources of water pollution in the city
Cities have rapid industrial development, leading to a higher risk of water pollution than rural areas. The following is a list of some items about water sources in the city that are at high risk of being polluted:Groundwater sources Rain falls and seeps into the soil over time that amount of water will slowly seep into the groundwater. At the same time, groundwater acts as a source of clean water to supply all human activities. Therefore, the problem of groundwater pollution brings serious effects to daily life and production.
In addition to rain water, all the chemicals used for cultivation also cause a lot of impact on groundwater. Another part is due to the slow decomposition of inorganic waste, causing serious environmental pollution. Plastic bags and other types of plastic bottles are estimated to take millions of years to completely decompose from the earth. Not to mention, when groundwater is polluted, other sources will be at risk of more serious pollution. If one day that happens, people will not be able to find clean water for daily life.
Surface water pollution More than 70% of the earth's surface is covered by water. Thanks to the presence of water, the low-lying areas are filled, forming waterways that are convenient for human movement. Thanks to water, aquatic species also constantly develop and create biodiversity. On the world map blue is the symbol for water.
When the surface water is polluted, we will not be able to swim, boat or fish here. Not to mention surface water comes in direct contact with the air and affects us when we get close.
Sea water According to statistics, 80% of the ocean is facing a pollution problem from mild to severe. The main pollutants found are chemicals, heavy metals, garbage.... These causes are found from farms, factories, industrial zones and water currents. They are dissolved in water and then flowed everywhere, finally being discharged into the ocean.
On the surface of the ocean, it is no longer a stranger to plastic waste or plastic bags. From many different sources of water, most of the waste has been dumped into the ocean partly because it can be picked up and can be picked up again and sink to the bottom, causing many aquatic species to be poisoned leading to loss of quantity and diversity. inherent in the ocean. Pollution caused by carbon dioxide or oil spills has caused the oceans to suffer a lot of serious damage.
There are many statistics that say 25% when carbon dioxide affects the environment and water sources comes from humans. Therefore, each of us needs to raise the awareness of protecting environmental resources to ensure daily life.

5. Types of water pollution and their effects
In addition to pollution of domestic water or ocean water, water pollution also affects a number of areas in life. The following are common types of pollution:Agriculture The agricultural industry needs a significant contribution of water to maintain farming and livestock activities. However, agriculture is also the cause of serious water pollution. Pesticides or fertilizers from the farm can be washed away when it rains. From there, nutrients that are good for plants follow the water flow into the air or mix with the water source.
This problem, when not detected and handled in time, will endanger the lives of each of us. In addition, some chemical fertilizers stimulate the growth of poisonous plants in the ocean. Water sources will increase the risk of poisoning and the marine population will be seriously threatened.
Industry Industrial waste according to regulations needs to be treated and filtered many times before being discharged into the environment. However, in order to save costs and time, many businesses secretly discharge industrial waste into rivers, streams, ponds and lakes. Water occupies 3⁄4 of the surface but is a limited resource that can be reused over and over again. Therefore, the intrusion of pollution sources increasingly reduces the natural clean water source.
Oil and Gas Pollution caused by the oil and gas industry has received a lot of attention and attention in the groups of causes. In recent years oil spill incidents and remediation have been promoted to restore balance to the ocean. If the oil leak is not quickly remedied, polluted oceans and marine animals are also at risk of extinction.
Radioactive substances Radioactive substances from nuclear plants can be considered a new source of pollution but are extremely dangerous. When mining Uranium to serve factories, there is a radioactive amount of radiation released into the living environment. At the same time, this is also the material for military weapons when war breaks out.
Radioactive contamination is quite difficult to deal with. It takes quite a long time to decay one mole of this substance. Therefore, they cause complications and threaten health according to genetic factors. During the war, our country appeared many dangerous diseases caused by bombs and bullets.
If they get into the water, it will be a great threat to humans in the distant future. Therefore, regardless of the cause of water pollution, it needs to be treated and minimized to protect human life and health and other species on earth.

6. Solutions to reduce water pollution
To prevent and reduce water pollution you need to act quickly to protect the environment. The simplest thing we can do is not use non-biodegradable waste. Learn how to separate waste and use biodegradable products instead to limit the pollution caused by waste. Organic waste bio-products are easier to decompose and recycle and are less hazardous.In addition to your own actions, you need to propagate to those around you so that they can have a different view of the task of protecting water sources. In addition, the government and functional agencies need to tighten and strengthen laws on natural resources and environment to punish and deter bad behaviors that pollute water sources.
Water pollution can happen due to many reasons. However, most of the causes come from people themselves. Let's each be more aware to join hands to protect the place we live and exist.
