In fact, even some insignificant actions around us can contaminate water sources. Throwing a large amount of garbage or dead livestock into streams, rivers or lakes may seem like nothing, as the garbage will be washed away by the river. But that’s not the case. It can cause certain pollution to these water sources. This is just a small problem in life. When it comes to water pollution sources, there are many. In this chapter, we will explore what else needs to be done to reduce water pollution besides protecting the environment.

We know that water pollution can cause harm to the ecological environment and human health. The harmful environmental impacts of water pollution include: the accumulation of heavy metals on aquatic organisms reduces the oxygen content in water, and suspended particles decrease the amount of sunlight that penetrates into the water, thereby affecting photosynthesis.

Green agriculture, from livestock production to agricultural production, uses 70% of the earth’s surface water and causes water pollution. When it rains, some fertilizers and other substances in agriculture are washed away by the rain, which will bring these viruses and bacteria into the waterways. At this time, you can consider planting some plants near the water body to prevent chemical substances from being washed away when it rains.

At this point, reducing water pollution and protecting the environment is very important. However, there is another point to consider. For instance, in some factories and other places, the generation of wastewater and sewage cannot be avoided. What needs to be done at this time is to install water quality detectors at the sewage outlets to monitor and manage them (including online monitoring of medical wastewater, industrial process water monitoring, drinking water monitoring, etc.) Ensure that all the sewage has been treated and tested to meet the standards before being discharged.

Let’s do our best to prevent and control water pollution, starting from ourselves! This includes water conservation, always obtaining clean and pure water sources, and ensuring the safety of water sources such as rivers, lakes, oceans, groundwater, and surface water!
