Water is a liquid substance of vital importance for every human being, since 65% of the human body weight is water. It is the largest part of our entire blood system and is responsible for cleaning our kidneys of toxic substances, among other functions. In the same way that water keeps us alive and afloat, it is also responsible for many of the human activities, such as industry or mining. It is important for all types of life and therefore care must be taken with its use and maintenance, since there are pollutants, both artificial, caused by humans, and natural that can put it at risk.

Although it may not seem like it, all kinds of components are present in water. For this reason, it is not surprising that even those most natural components also intervene in the contamination of the water of rivers, seas and long lines, for example.
We understand by natural pollutants of water all those natural phenomena or elements that pollute nature and are caused by humans. Even so, many times these natural pollutants are aggravated by our activities. The main natural pollutants in water are:
Next, we are going to explain water pollutants one by one, and in more detail, so that you can learn how water is polluted naturally.

The effect of global warming on water goes from one extreme to another: from floods to droughts. Approximately 93% of global warming on Earth is due to heat trapped and stored in the oceans, which has consequences on the temperature and circulation of water. This fact has been taking place since the 1950s, but now is when we are seeing its effects the most.
The increased temperatures It is causing the ice sheets to melt, thus increasing the water level and changing the water cycle. In addition, its quality also decreases since sediment is dragged. Another side effect of rising temperatures is the loss of biodiversity, since marine animals are forced to move in order to survive or even some of them die.
Here you can find more information on How to avoid global warming.
Related to the previous water pollutant, we also highlight the floods generated by the rains. When floods occur, excess water carries with it all kinds of toxic substances (like fertilizers or pesticides), dead animals and waste of all kinds that devastate the area. This pollutant can affect people's hygiene and even trigger diseases diseases caused by contaminated water, such as cholera or typhoid fever, since pathogenic microorganisms end up in the water. On the other hand, there is also damage to infrastructure and the economy, for example.

Another way of naturally polluting water is coastal erosion. It's about a natural phenomenon caused by the combination of processes meteorological, climatic, hydrodynamic and sedimentary with the shape of the coast. This interaction between processes causes a shoreline modification. This natural phenomenon pollutes the water, since the erosion of the soil, the sediment and the dust of the coast end up in the sea water. In the case of erosions in areas where there is no water, the dislodged elements reach canals and the contaminated water infects drinking water.

Maybe when we think of the ash released by a volcano When it erupts, we relate it more to air pollution, but we must not forget that the ash that falls into the water also pollutes it. Therefore, we are facing a form of pollution of the sea and contamination of fresh water, depending on how far the ash reaches. When the ash falls into the water, what it causes is that the oxygen in it is reduced. Basically, the ash is biodegraded by bacteria that consume the dissolved oxygen. When this decreased oxygen dissolved in water, the aquatic fauna that needs it to live can be endangered.
With the presence of ash, lava and other elements washed into the water, it becomes much more cloudy. In addition, the contact between lava and water can generate a acid rain.

We find bacteria in almost every part of the planet: the earth, living things, air and water. In fact, they are the oldest known way of life. It is not surprising that bacteria exist in the water and that some of them can contaminate the water and cause health damage.
An example of this is the bacterium E. coli (Escherichia coli), which is only present in the human intestine and other warm-blooded animals. Due to floods or heavy rains, as we have explained previously, this bacterium can creep in through sewage overflows. The water contaminated by this overflow can contaminate drinking water sources and cause fever and vomiting or abdominal pain.
Here you can find out what types of bacteria exist.
According to the Food and Agriculture Organization of the United Nations (FAO), it is estimated that one in five developing countries will suffer from water scarcity problems before 2030. In fact, they are currently 2.2 million people who do not have access to drinking water and another 4.2 million people who also sanitation systems are lacking of safe water. This data is only one of the many Consequences of water pollution. Some of these consequences are:
Unlike human pollution, natural water pollution is not as harmful or dangerous, since it does not usually cause high concentrations of pollution. When talking about natural pollutants we know that it is more difficult to control them, so the situation worsens. Therefore, we have to become aware and try to reduce human contamination that is in our hands.
In fact, if we continue with the same rate of consumption of this natural resource and do not stop water pollution, by the year 2050, it is estimated that approximately half of the world's population will have water shortage problems.

After having explained how water gets polluted naturally, let's talk about how to avoid water pollution. Although natural water pollutants are the result of natural phenomena and elements, we cannot ignore that a large part of the responsibility for not polluting water falls on humans. Therefore, we are going to mention some recommendations to reduce water pollution:
