Fresh water is a basic resource for life, probably the main natural resource, and its scarcity has a lot to do with its waste and pollution for different reasons. Likewise, if we take into account the extreme events that climate change brings, we will find another reason why the world suffers and will suffer from a significant lack of water.
In this case, it will be due to the droughts that lie ahead as well as the desertification processes that the advance of global warming entails, with which either due to its contamination, use and abuse, or because it is a scarce good, water sweet is a priority resource.
On the other hand, the pollution of seas and oceans constitutes another of the great concerns of the 21st century. Both due to the health problems caused by the imbalance of the marine ecosystem, a source of food, and the environmental impact caused by said pollution, the seas are in an increasingly worse state. Keep reading Green Ecologist to know in detail the causes and consequences of water pollution.
To begin with, we want to clarify that the definition of water pollution can be summarized as any change at a physical, biological or chemical level in the water that causes its quality to decrease and that is harmful to any living being consume it.
Thus this natural resource, once damaged by pollutants, it is no longer useful for living beings, including humans, and for countless activities (from living or swimming in it and drinking it, to using it to water vegetation or wash food).
Indeed, to better understand the problems related to water pollution It is essential to address its main causes, the various Types of pollution, as well as pointing out some measures to reduce this tremendous problem. Not in vain, without quality water it is impossible to guarantee the environmental balance, of the human species, animals and plants.
Contaminated water is that whose "composition has been modified so that it does not meet the conditions for its intended use in its natural state", according to the definition of the World Health Organization (WHO). Or, what is the same, pollution is the introduction of pollutants into a given ecosystem.
We can mention two types of water or aquatic pollution:
Here we talk about main causes of water pollution, both natural and derived from human activity, as well as the main pollutants, agents or sources of pollution.
With regard to natural causes, we can cite the increased temperatures, being able to consider as such only the part that belongs to the natural process of the planet and not accelerated global warming, as is well known, it has an anthropogenic origin, that is, derived from human actions.
Pollution related to your natural cycle It can be due to contact with certain pollutants that can be from mineral or organic substances that exist in nature, for example in the earth's crust, the atmosphere or the water itself. Sometimes it is introduced by rare natural phenomena, such as floods or landslides, for example, and it is in doing so that contamination occurs.
The most important and harmful pollution is that produced by humans for different causes, including the spillage of toxic substances thrown into water on a regular or occasional basis, as is the case with industrial discharges into water. This is how water becomes cumulatively contaminated.
Pesticides, chemical fertilizers, hydrocarbons, wastewater, detergents, plastics and other solid waste end up in rivers and seas, where in addition to their environmental impact, after being ingested by small marine organisms they end up entering the food chain .
Without forgetting, likewise, that the pollution of rivers also increases marine pollution, in addition to underground seeps contaminated by toxic discharges of any kind.
In summary, the polluting agents or sources of aquatic pollution are:
As we have already clarified, some have their origin or source in the natural environment and others from the hand of humans.
We recommend that you expand this information with this other article by Green Ecologist on What are the pollutants in water.
We continue talking about water pollution around the world going into detail about the health effects and consequences of water pollution:
Water is an essential element not only for human life, but for life in general. As it is an essential element for it, its pollution is a serious blow to living beings. These are the effects and consequences of water pollution on the environment or, what is the same, its environmental impact:
Gone are those times when it was considered that the sea allowed everything due to its immensity and depth. Logically, this is not the case and they have not been slow to show. the consequences of dumping garbage and chemicals in huge quantities. Its degradation in recent centuries has taken a particular toll on coastal areas, at the same rate that industrial discharges and runoff from intensive agriculture and urbanization have increased. Not forgetting the environmental disasters caused by oil leaks, both in the sea and in the rivers.
If pollution is not important, ecosystems have the ability to clean themselves and regain their balance, the problem is beyond nature's control when you reach a point of no return.
The collapse occurs when pollutants unbalance the system without the possibility of it absorbing said pollution. In these cases, it is necessary to act, although in many cases they are problems of such magnitude that solving them is simply a utopia.
At least, that's the way it is today when problems refer to issues as tricky as plastic pollution in seas, chemical pollution in rivers or, for example, oil spills in both seas and rivers.
In this sense, it is important to carry out actions that improve the situation in order to minimize its environmental impact, as well as the threat it poses to public health, even though they may not offer ideal results.
In many cases, for example, purification or other purifying treatments do not perform a total decontamination, but it is also true that their need will depend on the use that will be given to the water. But above all, prevention is essential, both from a legal and awareness point of view and through technologies that allow carrying out really effective performances.
Here you can learn more about the proposals for Solutions to water pollution.
After reading this information, you may wonder what are the solutions for water pollution. These are some ideas both to solve the current problem and to prevent more from being produced:
In this other article we will show you more about How to avoid water pollution, to try not to continue adding more to the existing one.
Here we leave you a series of data on water pollution collected in 2022, being the most recent in 2022. Most of these data have been extracted from the study carried out by scientists Mason, S. A., Welch, V. G., and Neratko, J., in 2022 and published in Frontiers in chemistry under the title Synthetic polymer contamination in bottled water, well plastics are one of the biggest problems today.
To end this article on the water pollution, we leave below more photos of water pollution that clearly show the great environmental problem that we all suffer.
