Currently our world is plagued by a large number of problems, most of which are caused by man, among which are the contamination of a significant amount of its water sources. If you want to know everything about the pollution of rivers and lakes, we invite you to continue reading this interesting article.
What is the Pollution of Rivers and Lakes?
There are many ways to explain what pollution of rivers and lakes is. One of them, and the most common, is the one related to the accumulation of one or more non-aquatic substances that bring with them a significant number of very harmful consequences (such as diseases) for life, both in animal species , plants and above all, for human beings who live near these types of freshwater ecosystems on planet Earth.
Of course, not only the contamination of lakes and rivers is the only contamination of this type, there are more sources of water that are affected, such as: the seas, underground wells and even the oceans. Before continuing, it is necessary to remember that water is one of the most important elements of life on planet Earth; since it constitutes 75% of the entire surface except that it is used for a large number of purposes.
Causes of pollution
In general terms, it can be said that this type of pollution is generated mainly by various human activities, which add elements that damage the environment, especially to the reserves of this important liquid for the preservation of life, which is why it is convenient learn even more about the two sources of pollution caused by humans and that in particular alter the composition and arrangement of rivers and lakes:
Major sources of river and lake pollution: These forms of river and lake pollution are those that release pollutants of varying severity in different locations throughout any country. These discharges generally occur through pipes or drains into surface waters. Examples of these sources include factories, wastewater treatment plants, oil wells, and ships carrying oil.
Ambiguous sources: These sources of river and lake pollution are those that cannot be definitively and precisely identified. Most examples used to explain these sources include traffic, pollutants carried by rivers, and pollutants that travel through underground channels. They are poorly understood because their origin cannot be controlled, as they are completely decentralized.
However, below, we will talk specifically about some specific causes, since they greatly affect the health of rivers and lakes, and it is necessary to mention and explain them to achieve greater awareness of prevention and sanitation, in order to avoid the spread of polluting agents and to be able to count on the precious liquid in conditions suitable for consumption, in industry, in agriculture, among other uses that can be given to it.
Causes of organic waste: Another common cause of water pollution is solid waste, including laundry and dishwashing waste, which requires proper sewer maintenance and is considered a lifelong priority. Many organizations have begun addressing the issue of this type of wastewater. However, in less developed countries, this is complicated because many residents lack adequate sanitation.
Industries and factories: This source is always mentioned when discussing river and lake pollution because it accounts for the largest share of the contamination, generating truly harmful and often permanent environmental effects. Furthermore, many industrial companies or factories that use freshwater end up discharging their waste into natural areas.
On the other hand, this causes all the used chemical waste to accumulate. In addition, industrial waste is often based on chemical compounds such as asbestos, lead, mercury, nitrates, sulfur and oils, which are components that deteriorate the composition of the water immediately and at the same time, that of the different species of marine animals and flora that are found living in each of the affected rivers and lakes.
Air pollution: believe it or not, it's true. The large accumulation of different types of chemical compounds in the air, especially carbon-based ones, creates a major environmental problem that can even lead to pollution in rivers and lakes. This includes pollution generated by water vapor emitted by industries, which produces acid rain and thus a highly contaminated water cycle that affects water quality in the long term.
Consequences of Pollution
Knowing in depth each one of the causes that generate this great environmental problem, one must think a lot about what are the consequences that the contamination of rivers and lakes in the world brings, since, in this way, a collective and individual conscience can be generated. that could produce important changes in the future. The following paragraphs present the main consequences that currently exist and affect us all equally:
Fauna in mortal danger: The contamination of rivers and lakes is a big problem for every animal species that exists on the planet, not only because the consumption of water found in these types of ecosystems can bring diseases, but it can also lead to the imminent extinction of the species that inhabit it. In this way, an imbalance in nature can be generated that can affect the lives of human beings.
Stagnation of food sources : Regarding this consequence of the pollution of rivers and lakes, it can be said that, as the conditions and general state of the water in the seas and in all its sources change, the effectiveness of the natural food chain is gradually changing due to the presence of various pollutants such as lead and cadmium that small animals consume within the surface.
The problem is that large animals eat small animals that have been infected by the harmful substances produced by this contamination, causing them to be affected as well. It can even be said that if humans feed on them, they can see their health deteriorate. In general, you can also see that this has an impact on the food chain, which is decreasing considerably and becoming more and more noticeable over the years.
Destruction of various environments: Due to the large quantities of waste produced by humans and often dumped into rivers and lakes, these environments and their surroundings have suffered total or partial destruction. For example, in various cities in developing countries with rivers running through them, the water's murky color is evident, demonstrating pollution caused by senseless human intervention.
Acid rain generation: The pollution of rivers and lakes with various chemicals used by humans not only causes a change in the water's pH level, but also generates other changes that cause water vapor from these polluted waters to accumulate in clouds, resulting in acid rain emissions. It should be noted that while not all types of soil are affected, the flora and fauna of the affected area will be severely impacted.
Are there solutions for the contamination of rivers and lakes?
Mentioning the various solutions to the pollution of rivers and lakes is a very easy task to explain. Currently there are many ways to keep the pollution of rivers and lakes controlled, even to eliminate it completely if the measures are applied correctly and in the necessary time. Therefore, in the following paragraphs you will learn about some possible solutions to this environmental problem that affects so many of us today:
Promoting an effective solution with the main industries that affect these ecosystems: it is well known that industry has been largely responsible for the pollution of rivers and lakes, as well as other types of pollution, such as air and soil pollution. Therefore, it is time to address this aspect of human activity in order to restore the environmental balance of the planet we live on.
One of the greatest solutions that has been applied is the promotion and approval of laws and regulations in many developed and developing countries that force the industry to eliminate the waste they leave in the environment, including bodies of water and surfaces. terrestrial, to reduce pollutants that are increasingly becoming part of the life cycle of each of the most important rivers and lakes on our planet.
Changing the mode of transport: one of the best ways to avoid pollution is to use vehicles that run on electricity instead of fossil fuels, since residents automatically begin to reduce pollution levels in rivers and lakes, therefore there are no gases that affect the atmosphere, there are no clouds with acidified water vapor and with it, there is no acid rain, which is one of the main ways of polluting the vital fluid.
In the absence of water polluting motor oils, antifreeze or car chemicals, it will greatly reduce the water pollution they have caused for many years. Likewise, it is necessary to maintain the vehicle in such a way that the garbage does not end up in the environment or thrown into the water tributaries, since it will undoubtedly have an impact that will significantly affect the vitality of the environment.
Agricultural solutions: Agricultural activities have also had a significant impact on the pollution of rivers and lakes. Therefore, several solutions have been proposed for the agricultural system worldwide to reduce pollution of rivers, lakes, and other water sources. These proposals focus on abandoning the use of fertilizers, including pesticides, which severely impact the lifespan of these ecosystems.
Controlling what is thrown into bodies of water: Properly disposing of waste products or everyday items is a simpler process than having to apply corrective measures later. Likewise, the proper management of discarded waste will greatly help control the entry of external agents into the water cycle, because these are the agents that, in principle, affect the entire water surface in any of its forms.
Filtering river and lake water: there are many proposals based on this, one of which is to treat these water sources in a non-polluting way to make them clean and even drinkable. Most often, filtration devices are used, which contain a component that retains all contaminants and allows only clean water to flow through.
