We never know the worth of water till the well is dry эссе

Step 1/2
Water is an essential element of life. It is the most important resource that we have on this planet. We use it for drinking, cooking, cleaning, and many other purposes. However, we often take it for granted and do not realize its true value until it is no longer available.

The phrase «we never know the worth of water, till the well is dry» is a proverb that means we do not appreciate the value of something until we lose it. This is particularly true for water. We tend to waste it, pollute it, and misuse it without realizing the consequences of our actions.

Water scarcity is a growing concern in many parts of the world. Climate change, population growth, and urbanization are putting pressure on our water resources. Many people do not have access to clean drinking water, and millions of people die every year due to water-related diseases.

«We never know the worth of water till the well is dry.»

Thomas Fuller

Water pollution is the contamination of water environments like oceans, rivers, lakes or groundwater.

Contaminants are introduced into the natural environmental system which is often caused by human behavior.

Water pollution is a big environmental problem since it not only affects animals and plants, but also our daily lives in the form of polluted lakes and rivers which in turn can lead to contaminated drinking water.

Types of Water Pollution

Pollution of rivers

Pollution of lakes

Marine pollution

Groundwater contamination

Pollution of rivers

Rivers are usually polluted through three major factors, namely industry, domestic and agriculture. This is due to the fact that each of them is usually located quite near rivers for historical reasons. This causes problems since farmers put their fertilizers on their fields.

Due to heavy rainfalls, this fertilizer may be washed through the soil and eventually end up in rivers. This can cause a dramatic increase in phosphate and nitrate concentration. In turn, this leads to an increase in algae. At the end of the lifespan of an alga, it is decomposed by bacteria which grow exponentially and use up quite a lot of oxygen.

At one point, there is too much algae contamination and thus due to a lack of oxygen, fishes and other animals die. Another source of polluted rivers is the chemical industry. Waste products from chemical processes are often accidentally or even intentionally disposed into rivers, including toxic substances like cyanide, lead or mercury.

This contamination through chemical substances is also a huge source of river contamination and destroys many river environments.

Pollution of lakes

Analogous to the pollution of rivers, the main sources for lake pollution are the excessive use of fertilizers and metals from industrial waste disposal. Moreover, lakes are also polluted through natural sediments like silt and clay which in large amounts can become a vast pollution problem.

Marine pollution

Since rivers end in lakes and oceans, they carry their contaminants in these environments. Oceans pollution thus is caused by the previous pollution of rivers and lakes and has similar pollution sources.

Groundwater contamination

Groundwater pollution occurs from man-made products such as oil, gasoline, chemicals road salts and other human-made substances get eventually through the soil into the groundwater. These substances include, among others, motor oil, substances from mining activities, toxic chemicals and untreated waste.

How can Water Pollution be measured?

Water contamination can be measured through an analysis of water samples. Chemical, biological and physical examinations can be performed.

To ensure a high water quality, there has to be a profound control mechanism which requires appropriate infrastructure, including sewage, wastewater, industrial and agricultural wastewater treatment plants to protect water bodies from contaminated wastewater.

Nature-based measures may be another approach to mitigate water contamination.

Which Countries struggle with Water Pollution?

There are many countries in the world with bad drinking water conditions. The worst conditions can be found in Mexico, Congo, Pakistan, Bhutan, Ghana, Nepal, Cambodia, Nigeria, Ethiopia and Uganda. As of 2017, almost 40% of people in Uganda need to travel more than 30 minutes to access safe drinking water.

How many People die from Water Pollution?

According to an estimate of the world health organization, approximately 3.6 million people die from water-related diseases a year.

Development of Water Pollution over Time

With the advent of the industrial revolution, water pollution increased dramatically. This is mainly due to the fact that factories released pollutants directly in rivers. Even today, in developing countries, 70% of industrial waste is still just dumped untreated into lakes and rivers.

Water pollution caused by natural phenomena

But there are also natural causes for water pollution. Natural sources of water pollution can be volcanoes, storms or earthquakes, which can have a dramatic impact on the ecological status of water.

Water pollution caused by human behavior

There are many sources of water pollution caused by humans, including the disposal of industrial waste and sewage, littering, using harmful and/or excessive fertilizers or dumping industrial waste into rivers and lakes. Moreover, the improper disposal of batteries, personal care products and household chemicals contribute to water contamination.

Sewage

Wastewater and sewage are a by-product of daily life and thus produced by each household. It is produced through various activities in our daily lives, like from using dishwashers, toilets soaps and detergents. Wastewater contains chemicals and bacteria which are harmful for human and environmental health. Germs in the sewage can cause severe health problems, which in the worst case even cause death.

Moreover, when these germs make their way into rivers or lakes, animals also may get infected. They can act as carriers for the potentially deadly diseases and thus spread them back to humans through wildlife interactions or even only from consuming animals like infected deer.

Industrial waste

Industries located near rivers and lakes are a huge problem to water quality. Since they want to get rid of their industrial by-products, chemicals like mercury, asbestos, sulfur, nitrates and many others are often dumped into nearby water. Since rivers often end in oceans, this problem impacts the whole worldwide water system.

Due to this contamination, there can be a serious adverse impact on water animals and in turn even on us consuming fish or other sea food. This is a problem which is mostly prevalent in developing countries. Developed countries usually have strict environmental standards to prevent this kind of environmental pollution.

Private Waste

ndustrial waste is a much bigger factor when it comes to water pollution than private waste. However, if households do not dispose their garbage properly, pollutants can get into the groundwater. Thus, it is necessary even for private persons to pay attention how to dispose different forms of garbage properly.

Mining

When miners extract gold, diamonds, coal or other elements, they have to take great care not to pollute the groundwater. Many of the raw minerals are containing chemicals that are harmful to the environment. If not disposed properly, these by-products can cause severe contaminations of rivers and lakes as well as of the groundwater.

Moreover, in some countries, the use of toxic substances to extract metals is a big danger to the people operation with them an also for the groundwater. For example, there are people in Africa extracting gold with the help of mercury, not even wearing gloves. Apart from the deadly consequences for the workers, if the mercury is not disposed properly, it would have an enormous severe impact on the water cycle.

Oil leakages

Accidental oil leakages are a huge problem to the marine water conditions. If due to an accident, a ship which is carrying large amounts of oil starts to leak, this impacts almost every sea creature in a severe adverse way. The bad part about oil is that it doesn’t dissolve in water, so it basically will last forever and cause health problems for fish and other animals.

Dumping

A part of our daily garbage is not burned but is carried to other countries which then dispose this garbage into the sea. This process is devastating to the whole ecological system since items like plastic and rubber take more than a century to decompose. If this process is not stopped soon, this will have dramatic consequences for ocean animals and thus in turn for us consuming fish and other seafood.

Fossil fuels

The burning of fossil fuels leads to acid rain, which in turn spills into rivers, lakes, oceans and the groundwater. By no longer using fossil fuels and transit to renewable energies, water contamination could be vastly mitigated.

Increasing meat consumption

Our worldwide increasing appetite for meat is indirectly causing water pollution. Since our farm animals have to be fed, a higher consumption of meat means a higher demand for animal feed which means a higher level of used fertilizer in order to be able to meet this demand which indirectly translates into a higher concentration of nitrate and phosphate in our groundwater.

Chemical fertilizers

For farmers, using chemical fertilizers in order to increase crop yields is considered the worldwide standard today. However, the chemicals contained in the fertilizer can sink in the groundwater and cause severe damage to water conditions.

Pesticides

Similar to chemical fertilizers, the use of pesticides increases the yield of farmers since it protects the crops of plants from animals. However, these pesticides often contain harmful substances which will get in the ecosystem sooner or later and thus foster water pollution.

Leaking sewer lines

A leak in or even a broken sewer line can pollute the groundwater to a significant degree. Leakages in the sewer line may often not be detected for a while and can contaminate the groundwater for this timespan until the leakages are fixed.

Radioactive garbage

Radioactive waste is a by-product in the production of nuclear energy. It takes a high level of caution to store the nuclear waste in a safely manner. The disposal of nuclear waste is quite difficult and takes enormous effort. Thus, it is quite expensive to safely dispose the nuclear garbage. Mistakes in the disposal process of nuclear waste can result severe damage of the ecosystem through the nuclear contamination of the groundwater.

Leakage of landfills

Leakages of landfills can result in the pollution of water in a severe manner. There are many toxic substances which can flow through the leakages and thus contaminate the groundwater.

Urban development

In our daily lifes, our standards and entitlement continually grow. We need the hippest clothes, trendy food and other amenities. The downside to this is that we dispose things that are still working but are not trendy anymore quite faster than decades ago.

This leads to a huge waste of resources, since the production of material things causes huge water and resource demand. Thus, more fertilizer and other chemicals have to be used in order to meet the demand for resources which in turn leads to an increased contamination of our water supply.

Population growth

Similar to the urban development issue, the growth in population leads to an increase in demand for food and other things for daily life. Thus, an increase in population is likely to cause an increase in water pollution if we do not adopt properly and develop an overall strategy that on the one hand meets the demand for material goods and on the other hand is in line with sustainable ecological behavior.

Animal waste

Animal waste is a natural product. However, when it rains, it reaches rivers and can under some circumstances to diseases which may impact humans in the form of Cholera or Diarrhea.

Underground storage leaks

Oil and other substances are often carried through pipelines. If this pipelines leak, oil and other harmful substances can get in the groundwater and cause an adverse impact on the water quality.

Airplane fuel drops

Prior to the landing, airplanes usually drop their fuel if there is still too much of it in the plane’s tank. This drop of fuel causes air pollution which in turn can harm water quality through contaminated rain.

Effects of Water Pollution

Effects on humans

Effects on animals

Effects on plants

Effects on water animals and plants

Disruption of the food chain

Diseases

Eutrophication

Destruction of whole ecosystems

Effects on humans

Water pollution poses severe threats to humanity. Since water is crucial for all life on earth, a lack of pure drinking water could result in a decrease of population numbers. Moreover, if water becomes a scarce resource, people are likely to fight for their share and this may even lead to wars.

This problem will be especially severe in countries which are heavily affected by the global warming problem. In these countries, the water shortage will be a quite severe problem. If we continue to pollute our rivers, lakes and oceans, the time will come when water will be an extreme precious resource and prices for water will increase dramatically.

Effects on animals

Animals are also severely affected by water pollution. In contrast to humans, animals are not able to recycle or treat water but they still need it to survive. Thus, they have to consume the contaminated water and risk to get sick. If the water is too polluted, local animals may either move to other places or if they are not able to move will eventually die from the contaminated water and its adverse health effects.

Effects on plants

Plants can also be affected by water pollution. Since the water system is connected, pollution in rivers can transfer into a pollution of lakes and the groundwater. Plants which grow in a contaminated area may use this polluted water and die off. Moreover, if farmers use the contaminated water for their fields, the plants will suffer and therefore crop yields may decrease.

Effects on water animals and plants

There are also significant adverse effects on water animals and plants from water pollution. Rivers, lakes or oceans are the natural living habitat for countless animals and plants. These animals and plants are usually quite sensitive to their living conditions. If their living environment gets polluted, they may not be able to adapt properly and eventually die due to the contaminants.

Disruption of the food chain

Moreover, water pollution can also have adverse effects on the food chain. Since we consume fish and other water animals, we also indirectly consume the pollutants which these fish have consumed. Thus, we could also be contaminated by eating contaminated fish.

Diseases

The consumption of polluted water can cause many serious health conditions. Among others, it can lead to cholera, hepatitis or typhoid fever. Thus, water pollution poses a serious threat to the health of humans as well as to the health of animals.

Eutrophication

Water pollution can also lead to the eutrophication of lakes or oceans, meaning that the growth of algae will be supported. Since algae need certain chemicals and nutrients to grow, water contaminated with those nutrients will give algae the opportunity to spread.

Destruction of whole ecosystems

Ecosystems are quite sensitive to changes in their natural conditions. Even small changes can lead to big effects. If the level of water pollution increases, some animals and plants may die off which in turn could cause chain reactions regarding predator and prey animals and therefore harm the ecosystem in a significant way.

Solutions to the Water Pollution Problem

Responsible use of fertilizer and pesticides

Discourage firms from disposing their trash in rivers, lakes or oceans

Replace fossil fuels by renewable energies

Minimize stormwater runoff

Reduce meat consumption

Support other countries to improve their technologies

Convince people

Responsible use of fertilizer and pesticides

Through the reduction in the use of fertilizers and pesticides, the contamination of the groundwater through nitrates and phosphates can be significantly reduced. Thus, we have to make sure that farmers are aware that their efforts can be a big contribution in order to mitigate water pollution.

Discourage firms from disposing their trash in rivers, lakes or oceans

We have to make sure that firms do not dispose their industrial by-products in rivers or other water environments. There are already strict regulations in developed countries, but this principle should also be standard in developing countries in order to solve our water pollution problem.

Replace fossil fuels by renewable energies

Private people and firms are getting more and more aware that fossil fuels have to be replaced by renewable energies. This is the right approach in order to reduce water pollution from acid rain.

Minimize stormwater runoff

Water pollution from stormwater runoff and the resulting sediment pollution can be avoided by private persons as well as by big firms. Sediment pollution may not seem to be a big problem to you, but it has a significant ecological impact.

Sediment in an aquatic environment can change the water temperature, screens out sunlight, disrupts the food chain, inhibits photosynthesis and eventually can lead to a decline of species in the water ecosystem. You can mitigate sediment pollution through seeding or installing a silt fence to control and contain a potential erosion.

Reduce meat consumption

Consuming lots of meat is quite common in our society today. However, this has an adverse effect on water pollution since in order to produce more meat, the intensity of fertilizer usage is likely to increase and thus the pollution of the groundwater increases. Reducing the consumption of meat can thus contribute to a reduction in water pollution.

Support other countries to improve their technologies

We have to hand developing countries the knowledge and awareness on how our actions affect water pollution and how to fix this issue. Moreover, we have to stop shipping our trash to other countries and instead deal with our trash at home. This will increase the incentive for each country to reduce trash production significantly.

Convince people

The ultimate weapon to fight water pollution is to convince people to change their behavior. This includes convincing farmers to use less fertilizers and pesticides but also refers to the behavior of private persons in their daily life. People have to be aware that reducing trash is major contribution to the reduction in water pollution. Moreover, disposing different kinds of trash appropriately makes a big difference.

Conclusion

In order to solve the water pollution problem, it takes huge efforts, time and money to set up a sustainable process and execute it. We need to put the focus on renewable energies but at the same time have to make sure that we can provide basic things for the growing population. It is also essential to increase the awareness for this big problem. We should put more attention in our daily lifes to our consumption needs.

Is it really necessary to always have the newest stuff and dump older but still working things? The need of material things is killing the planet since for the production of more things, the water will be polluted even more through the factors mentioned above. If we really want to make an impact, we need to put awareness to our consumption behavior and decrease our need for material things.

1a) Посмотрите на картинку. Какое послание она несет? Как цитаты ниже связанны с ним?

«Мы никогда не узнаем цену воде, пока не станет сухо».

(Томас Фуллер, английский историк)

I think the picture is meant to get across the message that man is destroying the Earth because a man is climbing up the stairs on top of the Earth which seems to be getting crushed. The proverb is related to it because it refers to the fact that we only realise how much something is worth until it’s gone. So as man hasn’t realised the damage he is causing he will probably only realise it when it’s too late.

Перевод:

Я думаю, что картина призвана донести сообщение, что человек губит землю, потому что карабкается вверх по лестнице на вершину земли, которая, кажется, становится сокрушенной. Пословица связана с этим, потому что ссылается на то, что мы только понимаем, сколько стоит что-либо, пока оно есть. Так как человек еще не понял, какой ущерб он причиняет, скорее всего, он поймет это когда будет слишком поздно.
