The problem of today

Environmental pollution is one of the biggest problems in the world today. It can be defined as pollution of atmospheric air, water bodies and soils by human waste. At the moment, there is no such city and there is hardly a countryside that could be called clean and unpolluted.

Varieties of pollution

There are many types of pollution, among which the most common are air, water and soil pollution and radioactive pollution, debris, noise, light pollution and disturbance. temperature regime... Unfortunately, most of these problems are the result of human activity. In fact, the contradictions between man and nature are at a high level.

Deforestation

People are cutting down forests and thus destroying thousands of acres of land. Firstly, the soil is blown away by the winds and secondly, even if new trees are planted in place of the felled ones, they cannot return the lost forests, which were part of a complex ecosystem that purified the air and provided shelter for wild animals.

Waste

Large industrial cities generate large amounts of waste every day. They are either thrown away or buried in the ground, causing hazardous chemicals to enter the soil. Often, toxic and poisonous liquid chemicals are discharged into water bodies, endangering human health. However, people themselves are responsible for what happens.

Pollution of water bodies and atmosphere

Pollution of water bodies and the atmosphere is a serious threat to the environment. The main factors here are car exhaust fumes, oil spills, debris, etc. polluted air and water bodies affect human health to such an extent that millions of people do not have access to safe drinking water.

Conclusion

In conclusion, it should be noted that if we want to live in a better and healthier world, we must protect and care for the environment.

Environmental pollution

Largest problems

Environmental pollution is one of the largest problems in our today’s world. It can be defined as a contamination of air, water and land from man-made waste. Nowadays there aren’t any cities and hardly any rural areas that remain clean and unpolluted.

Types of pollution

There are a lot of different types of pollution among which the most recognized are air and water pollution, soil and radioactive contamination, littering, noise, light and thermal pollution. Unfortunately, most of the problems are the result of human activities. Indeed, the contradictions between man and nature are on a high level.

Deforestation

People cut down forests and thus damage thousands of acres of land. First of all, the soil can be easily blown away and secondly, even if new trees are planted, they can’t bring back the old forests that were a part of a complex ecosystem that cleaned the air and made home for wildlife.

Waste

Big industrial cities produce a lot of waste every day. It’s either thrown away or dug up which leads to the releasing of dangerous chemicals into the soil. Very often toxic or poisonous liquid chemicals are poured into the water therefore people’s health is put at risk. However, they are themselves responsible for this.

Water and air pollution

Water and air pollution are also a serious threat to our environment. The main factors contributing to them are car fumes, oil spills, throwing litter and many others. Polluted air and water affect people’s health to such an extent that millions of them have got no access to safe drinking water.

Conclusion

In conclusion, it must be said that if we want to live in a better and healthier world we should take great care of our mother nature and learn to protect it.

Our planet Earth is only a tiny part of the universe, but nowadays it’s the only place where we can live. People have lived on our planet for many years. They lived and live on different continents, in different countries. People depend on their planet, the sun, animals and plants around them. Environment is everything in the world around us that surround and affects all life on earth, including the air, food, water, plants, animals and other.

Environment is the place where we live. Since ancient time nature has served man, being the source of his life. For thousands of years people lived in harmony with environment and it seemed to them that natural riches were unlimited. But man’s interference in nature began to increase with the development of civilization. Our ecology becomes worse and worse with every new day. Many species of animals and birds are disappearing nowadays. People destruct wildlife, cut down trees to make furniture. They forget that people can't live without trees and plants, because they fill air with oxygen.

There are a lot of ecological problems. The most serious ecological problems are: noise from cars and buses; destruction of wildlife and countryside beauty; shortage of natural resources; the growth of population; pollution in its many forms. Water is everywhere, but there is no ocean or sea which is not used as a dump. Many rivers and lakes are poisoned too. Fish and reptiles can't live in them. People can't drink this water. So we have to clean the water environment. Another problem is air pollution. Air pollution influents the health of people. For example: ultraviolet radiation from the sun can cause skin cancer. Normally the ozone layer in the atmosphere protects us from such radiation, but if there are holes in the ozone layer ultraviolet radiation can get to the earth. Many scientists think that these holes are the result of air pollution. Also we have problem with nuclear pollution. Nuclear pollution cannot be seen but its effect can be terrible. To make air clear clean again we need good filters at nuclear power stations, at factories, in cars and buses.

Another problem is growth of population. They don’t have enough places to live. They need more water, more food. So it is the reason of the shortage of the natural resources. It is very difficult to solve this problem. Also one of the most serious problems is greenhouse effect. It works like this: sunlight gives us heat. Some of the heat warms the atmosphere and some of the heat goes back into space. Nowadays the heat can't go into space. That’s why winter and summer temperatures in many places have become higher. If the temperature continues growing up the snow on the mountains and ice will melt, so the most of the earth will be under water. So every person has to understand how important it is to solve these problems, which endanger people’s life.

Our environment is constantly changing. This is the fact we cannot deny. The way technological progress influences the environment is not the most favorable.

Today humanity is facing numerous environmental problems. If we do not pay attention to these problems right now, we may face even bigger natural disasters in the future.

Pollution

Pollution is one of the biggest problems. Plants and motor vehicles are number one pollutants. Their harmful emissions pollute the environment. Oil spills and acid rains make the World Ocean dirty.

Global warming

Global warming is the result of human activity. It is characterized by rising temperatures of the oceans and earth's surface causing rise in sea levels and melting of polar ice cover. Apart from that, floods, desertification and excessive snow are also signs of global warming.

Climate change

Global warming causes the rise of another serious problem, known as climate change. Climate change can lead to the development of other harmful effects in our life, such as occurrence of new diseases and change in seasons.

Deforestation

Today forests cover about 30% of land. Every year this figure decreases more and more. People clear out new territories for residential buildings, new plants and factories. We must realize that deforestation causes the extinction of animals and plants.

Ozone layer depletion

Ozone layer protects our planet from the sun’s harmful rays. Due to atmospheric emissions of the so-called CFC's, the ozone layer depletes. This results in occurrence of the holes in the ozone layer.

Today CFC's are banned in many industries. However, we must remember that if this problem is not taken under control, harmful rays of the sun will easily penetrate the atmosphere. The biggest hole in the ozone layer is located above the Antarctic.

Our environment is constantly changing. We cannot deny this fact. Technological progress does not have the most favorable impact on the environment.

Humanity today is faced with many environmental problems. If we do not pay attention to them in time, we risk facing much more serious disasters in the future.

Pollution

Pollution is one of the most big problems... Factories and cars are the worst polluters. Oil spills and acid rain pollute the oceans.

Global warming

Global warming is the result of human activity. It is characterized by an increase in the temperature of the oceans and the surface of the earth, which leads to a rise in water levels and melting of the ice sheet. In addition, flooding, desertification and excessive snowfall are also signs of global warming.

Climate change

Global warming brings with it another serious problem - climate change. Climate change can cause other harmful influences on our lives, including the emergence of new diseases and changes in weather conditions.

Deforestation

Today, 30% of the earth's surface is covered with forests. Every year there are less and less of them. Man is cutting down forests, freeing up the area for the construction of new houses, factories and enterprises. We must reflect on the fact that deforestation is leading to the extinction of animals and the extinction of plants.

Depletion of the ozone layer

The ozone layer protects our planet from harmful sunlight. Due to the release of so-called freons into the atmosphere, the ozone layer becomes thinner. This creates holes in the ozone layer.

Currently, freons are practically not used in production. However, it is worth remembering that if this problem is not brought under control, harmful sun rays can enter the atmosphere unhindered. The largest ozone hole is located over Antarctica.

Topic: Types of pollution

Nowadays nature of the Earth is strongly influenced by people. Of course, it is a fact, that human beings inhabit only the one tenth part of the land of our planet and there are places with extremely severe conditions for a comfortable life. But even there, in Amazonia, or in the Siberian wilderness the harmful impact of human life is detected by scientists. It seems rather strange, but huge metropolises, enormous plants, different goods of civilization; people began to be committed to life in pure nature. Developed countries move harmful productions to the third world countries, residents of big cities try to purchase cottages far from. Anyway, the mankind has finally realized that pollution must be stopped or reduced, or sooner or later we will have to search for another planet to live on.

Currently, the nature of the Earth is highly dependent on people. Of course, it is a fact that human beings inhabit only one tenth of the land mass of our planet and there are places with extremely difficult conditions for comfortable life... But even there, in the Amazon, or in the Siberian wilderness, the harmful effects of human life have been discovered by scientists. It seems rather strange, but having created huge megalopolises, huge factories, various benefits of civilization, people began to strive for life in pure nature. Developed countries are moving harmful industries to third world countries, residents of large cities are trying to buy cottages far from noisy megacities. In any case, humanity has finally realized that pollution must be stopped or reduced, or sooner or later we will have to look for another planet for life.

Let’s study what kinds of pollution exist and to help the Earth. four types of pollution: air, water, soil. All of them are harmful enough to cause different diseases and to destroy ecological systems. These types are strongly connected to each other, and it is likely to observe the territory where all the variety is represented. But, anyway, let’s talk about each of them separately.

Let's take a look at what types of pollution exist and what we can do to help the Earth. It is believed that there are four types of environmental pollution: air, water, soil and noise pollution. All of them are harmful enough to cause various diseases and destroy ecological systems. These types are closely related to each other, and it is quite often possible to observe the territory where all the diversity is represented. But, one way or another, let's talk about each of them separately.

The first one is air pollution. Air is a substance we can’t live without. Our atmosphere consists of oxygen, ozone and carbon dioxide in a certain proportion. This proportion is ideal for healthy and comfortable breath and it shouldn’t be changed. Various contaminants in air violate the percentage of gases and add poisonous impurities. One of the most widely known drawbacks of air pollution is stratospheric ozone depletion, due to which the climate of our planet changes and terrible natural disasters happen more frequently. The major sources of pollution in big cities are. Sulfur oxides may cause acid rains and many other bad things. Various plants and power stations exhaust harmful gases; excrete toxic metals, radioactive pollutants and ammonia. Accidents on manufactories and plants increase the pollution a million times. There is a solution for these problems: people should ecological friendly fuels, on factory chimneys accidents.

The first is air pollution. Air is a substance we cannot live without. Our atmosphere is composed of oxygen, ozone and carbon dioxide in a certain proportion. This proportion is ideal for healthy and comfortable breathing and should not be changed. Various air pollutants disturb the percentage of gases and add toxic impurities. One of the most widely known disadvantages of air pollution is the depletion of the ozone layer, which is changing the climate of our planet and causing dire natural disasters. Automobile gases are the main source of pollution in large cities. Sulfur oxides can cause acid rain and a host of other bad things. Various factories and power plants emit harmful gases, toxic metals, radioactive pollutants and ammonia. Accidents in factories and factories increase pollution a million times over. There is a solution to these problems: people must start using environmentally friendly fuels, put filter systems on factory pipes and prevent accidents.

Water pollution is an important problem to solve too. Life is impossible without clean water. Stocks of pure water on the Earth decrease very fast. Water pollution is also dangerous because it ruins not only the water bodies, and living creatures around it. Firstly, in rivers, lakes and oceans, like plastic bottles, paper and other things. Ship wrecks add trash to water areas. Secondly, products of oil refinement may cause a disastrous effect to water. In the place of an oil spill there is a thin membrane that doesn’t allow water to breathe and kills birds and other animals. A great number of plants and sewerage systems drain waste directly into the water bodies. According to the rules, all these organizations must build cleaning facilities, and people must utilize their wastes.

Water pollution is an important challenge to tackle the problem. Life is impossible without clean water. The reserves of clean water on Earth are decreasing very quickly. Water pollution is also dangerous because it destroys not only water bodies, but all vegetation and wildlife around it. First, there is a lot of garbage in rivers, lakes and oceans, like plastic bottles, paper and others. Wreckage of the ship add debris to the water areas. Second, refined petroleum products can cause catastrophic effects on the surface of the water. There is a thin membrane at the site of the oil spill that does not allow water to "breathe" and kills birds and other animals. A large number of plants and sewage systems discharge waste directly into water bodies. According to the rules, all these organizations are required to build treatment facilities and people must dispose of their waste.

Soil pollution is represented by buried nuclear wastes, chemical pollution and agricultural impacts. and for people’s health after contact with such soil or after eating products that were cultivated on the polluted territory. There is also a problem of uncontrolled dumpsites that stretch over several kilometers practically near every city of the world. Scientists have invented a lot of methods to clean polluted soil. Phytoremediation, aeration and dredging are among them.

Soil pollution is represented by nuclear waste disposal, chemical pollution and agricultural impact. As a result, Badlands appear, and there is a danger to public health after contact with such soil or after eating products that are grown in contaminated areas. There is also the problem of uncontrolled landfills that stretch for several kilometers near almost every city in the world. Scientists have invented many ways to clean up contaminated soil. Phytoremediation, aeration and work to remove the contaminated soil layer among them.

In recent years the number of environmental problems has increased greatly. One of the most dangerous problems for our planet is global warming which means that most climates all over the world are changing and getting warmer. It happens because we burn too much petrol resources, such as oil and coal, and the Earth heats up. This process can cause melting of the polar ice and the sea level rising in the future. If the climate changes there will be floods, heavy storms or severe droughts in different areas of the world. Cutting down on exhaust fumes from vehicles could help solve this serious problem.

Our planet is overpopulated, that’s why we are using up our natural resources - they are not endless. So the scientists have started looking for some alternate forms of energy such as water, wind, sunlight and even tides. These resources are clean, natural and unlimited. I'm glad that modern automobile industries make hybrids which use electric or solar energy instead of petrol. It would definitely help protect our environment from pollution.

There are different kinds of environmental pollution: air pollution, water pollution, land pollution. Sadly, not all human beings realize or admit that we are the ones who cause these problems and we should be the first to stop them and protect our environment. Because of the industrial revolution the air is polluted with awful chemicals; seas and oceans are poisoned with oil spills. Many rare species of flora and fauna are threatened with extinction.

We should be proud to live on our wonderful planet and understand that the consequences of pollution might be terrible and affect us and our children later. We should start recycling things made of glass, paper, plastic and aluminum. We should stop smoking and plant as many trees as we can because they can give us more oxygen. We need to drive less and use public transport in order to reduce fuel burning. We are responsible for the situation.

Environmental problems

In recent years, the number of environmental problems has increased dramatically. One of the most dangerous problems for our planet is global warming, which means climate change around the world and its warming. This is because we burn too many fuels like oil and coal and the Earth heats up. This process could lead to melting polar ice and rising sea levels in the future. If the climate changes, there will be floods, severe storms or severe droughts in different parts of the world. Reduction of exhaust gases Vehicle could help to resolve this serious problem.

Our planet is overpopulated, so we use up our natural resources to the limit - they are not endless. So scientists began looking for alternative forms of energy such as water, wind, sunlight and even tides. These springs are pure, natural and endless. I'm glad the modern automotive industry is making hybrids that use electric or solar power instead of gasoline. This will definitely help protect our environment from pollution.

Exists different types environmental pollution: pollution of air, water and soil. Unfortunately, not all people realize or admit that it is we who create these problems, and we must be the first to stop them and protect our environment. Due to the industrial revolution, the air is polluted with terrible chemicals; the seas and oceans are poisoned by oil spills. Many rare species of flora and fauna are threatened with extinction.

We need to be proud that we live on our wonderful planet, and we need to understand that the consequences of pollution can be dire and affect us and our children later. We need to recycle glass, paper, plastic and aluminum products. We need to quit smoking and plant as many trees as possible so that they produce more oxygen for us. We must drive less and try to use public transportation to reduce the amount of fuel we burn. We are responsible for the situation.
