Definition of water pollution : is the contamination of water bodies ,such as lakes, aquifers ,groundwater ,oceans ,etc .Water pollution occurs when pollutants are directly and indirectly discharged into water bodies without adequate treatment to remove harmful compounds .
Suggestion:
* Water pollution is an extreme problem on a global scale which people are having to cope with on an increasingly regular basis.
- Causes : Water is polluted by a variety of reasons. Firstly, the amount of industrial and domestic sewage results in the destruction of water resources. There are many manufactures are constructed along rivers or seas so that their wastes are being dumped directly to our water. Secondly, a lack of filtering system also a main cause of this issue. Because of an expensive purifying infrastructure system, most factories avoid building one.
- Solutions : However, water pollution can be solved by two possible solutions. Governments have a strong responsible to raise the awareness of public about protecting the water environment. Mass media could be used as a method to educate people about how water is important to our society. In addition, factories need to be encouraged to build the filtering system. They could ask for supporting investment from governments or some environmental organizations to create their own effective one.
* In conclusion, water resources are at risk because of sewage come from both industries and domestic and also a lack of purifying system. However, the attitude of citizens and producers could reduce the serious of the problem.

In my city – Ha Noi – has a problem very important. It is air pollution. Air pollution includes contaminants found in the atmosphere. These dangerous substances can be either in the form of gases or particles. There are so much industrial factories in city, there are many vehicles in streets, them released smoke into the atmosphere. And more, forest has being destroy, the atmosphere more and more polluted. The effects of air pollution are diverse and numerous. Air pollution can have serious consequences for the health of human beings, and also severely affects natural ecosystems.

Humans are today exposed to air pollution of all kinds, and affected by the harmful effects of the pollutants in the air they breathe. There are many causes of air pollution. One of the causes is vehicular traffic. Smoke generated by factories is also let out into the air. The burning of fossil fuels like coal also leads to harmful smoke.

The high levels of air pollution cause respiratory and cardiac problems, and affect other parts of the human body. It also causes other diseases like cancer. Millions of people around the world die each year due to air pollution.

All terrestrial life forms need air to breathe. We breathe in oxygen from the air and breathe out carbon dioxide. Air pollution is the phenomenon of harmful compounds in the form of gases and fine particles being let into the air thus polluting it.

Humans suffer from various respiratory and cardiac conditions due to air pollution. Air pollution also causes various diseases, including cancer, affecting other organs of the body.

Vehicular traffic is one of the causes of air pollution. The combustion of the automobile fuel, whether it is diesel or petrol, that powers a vehicle, leads to the release of poisonous gases released through the exhaust of the vehicle. In factories too when production processes are carried out, smoke is generated that is then released into the air leading to pollution. Smoke is also caused due to the burning of fuels like coal. Construction activity also causes air pollution.

Humans are today exposed to air pollution of all kinds. They are thus affected by the harmful effects of pollutants in the air they breathe. There are many causes of air pollution. One of the major causes of air pollution is vehicular traffic. Cars, buses, trucks, motorbikes, scooters and rickshaws are run on fuel. Automobile fuel combustion leads to the exhaust of poisonous compounds that include noxious gases as also particulate matter. The harmful gases that are part of exhaust fumes include hydrocarbons, nitrogen oxides, carbon monoxide and sulfur dioxide.

Factories also contribute to air pollution. The poisonous smoke and fumes generated by factories are released into the air thus polluting the air.

Similarly, the burning of fossil fuels such as coal, as also the burning of wood for cooking, and of farm wastes lead to harmful smoke polluting the air. The burning of garbage also creates harmful smoke.

Pollution of the air affects the air that humans and all other life forms breathe. People around the world are suffering from respiratory and cardiac problems, and diseases such as cancer affecting other organs of the body too. Millions of people die each year around the world due to air pollution.

Air pollution refers to the phenomenon of harmful compounds in the form of gases and fine particles being released into the air thus polluting it. If the air is polluted we cannot breathe fresh and clean air. This affects the lives of humans and all other life forms adversely. Humans suffer from various respiratory and cardiac conditions due to air pollution. Air pollution also causes diseases affecting other organs of the body. It also causes cancer. Millions of people around the world die to air pollution-related diseases each year.

Air pollution is caused by a number of factors. Vehicular traffic is one of the causes of air pollution. When vehicles ply on the roads, the combustion of the automobile fuel, whether it is diesel or petrol, leads to the creation of poisonous gases that are released through the exhausts of the vehicles. These gases, in the form of smoke and fumes, pollute the air severely. Various alternative fuels such as compressed natural gas as automobile fuel are being used now-a-days. Battery operated vehicles are also being run.

Factories also contribute to air pollution in a big way. When various production processes are carried out in factories, they release smoke and fumes. These are then released into the air. We see black smoke emanating from chimneys or exhaust towers of factories.

Smoke is also caused due to the burning of fossil fuels like coal. The burning of farm wastes and other garbage, as also construction activity also lead to air pollution.

Humans are today exposed to air pollution of all kinds. They are thus affected by the harmful effects of pollutants in the air they breathe. There are many causes of air pollution.

Vehicular exhausts cause air pollution

One of the major causes of air pollution is vehicular traffic. Vehicles of all kinds have multiplied across the country. Today traffic congestion on roads is very common. During peak and rush hours the traffic snarls are difficult to cope with for motorists and pedestrians. Commuting has therefore become difficult. Vehicles whether they are cars, buses, trucks, motorbikes, scooters or rickshaws are run on fuel. There is a process of fuel combustion that leads to the exhaust of poisonous compounds. It includes noxious gases and particulate matter. The harmful gases include hydrocarbons, nitrogen oxides, carbon monoxide and sulfur dioxide.

There are many causes of air pollution

Factories also contribute to air pollution. The smoke generated by factories is let out into the air thus polluting the air that we breathe. Similarly, the burning of fossil fuels such as coal, as also the burning of wood for cooking, and of farm wastes lead to harmful smoke. Production of electricity is also mostly through the process of burning non-renewable fossil fuels that leave dangerous smoke in the air. The burning of garbage also creates harmful smoke. Construction activity also creates particulate matter that pollutes air.

Air pollution affects us adversely

Today we are witnessing high levels of air pollution that affect the health of man and other creatures. People around the world are suffering from respiratory and cardiac problems, and various other diseases affecting other organs of the body. Air pollution also causes cancer. Millions of people around the world die each year due to air pollution.

The gases that cause air pollution are also greenhouse gases, and have caused global warming and climate change that affect the Earth and its ecology.

Pollution is the mixing of some harmful or poisonous materials into the natural resources available on the earth. It affects the ordinary living of the living things on this planet by disturbing the natural life cycle. Pollution can be of many types like noise pollution, air pollution, soil pollution, water pollution, etc. Air pollution is increasing day by day because of the growing number of automobiles, release of poisonous gases, smoke from industrial companies, finely dissolved solids, liquid aerosols, etc in the atmosphere. The air we breathe every moment causes several lungs disorders.

In this way soil and water pollution is also cause by the mixing up of the sewage water (having germs, viruses, harmful chemicals, etc) in drinking water, some dangerous agrochemicals such as pesticides, fungicides, herbicides, organic compounds like ether, benzene, some radioactive materials including radium and thorium, solid wastes (industrial ashes, rubbish, garbage), etc. We need to follow all the control measures implemented by the government to check its harmful effects.

Environmental pollution is the condition when the natural cycle of our environment gets disturbed and harms us. Some harmful environmental contaminants created by us in the form of smoke, solid or liquid wastes get intermingled into the environment and pollute it. It is only human who can check the environmental pollution by limiting their bad activities. Each and every person here is responsible for the environmental pollution in indirect way. Unknowingly we all are creating problems and challenges to the environment.

Some bad chemical compositions which we use on daily basis get intermingled into the environment and disturb its natural functioning and natural processes which directly affect our health. Human beings are considered as the most intelligent living being on the earth however it never means that they should interfere with the nature’s law of ecological balance. Our environment and we, both are incomplete without the helps of each other. We should try our best to maintain the healthy environment in order to continue the natural processes easily.

Pollution has become a major environmental issue as it has created lots of health hazards to the people and animals of any age group. In the recent years the rate of pollution is increasing very sharply because of the industrialized waste material mixing out directly into the soil, air and water. However, in our country full attention is not getting paid to control it. It needs to be tackle seriously otherwise our future generations would suffer a lot.

Pollution is classified into many categories according to the natural resources getting affected such as air pollution, soil pollution, water pollution, noise pollution, etc. Rate of pollution is increasing due to the selfishness of the human being to earn more money and to fulfill some unnecessary wishes. In the modern era where technological advancement is given more priority by the people, everyone has forgotten the real discipline of life.

Continuous and unnecessary cutting down of the forests, urbanization and large production through industrialization has involved as a huge causes of the pollution. Harmful and poisonous wastes created from such activities causes irreversible changes to the soil, air and water which ultimately push lives towards pain. This big social issue needs a public level social awareness programme to destroy by its root to get complete relief.

Environmental pollution is the biggest problem in the modern time we are facing. It affects us in all aspects such as socially, economically, physically, mentally and intellectually. Contamination of the natural environment gives birth to the lots of diseases which make human beings weak mentally and physically. Many of us are not well aware of the pollution even they do not know how they are creating problems to the environment and polluting it. This problem is becoming worse day by day because of the new technologies growth and development. Many new companies are opening in the industry and do more to grow their business in the competitive field.

Environmental pollution is not the problem only one country however it is the issue of whole world, so it needs effort by all of us together to correct it. If it is not taken under control, it may affect the whole universe to a great extent in the future. Environmental pollution is getting big by increasing level of pollution of water, air, sound and land. Increasing in the number of vehicles on the roads causes air pollution, increasing in the number of factories causes water pollution and land pollution. So, it needs limitation over all the causes of the environmental pollution.

The meaning of word pollution means to make things dirty. Accordingly the pollution of natural resources causes imbalance in the ecosystem. Currently we have been fatally surrounded by the major issue of environmental pollution. Pollution is the addition of any foreign or poisonous substances into the environment at very fast rate than the environment natural accommodation. The main causes of this social devil are the industrialization, deforestation and urbanization, the by-products of which causes contamination to the natural resources used by the living things on the earth as a routine of normal life.

Air pollution, water pollution and soil pollution are the most dangerous forms of pollution causing direct heath disorders to the human beings. We have no safe water to drink, pure air to inhale and pollution free land to crop. This widely spreading pollution need to be taken under control for the healthy survival of life on the planet in future. Different types of pollutants which are disturbing our natural ecosystem are gases (NO, SO2, CO2, CO, NO2), halogens (iodine, chlorine, bromine), deposited matters (dust, smog, grit), agrochemicals (insecticide, pesticides, herbicides), noise, photochemical oxidants (photochemical smog, peroxyacetyl nitrate, ozone, nitrogen oxides), organic compounds from industries (acetic acid, benzene, ether), radioactive materials (radium, thorium), some solid wastes (ash, garbage), etc.

Pollution is the big side effect of the industrialized societies of the modern world where industrial development and green house effect have adversely affected the ecosystem. Life supporting systems are speedily getting converted into the life destroying system because of the industrialization. Human greediness and misuse of freeness of doing anything lead them towards serious degradation and mismanagement of resources.

Earth is considered as the only planet suitable for the life existence in the whole universe. It gives us everything like air, water, land, plants, and sky for the healthy survival of the life. We cannot live here in the absence of all the basic components of life. In any case if the serious pollution problems occur, it causes hazardous to the life. Increasing number of vehicles on the roads and increasing demands of the usage of the petrol and diesel increases the risk of air pollution as petrol and diesel spread heavy amount of poisonous gases in the environment such as carbon monoxide, sulphur-dioxide, hydrocarbons, and many more gases are polluting the air. Now-a-days, a major threat to the life is due to the development of nuclear sciences.

The polluted air we breathe goes to our whole body and affect all the systems especially respiratory functions. It becomes the reason of origin of many diseases like cancer, respiratory problems, lungs disorders, bronchitis, asthma and many more. The increasing competitions of the nuclear experiments all over the world are creating the big threat of atmospheric balance destruction as this process releases lots of harmful chemicals, poisonous gases, and dust into the air which falls back again to the earth through acid rains and harms the growth of crops and life. This acid rain causes various harmful diseases to the human fraternity worldwide. Water pollution is increasing because of the direct drainage of industrial liquid wastes into the water of ocean, lakes, rivers, ponds and other water bodies. This water is used by the farmers in growing crops which we eat and disturb our physiological functioning.

Pollution has become the most serious issue as everyone is facing lots of health hazards in their daily life. Various types of pollutants from the industrial garbage and other activities are contaminating our natural resources like air, water, soil, etc. After being mixing into the soil, air and water, they are directly affecting the human being and animal body system and causing variety of lethal ailments to health. Noise pollution is affecting the listening system in the body as well as causing disturbance to the memory.

The rate of pollution in the cities is higher than the villages because of the vehicles transportation. Fumes arise from the running vehicles, factories and other industries are affecting the clean air of cities which is not fit for the breathing. Soiled water from the big sewage system, other garbage from the households, by-products from the factories and industries are directly mixing to the rivers, lake and oceans. Most of the solid wastes, garbage and other unused things are thrown away by the people on the land which cause soil pollution and affect the crop production. Most of the people in the cities spread noise pollution to a great extent during their birthday, marriage or other occasions just for their short time happiness. All the roads in the cities become full of traffic all through the day because of the increasing number of vehicles which are the reason of both air pollution and noise pollution.

Ultimately all the man made technological advancement is the big reason of all types of pollution on the earth. So, no one other than human, who is digging a pit of pollution worldwide and creating a serious problem for the living things on the earth. The quality of life is worsening day by day as pollution acts as a devil which causes various health ailments like high blood pressure, kidney disorders, respiratory disease, cancer, epidemics, skin diseases, etc.

Environmental pollution is the big issue now for the whole human fraternity on this planet today. We are continuously adding impurities to the environment unknowingly through our bad and careless activities. Environmental pollution affects the natural processes and living of human being. When we play with the natural cycles of the environment which consists of air, earth, water, land, plants and animals, it creates big challenges to us and makes healthy life almost impossible. It hampers the existence of both human and nature together as both are the completeness to each other.

The biggest issue to the environmental problem is the removal of forests and urbanization on that place because of the increasing pollution. Decreasing number of the plants day by day increasing the amount of carbon dioxide gas in the environment as plants are the main sources of the carbon dioxide gas utilization. Thus the increasing level of this gas in the environment causes global warming (increased climate temperature due to emissions of greenhouse gases) which in turn causes lots of problems and brings environmental and social changes in direct and indirect ways. The warming effect on the climate causes glaciers to melt, seasonal problems, decreasing agricultural productivity and many more.

Continuous warming of the earth may cause earth a day as a boiling pan and desert whole earth would be covered with ocean water means permanent destruction to the mankind. For our good health we need fresh and pure air to inhale, unpolluted food to eat, no noise pollution and unpolluted water to drink however all are not possible now. That’s why everyone of us are wasting more money into the medicines by making round and round of the hospitals instead of spending money to good health activities like eating fruits, joining health club, etc. So, the environmental issue need to be solved on urgent basis by the effort of all of us.

In the modern world of technological advancement, pollution has become a serious environmental issue affecting the lives on earth. Some of the most important types of the pollution are air pollution, water pollution, soil pollution and noise pollution. All types of the pollution are undoubtedly affecting the whole environment and ecosystem thus the quality of life. Our naturally beautiful environment on the earth is deteriorating day by day just by the foolish habits of the human beings.

The main reasons of the air pollution are the heavy emissions of harmful and poisonous gases arise from the increasing number of vehicles, factories and open burning. In the crowd of betterment of life, everyone wants to have well resources for their easy daily routine but they do not think a little bit about their natural surroundings. Most of the air pollution is carried out by the public transportation on daily basis. Carbon dioxide and carbon monoxide are the toxic gases polluting the air and reducing the oxygen level in the environment.

Manufacturing factories are also the great contributor to the air pollution by meeting the growing demand of people. During the manufacturing process factories releases some toxic gases, heat and energy into the environment. Some other habits like open burning of household garbage, etc are also worsening the air quality. Air pollution causes respiratory disorders including lung cancer among human being and animals.

Water pollution is also a big issue directly affecting the marine life as they only depend on the nutrients found in the water for their survival. Gradual disappearance of the marine life would really affect the livelihood of human beings and animals. The reason of the water contamination is harmful wastes from factories, industries, sewage systems, farms, etc which are directly dumping into the main source of water like rivers, lakes and oceans. Drinking contaminated water causes serious health disorders to us.

Soil pollution is caused by the use of fertilizers, fungicides, herbicides, insecticides and other organic compounds. It indirectly affects our health as we eat eating materials produced in the soil. The source of noise pollution is the noise created from the heavy machinery, vehicles, radio, TV, speaker, etc which causes hearing problems and sometimes deafness. We should take care of our environment to maintain the natural ecosystem. It requires a joint effort from everyone to get control over the pollution so that we can get a healthy and unpolluted environment.

If I were the Minister of Natural Resources and Environment, the first thing i would do is recycle old paper, glass. Old paper can reuse to make paper bag.Glass can reuse to make the new glass.I would encourage people to ride the bicycle instead of motorbike or car, truck,....to reduce dust.

I would hold many meaningful activities for the environment such as: growing trees, taking care of public parks, protecting the rare animals and plants.
