PARAGRAPH ON AIR POLLUTION 1
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.
PARAGRAPH ON AIR POLLUTION 2
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.
PARAGRAPH ON AIR POLLUTION 3
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.
PARAGRAPH ON AIR POLLUTION 4
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.
PARAGRAPH ON AIR POLLUTION 5
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.

Life in the city, compared with life in the country
In my opinion, urban life or rural life has its own advantages and disadvantages.
First, living in the city we may enjoy those benefits.
- Communication and transportation systems are better. There are so many means of communication and transport that we can choose the ones we like best. We can get in touch with a friend or talk to him by phone without having to go out of home.
- Thanks to electricity network and running water, our material lives are more comfortable. Supermarkets, markets and shops are found everywhere and we can buy anything we need providing that we can afford it.
- Urban life provides us with all sorts of entertainments: televisions, radios, movies, theatres, concerts and famous recreation centers.
- Living in town we can improve our knowledge easily by attending any schools, universities or evening classes where experienced teachers and professors are ready to satisfy our thirst for knowledge.
Besides its advantages, urban life also has its disadvantages:
- Our health is in danger: pollution by factories and heavy traffic may cause serious diseases to all of us.
- Evil influence upon the young generation by obscene video films is inevitable.
- Violent deaths happen regularly in such a crowded city with all kinds of vehicles.
On the contrary, rural life seems ideal to all of us, especially to the old.
- We can enjoy fresh, cool air and behold beautiful landscapes in the country.
- How safe and delighted we are when we can sleep a sound sleep at any time of the day without being disturbed by sirens of cars or by deafening noises from manufacturing factories.
- Our social lives in the country are easier: we can eat the food and vegetables we grow, the chickens and goats we raise. The countrymen lead a very simple life and they are quick at mutual Giúp in any case.
Apart from these advantages, living in the country we may meet lots of difficulties too.
- Communication and transportation are obstructed by lack of means of transport or by floods in the rainy season.
- Our knowledge is limited by being short of mass media.
- Our social and physical lives are not as comfortable as those in town because of lack of electricity and medical care.
In a nutshell, our love for town life or country life depends on our outlook and age. As for me, I always prefer rural life to urban life.

I think live in the countryside better than the city! First, the air here is clean and fresh, it's good for your health. In the countryside is not crowded like in the city, we won't hear the sound of car horn, it's very peaceful and make you feel very relax! The food here can not tasty and delicous but it fresh and make you healthy. There are many folk games we can't play in the city like Mandarin square capturing, tug of war blind man's buff, dragon snake, and more! Everything is very cool. In general, live in the countryside is very good!
Essay on Water Pollution – Essay 2 (250 Words)
Introduction:
The consumption of water forms a large part of our physical health. Aside from this obvious fact, water is an important aspect of our ecosystem. However, for water to perform its various functions, it has to be kept pure as contaminated water would lead to adverse environmental and health consequences.
Water pollution is the introduction of foreign material into our water bodies like lakes, streams, rivers or groundwater. This introduction, 9 times out of 10 is usually a result of human interference. Through various activities, sometimes inadvertently, we pollute our ecosystem with toxic materials dumped into our water.
Causes of Water Pollution:
One of the most popular features of water is also the cause of water pollution. Water is a “Universal Solvent” which simply means that it can dissolve almost any substance. Consequently, it is also why toxic substance mixes with water effortlessly. These toxic materials could be from traceable sources such as factories, farms, sewage etc. They are sometimes less traceable sources such as pollution in the air.
Water Pollution Effect on our Environment:
The first organisms that come in contact with polluted water are creatures living in the water. The effect of water pollution on aquatic animals depends on the kind of material introduced into the water. In extreme cases, it can lead to death of aqua species. It can also lead to a serious disrupting of the food chain. Finally, water pollution can lead to serious diseases in humans such as cholera and hepatitis.
Preventive Measures:
While the obvious way to reduce or eliminate water pollution is to stop industrial waste, doing just that and nothing more would not be enough. Preventive measures such as reduction in plastic consumption, controlling leaks in cars, using fewer pesticides or efficient disposal of chemicals would help us go the extra mile.
I think life in the countryside has many good points. Firstly, people are friendly to each other. They are willing to help whenever someone gets into trouble. They are so outgoing that we can make friends with them easily. Secondly, life in the countryside is peaceful and simple. There aren’t many vehicles moving on the road as in the city. Thirdly, food is obviously fresher and cheaper. We can eat without worrying too much about food’s safety because vegetables are grown naturally. Finally, traditional activities are very interesting to take part in. In each region, there are its own activities attracting visitors. For these reasons, the countryside is the ideal place for me to live.
