Air pollution is a change in the composition of air. Mainly due to smoke, dust, vapors or toxic gases that cause climate change, adversely affect human health or may damage the natural environment of many other species.

Air pollution is the cause of the risk of stroke, neurasthenia, cardiovascular disease, cancer, and a range of respiratory diseases such as asthma, pneumonia, even lung cancer is increasing. .

Air pollution is divided into two types, including outdoor air pollution and indoor air pollution. In particular, outdoor air pollution is a major factor causing serious impacts on the environment and human health in developed and developing countries. The cause of pollution comes from various sources such as traffic emissions, industrial plants, from agricultural production and some natural causes such as forest fires, desert dust, volcanoes.

Besides, we also face indoor air pollution. Pollution sources include cigarette smoke, charcoal, wood, chemicals in paint or cleaning products, air-conditioning gases and some substances in construction materials.

Nowadays, the development of human world causes causes many bad effects to the environment. We throw garbage everywhere, exploit too much natural resources or contaminate the air. Therefore, our environment is being seriously polluted and we need to protect it from now. First of all, we should reduce, reuse and recycle. Instead of using plastic bags, we can use leaves to wrap food. We can recycle plastic bottles, cans, paper to reduce garbage. Using public transports and decreasing the number of motorbikes and cars are also good ways to reduce carbonic in the air. Besides, we should purify contaminated lakes or rivers in order to lessen the pollution in the water.Last but not least, the gorvernment should propagandize about protecting the environment to everybody so that they can aware of it. Especially, we need to punish people who contaminate the environment with great severity. In conclusion, the Earth is our home so protecting it is everyone's responsibility.

Ngày nay, sự phát triển của thế giới loài người gây ra nhiều tác động xấu đến môi trường. Chúng ta vứt rác khắp nơi, khai thác quá nhiều tài nguyên thiên nhiên hoặc làm ô nhiễm không khí. Do đó, môi trường của chúng ta đang bị ô nhiễm nghiêm trọng và chúng ta cần bảo vệ nó từ bây giờ. Trước hết, chúng ta nên giảm thiểu, tái sử dụng và tái chế. Thay vì sử dụng túi nhựa, chúng ta có thể sử dụng lá để bọc thức ăn. Chúng ta có thể tái chế chai nhựa, lon, giấy để giảm rác. Sử dụng vận tải công cộng và giảm số lượng xe máy và ô tô cũng là những cách tốt để giảm lượng carbon trong không khí. Bên cạnh đó, chúng ta nên làm sạch các hồ hoặc sông bị ô nhiễm để giảm bớt ô nhiễm trong nước. Nhanh chóng nhưng không kém phần quan trọng, công việc bảo vệ nên tuyên truyền về việc bảo vệ môi trường cho mọi người để họ có thể nhận ra điều đó. Đặc biệt, chúng ta cần trừng phạt những người làm ô nhiễm môi trường với mức độ nghiêm trọng. Tóm lại, Trái đất là ngôi nhà của chúng ta nên bảo vệ nó là trách nhiệm của mọi người

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.

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.
