AIR POLLUTION 

Air pollution is defined as the introduction of contaminants/pollutants into the atmosphere, such as toxic gases, dust, fumes, or smoke. It can happen as a result of human activity or natural events like volcanic eruptions, pollen distribution, and forest fires. It pollutes the air in the surrounding area. Pollutants in the air spread quickly, causing harm to all living things.

Causes of air pollution 

There are numerous elements that contribute to air pollution. Let's take a look at a couple of them.

To get wood, we had to cut down trees. Wood is used to build houses, make paper, and as a fuel source. Deforestation is the systematic removal of trees on a vast scale. As a result, there are fewer trees in the environment. Due to which there is less oxygen accessible to living creatures. Hence, the amount of carbon dioxide in the atmosphere rises, resulting in air pollution.

• Vehicles and industry emit harmful gases from the combustion of fuels such as coal, gasoline, and diesel.

• Factory smoke releases toxic pollutants into the atmosphere, including carbon dioxide.

• Another source of pollution is the burning of firecrackers, rubbish, and stubble.

• Smoke is sent into the atmosphere by volcanic eruptions and forest fires. Furthermore, it pollutes the atmosphere.

Effects of air pollution 

• Air pollution has a negative impact on our respiratory system. Asthma and other respiratory issues are possible side effects. It can irritate the eyes as well.

• Sometimes the harmful gases present in the air can mix with rain and form acid rain. This rain harms plants and even buildings that it falls on

• Some of the pollutants are very dangerous for health. They can cause heart disease and can affect the brain, liver, and kidneys. 

• When toxic gases in the air combine with rain to generate acid rain, it is known as acid rain. Plants and even structures are harmed by this downpour.

• Some of the contaminants are quite harmful to one's health. They can harm the brain, liver, and kidneys, as well as induce heart disease.

Prevention of air pollution 

• Vehicle pollution inspections must be performed on a regular basis.

• Factories must have towering chimneys to ensure that dangerous gases are emitted far from the air we breathe.

• All waste burning shall be prohibited.

• Trees emit oxygen and aid in the purification of the air. More trees should be planted in the community to provide oxygen and aid in air cleaning.

PROTECTING THE ENVIRONMENT 

Planting more trees will help to protect the environment. Afforestation is the process of planting trees in regions that have been deforested or have fewer trees. It aids in the preservation of animal habitat. It also helps to keep soil from eroding. Preserving our present woods and preventing their destruction will also aid in environmental protection.

Plastic bags should not be thrown down drains because they clog them and prevent unclean water from flowing.

Electronic garbage, such as TVs, batteries, cell phones, and laptops, must not be dumped. Electronic waste items are particularly dangerous to the environment.

Wet waste, such as fruits and vegetable peels, and residual food products should be disposed of separately from dry waste, such as papers, plastics, and bottles.
