Answer 1

Conserve energy - at home, at work, everywhere.
Look for the ENERGY STAR label when buying home or office equipment.
Carpool, use public transportation, bike, or walk whenever possible.
Follow gasoline refueling instructions for efficient vapor recovery, being careful not to spill fuel and always tightening your gas cap securely.
Consider purchasing portable gasoline containers labeled “spill-proof,” where available.
Keep car, boat, and other engines properly tuned.
Be sure your tires are properly inflated.
Use environmentally safe paints and cleaning products whenever possible.
Mulch or compost leaves and yard waste
.Consider using gas logs instead of wood

Prevention Of Air Pollution :
========================

We all know that we need a healthy and clean air for breathing . The task of cleaning up air and improving it's quality are not very difficult. For this we have to take some steps and use devices that are necessary and observe some restraints , Some Steps are as follows :-

♣ Household :
-----------------------

◆ Improved smokeless chulhas and efficient stroves should be used to burn fuels like Wood, Coal, kerosene in our villages and cities.

◆ We should shift to smokeless energy sources like LPG, biogas, solar energy and electrical energy.

◆ We should not burn paper, dry leaves, plastic bags and garbage.

◆ We should reduce the use of aerosols and sprays such as perfumes, deodorant sprays, cosmetics and other similar sprays in homes because their solid or liquid particles remain suspended in the air for long.

◆ Smoking should be avoided.

♣ Automobiles :
-------------------------

◆ Use of efficient internal combustion engines for complete combustion of fuels

◆ As far as possible lead free fuel such as Compressed Natural Gas (CNG); Should be used for running cars, buses, trucks etc.

◆ Catalytic converter is fitted in the exhaust pipes of the petrol driven vehicles. This converter converts the harmful exhaust gases- carbon monoxide (CO) and nitrogen dioxide (NO2) into harmful Carbon-dioxide (CO2) , nitrogen and water.

◆ The vehicles should be subjected to air pollution check regularly and strictly.

♣ Power Generation :
----------------------------------

There is a need for using the less polluting forms of power generation like solar energy, wind energy, Tidal and Geothermal energy and other forms of renewable energy.

♣ Industries :
---------------------------

◆ Tall Chimneys fitted with filters should be installed in factories, so that the air is not polluted much near the surface of the earth.

◆ Mills and Factories should run in the main city where there are lot of people but should be in secluded areas.Goverment is taking action against industrial units by not giving licences to operate in thickly populated areas.

♣ Use of Scrubbers :
----------------------

These are used to remove suspended particulate matter (SPM) from air emissions from factories. The SPM present in air emissions is removed by spraying a jet of water on air. Water thus wet the suspended particulate matter present in air and washes them away.

♣ Use of Electrosatic Precipitation :
--------------------------------------

This device is used if the SPM present in air emissions is in large amount. These are used in thermal power plants. In order to remove SPM, an electric current is passed through it. Because of this, the dust and smoke present in air get charged up and are thus attracted towards the electrodes and are collected.
