Answer 2

Answer:

Air Pollution

When undesirable particles or some harmful gases mix with air, it is called air pollution. Large particles of smoke coming out from chimneys of factories and vehicles cause pollution. When fuels like petrol, diesel or coal are burnt, they produce very harmful gases. These gases may damage our respiratory system and cause skin disorders. So, it is important to use fuels like LPG and CNG to make our environment pollution free. Along with this, we should plant more trees to maintain oxygen-carbon dioxide balance on the earth.
