INTRODUCTION
When Harmful Substances Contaminate the Environment it is Called Pollution.
Pollution refers to the very bad condition of environment in terms of quantity and quality .
There are Four types of Pollution• Air Pollution• Water Pollution• Noise Pollution• Land Pollution

HOW TO REDUCE VEHICULAR POLLUTION
Plant more trees along busy roads
Choose low-polluting models of vehicles
Use CNG
Use carpool and public transport or bicycles if it is a
short distance

CONCLUSION1. Pollution is caused mainly because of humans
and natural disasters.2. The main cause of air pollution are
vehicles(approximately 72% contribution.) 3. We should use public transport or low – polluting
vehicles to reduce air pollution. 4. The most fuel efficient car is Tata Indica eV2
followed closely by Tata Nano 2012.
