Question

number of cars road and pollution explanation

Answer 1

Answer:

Now a days having a car has become too common as life standards has increased and no one are looking for money.

Every one look forward for comforts.

Hence a family sometimes may have more than one car.

This increases the combustion of fossil fuels like petroleum and diesel.

Thus green house gases are increased in the environment resulting in greenhouse effect, air pollution and sometimes depleting ozone layer.
