Question

Which of the following are causes of increasing pollution in cities?

• B. Overuse of vehicles
• C. Factories
• D. Planting trees

Answer 1

Answer: (A), (B), (C)

The correct options are
A Increase in population
B Overuse of vehicles
C Factories

$\bullet$ Increase in population is one major cause of pollution as it leads to excess use of resources and degradation of the environment such as cutting of trees, etc.
$\bullet$ Overuse of vehicles is also a reason as the smoke from vehicles pollutes the air and also these vehicles cause noise pollution.
$\bullet$ Similarily, the factories also pollute the air from the smoke they emit and also pollute the water by dumping waste materials into it.
