Question

We must use substances like petrol, diesel sparingly and very judiciously. Give reason.

Answer 1

If we overuse petrol, diesel there is a probability that they will be exhausted in the near future because their reserves are limited on earth and are non-renewable resources. Also, the burning of these fuels causes air pollution or produces gases (like carbon dioxide) which are responsible for global warming.

Due to these reasons, we must use substances like petrol, diesel sparingly and judiciously.
