Question : 15
Total: 26
"Crude oil reserves are limited all over the world. If people continue to extract it at the present rate, the reserves would last only 35 - 40 years more" Explain any three ways to solve this problem.
Solution:  
Crude oil is a non-renewable resource of energy. It takes millions of years for the formation of this fuel, hence it must be used judiciously. This type of fuel is being used at a faster rate than they are being produced. This causes depletion and scarcity of crude oil.
Steps which can be under taken to conserve this non-renewable source of energy are:
(i) Use of public transport like buses and trains instead of self-owned vehicles will help to conserve petroleum. Carpooling will reduce the consumption of fuel, thus scarcity will be better dealt with.
(ii) Use of cycles wherever possible instead of using motorbikes or cars.
(iii) Waxing floors with beeswax instead of petroleum based commercial wax can also be beneficial.
