Answers
Hey mate, here's your answer::
Resources include food, water, basic amenities, electricity etc. ... Moreover, the resources are very limited as all resources are not renewable. Also, the population is growing at an exponential rate. So, to cater the needs of growing population and future generations, resources should be used judiciously by us.
Electricity is very important for our generation, it will be important for future generations as well. ... Electricity is primarily generated with the help of electrochemical generators. Power Generators run on the process of nuclear fission or combustion of fuel like coal, wood etc.
Natural resources are limited in quantity, especially the non-renewable ones, which once consumed, cannot be regenerated. The reserves of fossil fuels such as coal are rapidly dwindling owing to massive consumption the world over.
