Frequently Asked Questions
What is the difference between renewable and non-renewable resources?
Renewable resources can be replenished naturally in a short time (like solar energy), whereas non-renewable resources have limited stocks and take millions of years to form (like coal and petroleum).
Why is resource conservation important?
Resource conservation is important because most natural resources are limited in quantity. Overusing them can lead to exhaustion, endangering future generations and disrupting the ecological balance.
How can we contribute to sustainable development at home?
We can contribute by saving electricity, turning off taps when not in use, reducing plastic waste, recycling materials, and planting trees around our neighborhood.
