Renewable resources can be quickly replenished by nature (e.g., solar energy), whereas non-renewable resources have limited stocks and take millions of years to form (e.g., coal and petroleum).
Why is resource conservation important for us?
Resource conservation is important because most natural resources are limited in quantity. If we overuse them without care, they will exhaust, threatening the survival of future generations.
