Frequently Asked Questions
What is the difference between renewable and non-renewable resources?
Renewable resources can be replenished naturally in a short time (e.g., solar energy), while non-renewable resources are limited in supply and take millions of years to form (e.g., coal and petroleum).
Why is resource conservation important?
Resource conservation is important because most natural resources are limited in quantity. Overuse can lead to their exhaustion, threatening human survival and ecological balance.
What are biotic and abiotic resources?
Biotic resources are derived from the biosphere and have life, such as forests and wildlife. Abiotic resources are composed of non-living things, such as land, water, and minerals.
