Using resources sustainably
Humans use the Earth's resources for warmth, shelter, food and transport.
Natural resources, helped by agriculture, give food, timber, clothing and fuels; chemistry adds or replaces them with synthetic products.
- Finite: a fixed amount, used faster than it forms (crude oil, natural gas, coal, metal ores, limestone).
- Renewable: replaced as fast as it is used (timber from managed forests, cotton, wool).
- Sustainable development meets the needs of people today without stopping future generations from meeting theirs.
