Using Earth's Resources
- Humans use earth's resources for warmth, shelter, food, and transport.
- Natural resources are supplemented by agriculture to produce fuels, clothing, and construction materials.
- Chemistry improves agricultural and industrial processes and replaces natural products with synthetic ones.
- Synthetic fertilizers, derived from ammonia, enhance crop productivity.
- Clothing has shifted from natural fibers to synthetic fibers like polyester, saving resources.
- Finite resources, such as fossil fuels and metals, are being depleted faster than they can be replaced.
- Renewable resources, like timber, can be replenished at the rate they are used.
- Data helps track resource usage and sustainability.
- Chemistry contributes to sustainable development by finding alternatives to finite resources.
- Bioplastics, made from corn starch and microorganisms, offer a renewable alternative to traditional plastics.
