uses

• humans use the earth's resources to provide:

  • warmth
  • shelter
  • food
  • transport
• Natural resources, supplemented by agriculture, provide

  • food
  • timber
  • clothing (cotton)
  • fuels (trees)
• chemistry has replaced natural resources with a synthetic alternative

  e.g. rubber

  natural = tree Sap / synthetic = crude oil
• some resources from the earth/oceans/atmosphere are finite - e.g. fossil fuels, metals

  this means they are being used up faster than they are being replenished
• some resources are renewable, e.g. wood

  this means that they are being replenished as they are being used
• sustainable development:

  development that meets the needs of current generations without compromising the ability of future generations to meet their own needs

  the may be seen through clothing, natural = cotton but synthetic = polyester
