finite and renewable resources

• natural resources:

  • without human input
  • can be replaced by synthetic products
  • rubber can be extracted from sap of tree
  • manmade polymers can be made to replace rubber
  • agriculture provides conditions where natural resources can be enchanced for needs e.g fertilisers
• • Haber process allowed fertilisers to be produced from nitrogen in air
  • allowed synthetic fertilisers to be produced
  • allowed for widespread intensive farming
  • more food produced to support growing population
