Natural resources → resources supplied by nature

  • Air, water, soil, forest, wildlife → renewable natural resources
    • Can be replaced in the ecosystem by natural cycles → as long as humans do not overuse them

→ on other hand → natural resources like fossil fuels → take millions of years to form naturally

  • Since formation takes millions of years → cannot be replaced quickly enough
    • Called non renewable natural resources

Human beings → continually using and depleting earths natural resources.

  • Upsets balance of nature + causes lasting damage to env.
  • Env. Damage caused → largely irreversible.
    • Thus human activities → may be carefully planned + monitored → preserve + conserve env for future
  • These activities → interrupt food chains and food webs in ecosystem
  • Through altering food chains and food webs → humans can have negative impact on habitats
