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
- 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
