- 4. Human use ofNatural Resources • Humans use natural resources to help meet their three basic needs. • The use of natural resources to meet these needs is in two forms, a)consumptive use and b)non-consumptive use.
- 5. Consumptive Use • Usinga natural resource so that the amount used no longer exists. • Each time that resource is used, its supply is reduced. • An example of consumptive use is hunting. – Once that animal is killed and removed from the wild, it no longer exists.
- 6. Non-consumptive Use • Usinga natural resource without reducing its supply. • An example of non-consumptive use is watching wildlife. –It is possible to enjoy the beauty of the wildlife without killing or removing it from the wild. –It is being used for enjoyment, not being consumed.
- 7. Human Impact onNatural Resources • Virtually all human activities impact on natural resources. • From the use of water to bath to the use of animals for food, natural resource use is unavoidable.
