THE USE OF NATURAL RESOURCES
RENEWABLE RESOURCES
Fertile soil
Agriculture and livestock form
Basis of the global food supply & overexploitation
Excesive use of
Pesticides, fertilisers...
Make soil less fertile
Make land disappear altogether
Forests
Essential to the absorption of CO2
By industrial processes & everyday activities
Important source of resources
Necessary to
Maintain plant and animal biodiversity
Generate oxygen
Natural lungs -> recreational areas.
Renewable resources (with inexhaustible resources)
Fundamental
Their existen/renewal depen on ratonal use
Logging and forest fires
Expose the ground to weather conditions
Causes
Uprooting
Displacement
Soil erosion
Rich soil disappear every year
Can't be recovered
Most threatened renewable resources
Because of abusive exploitation
Equatorial forests
Tropical forests
NON-RENEWABLE RESOURCES
Industrial and economic development
High global population
Lifestyle "consumerism"
Depend on nonrenewable resources
Or mining resources
Resources must not be wasted
Essential that we find alternatives
Produce energy we need
THE DEMAND FOR WATER
Fresh water is renewable
Scarce supply on our planet
Most threatened resources
No alternative
For life to exist
Pollution and overexploitation of aquifers
Serious dangers
Availability of drinking water
Depends on its level of development
Countries in Central Africa
Greatest amount of rainfall
Not have
Sewerage system
Water distribution network
India, China, Central America and South America
Over the last few years
E.a. & production systems changed
But the basis of system
Are natural resources and their conversion into goods
(free or economic)
