THE USE OF NATURAL RESOURCES
RENEWABLE SOURCES
fundamental
their existence and renewal
depend on rational use
land and forests
inexhaustible resources
sun light
wind
salty water
Fertile soil
very important
agriculture
livestock
can by used up
overexploitation
basis of the global food supply
the land is getting less fertile
disappearance of land
desertification
loss of soil
excessive use
pesticides
fertilisers
inappropriate crops
Forests
forest fires
thousands of hectares disappeared
they cannot be recovered
expose ground to weather conditions
abusive exploitation
equatorial and tropical forests
it is threatened
an important source
resources
wood
absorption of CO2
industrial processes
everyday activities
generation of oxygen
maintain biodiversity
animal
plants
recreational areas
NON-RENEWABLE SOURCES
hydrocarbons or mining resources
development
industrial
economic
high global population
consumerism
great demand of products
all the Earth is ripe for
exploration
exploitation
energy production
greatest level of oil resources
it may lead to
non-renewable resources being used up
they mustn't be wasted
produce energy that we need
find alternatives
THE DEMAND FOR WATER
Fresh water
very threatened resource
the only alternative
desalination
expensive for many countries
necessary for live and exist
serious dangers
aquifers are
polluted
overexploited
consumption in developed countries.
The supply of our planet
renewable
scarce
availability of drinking water
for people and animals
not depend
the country being dry or wet
depend
the level of development
equatorial climate
a large amount of rainfall
there aren't
sewerage systems
water distribution network
Central Africa
India
China
Central America
South America
in most advanced countries
they don't worry
about the scarcity of water
that is a renewable good
must be conserved
consumption
domestic
inadequate watering systems in farming
the largest consumption of fresh water
recreational spaces
amusement parks, golf...
basis of the whole system
natural resources
their conversion into goods
free
economic
great changes
economic activities
production systems
