Why does the author give the example of land use averages at the end of the paragraph?
Planet Earth provides all the resources we need to live –
air to breathe, water to drink, soil to grow crops, fuels to
burn, and materials, like metals, to build things. Most of
the Earth’s resources are constantly being made on
Earth. Some are made quickly like wood when trees
grow, or freshwater when rain falls. Some take
thousands of years to form, like soil. And some are
limited, like land. Land is a very basic but essential
resource, because it is needed to grow plants, which are
used for food, fuel, and materials. The world’s land is
not divided fairly at the moment – people in
industrialised countries use far more than their fair share
to support their lifestyle. If people in developing
countries like India and China start consuming as much
fuel and food, the world will not be able to support us all.
Currently, the sustainable land use average per person
is 1.8 hectares. However, if the 5 billion people in the
developing world used as much land as the 1.5 billion in
the industrialised world (5.4 hectares per person), we
would need three Earths to live on.
