Here's a taster:

Resource availability
· Non-renewable resources: resources that there is
only a fixed amount of and are being used up.
They cannot be remade as they would take a long
time to reform i.e. oil.
· Sustainable resources: resources that can be
deliberately renewed and can be managed so that
they are usable now but will last into the future i.
e. wood.
· Renewable resources: resources that renew
themselves and do not need to be managed i.e.
wind power.…read more

Here's a taster:

Benefits and costs
· We need to assess resources, which we can do
by looking at the benefits and comparing
them to the costs.
· This is difficult as the costs and benefits can be
indirect and unintentional.
· These factors are important as convention
`cheap' oil is running out and we need
alternative energy to fill the gap between
supply and demand.…read more

Here's a taster:

`Haves' and `Have nots'
· Many countries that have a large quantity of valuable
natural resources are LEDCs and LLEDCs. They are less well
developed than countries without these resources.
· For example: Diamonds. The DRC is 177/179 on the UN
development table yet produces 21% of the world's
diamonds. Botswana also produces 21%, and is also low on
the UN development table; 126/179. The money made
from diamonds in these countries is not benefitting the
· The wealth is unevenly distributed in these countries. A
small number of the rich have done extremely well from
the diamonds that the people mine, yet the people haven't
seen the benefits. There is a considerable gap between the
rich and the poor.…read more
