Resource exploitation: Water, Agriculture, Deforestation, Food & Urbanization

3. What does overpopulation mean?
 Overpopulation is when there are to many people for
the available ground and resources to support
everyone.

4. Resources:
 The Earth has a limited area where people can
live and also limited resources.
 The Earth also have limited carrying capacity- it is
the number of people an area can support on a
sustained basis given the available space, resources
and the prevailing technology.

5.  Our resources needs to be used on a sustained basis
for our population to keep on growing.
 Therefore sustainable development is the idee that a
community can develop and survive if the resources
to their disposal is used on such a manner to ensure
the survival of the community.

6. A few consequences of overpopulation:
 World population:
 Is currently more than 7 billion.
 80% of the worlds population is from less developed
countries.
 Population growth is high in these countries.
 Average growth of 1.5% per year.
 In economically developed countries the average
growth is 0.2% per year.
 Poor counties maintain much more people and very
little resources.

7. Water:
 The demand for water increases as the population
grows.
 One third of the worlds population live in counties
with medium to high levels of water shortages.

9. Agriculture:
 As the population increases, the availability of
agricultural land decreases.
 New agricultural land is not always avaliable.
 People need to plant more food on the available land.
 It is expensive and not always possible.

11. Deforestation:
 The Earth is losing its forests.
 Between 2000 and 2010 13 million hectar of forests
were destroyed.
 Forests are important for ecosystems, climate ect.

13. Food:
 Undernourished people in the word has increased
form 857 million in 2000 to 925 million in 2010.
 There are no shortages of food on Earth, distribution
and availability of food is the problem.

15. Urbanization:
 More and more people live in towns and cities.
 By 2030 75% of the worlds population will be
urbanized.
 Increasing urbanization goes coupled with
overpopulation and informal settlements without
the necessary infrastructure.
 Leads to the decrease in the standards of how
people live.
