Sustainability

• Sustainabilty refers to meeting the needs of the
  present without compromising the needs of the
  future.
• It is important to understand the various ways
  people interact with the environment and
  recognise that this interaction has consequences.
• Question What would have been the environmental
  impacts of Pre-European Maori compared with
  modern population settlement in New Zealand today?

5
What Should We Do?

• Whatever the cause, its clear that it will be
  difficult at best for earth to sustain its
  growing population. This is especially true if
  the population continues to increase, consumption
  levels remain high, and we fail to increase our
  available resources to meet basic human needs.
• What is done now will determine the quality of
  life, and even the survival of life, for future
  generations.

Possible

• Solutions

1) Controlling Population Growth

• One popular solution to the resource crunch and
  global population growth is simply to reduce the
  number of people on earth, usually by slowing the
  rate of growth.
• Family planning policies try to reduce the birth
  rate.
• Question What are the positives and negatives of
  the above policies? Try to name some specific
  family planning policies.

2) Reducing consumption

• There are not enough resources to go around at
  current levels of consumption.
• Many people believe that rich countries need to
  cut back on their consumerism and consumption
  levels.
• Question How can you as an individual cut back
  on your consumption? How can society at large cut
  back on consumption?

3) Redistribution

• Resources and income could be chanelled from
  those who are rich to those who are poor. This
  would require government intervention.
• One way to do this would be to use tax policy to
  increase the price of luxury goods, goods that
  use scarce resources, or products that have
  environmental consequences.
• Question What do you think of a global carbon
  tax?

10
4) Making the pie bigger

• Humans are very resourceful and constantly
  developing new technologies to find and make the
  most of available resources and hence, sustaining
  the growing population.
• An example is the 20th century Green
  Revolution. High yield crops were introduced to
  countries such as India.
• Genetically modified crops could increase yields
  why allowing plants to grow in more difficult
  environments with minimal water and fertiliser.
  Question what are the risks in this?
• Water desalinisation and improved public
  transport could also make a difference.

Case Study

• Asia Region

12
Introduction

• Monsoon Asia has about 60 of the worlds
  population living on just 14 of the worlds land
  area. It includes some of the most crowded places
  on Earth.
• Monsoon Asia includes the two most populated
  countries on our planet China (1.3 billion) and
  India (1 billion).
• Together these two countries account for 36 of
  the worlds total population.
• Task Complete a map of the Monsoon Asia
  countries.
