					   Agenda 21

International Initiative
            Earth Summit
• Agenda 21 was established at the 1992
  United Nations Conference on
  Environment and Development in Rio de
  Janeiro, Brazil.
• Agenda 21 is a commitment to sustainable
  development, which was agreed by many
  of the world’s governments.
              Agenda 21
• Countries that have agreed to Agenda 21
  are encouraged to conserve and preserve
  their environments and natural resources
  at local and national level.
Agenda 21 tackles social and environmental
problems, including:
• air pollution
• deforestation
• biodiversity loss
• health
• overpopulation
• poverty
• energy consumption
• waste production
• transport.
     Sustainable development
• Sustainable development encourages the
  conservation and preservation of natural
  resources and of the environment.
• If sustainable development is to be
  successful we all have to change our
  attitudes to our current lifestyles and the
  impact they have on the environment.
 Conservation and preservation
• Conservation is the sustainable use and
  management of natural resources,
  including wildlife, water, air and earth
  deposits. The conservation of trees
  involves making sure that they are not
  used faster than they can be replaced.
• Conservationists say that development is
  necessary for a better future, but only if
  the changes are not wasteful.
 Conservation and preservation
• Preservation attempts to maintain in their
  present condition areas of the Earth that
  are so far untouched by humans.
• Many landscapes are being taken over by
  farming, industry, housing, tourism and
  other human developments, and we are
  losing many landscapes that are truly
  natural.
                   Energy
• Energy is needed for heating, electricity,
  manufacturing, construction and transportation.
• Fossil fuels (coal, oil and gas) are non-
  renewable. The average person in the UK uses
  35 times as much energy as someone in India.
• Renewable energy sources include solar power,
  wind power and hydroelectric power. Agenda 21
  requires countries to increase the proportion of
  energy supplied by renewable schemes that do
  not produce greenhouse gases, which may
  cause global warming.
                Transport
• Transport is damaging our environment,
  producing pollutants that lead to acid rain,
  poor air quality and global warming.
• Governments need to control the rate of
  traffic growth and improve the
  performance of vehicles.
• People need to be encouraged to become
  less dependent on cars and increase their
  use of public transport.
                    Waste
• The more waste we produce the more we have
  to dispose. Sustainable waste management
  encourages the generation of less waste, the re-
  use of consumables and the recycling of waste
  that is produced.
• Waste includes paper, plastics, glass, metals,
  foods, chemicals, oils, bricks and wood.
• The UK aims to reduce, re-use, recycle and
  recover waste.
