Sustainable Development
Task 3.
What is Sustainable Development?
 The term "sustainable development"
emerged from the 1987 report of the UN's
World Commission on Environment and
Development
 The term has no legal definition. It means
simply "...to meet the needs of the present
without compromising the ability of
future generations to meet their own
needs,"
Population: In the next 10 years about 800
million people will be added to the global
population.
Food
Food production will have to nearly double to
meet the demands of this growth
Cities : At the beginning of the last century, only one
in 10 people lived in cities. Now it's close to 50% and it's still rising.
Pollution: Half the world's urban residents are
exposed to potentially harmful amounts of sulphur
dioxide, ozone and particulate matter in "smogs".
Biodiversity: Every year thousands of species
become extinct due to human activity and the loss of
natural habitat.
Forestry: Logging and land conversion to
accommodate human demand has shrunk the
world's forests by half.
Wetlands: Urban and industrial development
claimed half the world's wetlands in the 20th
Century
Water: Within 25 years, half the world's population
could have trouble finding enough fresh water for
drinking and irrigation.
Refugees: By 2025, the number of refugees
fleeing floods and natural disasters could
quadruple to 100 million.
Energy: For global development to be both fair and
sustainable, the rich world may need to cut energy
and resource use by 90% by 2050.
Transport: In the last 20 years there has been a two-thirds
increase in global household energy use, road vehicle fleets
have doubled, and air traffic has quadrupled.
Waste: As population, consumption and wealth increase, so
does the quantity of waste we produce. The rich countries of
the OECD produce an annual total of almost two tonnes of
waste for every person.
Facts
 It would take 1.2 Earths to regenerate
resources at the rate we're using them.
 Humans started to exceed nature's ability to
regenerate from the mid-1980s onwards.
 In 1961 humans were using 70% of the
capacity of the global biosphere. By 1999, that
had risen to 120%.
What can you do to address the
problems of Sustainability?
 Fairtrade : anything with a Fairtrade label ensures that those who
produce the goods are given enough money to sustain production,
invest in development and support their families and the community.
Buy products with this label and you help sustain poorer communities.
 Organic food – reduction in pesticides, not only better for you but also
better for the environment
 Recycling – avoid putting waste in land fill sites which causes pollution,
most things can be recycled and turned into new products. E.g. putting
paper in a recycling bin means that it can be turned back into paper
and fewer trees need to be cut down, 9 plastic bottles will make a
fleece!.
 Saving water – water meters mean that the more you use the more you
pay ensuring that the additional money can go back into sustainable
development. Simple things to do, turn off the tap when your brushing
your teeth.
What is being done to try and
address Sustainable Development
 Generating Energy : wind power and solar power
can be used in homes to reduce our reliance on
gas and electricity.
 Travel – going on holiday by plane ensures that
we help poorer countries through tourism but the
pollution from planes is massive. Planting more
trees can help counteract these and additional
money on flights would enable this to happen. This
is called Carbon Ofsetting.
What is Deeside College Doing?
 Aiming to achieve Flintshire Fair trade status in the
current academic year
 Aiming to increase awareness of fair trade through
active involvement in fair trade fortnight, notice
boards, information leaflets etc
 Involved in an energy saving trial for vending
machines
 Encouraging recycling in café 6 and café talk and
refectory areas
 College prospectus & some leaflet on 70%
recycled paper
What is Deeside College Doing?
Measuring our environmental impact
Reducing that impact:Automatic lighting controls
New heating boilers
Use of solar energy
Reducing waste & recycling
Use of recycled materials
Training staff & students
Advising and supporting the local community
Task
 In groups identify the following:
 1. What do you do which is having a
negative affect on the environment?
 2. What do you do which is having a positive
affect on the environment?
 3. What would you class as the 3 most
important things you need to change?
 4. What could Deeside College do to
improve sustainability?
