Achieving Sustainability
Brundtland commission (pg287)
What and when?
Rio Commission
Where and when?
Issues raised:
Agenda 21
2002 -
What were the targets made at each summit and how have the UK put these into action?
Sustainability of current exploitation and strategies to increase sustainability
Biotic resources
Habitat destruction
Water Resources
Current exploitation
Freshwater supplies
Extinctions
Back ground ratesHuman causes Locations rapid extinctions –
Maintaining biodiversity

Reducing Wastage of Water

Physical Resources: minerals, rocks aggregates
and minerals
Resource wastage and unnecessary use
Difficulties in recycling
Availability of high-grade ores
Strategies to increase recycling of physical
resources
Development of new technologies
Energy (pg 293)
Are we running out of fossil fuels?
What techniques are increasing fossil fuel
recovery?
How do these techniques explain the difference
between each resource and its reserves?
How is current energy use restricted? (pollution
and habitat damage concerns)
How do current patterns of consumption,
inequality and expected future increases:
Create pollution (page 296)
Affect LEDCS (page 299)
Climate Change – Fact or fiction?
Evaluate the conflicting evidence surrounding climate change
Do you think climate change is occurring? What is causing climate change. Give reasons for your
answers.
How can energy use be made more
sustainable?
Restrictions/Controls
Nuclear power – fission vs fusion
Carbon sequestration ( pg 294)
Renewable energy resources (pg 295)
Food production
Changing numbers in people suffering hunger
and starvation
Is GM the answer to supply problems?
Local/organic – can it provide enough?
How is local food production distorted by long
distance food transport to satisfy more affluent
countries?
Is organic agriculture more sustainable?
How can food production be made more
sustainable?
How do global consumption patterns affect local
producing areas?
Human populations - How does affluence effect resource
exploitation and environmental degradation?
Energy use and pollution
Water exploitation
Mineral exploitation
Human populations
How does uneven resource distribution affect
development?
How does the positive feedback of poverty
influence population growth (299-300) and
development?
SUMMARY - What can individuals, groups and the
authorities do at the local, national and international level?
Individuals
Local Authority
Groups
National Authority
International Authority
