1. Sustainability

2. Objectives What is sustainability? Why is a sustainable lifestyle important for the health of the planet? Sustainability involves: Recycling Energy efficient houses Ecological transport

3. Sustainable Development Sustainable development is a pattern of resource use that aims to meet human needs while preserving the environment so that these needs can be met not only in the present, but in the indefinite future

4. Recycling http://www.bexley.gov.uk/service/environ/recycling/recyclingvideo.html http://www.bexley.gov.uk/service/environ/recycling/recyclingvideo.html We need to see waste as a resource Rather than a problem Most towns and cities now have the facilities to recycle glass, paper, aluminium (cans) and rags (old clothes) It is possible to recycle other things to

5. Transport and the environment The impact of global warming is becoming evermore accepted as a critical risk and a continued rise in CO 2 concentrations means that a catastrophic change in the earth’s temperature may happen. In the UK transport is responsible for 25% of CO 2 emissions, with road transport accounting for around three quarters of this 25%. This means that transport can offer a substantial reduction in overall CO 2 emissions

7. Biofuel http://www.sciencefriday.com/videos/watch/10079 http://www.sciencefriday.com/videos/watch/10079 Biofuel is defined as solid, liquid or gaseous fuel derived from relatively recently dead biological material and is distinguished from fossil fuels, which are derived from long dead biological material Theoretically, biofuels can be produced from any (biological) carbon source; although, the most common sources are photosynthetic plants

8. Alternative Transport A hybrid vehicle is a vehicle that uses two or more distinct power sources to move the vehicle Power sources include: On-board or out-board rechargeable energy storage Gasoline or Diesel Fuel Hydrogen Compressed air Human powered e.g. pedaling or rowing Wind Compressed or liquefied natural gas Solar energy

9. Energy Efficient house Keeping your home warm is expensive, especially in winter Using insulation helps to keep the heat in Double glazing, draught- proofing around the door and curtains in the windows can also help Using energy efficient light bulbs helps reduce the cost of electricity Solar panels can be used to turn sunlight into electrical energy offering a further reduction in the cost of consumable energy
