  2. Animals eat them and die

  3. Discussion • How do plastic bags harm the environment? • Landscape • Animals • Pollution • What can we do to stop the damage caused by plastic bags?

  4. Alternatives?Cotton bags……last longer…….biodegradablesaves using petroleumkinder to the environment….etc etc

  5. Another Eco-Friendly material is JUTE

  6. WVOWASTE VEGETABLE OILAN ALTERNATIVE TO PETROLEUM • WVO = Oil that restaurants have used to cook food, like French fries, and this is then thrown away. • It is already available! • Over 11 billions produced in 2000 • Restaurants are happy to give it away because they usually have to pay to dispose ot it • IT IS CHEAP AND EASY TO USE!

  7. WVO STEPS • 1. Fast-food restaurant produces WVO • 2. WVO is collected • It is changed into fuel • People use fuel to power cars, trucks etc. • Look at picture on page 89 of Academic Connections book.

  8. WVO IS A SIMPLE AND GREEN ALTERNATIVE TO PETROLUEM • It is easy to use. • The oil is cleaned • You have to buy a new part for your car • You can get it from restaurants for FREE • It does not pollute the environment!

  9. Discussion Point • What HARM DOES PLASTIC BAGS DO TO ANIMALS BOTH ON LAND AND IN THE SEA? • HOW DO THEY SPOIL OUR LANDSCAPES? • WHAT CAN WE DO TO STOP THE USE OF PLASTIC BAGS? • SHOULD SHOPS BE BANNED FROM USING THEM

  10. Discussion pointWhat are bio-fuels? • What are they made from • Name four • What is WVO? Name three reasons why it is a good alternative to using petrol in our cars • Why are bio-fuels a good alternative to fossil fuels, like crude oil (petroleum)

  11. Bio-fuels are made from vegetables such as….

  12. Also…..Soya beans

  13. Sugarcane! Renewable, safe, biodegradable Alternatives to petroleum

  14. BIO -FUELS • ARE BIO DEGRADABLE • THEY DO NOT POLLUTE THE ENVIRONMENT • IF THEY GET ONLAND OR WATER THEY ARE EASIER AND LESS EXPENSIVE TO CLEAN UP • WHEN PRODUCED AND BURNED THEY CAUSE LESS POLLUTION THAN PETROEUM • OTHER SOURCES OF NATURAL ENERGY INCLUDE WIND, AIR, AND SUN (SOLAR) ENERGY. • ALL ARE ALTERNATIVES TO FOSSIL FUELS • THEY ARE ALL RENEWABLE (THAT IS THEY ARE ABLE TO BE REPRODUCED NATURALLY IN A SHORT SPACE OF TIME0

  15. Reasons for making bio-fuels PROBLEMS • Petroleum is toxic • People want clean and safe products • People worry about dangerous chemicals • Fossil fuels pollute the air when burned • Chemical products are dangerous for our health • People depend too much on petroleum which is harmful and NONRENEWABLE

  16. SOLUTIONS • Use safe and renewable sources of energy such as? (make a list) • Bio-fuels are clean and safe

  17. Problems with bio-fuels • Rainforests are destroyed in order to grow more vegetables for bio-fuels • Farmers grow less vegetables for food and vegetables therefore become more expensive • We need a lot more land to grow vegetables on………..which we do not always have
