1. Discussion point

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……
Alternatives? Cotton bags……last longer…….biodegradable saves using petroleum kinder to the environment….etc etc

5. Another Eco-Friendly material is JUTE

6. WVO WASTE VEGETABLE OIL AN 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 point What 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
