1 why we care about PLASTIC

2 in a landfill or in the ocean
1. How long does it take for a plastic bottle or a plastic bag to decompose? 450 years to 1000 years!!!! in a landfill or in the ocean

3 Richard Thompson, a marine biologist at the University of Plymouth
tied plastic produce bags to moorings in the ocean at and found that a year later you could still carry groceries in them.

4 2. How long does it take for plastic fishing line (monofilament) to decompose?
plastic fishing line will take 600 years to decompose ...plus it kills thousands of marine animals each day

5 3. When did manufacturing of plastic start?
1930s which means that plastic as we know it has only been around for ≈ 80 years

6 4. How much plastic ever made still exists today?
97% of all the plastic ever made still exists today! The other 3% was incinerated; otherwise it would still exist as well!

7 5. What is plastic made from?
Plastic is made from OIL

8 OIL is a non-renewable resource this means that one day oil will run out (probably in the next half century) Oil has taken millions of years to formed from dead plants and animals

9 ENVIRONMENTAL PROBLEMS
Oil has caused A LOT OF ENVIRONMENTAL PROBLEMS

10 ENVIRONMENTAL PROBLEMS
Oil has caused A LOT OF ENVIRONMENTAL PROBLEMS

11 6. Is it more difficult to recycle plastics than other materials?
TRUE Because there are several different types Each type needs to be recycled separately

12 7. How many different classifications of plastic are there?
The American Society of Plastics Industry developed a standard marking code to help consumers identify and sort the main types of plastic into 7 classifications There are about 50 different groups of plastics, with 100s of different varieties. All types of plastic are recyclable.

24 PS Polystyrene. Common Name: Styrofoam Products
PS Polystyrene Common Name: Styrofoam Products? egg cartons vending cups plastic cutlery foam meat or fish trays protective packaging for electronics

25

26 OTHER All other plastics Products
OTHER All other plastics Products? Plastic plates and cups Reusable drink bottles Gasoline containers 7

28 8. Is there a giant blob of garbage made mostly of tonnes (3 million tons) of plastic in the Pacific Ocean twice the size of Texas? YES

29

30 This place is called: The Great Pacific Garbage Patch or The Eastern Garbage Patch or The Pacific Trash Vortex

31 How big is it. How big is Texas
How big is it? How big is Texas? Texas = 696,241 km² (268,820 sq mi) How big is Texas x 2? Texas² = The Great Pacific Garbage Patch = 1,392,482 km² (537,640 sq mi)

32 Some references: country sq km sq miles Romania 238,391 km² 92,043 mi²
Greece 131,990 km² 50,949 mi² Bulgaria 110,910 km² 42,823 mi² Serbia 88,361 km² 34,116 mi² Croatia 56,542 km² 21,831 mi² Bosnia and Herzegovina 51,197 km² 19,767 mi² Albania 28,748 km² 11,100 mi² Macedonia 25,713 km² 9,779 mi² Montenegro 13,812 km² 5,019 mi² Kosovo 10,908 km² 4,212 mi² TOTAL AREA OF THE BALKANS 756,572 km² 291,639 mi² Texas 696,241 km² 268,820 mi² Texas² aka The Great Pacific Garbage Patch 1,392,482 km² 537,640 mi²

33 The Math: Approximately 55 Macedonias could fit in this area
Approximately 1.8 Balkans could fit in this area That is almost double Macedonia, Greece, Bulgaria, Albania, Serbia, Kosovo, Bosnia and Herzegovina, Croatia, Montenegro, Romania combined!!!

37 How did the Great Pacific Garbage Patch get there
How did the Great Pacific Garbage Patch get there? First Because there are many benefits of plastics

38 Benefits of Plastic Resistant to Chemicals
Plastics can be very resistant to chemicals. Consider all the corrosive cleaning fluids in your home. Most of them come in plastic containers.

39 Benefits of Plastic Electrical and Thermal Insulator
Plastic won't pass an electric current, which is why electric wiring, outlets, and appliances tend to be covered in plastic. Plastic also doesn't conduct heat very well, making it useful for keeping things warm, or cold.

40 Benefits of Plastic Excellent safety and hygiene properties
for food packaging Relatively inexpensive to produce we like to buy things that are cheap

41 Benefits of Plastic Light Weight
Lighter weight than competing materials reducing fuel consumption during transportation. Plastic is used in the frame structure of space stations and to make key components for automobiles.

42 Benefits of Plastic STRONG
Plastic is not only resistant to chemicals but also water and severe damage. plastic can be made strong, but light and doesn't rust or corrode. Plastic has extreme durability.

43 Benefits of Plastic Can Take Many Forms
Plastics can be made into all kinds of shapes From thin fibers to bottles or dashboards for cars Some plastics can be stretched into sheets Other plastics can be puffed up to make cups

44 Benefits of Plastic Can Perform Many Jobs
Extreme versatility and ability to be tailored to meet very specific technical needs. By altering a plastic's chemical recipe you can make it perform a specific job, from keeping food fresh to stopping bullets. This is what really sets plastic apart from other materials.

45 How did the Great Pacific Garbage Patch get there
How did the Great Pacific Garbage Patch get there? Second Because we dump a lot of plastic into the ocean 

46 “It was not unlike an Arctic vessel pushing through chunks of brash ice, except what was bobbing around them was a fright of cups, bottle caps, tangles of fish netting and monofilament line, bits of polystyrene packaging, six-pack rings, spent balloons, filmy scraps of sandwich wrap, and limp plastic bags that defied counting.” - Captain Moore

47

48 Way back in 1975, the U.S. National Academy of Sciences had estimated that all oceangoing vessels together dumped 3.63 million kg (8 million lbs) of plastic annually.

49

50 Today, more recent research showed the world’s merchant fleet alone shamelessly tossing around 639,000 plastic containers EVERY DAY!!!

51 An estimated billion kg (14 billion lbs) of trash, much of it plastic is dumped in the world’s oceans every year.

52

53 In the Great Pacific Garbage Patch the ocean surface alone has 2
In the Great Pacific Garbage Patch the ocean surface alone has million tonnes (3 million tons) of plastic

54 6 X more plastic by weight than plankton on the ocean’s surface
= 6 X more plastic by weight than plankton on the ocean’s surface

55 An estimated 100,000 marine animals perished last year as a result of litter in our oceans.

56 Off the coast of Africa people harvest plastic bags and weave them into hats and shawls They collect an average of 30,000 bags a month.

57 WHAT CAN YOU DO?

58 WHAT YOU CAN DO ALWAYS RECYCLE PLASTIC
Otherwise it will sit in a landfill for the next 450 to 1000 years

59 WHAT YOU CAN DO When you recycle plastic bottles
ALWAYS REMOVE THE BOTTLE TOPS because then they are more easily crushed then they can occupy less space
