English presentation about the GPGP. it includes the definition, causes, consequences, an example of an initiative to counteract and a quiz. used best for high school classes. not much information written down on the slides itself, but the sources are in the presentation to inquire more knowledge.

3. 01
What is it:
The
Great
Pacific
Garbage
Patch

4. Question
:
How big do you think
the GPGP is in Square
kilometres?

5. Answer:
1.6 MILLION square
kilometres

6. 357,
592

7. France fits into
the GPGP 3x!

8. What is the GPGP?
• Collection of marine debris
• Scientists conducted the most elaborate sampling method ever coordinated to
estimate the size:
• 30 boats, 652 surface nets, 2 flights
• Location is constantly changing due to winds and currents
• between north America and Japan

9. What is the GPGP?

10. 02
What causes it:
The
Great
Pacific
Garbage
Patch

11. What causes the GPGP?
North Equatorial current
California current
Kuroshio current
North Pacific subtropical current (20
million square kilometres)
North pacific current

12. What causes the GPGP?

13. What causes the GPGP?
• Currents and Gyres
• Amount of plastic accumulates because it isn’t biodegradable
• Made from microplastics
• ~70% of trash sinks to the bottom of the ocean
• 80% of Plastic from Land, 20% from marine sources
• Half the mass is made of fishing nets
• consumerism

14. 03
What are the
consequences:
The
Great
Pacific
Garbage
Patch

17. 84% of debris
samples are
found to
contain toxic
chemicals

18. 700 species
have
encountered
marine debris

19. 17% of those
species are on
the red list of
endangered
species (IUCN)

20. 180x more
plastic than
food at the
surface of the
ocean

22. 03
What is being
done to
counteract:
The
Great
Pacific
Garbage
Patch

23. Difficult to
clean up due
to:
• Microplastic
• Sheer size of the
patch; a cleanup with
our current
resources would take
around 67 ships per
year to clean up only
one percent of the
patch

24. An initiative: “The ocean cleanu
• Biggest independent no-profit clean-up
corporation to date
• Established over 10 years ago
• Already cleaned several millions of kilograms
from the ocean
• Goal: clean-up 90% of the plastic
• Strategy: intercepting plastic in rivers &
cleaning already accumulated plastic waste

26. What we can do:
•Donate to non-profit-organizations
such as “the ocean cleanup”
•Educate others
•Reduce plastic waste

27. 04
Quizz:
The
Great
Pacific
Garbage
Patch

28. Quiz!
• How many times the size of France is the GPGP?
 3x
• What makes up the vast majority of the waste in the GPGP?
 microplastics
• What is a Gyre?
 Large system of swirling ocean currents
• How does “ the ocean cleanup” counteract the GPGP?
Intercepting plastic in rivers to stop the inflow of pollution
and cleaning the already accumulated debris
