The Great Pacific Garbage Patch (GPGP) is the largest accumulation zone of ocean plastic waste in the world.

It is located halfway between California and Hawaii. And it is getting worse, fast.

Scientists have been mapping plastic in the area since then the 1970s. However, the phenomenon started to grow, possibly in the 1950s.

The vast majority of the plastic mass found in the GPGP are large objects.

However, if not collected, and because of UV lights, they are destined to break down into dangerous microplastics over the next few decades.

Unless we clean it up. Fortunately, around 2011, a simple yet ingenious idea was born in Europe.

The Ocean Cleanup was founded by Boyan Slat, a Dutch inventor who, at the age of 16, decided he wanted to develop a technology that could address the problem of plastic pollution in the world's oceans.

He and his team envisioned a network of long floating screens that would concentrate the plastic so that we could then extract, store it, and ship it to land.

The dream has become a reality, and the Ocean Cleanup deployed its first floating barriers in 2018. The GPGP may have its days numbered.

But what exactly is the Great Pacific Garbage Patch? Here's everything you need to know about the GPGP:

1. The Great Pacific Garbage Patch measures 1.6 million square kilometers and is located in the North Pacific Ocean;

2. 99 percent of all marine debris found in the GPGP is plastic;

3. The GPGP contains over 1.8 trillion pieces of plastic, which equals 250 pieces for every human on the planet;

4. The total mass weighs 8,000 tons, the equivalent of 500 Jumbo Jets, and four to six times more than previous estimates;

5. 92 percent of the mass is composed of large plastic items;

6. From an absolute count perspective, only 6 percent of all plastic objects are larger than 5 millimeters;

7. The Great Pacific Garbage Patch is three times the size of France or two times the size of Texas;

8. In 2015, the Ocean Cleanup project crossed the patch with 30 boats and collected 1.2 million plastic samples;

9. The Mega Expedition also retrieved a large number of ghost nets, one of the biggest threats to marine life;

10. The first aerial reconnaissance mission of the GPGP took place in October 2016. The Ocean Cleanup team was able to get a 3D analysis of the debris;

11. 50 percent of the Great Pacific Garbage Patch's floating trash consists of ghost nets and discarded fishing gear;

12. The total mass of plastic found in the GPGP is four to 16 times higher than previous studies have shown;

13. Among thousands of unlikely objects floating in the Great Pacific Garbage Patch, the Ocean Cleanup researchers retrieved a 1977 plastic crate;

14. The waters of the GPGP hold 180 times more plastic than marine life by weight;

15. The concentration levels in the center of the Great Pacific Garbage Patch feature the highest density, reaching hundreds of kg/km2 and decreasing down to 10 kg/km2 in the outermost region;

16. The vast majority of plastics found in the GPGP are made of rigid or hard polyethylene (PE), polypropylene (PP), and fishing gear;

17. 84 percent of the plastics in the Great Pacific Garbage Patch contain at least one type of Persistent Bioaccumulative Toxic (PBT) chemical;

18. Most buoyant microplastics in the GPGP are present on or near the surface of the water, between zero and five meters of depth;

19. The Ocean Cleanup technology hopes to remove half of the Great Pacific Garbage Patch in five years using 50 one-to-two-kilometer High-Density Polyethylene (HDPE) floating systems;

20. Each system will use the natural ocean currents to collect up to three tons of debris per week;

21. All plastic retrieved from the GPGP is recycled and used to produce B2C products;

22. The first ocean prototype was successfully tested in 2016 on the North Sea;

23. Despite the rumors, the giant plastic island cannot be seen from space because most of it is microplastics with open water in between;
