The Plastic Island's Weight: A Troubling Environmental Concern

The Great Pacific Garbage Patch is a large collection of plastic waste in the Pacific Ocean. It is estimated to weigh 87,000 to 100,000 tons, which is equivalent to more than 740 Boeing 777s or 43,000 cars. The patch covers 1.6 million square kilometres and contains more than 1.8 trillion pieces of plastic.

The Great Pacific Garbage Patch weighs 87,000 tons

The mass of the plastic in the Great Pacific Garbage Patch (GPGP) was estimated to be approximately 100,000 tons, which is 4-16 times more than previous calculations. This is equivalent to more than 740 Boeing 777s.

The large and medium-sized plastics bigger than 2 inches, known as megaplastics and macroplastics, comprised more than 75% of the total mass of the GPGP. Microplastics made up 94% of the total number of pieces of plastic in the patch, but only accounted for 8% of the mass.

The GPGP was discovered in 1997 by Charles Moore, who continues to raise awareness through his environmental organisation, the Algalita Marine Research Foundation. During a 2014 expedition, Moore and his team used aerial drones to assess the extent of the trash below. They determined that there is 100 times more plastic by weight than previously measured.

This is 16 times more than previous estimates

The Great Pacific Garbage Patch weighs an estimated 87,000 tons, or 100,000 tons according to another source. This is 16 times more than previous estimates. To put this into perspective, this is the equivalent of more than 43,000 cars or over 740 Boeing 777s.

The Great Pacific Garbage Patch (GPGP) is a collection of plastic waste in the Pacific Ocean. It was discovered in 1997 by Charles Moore, who has since been raising awareness of the issue through his environmental organisation, the Algalita Marine Research Foundation.

Previous estimates of the weight of the GPGP were based on sampling methods that involved scientists hopping on a boat and trawling the trash with fine nets. However, these methods may not have been accurate as they did not account for the large and medium-sized plastics that make up more than 75% of the total mass of the patch.

In 2014, Moore and his team used aerial drones to assess the extent of the trash from above. This method revealed that there is 100 times more plastic by weight than previously measured. The team also discovered more permanent plastic features, or islands, some over 15 meters (50 feet) in length.

It covers 1.6 million square kilometres

The Great Pacific Garbage Patch (GPGP) is a huge collection of plastic waste in the Pacific Ocean. It is estimated to weigh 87,000 to 100,000 tons and covers 1.6 million square kilometres, or 617,000 square miles. This is a massive area, equivalent to the size of several small countries. To put it into perspective, the GPGP is larger than the state of Texas or the country of France.

The GPGP is made up of more than 1.8 trillion pieces of plastic, ranging from large and medium-sized pieces (known as megaplastics and macroplastics) to tiny microplastics. These microplastics make up 94% of the total number of pieces of plastic in the patch but only account for 8% of the mass. The larger plastics, on the other hand, comprise more than 75% of the total mass.

The patch is not a solid mass of plastic but rather a collection of plastic debris floating in the ocean. It is described as having a "soup-like" consistency, with varying densities throughout. The centre of the GPGP has the highest density, while the further boundaries are less dense. This means that the plastic is not evenly distributed throughout the 1.6 million square kilometres but is more concentrated in certain areas.

The size of the GPGP is alarming, and it continues to grow. Charles Moore, who discovered the patch in 1997, has been raising awareness about the issue through his environmental organisation, the Algalita Marine Research Foundation. During a 2014 expedition, Moore and his team used aerial drones to assess the extent of the trash below. Their findings revealed that there is 100 times more plastic by weight than previously measured.

94% of the plastic in the patch is microplastic

The Great Pacific Garbage Patch (GPGP) weighs an estimated 100,000 tonnes, which is 4-16 times more than previous calculations. This is equivalent to more than 740 Boeing 777s or 43,000 cars. The GPGP is made up of more than 1.8 trillion pieces of plastic, 94% of which are microplastics. While microplastics make up the majority of the pieces of plastic in the patch, they only account for 8% of the mass. This is because the large and medium-sized plastics bigger than 2 inches, known as megaplastics and macroplastics, comprise more than 75% of the total mass of the GPGP.

The plastic was found to originate in Asia

The Great Pacific Garbage Patch weighs an estimated 100,000 tonnes, which is equivalent to more than 740 Boeing 777s or 43,000 cars. It is made up of more than 1.8 trillion pieces of plastic, 94% of which are microplastics. However, these microplastics only account for 8% of the total mass. The remaining 75% of the mass is made up of megaplastics and macroplastics, which are larger pieces of plastic bigger than 2 inches. Based on inscriptions, most of the plastic collected in the study originated in Asia, specifically China and Japan. This is likely due to the North Pacific Current, which runs west to east.
