It is approximated that there is a stock of 86 million tons of plastic marine debris in the worldwide ocean as of the end of 2013, assuming that 1.4% of global plastics produced from 1950 to 2013 has entered the ocean and has accumulated there. [4]
It is estimated that there is a stock of 86 million tons of plastic marine debris in the worldwide ocean as of the end of 2013, with an assumption that 1.4% of global plastics produced from 1950 to 2013 has entered the ocean and has accumulated there. [9]
[1] [2] As of 2022, an estimated 51 trillion microplastics are floating in the surface water of the world's oceans. [3] A single 5mm piece of plastic can host 1,000s of different microbial species. [4] Some marine bacteria can break down plastic polymers and use the carbon as a source of energy. Microbes interacting with the surface of plastics.
Our oceans are full of plastic — an estimated 200 million metric tons. And it's the microscopic pieces that could be the biggest threat. Addressing the planet's ocean plastics problem
With the increasing use of plastic, human influence has become an issue as many types of (petrochemical) plastics do not biodegrade quickly, as would natural or organic materials. [1] The largest single type of plastic pollution (~10%) and majority of large plastic in the oceans is discarded and lost nets from the fishing industry. [2]
The alternative plastic world is a minefield, cloaked in sustainability marketing that at best is aspirational, and at worst causes as many problems as the products it is trying to replace.
In 2014, there were five areas across all the oceans where the majority of plastic concentrated. [8] Researchers collected a total of 3070 samples across the world to identify hot spots of surface level plastic pollution.
The U.S. and 174 other nations failed to agree on a new treaty to reduce the plastic pollution contaminating our environment, food, water, and even our bodies.
