The Great Pacific Garbage Patch (GPGP) is a massive area of marine debris located in the North Pacific Ocean. The GPGP is estimated to be around 1.6 million square kilometers (about three times the size of France) and is made up of an estimated 1.8 trillion pieces of plastic waste, which is constantly being added to by the actions of humans. The GPGP is an alarming example of the impact of human pollution on our planet and has significant implications for the health of the ocean ecosystem and the creatures that inhabit it.
One of the biggest problems with the GPGP is the presence of microplastics, which are tiny particles of plastic that have been broken down by the action of sunlight and ocean waves. These microplastics are ingested by a wide range of marine life, including fish, turtles, and seabirds, leading to a range of negative impacts on their health and wellbeing. Microplastics can cause digestive problems, leading to malnutrition and starvation, and can also leach toxic chemicals into the animals' bodies, causing further harm.
Another significant impact of the GPGP on marine life is entanglement. Discarded fishing nets and other debris can ensnare marine creatures, leading to injury, infection, and even death. It is estimated that around 100,000 marine mammals and one million seabirds die each year due to entanglement in marine debris.
The GPGP also has wider implications for the health of the ocean ecosystem. The presence of large amounts of plastic waste can alter water chemistry, leading to changes in the nutrient balance and oxygen levels in the water. This can have knock-on effects on the entire food chain, from plankton to apex
predators, leading to declines in populations of certain species and changes in the structure of the ecosystem.
While the scale of the problem is daunting, there are steps being taken to address the issue of the GPGP. These include initiatives to reduce plastic waste and improve recycling rates, as well as programs to remove existing debris from the ocean. However, these efforts are hampered by the sheer scale of the problem and the lack of international cooperation on the issue.
