Reading that the arctic is a place that is battled with microplastic pollution makes me wonder how they got there at the first instance. When I visualize the arctic, I see it as a place with clear blue skies filled with ice and ocean waters but not a place where some of the worst microplastic pollution exists. So you might want to ask how these plastics get there.
The arctic is the least densely population region in the world so they cannot be consuming that much plastic but when we look at the total plastic that find their way to the ocean from land, and there are about 19 million metric tons of plastic that find their way to water bodies annually, but then while we can see the PET bottles and bags in water, we also find microplastics in water.
These plastics are anything smaller than 5mm in diameter but then you ask how we get this plastics in the water? Well, I will give you an example; when you wash your synthetic fabric clothes, there are tiny pieces of the fabric that break off to pollute the drain which then goes down the water. Even Big plastics can become microplastics over time but then you see fishermen are also responsible for a lot of microplastics in the oceans and this is because they dump gears into the oceans. This derelict gears like nets break down to become tiny microplastics.
Since microplastic is as a result of plastic breakdown, you will be surprised to know that this waste isn't found in places where there are a lot of people dwell ironically. This waste are found in polar regions making the arctic to have the highest number of microplastic. This wastes are not only in the water body, but also in the solid ice around there. The type of microplastic waste found in the arctic isn't one that is associated with water body alone but from distant sources brought to that region through ocean currents, and floating raft of Ice.
The origin of this plastics an be very difficult to identify but then it looks like all road of wastes lead to the arctic and it is not like living organisms are also not affected by microplastics, it has been found in seabirds, marine worms, fishes, and so on but then we need to look to stopping plastic waste from getting to our water. Addressing this issue requires a multifaceted approach such as proper plastic waste management would help, using biodegradable fishing net will also reduce the presence of these microplastics there, and recycling. Although this is not a final way to stop this waste from getting into our water bodies but with this, we can save a lot of animals, as well as our water body.
While these measures may not entirely eradicate the problem, they represent important strides toward safeguarding our water bodies and protecting vulnerable Arctic ecosystems from the harmful effects of microplastic pollution. By collectively addressing the root causes of plastic pollution, we can work towards preserving the integrity of our oceans and the diverse life they support.
