But although most people know that plastic cannot be absorbed back into the environment, there are many that are unaware just how much plastic ends up in our oceans - and how detrimental this can be.
In addition to being bad for the environment, the amount of plastic in the ocean continues to grow - affecting wildlife and humans alike.
Although it is difficult to identify exactly how much plastic is in the ocean due to micro-particles and the amount that has sunk to the bottom, most scientists estimate that eight million metric tons of plastic end up in our oceans each year - adding to the estimated 150 million metric tons currently circulating our oceans.
To put that number into perspective, the amount is equivalent to a garbage truck full of plastic dumping plastic into the ocean every minute.
And that figure is only expected to increase as plastic production and consumption continue.
According to the Ocean Conservancy, in less than 10 years, scientists predict there will be 250 million metric tonnes in the ocean and by 2050, there will be more plastic in the oceans than there are fish.
The world now produces nearly 300 million tons of plastic each year - a significant amount of which will end up in the oceans.
Unfortunately, although plastic is a useful product, many of these products are created for single-use, with an estimated 50 per cent of plastic used once and thrown away.
Not only is this harmful to the environment and the oceans, but it is also harmful to wildlife - where it impacts nearly 700 species in the ocean, and humans.
According to the Ocean Conservancy, plastic has been found in more than 60 per cent of all seabirds and 100 per cent of sea turtle species.
Ingesting plastic has life-threatening effects on wildlife - and this plastic eventually ends up being digested by humans.
Brits who consume fish are at risk of consuming 11,000 fragments of plastic each year, according to a recent Belgian study. And half of all plastic manufactured becomes trash in less than a year.
Currently, only nine per cent of the world’s plastic is recycled - a problem because most plastics are not biodegradable and typically take more than 400 years to degrade.
And it never fully degrades, rather it breaks down into smaller and smaller pieces that are eventually ingested by marine life.
Single-use plastics are the worst offenders and include plastic bags, food packaging, and straws.
Most of the plastic produced is used in packaging - which accounts for more than 40 per cent of non-fibre plastic, according to a study published in the journal Science Advances.
However, nearly all solid plastic, such as water bottles, are capable of being recycled.
While a complete solution to the plastic problem is likely years away, small changes can make a big difference.
Choosing to forgo straws, as many restaurants have begun to do, lessens the plastic waste and protects wildlife.
Switching to reusable bags when shopping can also make a difference - as single-use plastic bags are a large part of the problem.
And knowing the proper way to recycle common plastics is necessary if humans want to keep plastics from the ocean.
Another potential solution, found recently by accident, relies on a mutant enzyme that is capable of breaking down plastic bottles.
Published in the journal Proceedings of the National Academy of Sciences, scientists accidentally discovered the enzyme - which could recycle plastic for reuse as plastic and fundamentally reduce the amount of plastic in the environment, according to the author of the study, University of Portsmouth professor John McGeehan.
If each person dedicated their attention to the plastic issue, the detrimental effects of plastic on the world could be lessened, McGeehan says.
