Causes of plastic pollution in oceans and seas

The Sources Behind Plastics Polluting Our Seas and Oceans

Plastic pollution is a growing environmental issue that affects our oceans and seas. Plastic waste is present in every part of the marine environment, from the polar ice caps to the deepest coral reefs. It has been estimated that more than 8 million tons of plastic enter our oceans each year, threatening marine ecosystems with devastating consequences. The sources of plastic pollution range from single-use plastics to industrial and shipping containers, as well as fishing gear and other debris left behind by human activities at sea or on land. Every part of the world contributes to this problem through human carelessness, but it is important to understand what causes this problem so we can work towards solutions for reducing plastic pollution in our ocean ecosystems.

Types of Plastics Found in the Ocean

Single-use plastics are one of the most common types of plastic found in our oceans. This includes items such as plastic bags, straws, utensils, and beverage containers which are used once or a few times before they are discarded. These single-use plastics can end up in the ocean through improper disposal or littering on land. In addition to this direct source of pollution, many single-use plastics also enter our oceans by way of storm drains and wastewater treatment plants that do not have adequate filtration systems in place to remove them.

Fishing gear is another major contributor to marine plastic pollution. Lost fishing nets account for around 10% of all marine debris worldwide and can remain active even after abandonment, trapping fish and other marine life while continuing to accumulate more debris over time. Many pieces of fishing gear also contain smaller fragments called “microplastics” which are further broken down into microbeads that make their way into our food chain when consumed by aquatic organisms like plankton or small fish species commonly eaten by humans.

Shipping containers provide yet another source for oceanic plastic pollution due to their sheer size and weight when full with cargo materials made from various forms of plastic packaging material including foam insulation blocks and bubble wrap among others – these materials often end up spilling out at sea during transport if not properly secured beforehand leading to significant amounts being deposited in the water column from those ships alone.

Industrial Plastics come from a variety sources including manufacturing facilities located near bodies of water where runoff containing these pollutants enters directly into rivers lakes estuaries bays etc As industrial activity increases so does the amount entering our waterways making it an important factor contributing towards global levels overall

Impacts of Plastic Pollution on Marine Life

The impacts of plastic pollution on marine life are far-reaching and incredibly damaging. One of the most common ways that plastic waste affects wildlife is through entanglement. Many sea animals, such as dolphins and seals, can get entangled in discarded fishing nets or other debris that has been left behind in the ocean. This can lead to serious injury or even death due to starvation from being unable to move freely, suffocation from lack of oxygen or becoming prey for predators.

Ingestion and digestive problems are another major consequence of plastic pollution for marine life. Animals like turtles often mistake floating pieces of plastic for food resulting in a range of issues including blockages in their intestines which prevent them from digesting real food properly leading to malnutrition, dehydration and eventually death if untreated quickly enough. In addition to this, many plastics contain toxic chemicals which leach into waterways when they break down resulting in further health complications when ingested by aquatic organisms directly or indirectly via consumption higher up the food chain by larger species commonly eaten by humans like tuna and salmon amongst others.

Finally, infection caused by plastic pollution poses an additional threat to our oceans’ fragile ecosystems with both biofouling (the accumulation of microorganisms) as well as chemical pollutants accumulating on surfaces creating ideal conditions for disease-causing bacteria such as salmonella to thrive – a single piece containing millions upon millions more than nature alone could ever provide leading potentially devastating consequences depending on where it ends up settling within any given habitat at any given time

Eliminating the Use of Plastics

Reducing the use of single-use plastics is an important step to eliminating it from our oceans and environment. One way to reduce their use is through public education campaigns that encourage consumers to choose reusable products over single-use items whenever possible. Legislation can also play a role in reducing plastic consumption, as bans on certain types of single-use plastics have been successful in many places around the world. Additionally, governments can provide incentives for companies to switch away from using plastic packaging or containers when possible and instead opt for more sustainable materials like paper or bioplastics derived from renewable sources such as cornstarch or sugar cane derivatives.

In addition to reducing the production and use of single-use plastics, it is important to consider alternatives that are available as replacements wherever we still need them – this includes items like reusable water bottles made from stainless steel or glass which offer both durability and convenience while avoiding disposal issues associated with traditional disposable bottles; compostable cutlery made from materials such as bamboo; shopping bags designed specifically for carrying groceries which can be reused multiple times before being recycled; and even biodegradable straws crafted out of plant-based materials like wheatgrass stalks. By substituting these kinds of options into everyday life, we can help minimize our reliance on harmful plastic products while making sure essential needs are met without sacrificing convenience or comfort levels entirely along the way.

Friends of the Sea’s Work to Address Plastic Pollution

Friends of the Sea is an organization dedicated to protecting our oceans and marine life from plastic pollution. To this end, they have undertaken a number of projects designed to reduce plastic pollution in various ways. One example is their “Clean Up The Coast” campaign, which has seen volunteers around the world join forces to collect discarded plastics from beaches and waterways before they can reach our ocean ecosystems. This work is supplemented by public education initiatives that raise awareness about where plastic waste comes from and how it affects marine life, as well as research projects aimed at better understanding the impacts of marine plastic on both wildlife and human health alike.

In addition to these efforts, Friends of the Sea also engages in policy advocacy campaigns encouraging governments worldwide to pass laws limiting single-use plastics or banning them altogether when possible – something which has already been achieved in some places such as California with their recently passed statewide ban on disposable carryout bags being distributed at retail stores across the state helping contribute towards reducing overall levels even further still! Finally, they provide resources for individuals wanting get involved with local clean up events or educational activities related to ocean conservation topics like this one allowing everyone everywhere access regardless if its near home or not making it easier than ever before for people all over make positive changes within their own communities too directly impacting global levels overall thanks largely due much in part due continued support provided via Friends Of The Seas’s ongoing efforts year after year!


In conclusion, plastic pollution in the ocean is a major environmental issue that must be addressed. Reducing our reliance on single-use plastics and increasing public education about the devastating impacts of plastic waste are two essential steps toward achieving solutions. Governments around the world should continue to pass legislation limiting or banning single-use items whenever possible while providing incentives for companies to switch away from using plastic packaging materials when available alternatives exist. Additionally, organizations like Friends of the Sea can help facilitate positive change through their ongoing campaigns aimed at curbing marine debris and raising awareness about these issues among both local communities and larger populations alike. With continued efforts from all involved, we can reduce current levels of oceanic plastic pollution and ultimately create a cleaner, safer future for generations to come
