Plastic pollution is choking our oceans – literally. Around 8 million pieces of plastic find their way into the sea every single day.

The crazy thing? Most of it could be avoided with a few simple swaps and better habits. So, if you’ve ever felt hopeless about ocean plastic pollution, take a deep breath.

Below are 7 practical ocean plastic pollution solutions that are doable, effective, and, honestly, a lot easier than you might think.

1. Avoid the worst ocean plastic polluters

Some plastic items are repeat offenders in beach cleanups. The worst ocean polluters are:

• Cigarette butts – If you smoke, make sure they end up in a bin, not the beach.
• Plastic food wrappers – Try beeswax wraps or reusable snack bags.
• Plastic straws & stirrers – Most of us don’t need them. If you do, grab a reusable one.
• Plastic utensils – BYO fork and spoon (bamboo or metal).
• Plastic bottles & caps – Refillable bottles are your best friend.
• Plastic bags – Switch to sturdy reusable bags.
• Coffee cup lids – Bring your own cup.
• Disposable plates & cups – Stainless steel, ceramic, or glass are your forever options.

2. Cut back on toxic cleaning products

Plastic isn’t the only thing messing with our oceans. Your laundry detergent might be guilty, too.

Nasty ingredients to watch out for:

• Phosphates – Common additives in laundry and dishwashing detergents. They have low toxicity, cause nutrient pollution, and are harmful to algae. Plus, residues on dishes can cause skin irritation, nausea, or diarrhea. (1, 2)
• Surfactants – Used in detergents for cleansing, shampoos, creams, conditioners, etc. They can irritate and damage the skin, and high concentrations represent an environmental risk. 

Quick fixes:

• Take hazardous waste to collection locations – Never pour household products such as cleansers, beauty products, medicines, auto fluids, paint, and garden products down the drain. 
• Switch to toxic-free detergents – Look for cleaning & laundry products with natural ingredients, such as Meliora Laundry Powder.
• Switch to eco-friendly toothpaste – Get tooth tablets or toothpaste that is natural & plastic-free, or DIY this simple tooth powder.
• Use natural hair products – To avoid more toxic chemicals that can harm you & the ocean, start using eco-friendly shampoo alternatives. 
• Ditch commercial sunscreens – Chemicals found in sunscreen threaten the health of marine life and coral reefs. Check my article to find a list of natural and coral-safe sunscreens.

3. Ditch microbeads

Microbeads are tiny bits of plastic hiding in products like sunscreen, toothpaste, face scrubs, body wash, and even makeup.

If your scrub, toothpaste, or makeup contains “polyethylene” or “polypropylene” in the ingredients list – yep, that’s plastic.

They’re added for scrubbing or texture, and since they’re so tiny, they slip right through water treatment systems, ending up in rivers and oceans, where they release toxins and harm wildlife.

The fix? Switch to natural products that use safe, biodegradable exfoliants instead.

If your scrub, toothpaste, or makeup contains “polyethylene” or “polypropylene” in the ingredients list — yep, that’s plastic.

4. Avoid synthetic clothing

Synthetic clothes (polyester, nylon, acrylic) shed microplastics every time you wash them – making them the biggest source of microplastic pollution in the ocean. It accounts for 34.8% of global microplastic pollution in the ocean. (1) (2) They are ingested by marine animals, causing various physical injuries and negative impacts. (1) 

What you can do:

• Choose natural fabrics when buying new clothes.
• Use a laundry filter like Cora ball.
• Wash clothes less often.

5. Reduce, reuse, THEN recycle plastics

You can’t avoid plastic completely, but you can make it last longer before it becomes waste:

• Reuse & upcycle containers into storage, planters, or DIY projects.
• Recycle properly – check your local rules.
• Remember: Reduce first, recycle last.

6. Join (or start) a beach/river cleanup

By participating in such cleanups, you set an excellent example and prevent plastic pollution from entering the oceans. Here’s how to start:

1. Pick a location and scout it.
2. Bring gloves, buckets, and bags.
3. Coordinate with local waste services.
4. Get friends or volunteers to join.

Even joining one that’s already happening is a big help.

7. Support ocean organizations 

Not everyone can spend their weekends picking up trash, but you can support people who do:

• Donate
• Volunteer
• Buy their merch
• Share their work

Scary facts about ocean plastic pollution

• Humans may consume around 53,864 microplastic particles every year from seafood alone.
• Over 1 million mammals, fish, sharks, turtles, and birds are killed by ocean plastic each year.
• 4.8 to 12.7 million metric tons of plastic waste enter the ocean annually.
• The Great Pacific Garbage Patch, a swirling mass of microplastics, is twice the size of Texas (or three times France).
• Just 10 rivers carry over 90% of all ocean plastic waste.
• At this rate, there could be more plastic than fish in the ocean by 2050.
• 90% of seabirds have plastic in their stomachs.
• A single laundry load can release 700,000+ microplastic fibers.
• Two-thirds of the world’s fish stocks already contain plastic.
• The average person ingests 2,000 microplastic particles per week – about the weight of a credit card every month.

Final thoughts

Our oceans are in trouble. It may seem like it’s too late to act, but it’s not.

Plastic can be removed from oceans, and companies like The Ocean Cleanup are developing systems that collect floating plastic, aiming to remove 90% of ocean plastic over time.

Additionally, every piece of plastic we refuse, every cleanup we join, and every sustainable swap we make pushes us in the right direction.

With small, consistent changes in our daily lives, we can all work toward protecting the oceans instead of adding to the problem. The choice is ours.
