Plastic Is Killing Our Oceans – Here’s What You Need to Know

Approximately 40% of the world’s 7.6 billion people live within 62 miles of an ocean coast. For the other 60%, some of whom may never have even seen an ocean, the seas still play a vital role in their lives.

Oil and consumer goods are moved around the world on vast ships, keeping the wheels of commerce, and vehicles, turning. Most importantly, the ocean is vital to the food chain.

Unfortunately, we collectively treat the oceans worse than most of us treat the inside of our cars. Every year, anywhere from about 8 to 12 million US tons of plastic end up in the world’s oceans.

For perspective, that’s close to three times as heavy as all the elephants on Earth combined.

The scale of the problem is enormous, but it’s not a lost cause. Just like when your dentist says you can avoid further problems with your gums if you brush better and floss often, a change in how we live could be the catalyst for cleaner oceans in the future.

Read on to learn about the true scope of the issue, and why plastics in our oceans are such a problem.

We’ll finish by looking at some of the methods currently in use for ocean cleanup, what the future may hold, and what you and I can do to help put the brakes on plastic pollution.

Coming to Terms with the Problem

Plastics ushered in an era of incredible convenience and are largely responsible for our modern era of mass consumerism.

Things made with plastic are inexpensive to produce, and they’re lighter (and hence more cost-effective) to ship. They’re also incredibly versatile. Look around you and think about how much plastic there is within sight of you right now.

Two of plastic’s other appealing qualities, durability and comparatively low purchase cost, are also its greatest downfalls.

Because plastic products are often inexpensive, we tend to throw them away without thinking, either because the item was a single- or low-use product, or because it was cheap to replace. They also last a long time. Plastic breaks down very slowly.

All this means there is a lot of plastic in the world. And far too much of it ends up escaping the proper waste disposal streams. Unfortunately, once it leaves the waste stream, it tends to stay out of it.

You don’t have to live anywhere near water to know that plastic has a way of finding its way out of the confines of our garbage cans and recycling boxes. When was the last time any of you urban-dwellers went for a walk and didn’t see a plastic water bottle or grocery bag at the side of the road, or pressed up against a fence?

But, let’s skip over that issue for now and focus on the world’s oceans. To say there’s a lot of garbage in the oceans is an understatement!

Here are some fast facts to put it in perspective:

*Every minute, an amount of plastic equal to a full garbage truckload is deposited in our oceans

*Of the plastic that ends up in the oceans each year, 236,000 tons are microplastics, minuscule particles of plastic smaller than the nail of your pinky finger

*The amount of plastic in the ocean is set to increase tenfold by 2020
It is projected that by 2050 the weight of all the plastic in the oceans will exceed the weight of all the fish

*This is not just a surface problem – plastic has been found 7miles (11km) deep, in some of the most remote and least understood ecosystems on Earth

Plastic in the ocean we must stop

Where Does All the Plastic in the Ocean Come From?

Scientists’ best estimates are that 80% of the debris in the ocean comes from land-based activities. The remainder comes from oil rigs, private boats, commercial ships losing cargo, and fishing vessels dropping nets and other gear.

The debris itself is comprised of everything plastic you can conceive of: automobile parts, toys, cigarette lighters, beverage bottles, and countless tiny pieces beyond identification.

While just about every country on the planet contributes to the problem, certain countries lead the way.

Here’s a graphic of the top 10 annual global plastic polluters, also showing where the USA stands in relation, contributing 336,000 metric tons of plastic waste to the oceans every year:

How Plastic Garbage Ends up in the Ocean

Most of the world’s major producers and consumers of plastic do not have waste management facilities in place to handle it all. They lack adequate collection, recycling, and disposal systems.

Some of the garbage is deliberately and illegally dumped straight into the ocean. Even where garbage dumps exist, poor containment can lead to wind-blown plastics ending up in rivers, lakes, and ultimately oceans.

In the Philippines, one city has dumped its garbage on a beach for the past 50 years.

On an individual level, garbage left or lost at the beach or dropped in rivers contributes to the problem. Even plastics flushed down the toilet can sometimes find their way to the ocean.

Once it’s in the ocean, however, where does it all end up?
