8 Ways You Are Harming The Ocean And Don't Even Know It

Posted: Updated:

Every single living thing on Earth is connected to the ocean. Even you, World's Driest Place, The Atacama Desert! And every year for World Oceans Day, on June 8, we get to profess our love for the 332.5 million cubic miles of our planet that’s made of water. Unfortunately, we’re all guilty of hurting the ocean, if just a little bit, in ways that might be surprising. Here are eight of them, followed by tips to help us right our wrongful ways.

1. Driving

Each time you drive, your car's carbon emissions spread into the atmosphere and the oceans absorb a quarter of the world's carbon dioxide emissions annually. Here's another way of putting it: As atmospheric carbon dioxide rises, so it does in the ocean. This is bad, because lower pH levels make it hard for shelled organisms, such as clams, oysters, corals and some plankton, to live. When these backbones of the ocean die, the repercussions carry throughout the whole ecosystem (if coral reefs are unable to recover from, say, pounding storms, it would affect the million-or-so species that depend on them). Add that to present estimates of future carbon dioxide levels indicating the ocean could be nearly 150 percent more acidic by the 2100s.

What you should do about it: Change your commute by biking or carpooling -- or take inspiration from some of the most adventurous commuters ever.

2. Buying seafood obliviously

Turns out there aren't as many fish in the sea as the broken-hearted might hope. Overfishing, largely due to unsustainable practices by commercial fishing, combined with the collapse of reef systems, could lead to the demise of all the world's fisheries by 2048. And buying fish from places without regard for their sources lends to this trend -- especially if you eat shrimp (most of which is trawl-caught, meaning that up to 15 pounds of unintended wildlife are caught for every one pound of shrimp).

What you should do about it: Use the National Geographic seafood selector, or these pocket guides from Seafood Watch that tell you which fish are more sustainable to eat, and purchase the safe fish from your farmers market. Ask your local store’s fishmonger about its fishing practices. You can also use the Marine Stewardship Council's database of sustainable places to dine or buy your fish.

3. Growing flowers

Even something as delightful as your rose garden can be bad for the ocean. According to the U.S. Centers for Disease Control, 75 million pounds of synthetic chemicals such as fertilizers and pesticides are put on our crops and gardens every year. The extra nutrients run off into creeks, streams, rivers, lakes, and the ocean. Algae dies and decomposes, sucking the oxygen out of the water and creating "dead zones." Fish also ingest the chemicals, which make them sick. We eat those fish, and we get sick. It's nature's irony.

What you should do about it: Keep your garden as organic as possible.

4. Ordering take-out

Although more and more cities restrict the commercial use of styrofoam containers and plastic bags at restaurants and grocery stores, plastic is still a huge threat to marine life. Plastic bags can take one to two decades to decompose in the ocean, and plastic bottles? A century. Polystyrene, on the other hand (the plastic most commonly used in utensils and Styrofoam), breaks up much faster, but releases the toxic bisphenol A into the waters, endangering sea and land life (basically, all life).

What you should do about it: Instead of buying bottled water, carry a stainless-steel reusable bottle. Use canvas tote bags when you shop, and frequent restaurants that use biodegradable or recycled containers, or have them package your food in your own containers.

5. Snorkeling

OK, observing the ocean isn't inherently bad for it, but if you stand on a reef to get a better look at that parrot fish, for example, you damage the reef. And because the ocean's acidification level is rising at unprecedented rates, it will be that much harder for the reef to bounce back. So you know that old hikers' saying of "leaving only footprints"? Not when snorkeling.

What you should do about it: This one's easy -- look, but don't touch.

6. Using sunscreen

There's no such thing as waterproof sunscreen. And using sunscreen incorrectly -- slathering it on and immediately jumping into the ocean -- will wash it off and send it into the waters. Scientists have recently found that a common chemical used in cosmetics and sunscreens, benzophenone-2 (which blocks ultraviolet rays), can cause corals to bleach, change their DNA, and kill young coral.

What you should do about it: Use these tips on sunscreen application. A golf ball-sized amount is a good measure, every 2 hours, and after you sweat a lot or swim. In addition to sunscreen, wear a hat at the beach, sit under an umbrella, and recycle those plastic sunscreen bottles when you're done.

7. Beach combing

When you take a shell away from the beach, you have a nice keepsake to glue to a picture frame or put on a necklace. But when millions of tourists do it with you, the ecosystem suffers. Beaches can erode and biodiversity drops when the crabs, small fish, and algae that depend on the shells leave or die.

What you should do about it: Leave them alone. Also, join a local beach cleanup to pick out the cigarette butts, food wrappers, and other trash from the shells so that animals pick the right thing to live on.

8. Stopping at this article

We're grateful you've made it to the bottom of the article, but merely reading something on the Internet isn’t enough to help the oceans.

What you should do about it: Be a slacktivist no more: Get involved with your community or jump into any of these national organizations or "voluntour" for your next vacation. Even buying merchandise from their stores supports them, so check out PangeaSeed for good art, or send an environmental nonprofit some money. Whatever you do, just remember that making even small decisions every day can add up to a big impact.
