Trashy Beaches are Everywhere: Photos

Intro Recently, Typhoon Vincent knocked cartons into the sea off the coast of Hong Kong. The cartons were filled with bags of small plastic pellets that are now spread far and wide across Hong Kong's beaches. The pellets themselves are non-toxic, but they are prone to absorbing toxins from the surrounding environment. If they are eaten by fish after they've absorbed toxins, the fish's flesh will become toxic as well. Once this happens it's a short jump to us consuming the now-toxic fish. Complex interactions like this are common in nature, but often overlooked by the media. Fish eating our discarded or spilled trash largely goes unnoticed, but it can have dire effects on many populations of humans and animals. We need to pay attention to all the ways and places where this trash leaves our hands and enters the ecosystem.

Gatahan, Malaysia The beaches of Gatahan in Malaysia would be a far more beautiful sight without the plastics. One good storm and these will wash out and join their bretheren in the Pacific Garbage Patch. Bottles like these were made from the plastic pellets currently sitting on the beaches of Hong Kong.

London Olympics Now, at the 2012 London Olympic Games, the beaches of England are crowded with spectators. Their trash, if not properly disposed of, could easily end up in the English Channel or be washed out to sea.

English Beaches Outside of the Olympics, other English beaches are experiencing events. Here, the Relentless Boardmasters pro-surfing competition is only part of a five-day surf-skate and music festival. Any rubbish left behind could easily spread to the surrounding waterways.

California It's not as easy as "don't be a litterbug." Here in California, a popular surfing destination, trash has piled up on a beach due to storms and swollen seas. The ocean swells will pull any trash left on the beach, but as mudslides often pull trash from other parts of the coastline, it's not just the beaches that can affect the oceans.

"Turtle Sanctuary" Our Editor-in-Chief snapped this photo in Aruba. She writes on her blog,"At the top of the steps leading down to this 'sanctuary' was a poster talking about the importance of beaches like these in the Arikok National Park to breeding sea turtles." "When I went down to the beach, I found a headless doll, plastic bottles, flip-flops, a sneaker -- it was a joke how much garbage was there." NEWS: Pacific Plastic Soup 100-fold Increase

Goa, India It's not just the West where trash can collect on the beaches. Here a beach in Goa, India, garbage and litter from plastic and glass lie entangled in vegetation. If washed into the ocean, the glass will eventually break down and return to sand, but the plastic will live for hundreds of thousands of years, likely finding its way to the "Great Pacific Patch."

Isle of Skye Trash dropped from one beach can find its way to other, more visible places than the Pacific Garbage Patch. Here, a beach on the Isle of Skye in Scotland is covered in trash that washed ashore. ANALYSIS: Antarctic Garbage Patch Coming?

Hidden Trash Even if we attempt to dispose of our trash "properly" we can still affect the world's oceans. Plastic bags concealed in an old landfill are revealed as the edge is eroded away. This island in the United Kingdom will eventually begin to lose its long-hidden trash into the sea. Then, as sea levels rise around the world and weather becomes stormier, many areas with landfills near the water will do the same as they experience greater rates of coastal erosion.

Passing on the Trash This small island in the Philippines is an attractive island, but it doesn't keep it from accumulating trash. If the residents of Hong Kong fail to clean the pellets from their beaches, the Olympic crowds toss their trash in the wrong place, or a storm washes plastic into the seas off California, eventually it will end up tainting these pristine beaches. If we're not careful, instead of digging for coins and enjoying a days catch on a beach vacation, we'll be digging for old water bottles and eating a fish that consumed those pellets.

It’s Memorial Day weekend, which means many of us will be headed to the nearest beach, pool or otherwise sunny location, if we’re lucky enough to have sun.

But how many of us will put on sunscreen in order to avoid a nasty burn? Not nearly enough of us, says the Centers for Disease Control and Prevention.

In a study of self-reported lifestyle choices of 4,000 adults, under a third reported using sunscreen regularly.

The study, published recently in the Journal of the American Academy of Dermatology, found that 14 percent of men and 30 percent of women said they used sunscreen on their faces. Before we jump all over the guys, the number of women may be higher because many women’s facial creams contain sunscreen.

More than 42 percent of men and 27 percent of women reported that they never used sunscreen on the rest of their bodies.

And of those who said they regularly used sunscreen, nearly 40 percent didn’t know whether the sunscreen they used was broad spectrum, blocking both UVA and UVB rays.

According to an American Council on Science and Health press release, “Skin cancer (including basal cell carcinoma) is the most common of all cancers, and the number of cases continues to rise.

“About 3.5 million cases of skin cancer are diagnosed every year. Melanoma, the most dangerous and potentially deadly type of skin cancer, will account for over 70,000 cases in 2015. Most skin cancers are caused by exposure to the sun — and this exposure can be lessened by sunscreen use.”

The ACSH has a nifty pagethat gives tips on how to stay safe in the summer sun, including wearing hats and glasses and staying out of the sun during its strong times of the day, between 10 and 2.

Be careful out there.
