Ocean Pollution


In many ways, the ocean mirrors its surroundings. When the sea is glassy and still, its surface captivates with the images it holds. Sadly, scientists and sea goers alike are now finding a dismal portrait of human activity reflected in our waters—pollution.

The vast majority of ocean pollution begins on land: agricultural run-off such as herbicides, pesticides, and excess nutrients cause dead zones. Sewage, pharmaceuticals, plastics, and heavy metals such as mercury also run from land to sea.

Mercury, a neurotoxin, enters the environment through coal burning power plants. Since the industrial revolution, mercury near the ocean’s surface has nearly tripled. Mercury is not diluted or degraded in the ocean over time. Instead it bioaccumulates, increasing in concentration as it moves up the food chain. High concentrations of mercury in seafood pose a risk to human health.

Another concerning pollutant is plastic, which accounts for about 73% of marine debris. Reaching every corner of the globe, plastic litter has accumulated in remote regions of the Arctic as well as in the swirling garbage patches of the Pacific and Atlantic Ocean. Plastic litter and fishing gear entangle whales and dolphins while also killing sea turtles and birds that mistake debris for food.

Over time, plastics break down into microplastics; The full effect on marine organisms is not yet known. Studies have shown that microplastics negatively affect animals’ growth and reproduction. And, recently, a study on hermit crabs revealed that microplastic exposure inhibited crabs’ ability to choose a suitable shell—evidence of how all life is growing increasingly vulnerable as a result of plastic waste.

Fossil fuels are the common thread in this web of pollution that ensnares marine life. Currently, plastics consume 14% of the world’s oil and gas. For the U.S. fracking boom has infused the industry with a cheap source of ethylene, a key ingredient of plastics.

Only about 10% of plastics will be recycled, the rest will go to landfills, be incinerated, or make their way into our environment. Incineration facilities may get rid of the visible waste, but they release thousands of pollutants into the air as the trash burns. These toxic facilities are disproportionately built in communities of color. So, in short, pollution needs to stop at its primary source: polluting activities and industries

As sea levels rise and flooding increases, more and more pollutants will wash into our waterways and seas. As pollutants enter our oceans, they promise to reflect our waste long after our lives.

Instead of a mass influx of plastic and toxins, the RCC hopes to leave a better story written in the waves and the chemistry of the deep sea. That is why the RCC is committed to tackling pollution by advocating for a clean energy future, environmental justice, and protection for marine ecosystems.

How a shocking environmental disaster was uncovered off the California coast after 70 years
Just 10 miles off the coast of Los Angeles lurks an environmental disaster over 70 years in the making, which few have ever heard about. That is, until now, thanks to the research of a University of California marine scientist named David Valentine. Working with little more than rumors and a hunch, curiosity guided him 3,000 feet below the ocean’s surface. A few hours of research time and an autonomous robotic submersible unearthed what had been hidden since the 1940s: countless barrels of toxic waste, laced with DDT, littering the ocean floor in between Long Beach and Catalina Island.

The ocean is a giant dump for chemical weapons. Can we clean it up before it’s too late?
Millions of tons of discarded chemical munitions lie scattered across every ocean on the planet. Can we disband this pollution ticking time bomb before it explodes? Almost seventy years ago, a group of Polish children arrived in the coastal village of Darłowo for summer camp. As some children splashed in the cold, turbid waters of the Baltic Sea, others played around an old, corroded barrel they found lodged on the beach, blissfully unaware of the looming threat leaking from within. A few hours after being exposed to the barrel’s brown-black liquid, over 100 children began feeling sick. The culprit? Mustard gas. Read more

Florida officials scramble to prevent ‘catastrophic flood’ of contaminated water from leaking reservoir
Florida officials were scrambling Sunday to prevent a “catastrophic flood” after the lining in a reservoir holding hundreds of millions of gallons of wastewater sprang a leak. They warned that the breached reservoir’s total collapse could send a 20-foot wall of contaminated water crashing down into the surrounding area. Read more
