The Oceana report found that in the reported cases, 90 percent of the animals had swallowed plastic, and the rest were entangled in it. Necropsies often showed that the animals had died from blockages or lacerations. Other times, ingesting plastic may have simply weakened the animal or played no role in its death. Over all, in 82 percent of the cases, the animals died..
Microplastics in Ocean
It’s been calculated that something in the order of four to 12 million tonnes of plastic waste enter the oceans every year, mostly through rivers.
What we commonly see accumulating at the sea surface is “less than the tip of the iceberg, maybe a half of 1% of the total,” says Erik Van Sebille, an oceanographer at Utrecht University in the Netherlands.
Wildlife around the world is exposed to plastic pollutants called endocrine-disrupting chemicals (EDCs). Not much is known about how these chemicals affect marine environments, though scientists have been studying them for years. According to The Guardian, killer whales, for instance,… Read More ›
Most of the trash in the ocean comes from land, and most of it is plastic. An estimated 4.8 to 12.7 million tons of plastic leaves the shorelines into the ocean globally each year, and there are now over 5.25 trillion pieces of plastic are floating in the ocean currently.
And our planet’s modifier is in trouble. It’s a Neptune 911 crisis. What can we do to combat our ocean’s struggle with marine debris, hypoxia and acidification? The answers are found in university labs, recognized in world organizations, and ignored by feckless politicians and leaders.
She says understanding how plastic gets into fish matters not just to the fish, but to us. “We eat fish that eat plastic,” she says. “Are there things that transfer to the tissue? Does the plastic itself transfer to the tissue? Do the chemicals associated with the plastic transfer to the tissue?”
Prevention starts when consumers refuse to use plastic, or lawmakers try to ban it bag by bag. Also following the adage of reduce, reuse, and recycle what you don’t refuse. But much of the trash that comes ashore appears to come from foreign places or as the detritus from industries notorious for ocean litter.
