Microplastics have been found in rain, Arctic ice cores, inside the fish we eat, as well as in fruit and vegetables. New research suggests 136,000 tons of microplastics are ejected from the ocean each year, ending up in the air we breathe. They are in human placentas, our wastewater, and our drinking water.
Microplastics in Ocean
More than 90% of the microplastics found were fibres and, among them, rayon (54%) and acrylic (24%) – both of which are commonly used in clothing – were the most abundant.
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..
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.
