Heavy metals including mercury, lead, cadmium, copper, nickel, chromium, and zinc in the contaminated soil have adverse health effects in human metabolism. Ingestion, contact through skin, diet through the soil-food chain, respiratory intake, and oral intake can deliver the toxic substances to human beings.
When The Mermaids Cry: Introduction The world population is living, working, vacationing, increasingly conglomerating along the coasts, and standing on the front row of the greatest, most unprecedented, plastic waste tide ever faced.
For more than 50 years, global production and consumption of plastics have continued to rise. An estimated million tons of plastics were produced inrepresenting a 4 percent increase overand confirming and upward trend over the past years. Worldwatch Institute — January Inour global plastic consumption worldwide has been estimated at million tons, and, according to a report by Global Industry Analysts, plastic consumption is to reach Plastic is versatile, lightweight, flexible, moisture resistant, strong, and relatively inexpensive.
Those are the attractive qualities that lead us, around the world, to such a voracious appetite and over-consumption of plastic goods. However, durable and very slow to degrade, plastic materials that are used in the production of so many products all, ultimately, become waste with staying power.
Our tremendous attraction to plastic, coupled with an undeniable behavioral propensity of increasingly over-consuming, discarding, littering and thus polluting, has become a combination of lethal nature. Although inhabited and remote, South Sentinel island is covered with plastic! All over the world the statistics are ever growing, staggeringly.
Tons of plastic debris which by definition are waste that can vary in size from large containers, fishing nets to microscopic plastic pellets or even particles is discarded every year, everywhere, polluting lands, rivers, coasts, beaches, and oceans.
Inthe annual input is estimated to be about twice greater, or 10 bags full of plastic per foot of coastline.
So the cumulative input for would be nearly 20 times the 8 million metric tons estimate — bags of plastic per foot of coastline in the world! Lying halfway between Asia and North America, north of the Hawaiian archipelago, and surrounded by water for thousands of miles on all sides, the Midway Atoll is about as remote as a place can get.
Then, on shore, the spectacle becomes even more poignant, as thousands of bird corpses rest on these beaches, piles of colorful plastic remaining where there stomachs had been. In some cases, the skeleton had entirely biodegraded; yet the stomach-size plastic piles are still present, intact.
Witnesses have watched in horror seabirds choosing plastic pieces, red, pink, brown and blue, because of their similarity to their own food.
It is estimated that of the 1. Albatross, victim of plastic ingestion. From the whale, sea lions, and birds to the microscopic organisms called zooplankton, plastic has been, and is, greatly affecting marine life on shore and off shore.
According to the National Oceanographic and Atmospheric Administration, plastic debris kills an estimatedmarine mammals annually, as well as millions of birds and fishes.
However, most of the littered plastic waste worldwide ultimately ends up at sea. The plastic waste tide we are faced with is not only obvious for us to clearly see washed up on shore or bobbing at sea. Most disconcertingly, the overwhelming amount and mass of marine plastic debris is beyond visual, made of microscopic range fragmented plastic debris that cannot be just scooped out of the ocean.
Extremely littered beach in northern Norway. Some plastic pellets had fragmented to particles thinner than the diameter of a human hair. But while some cannot be seen, those pieces are still there and are still plastic. The study presents an alarming fact: It took at first a magnifying-glass to see the true extent of plastic damage in the North Pacific.
Inside was murky seawater with hundreds of fragmented plastics pieces: All sea creatures, from the largest to the microscopic organisms, are, at one point or another, swallowing the seawater soup instilled with toxic chemicals from plastic decomposition.
In essence, humans are eating their own waste. Manan Vastsyayana The scientists from Project Kaisei and Scripps hope their data gives clues as to the density and extent of these debris, especially since the Great Pacific Garbage Patch might have company in the Southern Hemisphere, where scientists say the gyre is four times bigger.
A plastic-poison has undeniably been instilled by us, prompting an unwilling and illegitimate confrontation of two titans: The crisis is of massive proportion.
The Great Plastic Tide: Magnitude, Scope, Extent A full understanding of the magnitude and scope of this plastic pollution starts with clear definitions as to what and why it is happening. Dimitar Dilkoff Marine Debris The term marine debris has been used for at least 25 years to refer to man-made materials that have been discarded or lost into the ocean.
This workshop came out of a request from the Marine Mammal Commission to the National Marine Fisheries Service to examine the impacts of marine debris.Should Plastic Bags Be Banned?
No because NO,need to ban just reduce the use of plastic. I don't think it using plastic should be banned, but we should reduce the use.
Plastic is necessary and has it's uses, but we could reduce and replace plastic shopping bags, for example, with cloth or brown paper. Our aim should be to seek alternative.
