For example, rock layers show the sequence of geological events, and the presence and amount of radioactive elements in rocks make it possible to determine their ages. Analyses of rock formations and the fossil record are used to establish relative ages. In an undisturbed column of rock, the youngest rocks are at the top, and the oldest are at the bottom. Rock layers have sometimes been rearranged by tectonic forces; rearrangements can be seen or inferred, such as from inverted sequences of fossil types.
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.News Dive into the world of science!
