5 Gyres Institute Sets Sail to Study Plastic Pollution in Lake Michigan
Today, a team from 5 Gyres Institute launched an unprecedented expedition to quantify and report on the extent of plastic pollution in Lake Michigan.
The survey, funded in part by the Burning River Foundation and Illinois-Indiana Sea Grant, has been broken into three legs for the first three weeks of August. Despite volumes of anecdotal evidence, to date no validated attempt has been made to study the severity of plastics in all of the Great Lakes. Though public awareness is growing about the pervasive plastic problem in the world’s oceans, 5 Gyres has shown that plastic pollution is affecting upstream, fresh water systems as well.
In August of 2012, staff from 5 Gyres Institute sailed Lakes Superior, Huron and Erie, completing the first ever plastic pollution survey in the Great Lakes, discovering some of the highest concentrations of plastic particles ever recorded in any aquatic environment, fresh or saltwater. The findings of the first expedition are documented in the first scientific research paper on the subject, which has been submitted for peer-review. The publication of the paper is anticipated within the coming months.
5 Gyres Institute, with researchers from the State University of New York-Fredonia (SUNY-Fredonia), are spending August accumulating detailed samples from Lake Michigan in order to determine the surface density of plastic pollution, the type of plastics found and the chemical uptake of persistent organic pollutants absorbed by plastic.
“Having been the first and only group to sail all five of the world’s oceans conducting similar research on plastic pollution, we’ve turned our attention to these important freshwater ecosystems," says Dr. Marcus Eriksen, co-founder and research director of 5 Gyres Institute. "In the oceans, we know that base food chain fish eat toxin-laden plastics and that humans are often the apex predator of that food system. This makes us curious about how plastics may be affecting freshwater species, and ultimately, us.”
Last year, the 5 Gyres Institute made a startling discovery in samples taken from Lakes Superior, Huron and Erie that lead to a massive corporate campaign to prevent plastics from reaching watersheds. In Lake Erie, the 5 Gyres team found more than 450,000 micro polyethylene beads per square kilometer, the same beads employed in personal care products as an exfoliant. Health and beauty products containing plastic micro-beads that are bought by the general public are designed to be washed down the drain as they are rinsed from the face and body. The plastic micro-beads are too small to be adequately captured by wastewater treatment.
These findings lead the 5 Gyres Institute to launch massive grassroots campaigns asking the producers of these products to eliminate plastic micro-beads in favor of available, natural alternatives. After reporting their scientific findings to companies that utilize micro-beads, the 5 Gyres Insitute has won several key victories that will help protect the Great Lakes ecosystem. Johnson & Johnson, L’Oreal, The Body Shop and Colgate-Palmolive have all pledged to remove these synthetic beads from their products by 2015. The 5 Gyres Institute has also received a pledge from Proctor & Gamble to phase out these beads by 2017, but the campaigning for an earlier phase-out continues.

One hundred seconds to midnight. That's how close humanity is to the apocalypse, and it's as close as the world has ever been, according to Wednesday's annual announcement from the Bulletin of the Atomic Scientists, a group that has been running its "Doomsday Clock" since the early years of the nuclear age in 1947.

The majority of Americans are stressed, sleep-deprived and overweight and suffer from largely preventable lifestyle diseases such as heart disease, cancer, stroke and diabetes. Being overweight or obese contributes to the 50% of adults who suffer high blood pressure, 10% with diabetes and additional 35% with pre-diabetes. And the costs are unaffordable and growing. About 90% of the nearly $4 trillion Americans spend annually for health care in the U.S. is for chronic diseases and mental health conditions. But there are new lifestyle "medicines" that are free that doctors could be prescribing for all their patients.
Taking an unconventional approach to conduct the largest-ever poll on climate change, the United Nations' Development Program and the University of Oxford surveyed 1.2 million people across 50 countries from October to December of 2020 through ads distributed in mobile gaming apps.

Fall used to be the time when millions of monarch butterflies in North America would journey upwards of 2,000 miles to warmer winter habitat.
