First-of-its-Kind Map Details Extent of Plastic in Five Ocean Gyres
When a research team set sail on a nine-month, worldwide expedition in 2010 to study the impact of global warming on Earth's oceans, one of their projects was to locate the accumulations of plastic.
They found plenty. They explored the five huge gyres, which collectively contain tens of thousands of tons of plastic. The result was the creation of a compelling, first-of-its-kind map of this debris.
But in the process, they realized that the plastic in the gyres didn't begin to account for the enormous amount of plastic that's been manufactured since the mass production of plastic began in the mid 1940s.
"Our observations show that large loads of plastic fragments, with sizes from microns to some millimeters, are unaccounted for in the surface loads. But we don't know what this plastic is doing. The plastic is somewhere—in the ocean life, in the depths or broken down into fine particles undetectable by nets."
While there's been considerable alarm raised about these gyres of floating plastic, the missing plastic could be having negative impacts we don't yet know about. As National Geographic reports, the study of marine plastic debris is new, dating back only to 2004, when British marine biologist Richard Thompson concluded that most ocean debris is, in fact, plastic.

The discovery of the missing plastic raises a host of questions. Oceanographer Kara Lavender Law of the Cape Cod-based Sea Education Association, part of a team currently researching issues surrounding marine debris, told National Geographic:
"We are at the very early stages of understanding the accounting. If we think ten or a hundred times more plastic is entering the ocean than we can account for, then where is it? We still haven't answered that question. And if we don't know where it is or how it is impacting organisms, we can't tell the person on the street how big the problem is."
Among the possibilities: it's being consumed by small fish that are eaten by larger fish caught for human consumption, such as tuna and swordfish, and ending up in the human food system. Or it could be finding its way into the ecosystem of the world's least explored region, the deep ocean.
"Sadly, the accumulation of plastic in the deep ocean would be modifying this enigmatic ecosystem before we can really know it," said Cozar.

No matter the time of year, there's always a point in each season when my skin decides to cause me issues. While these skin issues can vary, I find the most common issues to be dryness, acne and redness.

Now, correspondence obtained by the LA Times revealed just how deeply involved industry lobbyists and a controversial, industry-funded toxicologist were in drafting the federal agency's proposal to scrap its current, protective approach to regulating toxin exposure.
February 22 is the birthday of conservationist and beloved TV personality "Crocodile Hunter" Steve Irwin, who would have been 57 years old today.
Irwin's life was tragically cut short when the barb from a stingray went through his chest while he was filming in 2006, but his legacy of loving and protecting wildlife lives on, most recently in a Google Doodle today honoring his birthday.

That video showed the extrusion of a bubblegum-pink substance oozing into a coiled pile, something between Play-Doh, sausage and soft-serve strawberry ice cream. Branded "pink slime"—the name came from an email sent by a USDA microbiologist in 2002—this stuff was actually beef, destined for supermarkets and fast-food burgers.
'Kicking Ass for Her Generation': Applause for 16-Year-Old Greta Thunberg as EU Chief Pledges Billions to Curb Climate Threat

Sixteen-year-old climate action leader Greta Thunberg stood alongside European Commission President Jean-Claude Juncker Thursday in Brussels as he indicated—after weeks of climate strikes around the world inspired by the Swedish teenager—that the European Union has heard the demands of young people and pledged a quarter of $1 trillion budget over the next seven years to address the crisis of a rapidly heating planet.
In the financial period beginning in 2021, Juncker said, the EU will devote a quarter of its budget to solving the crisis.
