What we found out is that about one in five users disposes of the contact lenses by throwing them into the bathroom sink or in the toilet, lead author Rolf Halden, director of the university's Center for Environmental Health Engineering, said Monday at a news conference at a meeting of the American Chemical Society.The study was presented at the meeting but has not been published or peer-reviewed, which are considered a gold standard in medical and scientific research.After being flushed, the lenses float through the wastewater system to sewage treatment plants. Halden said the researchers tested 11 brands of contacts and found that they don't degrade during the treatment process but tear into smaller and smaller pieces.The fragments are heavier than water, so they settle into the treated sewage sludge, which is often spread on land. The lenses can then make their way into rivers, lakes and the ocean through runoff."It sounds like a very small problem, because the lenses themselves are tiny, but they come by the billions," Halden said. The study estimated that about 45 million people wear contact lenses in the US alone."What we find is that there are billions of lenses ending up in US wastewater every year. They contribute a load of at least 20,000 kilograms per year of contact lenses," Halden said. That's between 6 and 10 metric tons of lenses, according to the study.Study co-author Charlie Rolsky said contact lenses are different than short-use plastics like straws, plastic bags or styrofoam because they are so important to people who wear them."It is a very personal high-value plastic that people sort of take for granted and utilize every day of their lives," Rolsky said.Halden said people don't think of the lenses as plastic waste because they feel like fluid, almost like water. They even come in tiny packets of saline solution.But even people who describe themselves as environmentally conscious admitted flushing their lenses, he noted."We have created an almost immortal material. It does not go away. It does not biodegrade," Halden said.This is a good thing when it comes to contact lenses, because, he said, you don't want them to degrade in the user's eye, which could impair vision or become a breeding ground for bacteria.Contact lenses are a small part of the pollution problem, Rolsky said, but he hopes that the findings encourage people to think more about how to get rid of plastic waste."This might have been a different experiment had there been labeling on a lot of these boxes sort of specifying 'maybe dispose of these with solid waste and please avoid having them go down a drain'; maybe it would be a different story," he said.Contact wearers should throw their lenses in the trash or recycle them, the researchers advise. 2779

We've always acted as if black lives never mattered, as if people of color never mattered,"" Susan Bro, the mother of the counterprotester killed in Charlottesville last year, told CNN's Anderson Cooper on Friday. ""We really have not treated people of color in the same way we ourselves want to be treated. And I'm calling b.s. on that.""As many as 400 people are expected to attend Sunday's white nationalist demonstration, according to the event's permit application submitted by Jason Kessler, the same person who organized last year's ""Unite the Right"" rally in opposition to the renaming of two parks honoring Confederate generals.That event included white nationalists, neo-Nazis and members of the Ku Klux Klan.Participants are expected to gather at Washington's Foggy Bottom subway station at 5 p.m. ET before marching to Lafayette Square park, across the street from the White House, according to the permit application.They won't be alone. A series of counterprotests are planned in Washington throughout the day, led by members of 40 anti-racism groups. The Shut it Down D.C. Coalition, for example, scheduled its own rally beginning at noon to counter ""Unite the Right 2.""Photos: 'Unite the Right' white supremacist protest and counterprotest in Washington, D.C.Black Lives Matter DC is hosting the ""Rise Up Fight Back Counter-Protest"" between 2 and 7 p.m., just a block away from where ""Unite the Right 2"" is set to take place.In the past, similar far-right demonstrations have been dwarfed by counterprotests.For example, at a a separate Ku Klux Klan gathering in Charlottesville in July 2017, where Klansmen were outnumbered 20 to 1, according to Charlottesville officials.Sunday's rallies come at a time when the wounds from last year's clash in Charlottesville remain raw, particularly in regards to the death of counterprotester Heather Heyer, who was killed when a suspected neo-Nazi sympathizer drove a car into a crowd.Metropolitan Police Chief Peter Newsham said officers will endeavor to keep far-right demonstrators and counterprotesters separate from one another. Guns will be forbidden near the rally site, regardless of whether an individual has a permit to carry the firearm.""Our role is to make sure we have a First Amendment event that goes on without any types of violence or destruction of property,"" Newsham said at a Monday news conference, according to CNN affiliate WTOP. ""We intend to have the entire police department engaged to make sure that we handle this type of thing.""""As the nation's capital, we host millions of visitors each year,"" said DC Mayor Muriel Bowser, a Democrat, in a statement. ""Fortunately, very, very few share the views that will be expressed in Lafayette Park on Sunday.""""Washington, DC, is a city of love, inclusion and diversity,"" she continued, ""and -- like millions of Americans across the nation -- we know that the people who are coming here to profess hate and sow division are wrong.""" 2968

WASHINGTON (AP) - President Donald Trump and Supreme Court Chief Justice John Roberts are engaging in an extraordinary public dispute over the independence of America's judiciary, with Roberts bluntly rebuking the president for denouncing a judge who rejected Trump's migrant asylum policy as an "Obama judge." 310

We sell out every year, and this year's event is very different than last year. Because we're seeing lots of growth in the area, next year's event will be much more different, Lannom told 10News. 195
