Barrier to Stop Plastic Waste From Reaching the Sea Launches in Amsterdam
The scourge of plastic waste that washes up on once-pristine beaches and finds its way into the middle of the ocean often starts on land, is dumped in rivers and canals, and gets carried out to sea. At the current rate, marine plastic is predicted to outweigh all the fish in the seas by 2050, according to Silicon Canals.
Now, a Dutch start-up has launched a barrier device to remove plastic from canals and rivers while allowing fish to swim right through, as The Guardian reported.
The Great Bubble Barrier, an innovative start-up, teamed up with the Amsterdam municipal government and the regional water board to launch their device last week in Amsterdam's Westerdok Canal, at the tip of city's historic canal belt. The canal is an ideal starting point since it empties into the IJ river, which feeds the North Sea Canal and then the North Sea, as Silicon Canals reported.
"This is an important milestone," said Francis Zoet, co-founder of The Great Bubble Barrier start-up, as DutchNews reported. "This is the first project that is going to stop plastic from ending up in the sea."
The device consists of a pipe nearly 200 feet long that is punctured with holes and laid at the bottom of the canal. It sits at the canal bed on a diagonal line. Compressed air is pumped into the pipe, which then forms bubbles as it leaves. Since it is positioned diagonally, pieces of plastic are pushed toward the side of the canal by the bubbles. Then a floating platform captures the litter, as DutchNews reported.
Preliminary tests of the project, which has taken three years, show that the device is capable of ushering 80 percent of the canal's plastic waste to its banks. Furthermore, it works 24 hours a day and does not interfere with shipping or wildlife, according to The Great Bubble Barrier.
"More than two-thirds of plastics in the ocean comes out of rivers and canals – so if you have to intercept it, why not do it in the rivers?" said Philip Ehrhorn, co-inventor of the technology, as The Guardian reported. "You can't put a physical barrier in a canal: it has to be open for wildlife and recreation."
The Great Bubble Barrier will supplement current cleanup efforts in Amsterdam. Each year, a team of five garbage boats removes nearly 92,600 pounds of trash from the city's waterways, but small pieces of trash and plastic at the bottom of the canals simply slip through the nets.
"Plastic in our water is becoming an increasing problem [and] has profound effects on the quality of our water and therefore on everything that lives in or near the water," said Sander Mager, a board member of The Great Bubble Barrier, at the launch, as DutchNews reported. "This is precisely why it is important for the water management board to collaborate intensively with others to make a stand against this socially urgent problem."
The trash collected by The Great Bubble Barrier will be collected separately from what the garbage boats collect. The plastics action group Schone Rivieren, which translates to Clean Rivers, will analyze the waste.
"Amsterdam's canals have enormous appeal," said Marieke van Doorninck, head of sustainability for Amsterdam council, as The Guardian reported. "But when you think of them, you don't think about plastic bottles and bags in the water. The bubble barrier will mean fewer plastics reach the ocean, and is a step towards better regulation of our ecosystem, to the benefit of man, beast and environment."

Four years ago, Jacob Abel cast his first presidential vote for Donald Trump. As a young conservative from Concord, North Carolina, the choice felt natural.
But this November, he plans to cast a "protest vote" for a write-in candidate or abstain from casting a ballot for president. A determining factor in his 180-degree turn? Climate change.
Fractures Among Young Climate Conservatives<p>While young conservatives have united around the urgency of climate change, they remain divided over how to bring their concerns to the ballot box. Some embrace right-wing <a href="https://www.washingtonpost.com/politics/biden-attacks-republican-convention/2020/08/24/434e5b46-e66d-11ea-970a-64c73a1c2392_story.html" target="_blank">attacks</a> painting Biden as a "tool of the left" and find his climate agenda "radical."

The GOP is failing to "meet the moment" for climate action, Mann said.

A False Equivalency<p>Young climate conservatives may fear climate denial and delayed climate action, but more than that, they fear the growing political momentum around the Green New Deal, the massive spending it entails and <a href="https://joebiden.com/climate-plan/" target="_blank">Biden's citing of it</a> as a "crucial framing for meeting the climate challenges we face."</p><p>Many don't want to split with their party to support a Democrat whose <a href="https://www.npr.org/2019/09/03/757220130/joe-biden-on-bipartisanship-gun-control-and-regrets-over-inaction-after-a-traged" target="_blank">allegedly bipartisan intentions</a> they doubt. If stymieing what they consider a radical green agenda means re-electing a climate change denying president, so be it. </p><p>"I'm scared of climate change, but I'm also scared of the Green New Deal and what it means for America," said Ben Mutolo, a republicEN spokesperson and junior at SUNY College of Environmental Science and Forestry. </p><p>Mutolo felt encouraged by former Ohio Governor John Kasich's <a href="https://www.rollcall.com/2020/08/17/kasich-speech-to-democratic-convention-follows-years-of-building-conservative-credentials/" target="_blank" rel="noopener noreferrer">appearance</a> at the Democratic National Convention, but he still struggles to see himself voting for Biden.

In the face of dangerous heat waves this summer, Americans have taken shelter in air conditioned cooling centers. Normally, that would be a wise choice, but during a pandemic, indoor shelters present new risks. The same air conditioning systems that keep us cool recirculate air around us, potentially spreading the coronavirus.
