In the Netherlands, architects are launching an ambitious plan to stop plastic pollution from clogging up the North Sea.
One of the challenges of cleaning up the billions of pieces of plastic in the world's oceans is that the fragments are so small. Water bottles and plastic bags eventually break apart into tinier and tinier pieces that spread throughout the water in a messy soup. While the ideal solution might be making sure plastic makes it to recycling bins--or actually using fewer plastic products--another approach is to do a better job of catching plastic trash just before it reaches the sea.
