ENCINITAS, Calif. (FOX 5/KUSI) -- Whether it’s sunglasses, a water bottle, or a TV remote, almost everything is made out of plastic. But how is most plastic assembled? “It’s easier to ship a lot of something very small instead of big pieces, so they’re made into these little nurdles," said Mark O’Connor, Surfrider Foundation's "Rise Above Plastics" program co-lead. They are transported around the world by trains and boats and then melted into their final form. But many nurdles do not make it to their intended destination. Instead, they end up on San Diego's beaches. “The first time you’re like, 'Oh, I’ve never seen one!' And then you see one. All of a sudden they just start popping up. You can’t not see them,” O’Connor said.  “When I realized there were some right here in Carlsbad where I clean the beach just down the street, that was pretty surprising to me,” said Janis Jones, the program's co-lead. Jones says a large number of nurdles are spilling out of train cars during shipping, eventually making their way to the beach. “In this one small area, I couldn’t even begin to count them,” said Jones in front of the Carlsbad train station. The Plastic Pellet Free Waters Act is legislation introduced by Congressman Mike Levin that would tighten regulations on shipping plastic. However, some advocates say the current legislation needs more work. “It’s not saying that the IMDG code for nurdles needs to be changed to hazardous material,” said Clare Swithenbank-Bowman, the founder of Trash4Tokens and Litter4Tokens. Swithenbank-Bowman is pushing for the draft to include a hazardous material classification for nurdles in order to prevent spills, but without that amendment… “It wouldn’t stop it because they’re not going to be in sealed containers like oil,” said Swithenbank-Bowman. For safety reasons, advocates are asking the public not to try to pick up nurdles in the area by the train tracks, but to do so at the beach.
