Bubble Barrier Stopping Plastic Trash in River Streams

According to the University of California, in 1950 the world produced about two million tons of plastic products. By 2015 the production increased to 380 million tons. If it continues at this pace by 2050 the weight of plastic waste in the world’s oceans may equal that of all fish. Researchers in the Netherlands say they have found an efficient and environmentally safe way for stopping plastic trash floating in rivers from entering our oceans: Bubbles.
