In June 2006 a United Nations Environmental Program report estimated that there is an average of 46, 000 pieces of plasticdebris in every square mile of ocean.
In New Zealand Scion Research works to convert the waste stream from pulp and paper processing into a blend of microbial cell wall debris and plastic called polyhydroxyalkanoate, or PHA. Plant a PHA flower pot into the ground and and it biodegrades.
Approximately 60 to 80 percent of marine debris is plastic, the majority of which is as a result of our mindless use of one-life plastics, 60 percent of which is comprised of plastic bags, Styrofoam (used for take away foods), drinks bottles and their caps.
