The UNEP Year Book 2011 - Emerging Issues in Our Changing Global Environment - was launched recently. It is the 8th edition of the UNEP flagship report which examines global emerging issues and provides the latest environmental science. It also highlights major environmental events and developments over the past year, and presents the most recent data and indicator trends. As the ocean has become a global repository for much of the waste we produce, marine litter (plastic debris) has been included as an issue in this Year Book for the first time. NOWPAP Scientific Affairs Officer has participated in the drafting team and contributed as one of the co-authors of that chapter.
