On May 23rd, World Turtle Day, the Mediterranean Association to Save the Sea Turtles (Medasset, the international NGO founded in 1988) launched an awareness raising campaign on the Athens railways and tramways about the devastating effects of plastic, especially plastic bags, to marine life: \"You See the Difference.A Turtle Does Not\". The ad was also posted on Facebook and in a matter of hours it went viral, shared by tens of thousands of people from New York to Thailand, Egypt, Turkey, Brazil, Australia and throughout Europe. The issue of plastic litter in our seas, and especially plastic bags that sea turtles often mistake for food, appears to resonate with people who flooded Facebook with comments and requests to share the ad in their communities. Plastic in our seas is killing thousands of sea turtles, sea birds and other marine life each year, as they often mistake it for food. Medasset urges everyone to adopt habits that minimise the use of plastic. Consider using a reusable bag when shopping, avoid single-use plastic items, look for products and packaging made from renewable resources, choose products with the least plastic packaging and recycle what you can\'t refuse.
