Yesterday was day 10 of my pledge and I was back on the House Reef doing a navigation dive with Advanced Open Water students so whilst they were trying to pick there way through the corals and find the way back to the boat I picked up trash behind them - and I did pretty well: 13 plastic bottles, 9 food containers, 1 metal beverage can, 3 plastic bags and a broken snorkel holder. I also got a bit of a surprise when I found a crocodile fish hiding behind one of the bottles! :-)
