At first I was so happy to find this cute sea horse all alone but as the tide changed, sea grass and debris started to drift over the reef – and plastic, trash and sewage along with it. The white blobs you see in the background are actually plastic bags. As the whole thing unfolded, I knew it was an important scene that had to be documented. It was frustrating, disgusting and sad but I had to shoot it. Photo by Justin Hofman
