> is aluminum in the ocean an ecological problem in the way plastics are? It depend a bit on how one want to measure it. Imagine walking in a forest and for every 10 step you see a can laying on the ground. Would that be a ecological problem? Cans and bottles are often home to a lot of insect and other small animals so there could be an argument that in terms of ecology it is beneficial. The other side of the argument say that any such man made littering is harmful, and since they do not really decompose at a fast pace, its a problem that steadily increase each year. The only trash that realistically get removed from the ocean floor is by divers, generally as a hobby, which is only a tiny sliver of all trash that do end up in the ocean floor. The rest accumulate and do so at an increased rate.
