This photo is of items that were dumped prior to the oceans ant-dumping laws being put into effect.
The scary part is that this means that the tires in the picture have been there for over 30 years and show very little decay in all that time.
Can you imagine the amount of debris and junk including nuclear waste sitting at the bottom of our oceans. The other part of the problem is that although dumping in the oceans has officially stopped (If we cant stop pirates from hi-jacking ocean liners, how are we going to stop illegal dumping?) nobody has worked out how much junk flows into our oceans via polluted river systems.
Just think of the thousands of rivers that flow into the sea and how many cities they pass enroute.
I think its to late to cry for mother earth, its now time to start mourning.
