I once went surfing in Llangennith (Gower, Wales) and there was a brown foam on the water.
I had a nasty gastric infection for 3 weeks and couldn't eat anything. I lost 2 1/2 stone in those 3 weeks.
There were a couple of cases in Swansea of an unknown allergic reaction to some pollution that left some surfers paralised from the neck down for a couple of weeks!!
I agree that man is systematically destroying everything. If you take a look at the SAS (Surfers Against Sewage) site it states that 300,000,000 tonnes of raw or partially treated sewage are pumped into the sea around the british isles EVERY DAY!!
