This is a bit strange given all the so called environment experts.

Unwanted sound, or noise, can have a large impact on the marine environment, because noise can blanket a very large area, potentially preventing fish or whales from hearing their prey or predators, finding their way, or connecting with mates, group members, or their young.NOISE POLLUTION as well John,good post

good that the pollution media never cottoned on to what we had to do in the '60's and '70's. say no more .

The world is definitely changing, I know that the Southern States in America have always had Tornadoes, but I don't think to the extent they are having them today, I mean they are simply flattening everything before them. Now that post by John blaming shipping, I wonder if some investors are trying to divert attention from Airplanes, the amount of pollution they produce flying in their thousands every day of the year must be tremendous.

Des, there are many now, often in high places, who follow and use the Climate Change Cul to their advantage.
This could well be another case.

As to Ocean pollution, nothing like it was in our day when so much went over the wall, all manner of crap along with bits, such as silver salvers, which should have not.
Far too valuable particularly in Las Palmas, one could buy you 200 smokes.

I don't remember anything that didn't go over the wall. Maybe it's those years of iron ships that have caused all the environmental problems?
Maybe it's not todays ship that are to blame?

#2 As regards whales and noise , the enforcement for that has been years in the program even before climate change and pollution was ever mentioned. All seismic ships are barred from setting off under water explosions which are vital for exploration when there are whales in the vicinity.
To enforce this law in Australia at least seismic ships carry government inspectors to see it is carried out. Cheers JS

My first experience of non pollution was up the Great Lakes of Canada in 1968. Where there were no overboard discharges . If ship did not have a sewage tank then too bad , ships toilets were sealed and ship had to hire chemical toilets in their place. The fresh water lakes were that pure we used to use for drinking water. Extremely high fines for anyone not complying with these laws was in trouble. Even before entering the seaway if arrived in Montreal with empty garbage drums the authorities assumed you had dumped them on the river passage and were fined , so even before entering the lakes you had plenty of forewarning of the consequences. What the lakes are like today I wouldn’t have a clue but as said we used as drinking water in those days and can’t recollect anyone catching Cholera. Maybe the nearest to it was a dirty beer glass ashore. Cheers JS.

#1 That should be not too hard to measure John , after all someone has to know how to measure the correction for refraction to put in Nautical Tables for taken sights etc. whenever climate change and its causes are shouted about any other sources of the earth heating is not always heard as are shouted down by those who opened their own theories earlier on. Other sources of heating rarely get hearing space. The dirtiest water to drink to my mind is direct rainwater as is contaminated by every piece of bacteria in the atmosphere before going down one’s neck. Water drank from streams is much purer has had the advantage of running and being filtered to a certain extent. JS

I can remember on a City boat, going through the red sea and beyond. The blokes in the engine room would bring up these 40 gallon drums of horrible looking oil, and tip them out into the sea, (not the drums). We had loads of new oil in drums tied up on deck, which they were using every day. We broke down every day for hours on end. We ended up anchored in Aden I think, where they had labour come aboard clearing all this sooty stuff. There were hundreds of them, sort of coolie looking people, with baskets on their heads, tipping this stuff into the sea, a constant line, up and down the engine room. I don't know anything about ships engines, but there was something wrong down below. We stayed there for ages getting things fixed, can't remember how long, days, weeks.
Add that lot to all the paint chipping we used to chuck over the wall, plus all the toilet stuff, we made our contribution to the environment well enough.
