Do any sea sports pollute the sea?

All sports that involve any vehicle pollute.  I pollute the water by surfing really, because I drive to the ocean whenever I go, and my car unfortunately has very serious negative effects on the ocean and waterways.  Also, when my board finally reaches the end of the road (after it has been sold, then given away twice, and eventually is considered worthless) it will likely end up in a landfill or something.

No it is not \n\ntoo much of some fish can lead to a mercury accumulation because the ocean is so contaminated but you would have to eat an awful amount - you are not a seal are you?

The soap has phosphate and nitrate salts that help to growth of aquatic plants in marine. increasing the growth of them will increase consuming of water oxygen,therefor the life of aquatic animals should be in hazard.

yes there are certain chemicals that when placed in a bay can effect salinity levels in that bay, which will actually vary the temperature of the water causing native fish and sea life to leave.

Its not.  What you see on top of water is hydrocarbon polution.  most really deadly polutants such as hexa valent chromium deposit in the river bed or lake floor and continue to contaminate the water for several years.

no doubt, disposal of nuclear under the sea in not the safer solution. lead blocks can not be stable for years together . if possible it will never withstand for 1000 years . so there will be dangerous radiations raniating which will affect aquatic organisms & later pollute the atmosphere

they don't actually use ping pong balls, but yes, you pump ping pong balls down from the surface one at a time, and that fills the ship with air.\nhere is a link to some facts about somebody who did it.

the ocean is salty as it contains water colected from different sources such as rivers which bring with them different types of mineral salts before they mingle with the ocean.

Is the match on water or on land?

yes.  saltwater is salty, meaning it has a lot of ions.  Lots of ions conduct electricity.

There is no corolation with oceans having high and low tides and blood pressure.  Moving water, however, does create negative ions which have been proven to make people feel better.  May be a distant thought behind that.\n\nSome people call the rise and fall of blood bressure "tides."  This may be where you have heard of a relation.
