Research teams at the Danish Golf Union have discovered it takes between 100 to 1,000 years for a golf ball to decompose naturally. A startling fact when it is also estimated 300 million balls are lost or discarded in the United States alone, every year. It seems the simple plastic golf ball is increasingly becoming a major litter problem.
The scale of the dilemma was underlined recently in Scotland, where scientists -- who scoured the watery depths in a submarine hoping to discover evidence of the prehistoric Loch Ness monster -- were surprised to find hundreds of thousands of golf balls lining the bed of the loch.
It was found that during decomposition, the golf balls dissolved to release a high quantity of heavy metals. Dangerous levels of zinc were found in the synthetic rubber filling used in solid core golf balls. When submerged in water, the zinc attached itself to the ground sediment and poisoned the surrounding flora and fauna.
