According to this article lost golf balls are becoming something of a problem. That’s because they can take take anything between 100 and 1000 years to decompose and are becoming something of a litter problem. When they do start to break down the balls release a high quantity of metals including zinc. When submerged in water this poisons the surrounding flora and fauna damaging the environment. I wonder if there is such a thing as a biodegradable golf ball.
