Guest Idea: The Hidden Environmental Cost of Lost Golf Balls

Every year, American golfers lose an estimated 300 million golf balls, according to research by the Danish Golf Union — and that figure, dating to 2009, is almost certainly too low. A 2024 CNN investigation using updated participation data estimated the U.S. number could now exceed 1.5 billion annually, with the global total up to 3 billion.
