You are right in my opinion. If you read the whole article he mentions climate change MAY reduce coral reefs by 40%, but overfishing and folks grabbing coral products to sell is what has so far caused the much larger problem. That is how I read the article anyway. Of course, that is not how the headline reads.
June, you’re very perceptive. Simply improving sewage treatment in coastal areas of many of the countries with significant reef areas would do a LOT of good. And fairly immediately. And figuring out how to control poaching would help a lot, too.
