No, they don't. They only cause damage if someone wearing them reaches out to touch the reef. Guess what? if someone who isn't wearing gloves touches the reef, the reef can become damaged. Guess what again, if someone wearing gloves doesn't touch the reef, no damage is done.Bruciebabe:Gloves also lead to reef damage when worn diving.
Wearing gloves causes SOME people to be less careful with their hands because of the protection they enjoy. Generalizing all glove wearers is wrong though.
