Very well said. More sunscreen enters the water from swimmers and snorkelers than with divers. It's those first time snorkelers from vacationers and cruise ships that do a lot of damages to the reefs and ecosystems. .
I will be honest - If I'm not diving, I use a lot of sunscreen and I reapply liberally... don't want a recurrence of melanoma.. BUT, I shower it off before swimming in the ocean - which is why we like Orient - most of the places have a shower
Diving is addictive - I haven't been since November of 2018 and am going through withdrawls - unlikely to make it to the Caribbean before next winter, so the gulf coast is gonna have to do this coming summer... going to a meeting in San Diego in the fall, but I can't do 50 degree bottom temps anymore - just too old... I live no where near an ocean - and am not fond of lake diving for the same reason.
