JMO   How many peeps enter the water daily and use it as a toilet??  Someone should do a survey, or better yet,  include in video, if they haven't done that already.  Growing up here in Hawaii we loved to visit Hanauma Bay during a special occasion...when it was pristine.  Should close it for at least a year so nature can restore itself, if it is not to late.  Jmo....🏝
