tourism impact on coral reefs

[Olson]

Hello, my name is Gabriela Peon and I would like to know if titanium
dioxide, a very common ingredient in sunscreen lotions harms coral reefs,
and if it does, would somebody know which sunscreen brand or active
ingredient is truly harmless to coral reefs.  I live in Cancun, Mexico and
we have thousands of tourists snorkeling and diving on coral reefs every
single day of the year.

Any other valuable information you may have on sunscreen lotions effects on
coral reefs or marine life will be very very much appreciated.
