It is unfortunate and many are probably unaware of it, but some photographers are damaging the natural environment of our oceans.
If you have huge bulky cameras then this can cause damage to coral reefs and other organic sights. Always take care when out in the ocean because what is damaged by one person will most certainly ruin any sights for others and most importantly any nearby marine life. Be careful and make sure we preserve the beauty and not just in a few photographs.
