The 39-year-old Oscar- nominated star said that he has witnessed environmental damage firsthand, when he dove in the reef 20 years ago, it was paradise as compared to when he went underwater a couple of years back, where all he could see was "bleached coral reefs and massive dead zones", according to a report.
