Five weeks before the start of the Olympics in Rio, environmental experts and athletes say water pollution is still a major concern.
Guanabara Bay, the venue for Olympic sailing, is full of trash and debris.
Raw sewage still flows from Rio’s poor neighborhoods right into the water.
Rio’s waters were found to contain viruses up to 1.7 million times more hazardous than a beach in the U.S.
Some Olympic sailors said they’re worried about running into the floating trash while competing in the games.
One Spanish Olympic sailor said she once even saw a dead animal floating in the bay.
Despite the concerns, Brazilian authorities insist the bay will be safe for the sailors.
But it’s hard to ignore that one of the most beautiful places on earth, might not be ready for its close-up.
