Spencer Tunick said Monday that he had repeated a 2011 nude staging at the famously salty sea to show how sinkholes are ravaging the area and called on the Israeli government to take measures to protect it.

For the latest installation, Tunick had 15 naked men and women pose in sinkholes going up to their waists at the same location he had photographed five years ago to show how much the beach had changed.

Some 2,000 sinkholes have been identified on the sea’s western shores, and its shoreline is expected to drop nearly 20 metres by 2020, according to EcoPeace Middle East, a joint environmental group.

“I care deeply about the future of the Dead Sea and hope that my presence and involvement here can propel the Israeli government and local activists to take real measurable action to save the Dead Sea,” said Tunick, according to a press release on Monday.

His new exhibit, which includes the nude art from 2011, is scheduled to open Tuesday in the Israeli city of Tel Aviv. Pictures from Tunick’s latest installation is still to be processed and will not be part of the two-week exhibition, according to Tunick’s spokesman.

Tunick made headlines in July for staging a protest with 100 naked women against US presidential candidate Donald Trump at the Republican National Convention, according to the release.
