Hollywood icon Leonardo DiCaprio urged his fans to sign a petition asking Utah’s political leaders to protect and restore the Great Salt Lake. In an Instagram post on Monday, DiCaprio posted a photo of a receding Great Salt Lake shoreline, sharing with his over 61 million followers the dangers a disappearing lake poses. … DiCaprio shared his support for the group of conservation organizations that filed a lawsuit against the State of Utah over alleged “failures” to protect the lake. The lawsuit claims Utah’s diversion of water upstream is preventing necessary water from reaching the lake, depleting water levels.
