Conspiracy time! Environmental activist and political leader Brenda Hean went missing in 1972 after her plane mysteriously vanished while she was on her way to the nation’s capital to protest the government-sponsored flooding of Lake Pedder. Brenda had been fighting the government and the Hydro-Electric Commission, who’s damming system was to flood the lake, at every turn. She formed the United Tasmania Group, the world’s first Green political party, to try and save the lake. But the government thought she was getting too powerful, and had to silence her, before their million-dollar hydro-electric scheme was quashed for good… maybe. The mystery of what happened to Brenda Hean remains unsolved, but the fight to save both Tasmania and the world from environmental degradation continues.
