The former New South Wales premier Bob Carr has warned the environment movement is “In danger of fading” in the face of massive challenges protecting habitats from population pressures and climate change.

“I think there’s a danger in recent years of the environment movement fading,” Carr said.

Carr said he believed the best results for the environment were achieved when dedicated voluntary conservationists worked with “Sympathetic Labor governments”.

Carr said he was very confident the premier, Chris Minns, and the environment minister, Penny Sharpe, would work together with the environment movement and farmers on the issue.

A review of the state’s Biodiversity Conservation Act, led by Dr Ken Henry, found the laws were failing to protect the environment and that clearing of vegetation and intensifying land use had led to the destruction of habitat across the state.
