US miner under further investigation after destroying WA habitat of black cockatoos, quokkas and numbats

US mining company Alcoa is facing further investigation for deliberately breaching environmental laws at its Willowdale mine in Western Australia, destroying habitat for protected species including black cockatoos, quokkas, and numbats. This follows a $55 million settlement in February for similar violations at its Huntly mine, and a previous $40 million penalty to avoid prosecution.
