Australia has many serious environmental issues. It has the worst record of animal and plant extinctions over the past two centuries. Introduced animals like cats, foxes and cane toads threaten the wildlife. Introduced weeds like mimosa pigra are invading huge areas of our bush. So much land has been cleared that forests and woodlands (14% of Australia)  have been damaged and salt has damaged up to 10% of the farming land. Overgrazing of land and looking after the water supplies are important issues.
