Confronting Australia's Biodiversity Crisis

Roughly a third of all global mammal extinctions in the last 500 years are thought to have occurred in Australia. At least 34 species have gone extinct since European colonisation, and over 2,000 species of mammals, birds and invertebrates are now listed as critically endangered or threatened. Without substantial and rapid change, this list is almost certain to grow. Ruth Evans investigates what can and should be done to prevent further casualties and turn things around.
