Rio Tinto bosses lose bonuses over destroyed Aboriginal caves

Available for over a year

Mining giant Rio Tinto has cut the bonuses of three executives over the destruction of two ancient caves in Australia. But is it enough? We ask James Fitzgerald from the Australasian Centre for Corporate Responsibility. And are mining companies in general improving their record on the environment and the safety for workers? A question for Tom Butler, chief executive of the International Council on Mining and Metals. Also on the show, we look a the impact of the coronavirus pandemic on Bali tourism. And Elizabeth Hotson investigates nudge theory - the idea that a small prompt can alter behaviour. (Photo: an ore handling plant in Pilbara, Western Australia. Credit: Getty Images.)
