Global push to eat less meat, and Turia Pitt on why being selfish can be a life-changer

A new global diet plan focuses not only on what you put into your body ... but how to produce food to keep the planet healthy. The EAT-Lancet Commission says adopting its diet recommendations could prevent 40,000 early deaths per day across the world...  and cut emissions of methane, a potent greenhouse gas. The diet's key message: eat way less meat and more plants. Briar McKenzie is an accredited dietitian and Senior Research Fellow at The George Institute for Global Health and Professor Ben Lyons is Director at the USQ Centre for Rural Economies.

In 2011, Turia Pitt was caught in a grassfire while competing in the 100km Kimberley ultra marathon in Western Australia. She suffered burns to 65% of her body. She lost seven fingers, had more than 200 medical procedures, and spent two years in recovery. In her new book, Selfish, she turns her focus to different challenges - those as a parent and partner. She explores sacrifice, guilt, and burnout.

Dan Woodman, Professor of Sociology at the University of Melbourne, discusses why weddings still have a role in people's lives.
