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.

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.Recently, 600 couples from the South American nation of Paraguay were married simultaneously in a gym.

They're full of drama. And they rarely turn out exactly how you wanted. Dan Woodman, Professor of Sociology at the University of Melbourne, discusses why weddings still have a role in people's lives.
