''We've become quite detached from the natural world,'' Leggo said.
The 35-year-old is one of more than a dozen speakers scheduled to present their big ideas at the ACT's annual TEDxCanberra conference on September 8.
He will talk about how his experiences camping in isolated bushland have taught him about life's necessities.
TEDxCanberra will be the fourth event of its kind in the ACT. This year 600 people aged between 10 and 80 are expected to attend.
TED stands for Technology, Entertainment and Design, an organisation which grants licences to hold conferences to discuss ideas worth spreading.
One of the Canberra event's organisers, Stephen Collins, said 60 seats had been reserved for school students. Teachers who bought tickets for themselves would be given two free tickets if they brought their students along.
Speakers include Nobel laureate Brian Schmidt from the ANU, Canberra carer Sally Richards and Canberra dance company Bliss.
Musician Helen Perris, economist Andy Stoeckel, memory athlete Daniel Kilov, youth advocate Samah Hadid, youth representative Hannah Coleman, abortion rights activist Leslie Cannold and shark observer Vic Peddemors also will speak.
Tickets cost $85 and go on sale July 27. TEDxCanberra newsletter subscribers can buy tickets two days earlier.
