TedX Sydney is back for yet another year, and this time it's bringing you ten speakers at the forefront of thinking in the areas of energy, economic, politics, science and creativity. Each will give you their take on the event's theme, Three Horizons, looking at three aspects of the problem they present – triage (what's happening now), transition (how we're changing) and transformation (what the future might look like). On the program are human rights lawyer and Grata Fund founding Executive Director Isabelle Reinecke, who'll be discussing how law can challenge gridlocks in human rights, climate change and democratic freedoms, as well as climate philanthropist Simon Holmes à Court, who'll dive into how political independents can transform Australian politics. Look out, too, for rewilding adventurer Gina Chick, waxing lyrical on how connecting to nature and each other can improve our future; author and broadcaster Sarah Wilson on "what a former climate activist does in the face of collapse"; and Saibai Seisia Elder Aunty McRose Elu discussing how we can bring Indigenous knowledge lore into our legal system. Other speakers include Bega Group chair Barry Irvin; global ecology professor Corey Bradshaw; singer-songwriter Ruby Rodgers; insect ecologist Tanya Patty; climate finance advocate Tim Buckley; poet and performer Jessica Chapnik Kahn and singer-songwriter Luke O'Shea. Registration is open now.
