2040 (2019), directed by Damon Gameau

Fearing for the future of the world his four-year-old daughter will inherit, Gameau set out to investigate solutions to our current environmental problems that are based on existing technology. He travels to Bangladesh, Sweden and North America, as well as Australia, to interview children about the kind of future they want and to examine projects that could make this possible. With clever use of visual effects, Gameau imagines what the world could become by 2040 if innovative programs were widely adopted in the areas of energy, transport and agriculture. He also touches on the obstacles to achieving such a future. The tone is positive and optimistic, demonstrating the many economic, social and environmental benefits of taking action. The clearest, simplest explanation of global warming is alone enough to make this film mandatory viewing for all politicians, but particularly those in denial of climate change. It offers hope amid all the dire prognostications for the world.
