Air travel opens our eyes to the world, but it also comes at a high cost to the environment. Piloting us into a future of green aviation, innovator Ryah Whalen shares three ways to lower the industry's carbon footprint through smarter designs, eco-friendly fuel and new technology -- so we can continue to explore the planet without hurting it. Countdown is TED's global initiative to accelerate solutions to the climate crisis. The goal: to build a better future by cutting greenhouse gas emissions in half by 2030, in the race to a zero-carbon world.
