What if ending food insecurity meant ditching charity models that haven’t been updated since the 1960s? Dion Dawson, TED Fellow and founder of Dion’s Chicago Dream, shares how he turned a spontaneous idea for giving back to his community into a thriving social enterprise, delivering top-quality produce to thousands of Chicago households every week and reaching a million dollars in revenue in just 18 months. He’s proving that it’s possible to replace the outdated food pantry model with a data-driven system that delivers high-quality food — so your zip code doesn’t decide how long you live.

There's an invisible super-pollutant heating up the planet — but it's surprisingly easy to reduce, if we try. Revealing how methane contributes (way) more in the short term to global warming than carbon dioxide, chemical engineer Daniel Zavala-Araiza highlights the emerging technologies and bold new policies that are part of a worldwide effort to hold oil and gas companies accountable for polluting our skies with this harmful gas. It's an optimistic glimpse into a future where global cooperation and cutting-edge monitoring could rapidly slow climate change. (Recorded at TED Countdown: Overcoming Dilemmas in the Green Transition on October 30, 2024) 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.
