Beset by plunging biodiversity, pathogens and skyrocketing populations, our global food supply is at risk — but solutions that rely on chemicals and GMOs come with their own problems. Laxmi Parida proposes an organic solution instead: math. TED@IBM was a TED-curated event produced in partnership with IBM.
