Agriculture is the foundation of human civilization, the economic activity that makes every other endeavor possible. But historically, says International Fertilizer Association Director General Alzbeta Klein, the subject hasn't received attention in climate talks.

"It took us 23 climate conferences to start thinking about agriculture," she said during a GZERO Live event organized by the Sustainability Leaders Council, a partnership between Eurasia Group, GZERO Media, and Suntory. "The problem is that we don't know how to feed ourselves without a huge impact on the environment."
