"What we need is not one by one solution. We need to change systems. There's a billion people earning our food. We waste one third food. We use too much water. Pollute every water source there is by a fertilizer. You can't change that by changing one thing. That is what system changes. That is what we need for exponential change and the speed and the scale we require. We don't have time to solve one thing at a time. We need to change agriculture, to food systems, to change cities, change energy systems. That's what we're going to see benefit people, for nature, and of course for climate."
