Little appetite

The world’s farmers can satisfy growing demand for food by planting more acres, making each planted acre more efficient, or reducing waste. There’s little appetite to plant more acres. That means few people want to plant more acres. If there’s “no appetite” for something, nobody wants it; if there’s “little appetite,” few people want it. You can use this in a general sense (“there is no appetite for…”) or specific to a person or group, (“American drivers have little appetite for electric cars”).
