Plants provide almost every calorie of food we eat. Grains like rice, wheat and corn make civilisation possible. For millennia, farmers have bred grains, fruit and vegetable varieties to get larger harvests and plants better able to tolerate different climates.
But climate change is going to bring enormous disruption to the plants we rely on. A hotter world. Drier in some places. Wetter in others. Intensified droughts. More fire. Sudden torrential rain.
