Plants and Animals Aren't These Inert, Helpless Things

Researchers recorded the sound of cabbage-white caterpillars munching on a cress plant. When played back to some other plants, they responded in exactly the same way. They immediately flooded their leaves with chemical defences to deter predators. We can never know what it is like to be a plant, but we can understand that we share the world with them. It's myopic of us not to take their experiences into account.
