About this episode

The battle ground is changing such that different conditions could favour either the plants or the herbivores. When the balance is broken we could have an ‘outbreak’, which is a situation where one side of the war gets an unfair advantage and grows unchecked. Will climate change compromise the abilities of plants, including our crops, to defend themselves?
