We are talking to journalist Oliver Milman about his new book, The Insect Crisis: The Fall of the Tiny Empires that Run the World. Oliver, who is the environment correspondent on The Guardian newspaper, addresses the shocking decline in the number of insects in the world. He outlines the overall importance of insects from the pollination of plants to their vital role in the food chain, and describes how bees, butterflies and countless other insects are simply disappearing due to the loss of their natural habitat, pesticides, and climate change.
