Why the hidden world of fungi is essential to life on Earth

Fungi have long supported and enriched life on our planet. They must be protected fiercely. "As you read these words, fungi are changing the way that life happens, as they have done for more than a billion years. They are eating rock, making soil, digesting pollutants, nourishing and killing plants, surviving in space, inducing visions, producing food, making medicines, manipulating animal behaviour, and influencing the composition of the Earth’s atmosphere." Merlin Sheldrake argues that fungi must be protected at all costs.
