Il potere invisibile dei microrganismi

Any aspect of life on Earth is affected by the activities of organisms that aren’t visible to the naked eye: bacteria, viruses, fungi. Microorganisms are essential to the functioning of terrestrial and oceanic ecosystems and guarantee the indispensable conditions for the other components of planetary biodiversity, such as plants and animals. At the same time, they are the cause of endemic diseases and terrible epidemics, from smallpox to the flu known as “Spanish” – which killed tens of millions of people around the world just a century ago – up to the current Covid pandemic.
