Modern life is waging a war against ecosystems around us and inside us. Keeping our own microbes healthy is another reason to demand action to preserve the natural worldHuman bodies are like cities, teeming with microcitizens - vast communities of viruses, fungi and bacteria that live all over our skin and inside us.
