**The largest creative response to the climate and ecological emergency the world has yet seen.** 2019 was the year of rebellion. It was the year nurses, poets, nine-year-olds and grandparents came together to say: we know the truth about climate change – **now it is time to act.** But what words describe this crisis? What words can help our children come to terms with the future they will inherit? Earlier this year, Culture Declares Emergency invited people from all around the world to find those words by writing a letter to the earth. The invitation was open to all – to think beyond the human narrative and bear witness to the scale of the crisis. Letters of love, loss, hope and action were written by over 1000 people. Now published as a collection, *Letters to the Earth* brings together the voices of children and the public with authors, scientists and playwrights in the first creative project of its kind. Alongside letters from the public, *Letters to the Earth* received submissions from artist and peace activist **Yoko Ono** , actor **Mark Rylance** , writer and illustrator of The Lost Words **Jackie Morris** , novelist **Anna Hope** , environmental writer **Jay Griffiths** and Green Party MP **Caroline Lucas** . Together they are an invitation to consider how this existential threat affects the way we live our lives and the action we take. Lots of books consider the climate and ecological crisis from a political or scientific perspective, but *Letters to the Earth* is the first book to chronicle *how* humankind is collectively processing planetary crisis.
