Lily Cole has said she nearly did not publish her new book as she feared it would attract personal attacks and scrutiny.
The model and activist, pictured, wrote Who Cares Wins: Reasons For Optimism In Our Changing World in an attempt to tackle issues around sustainability and global inequality.
However, the 32-year-old said the book, featuring interviewees such as David Attenborough, nearly didn't make it to print.
Cole said: "There was a time when I was considering not publishing this because I could see I was bringing into my life the possibility of personal attack or scrutiny.
"Right at the end, after all the work, I emailed my agent and publisher, trying to get out of it.
She added: "My lovely agent, who's very wise, said: 'Take a few extra months, think about it and come back to it.'
"I eventually decided that what was stopping me was my own selfish fear about how it could personally impact me."
Devon-born Cole, who was raised in west London and went to Cambridge University, said she comes from a less wealthy background than is assumed.
She said: "The media often think that I come from a different social class to the one I actually come from.
"I come from a very poor background and I feel I have had very diverse experiences."
