We have no financial interest in this area. We have constructed the website because we care about what is happening to our world, and are concerned about the future of children and future generations.

Thanks are due to Margaret, Helen, Debbie, Peter, Carol, Geraldine, Clive, Andrew, Patrick, Ann, Gen and John for feedback on earlier versions of this calculator.
