From Richard Jones, West Linton, Scottish Borders, UK
What horrifying thoughts from geneticist Chris Mason, with his idea of spreading humans across the galaxy (17 July, p 44). We may be the most intellectual creatures on this planet, but are hardly a role model.
We kill our fellow humans in wars and our self-centred attitudes have eliminated many other species. Positive human traits are countered by the infiltration of greed and crime throughout society. We are already well on the way to creating a planet that is largely unfit for us to live on. Should we really seek to transfer these attitudes more widely?
