Chris Thomas investigates the human inheritance on planet Earth. Intriguingly, his argument is that nature will be thriving in an age of extinction. Thomas does not, however, deny that levels of extinction are high in our age and that there is a strong need for conservation. But for Thomas, besides losses and threats of loss, there are also gains and further opportunities for gains. As a result of human behaviour, many new animal and plant species are, and will be coming into existence.
