In his new book, Inheritors of the Earth, ecologist and environmentalist professor Chris Thomas, overturns the accepted story of declining biodiversity on Earth, revealing how nature is fighting back...His book challenges us to "look positively at the impact of humans on the natural world”. The professor argues many animals and plants actually benefit from our presence, raising biological diversity in most parts of the world and increasing the rate at which new species are formed, perhaps to the highest level in Earth's history. A statement from the university about the book said: "He argues that the fauna and flora of Britain are much richer today than 10,000 years ago as a result of farming, towns, gardening, climate change and the deliberate introduction of exotic species. "When the climate warms, there are more of these heat-loving species available to spread northwards than there are cold-loving species (e.g. those restricted to Scottish mountains) available to die out.
