Risk of snakebites increasing as reptiles adapt to changing world, says study

Research led by WHO predicts hotter climate will lead to more contact between humans and venomous snakes The risk of snakebites is increasing across the world as reptiles shift their habitats to cope with rising temperatures and growing human pressures, a study of venomous snakes has found. Spitting cobras in Africa, vipers in Europe and South America, cottonmouth moccasins in North America and kraits in Asia are coming into greater contact with people as a result of climate disruption and landscape change, according to the research, which was led by the World Health Organization. This trend is forecast to become more pronounced in the coming decades as snakes – like many other species – adjust their range to escape hotter conditions. Most species will suffer a decline of habitat, but a significant number of the deadliest snakes are likely to spread more widely, taking them into areas where they have not been seen before and potentially affecting billions of people. “The overlap between humans and venomous snakes will be greater,” said one of the authors, David Williams of the WHO and the University of Melbourne. “You could consider this a risk of walking out of the back door, stum
