Humans are wiping out about 1% of all other species every year, and ONE OF THE 'GREAT EXTINCTION EPISODES IN THE EARTH'S HISTORY IS UNDERWAY. Pollution, farming and urban expansion, over-fishing and hunting are blamed. Between a quarter and a third of the world's wildlife has been lost since 1970. Populations of land-based species fell by 25%, marine by 28% and freshwater by 29%. Over the next 30 years, climate change is also expected to become a significant threat to species. "Reduced biodiversity means millions of people face a future where food supplies are more vulnerable to pests and disease and where water is in irregular or short supply. No-one can escape the impact of biodiversity loss because reduced global diversity translates quite clearly into fewer new medicines, greater vulnerability to natural disasters and greater effects from global warming."
