BERLIN, May 21 (IPS) - New scientific evidence confirms that human action,  such as carbon emissions causing global  warming, and  industrial-scale search for food, is decimating biodiversity -  and, in some  cases, is driving threatened species to evolve and  adapt at unexpected speed to new living  conditions.
