The 'Once Upon a Time' team was founded in 2016 by a group of scientists who want to be listened to. Scientists who want to transfer knowledge as entertainingly and comprehensibly as possible without compromising on accuracy or scientific precision. In 2017, we published a first volume with stories about the threats that the Earth is facing and the amazing secrets it holds for us. The current lust for knowledge and action in environmental matters now provides the perfect backdrop for the launch of our second volume packed full with new fun and factual tales.
