Our brains evolved at the time when mankind’s ecological footprint was marginal. Now with humans freely shaping the surface of the Earth the understanding of the global impact of our behaviour is needed. The complexity of ecological interactions is immense and ecologists use most advanced computational tools to uncover and understand their functioning. And while they do, it is enough for us to turn to the very basics of the economy of nature to guide our everyday choices. Barbara Pietrzak, a scientist working at the Faculty of Biology at the University of Warsaw, describes how changing our diet may save the world’s ecosystem and why lowering meat consumption is the single best way to address the challenging ecological concerns.
 Barbara is an Assistant Professor at the Faculty of Biology. She works on the broadly understood animal response to threat, as well as ecology and evolution of their behavior and life history, including longevity. She teaches classes at the Faculty of Biology and Artes Liberales on ecology of individuals and ecosystems, global environmental changes and civilization threats. A member of the Spokesmen of Science and Science for Nature associations. She publishes articles, conducts lectures, participates in radio programs and embraces shorter and bolder forms of science popularization such as scientific stand-ups (finalist of FameLab contest). This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
