Erik Schoppen shows that our brain is not only an energetic cosmos between our ears, but also a generator of our own ‘happy energy’. The brain, with 80 billion neurons one of the most complex structures in the universe, is a perfect example of nature’s power to develop a sustainable solution that rewards you for thinking positive and being socially aware of others on this magnificent planet we live on. This lecture shows you the ‘mental loop’ of feeling better when you live a more sustainable life. The sustainability symbol was created in 2010 by Erik Schoppen, because he saw in his research a strong connection between positive thinking and sustainable living. As a sustainable neuroscience researcher and human-centered designer he developed the vision ‘Happy Energy = Happy Planet = Happy Future’ and designed the new universal symbol for sustainable and positive energy. The symbol, also known as the 'happy energy' sign, represents a new sustainable era, based on a positive pro-social view and a future-proof environmental approach. This is what he calls Generation-Transcending Leadership - working globally together on our sustainable future. In 2011 Erik Schoppen was co-founder of Happy Energy, Movement for a positive and sustainable world. At the moment he is working towards his PhD (social neuroscience) at the University of Groningen. His research is about Trusting Sustainability. "You experience 'happy energy' when you think positive and choose for a sustainable lifestyle." - Erik Schoppen.
