Human activities are speeding up normal climate fluctuations on the planet, while this is taking away the time to adapt to new living conditions, for the whole biosphere. Climate influences human activities, which influences again the climate. It is a loop that will never stop if humans do not change their way of living. To slow down climate change, mankind has to change the way they think and behave: they need an ecocentric mindset. Humans need to live in symbiosis with ecosystems to let the biosphere grow, instead of depleting it. With the build environment we can influence the users and passers-by. Therefore, ecocentric architecture has a key role in working towards the ecocentric mindset.
