'Earth provides the magnificent opportunity to face the ecological crisis through architecture and housing. More than that, it is one of the obvious alternatives for sustainable development.' Jean Dethier finishes this video reminding us what the role of this building material can be in the future. Although I could not agree more, I am also aware of the fact that there is still a lot to be done in order to take this material forward. Even so, and considering that so much has evolved in terms of techniques since the exhibition he put together in the 1980's, I truly believe this will eventually happen.
