Trees

For me, trees have always been the most penetrating preachers. I revere them when they live in tribes and families, in forests and groves. And even more I revere them when they stand alone - Herman Hesse
As a member of The Woodland Trust, I regularly signed petitions to preserve ancient woodlands and unique trees. Does this make a difference? The battle is an ongoing one, but worth fighting, if necessary tree by tree.

Visiting Luc Schuiten's Vegetal City exhibition in Brussels back in 2009 served as an eye-opening introduction to the potential that biomimicry might play in helping us design a sustainable future.
Many projects are already underway; some young architects are designing structures made completely out of living trees, while others are imagining how our great cities might return to their more natural state.
A related website tried to organise all biological information by function and asked the question - what we can we learn from this organism (e.g. any inventor, anywhere, at the moment of creation, could ask "how does nature remove salt from water?")
