Eco-consciousness

Recycling, remodeling, using the old to make a new vision. Interesting architectural concept, from LAVA an architectural firm in Australia, to make use of old buildings and introduce new concepts: energy saving, energy generating, sustainability, supply of natural air flow - in two words: Eco-conscious!
In Kuwait, there is a frivolous sense of endless oil wells, hence total disregards to what the planet needs.
We see old buildings just torn down as if made of carton and new ones built with little consciousness. Could it be the heritage of nomadic bedouin culture: put your tent where your camel can graze, remove your tent as soon as the well is dry, move on to another spot?
But Nomads have a deep sense of resources and earthly respect. They keep their carbon footprint as light as possible. What was lost along the way of development?
