The 4D computer simulation allows a range of dynamic performance software to be carried out. Sustainability is part of a trend to once again consider the whole instead of specifics.
Sustainability emphasises relationships rather than pieces in isolation.
The ecological movement has focused attention during the last century on the degradation of natural systems. This brings to light the connections between natural and human communities and between nature and culture. Sustainability has come to mean that we are one species in a web and that we are dependent on the natural world for our survival. There is a growing awareness and acceptance that population growth, resource consumption, and pollution are combining to weaken the ecology of the planet. There is evidence to suggest that we are altering the energy flows and material and nutrient cycles of the planet significantly enough to endanger and threaten a healthy future for humans and many other life forms.
