There are a number of ways of interpreting this contemporary reference to art.
My own is simple:
"Visual creativity with awareness and sensitivity to the natural world"
An artist has a need to create as living creatures need to breathe, this need not have a detrimental effect on the people and planet now or in the future.
Using carbon indiscriminately to recreate artists visions is possibly irresponsible, and short sighted. This may be argued, but for my own conscience and the welfare of future generations, I try to choose biodegradable materials, and find processes that require little if any energy, other than my labour. This means I no longer fire a kiln, nor invest in bronze casting processes. This results in most of my work being impermanent, or changing with time. I find this concept very pleasing, for have an affinity with 'change!
I also perceive environmental art particularly sculpture, as having a place within nature, enhancing, high lighting its natural forms.
Let Art Be Me Workshops have now become environmentally sensitive and an increased awareness of 'arts' position in the natural world can only be for the good.
