Concepts of Sustainability
From Sumerian times to today, we have experimented with what is sustainability. It is arguably possible that several of the most significant factors in the rise and fall of civilizations have been a reliable source of food, water and a place to live. As populations have grown, so to has our ingenuity risen to the challenge of feeding and housing us.
Nonetheless, historically, as we have overdone it and depleted the capacity of the land and sea to replenish our food stocks, the food and water have dwindled.
To name a few, this has come in the forms of crashing fish populations, vast dust bowls, and lost habitats for the very plants and animals we rely on to survive.
According to the North West Forest Plan(1) definition of sustainability in ecology, it is an ecosystems ability to maintain a [steady state] in to the future.
This definition is applicable to many different systems including societal and economic systems.
Jonathon Porritt, an English author, has intertwined three systems into a visual model of the relationship of humans to the world. As he sees it, economics is a function of human society and human society exists as a function of the environment(2). For humans to exist sustainably we need to find a balance between these three systems.
The United Nations Brundtland Report of 1989 suggests humanity must, “…meet the needs of the present with out compromising the ability of the future generations to meet their own needs”(3).
So, in terms of us, now, here in this small portion of the planet, Sustainability is all about finding a way to use our resources thoughtfully, spend our money wisely, and take care of our environment judiciously.
