Everything that humans do and use entails irreversibly using what is available from the ecosystem. We use up exhaustible natural resources. We produce wastes that harm the environment. We devastate bio and geo diversity. This relationship should be formalized as the Dependence Law to improve awareness of what we are doing to our life support system.

"Humans employ a huge range of transient operations they have installed that invariably involve using and abusing natural resources. Each of these operations provides something deemed of value to society during its lifetime. Each of these operations incurs an irrevocable, un-repayable ecological cost. We are irreversibly drawing down on the irreplaceable natural bounty."
