All natural and technological processes,
Proceed in such a way that the availability
Of the remaining energy decreases.
In all energy exchanges, if no energy
Enters or leaves an isolated system,
The entropy of that system increases.

Energy continuously flows from being
Concentrated to becoming dispersed,
Spread out, wasted and useless.
New energy cannot be created and high grade
Energy is being destroyed.
An economy based on endless growth is
Unsustainable

The fundamental laws of thermodynamics will
Place fixed limits on technological innovation
And human advancement.
In an isolated system; the entropy
Can only increase
A species set on endless growth is
Unsustainable
