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
