Sustainable Systems

Sustainable systems: 

Can conserve resources. 

Can produce no waste. 

Can produce no unaccountable costs. 

Can produce no unaccountable effects. 

Can be beneficial parts of the cosmos. 

Can contribute to equitable resource apportionment. 

Can facilitate and nurture the evolution of humans. 

Can be harmless. 

But, humans make unsustainable systems. 

We can do better.
