Living Sustainably

SustainabilityEcosystems

Our existence, lifestyles, economies depend upon:

 

Solar Capital = Sun


Earth Capital = Planet's air, water, soil, wildlife, minerals, purification, recycling 

 


Are we impairing the earth?

 

Can we live more sustainably?

 

The earth's natural processes developed over billions of years.

 

We need careful use of ecosystem services.

Two Basic Principles:


1. Energy flow =

One way, need constant input from sun (<1% of sun for photosynthesis), powers all life.

 

2. Nutrient Cycling =

Cycles over & over (ie., honc)

Decomposers needed here!

Why are ecosystem services so important?

 

We are all a part of nature

 

Services constitute earth capital

 

Support all life, essential to quality of life and all economies.
