A global and personal perspective

Social Equity

The quest for sustainability

Vitality Integrity


Living more environmentally sustainably means thinking about l.jpg
Living More Environmentally Sustainably means thinking about;

  • Society (population and personal impact)

  • Economics (what is the bottom line?)

  • Ecology (the good and the bad stuff)


Key issues l.jpg
Key Issues about;

  • Resources (not enough good stuff)

  • Pollution (too much bad stuff)

Our “stuff” is moving from a source to a sink too fast!


We are using up the resources upon which we depend l.jpg
We are using up the resources upon which we depend. about;

The “source” of

resources is limited.




Global water shortage l.jpg
Global Water Shortage about;

Today, 1.4 billion people do not have safe water.


Who is using all the water l.jpg
Who is using all the water? about;

Agriculture, through crop irrigation consumes 80 to 85% of the fresh water resources of the United States.



Soil is running away l.jpg
Soil is running away! about;

Half of the cropland in the US is eroding at rates faster than they are being replaced. About 75% of US

topsoil has already

been lost.


And the big one l.jpg
And the big one! about;

Humankind expends in one year an amount of fossil fuel that it took nature roughly a million years to produce.




After we use it we throw it away l.jpg
After we use it, we throw it “away”. about;

The “sink” is also

limited.



Slide17 l.jpg

  • The majority of solid waste is sent to landfills about;

  • We dispose of wastes by dumping them on land or in the oceans, placing them in landfills, or burning them via incinerators.

  • Americans produce about 1500 pounds of “garbage” each per year.


Slide18 l.jpg

Waste Streams about;

  • Major components of municipal solid waste by weight:

    • 25% - paper and paperboard

    • 19% - food wastes

    • 13% - yard wastes

    • 12% - plastics

    • At least half of the municipal solid waste could be recycled or composted.


Chemicals are everywhere l.jpg
Chemicals are everywhere about;

Since WWII we have produced about 70,000 new chemicals.

There is no place that is clean on earth

About 80% of adults and 90% of children have pesticide residues in their bodies.


Slide20 l.jpg

Urban Air Pollution about;

Denver study – homes near busy streets – 6X cancer rate in kids



Slide22 l.jpg

World Carbon Emissions, 1950-2000 about;

From Fossil Fuel Burning

Million

Tons

Carbon dioxide release by Americans is 2X in Japan or the UK



Environmental and resource use problems l.jpg
Environmental and Resource Use Problems warming!

  • Rapid population growth

  • Unsustainable resource use

  • Poverty

  • Not including the environmental costs of economic goods and services in their market prices

  • Trying to manage and simplify nature with too little knowledge about how it works

  • What are the

    Root Causes?

Population is out of control l.jpg
Population is out of control! warming!

  • Yesterday at 1:15pm there were 6,402,138,088 people on the planet and we were adding about 3 every second! (Remember 6.4 billion).

  • It took 4 million years to reach a population of 1 billion (1804).

  • It took 123 years to add the second billion.

  • We will add the next billion in 12 years.


Two problems l.jpg
Two problems…. warming!

  • Too many people (global)

  • Impact per person (developed countries)


Slide28 l.jpg

Ecological Footprint warming!: A measure of the “load” imposed by a given population on nature, or the land necessary to sustain resource consumption and waste discharge.

Our Ecological Footprint, by M. Wackernagel and W. Rees
