Dr. Andrew Wallace PhD

Gaylord Nelson in 1970 United States Senator for Wisconsin

"The story goes that Earth Day was conceived by Senator Gaylord Nelson after a trip he took to Santa Barbara right after that horrific oil spill off our coast in 1969. He was so outraged by what he saw that he went back to Washington and passed a bill designating April 22 as a national day to celebrate the earth.“

Santa Barbara Community Environmental Council.

What’s the problem? Why? A sustainable society

Global Warming Climate change

Peak Oil Ecological foot print

How do we know? Ice core records Pollen Insects Glaciers

What will happen in the future? Glacier retreats Ice shelf melting Sea level rising More severe weather storms Droughts

Why does it matter? Plastics Fuel Transport Pesticides Food Medication

Civilisation as we know it!

No know single replacement Wind Nuclear Water Solar Bio fuels

How much land and water do we need to support ourselves?

How many people? What sort of life style do we have?

Energy Consumption in kilograms of oil equivalent (kgoe) per person per year per country (2001 data).

CO2 per capita per country

Bolivia Deforestation

Why do we have the problems we have? Why do we have global warming? Why do we have a problem with the oil? Why do we have a problem with our eco-

footprint?

CO2 and other green houses gasses Need for land Need to keep our economy going

Government People Groups and organisations Rules and regulations International connections

All these things, groups, people, organisations all interact

We have no one centralised control mechanism

What we get comes as a by-product of the way things interact

That includes global warming, peak oil and our eco-foot print!

What characteristics would a sustainable society have?

Population? Production? Agriculture?

More and more people means more and more people to feed

More and more goods to produce More and more roads to make

A sustainable society would need to maintain a constant population level

Balance its production demand Reduce demand Reuse Recycle Localise
