It all started with a big bang. Wait, we don't have to go back that far. The earth was formed 4.5 billion years ago. No, still too far. Try this. It's the middle ages. People in Britain run out of firewood and start burning coal. But they use up the coal on the ground. Miners dig deep. Coal mines fill with water. Samuel Newcomen invents a coal burning steam engine to pump out water so miners can keep digging. James Watt makes it practical for other uses. Now we have ingredients for the industrial revolution: fossil fuels and a way to put them to work. All hell breaks loose. Coal miners bog down lugging coal. Rails make it easier. Rails and steam engine combined / make a railroad. Michael Faraday makes the first electrical motor. Nicolas Tesla invests alternating current. Soon utility companies start burning coal to generate electricity. Meanwhile, Edwin Drake drills the first rock oil well in Pennsylvania. And Carl Daimler builds an automobile running on petroleum. Coal, tar and oil are turned into industrial chemicals and pharmaceuticals that prolong life, more population growth. The Wright brothers start oil-fuelled aviation. Fritz Haber and Carl Bosch make fertilizer from fossil fuels. Fertilizer and oil-powered tractors expand food production, feeding more people. 


World War I is the first fossil fueled conflict. Then comes / World War II giving us guided missiles and atom bombs. In between is a great depression partly caused by overproduction. Powered assembly lines make products faster than people need them. Advertising executives invent consumerism to soak up overproduction. It’s the 1950s. Advertisers use televisions to hook new generations of consumers. 


In the 70s, there is an oil shock. Everyone’s shocked to realize how dependent they are on oil. With the energy crisis, the environmental movement is born. But oil price fall and everyone forgets energy shortages. There is a showdown between market and planned economies. Market wins. Goodbye evil Soviet empire. Politicians decide the market will solve everything. Personal computers arrive. Globalization takes over when the market notices labor is cheaper in China. Suddenly, everyone has a cell phone, but world oil production stalls out. 


China’s now burning half the world's coals to make export products. But where will China get more coal and oil to fuel more growth? Environmental problems everywhere. Rising CO2 levels lead to record heat waves, floods, draughts. Oceans acidify. Topsoil erodes by 25 billion tons a year from industrial agriculture. Ancient forests disappear. Species go extinct at a thousand times normal rates. Freshwater is scarce or polluted. Oil companies drill in miles of / sea water because the easy oil is gone, but a deep water oil platform explodes and fouls the Gulf of Mexico. 


Manufacturing moves to polluting countries where labor’s cheap while the US becomes a casino. The financial sector is 40% of the economy. But Wall Street is overleveraged. Banks fail. Unemployment soars. Credits evaporates. The economy is on the verge of collapse!

OK present time.

It's amazing how far we have come two hundred years. Just three human life times from beginning of industrialization till now. But where are we head in? We can't keep doubling human populations. We can't keep dumping the carbon atmosphere. We can't keep ruining tops oil. We can't keep growing population and consumption or basing our economy on the pleading fossil fuels. We can't just put more money to solve the dead crisises. It's been exaleratingly right but there are limits.


Now that is not the end of the world. We have to do four things fast.
1, Learn to live without fossil fuels.
2, Adapt to the end of economy growth as we know it.
3, Support seven billion of human's stablized population in a sustainable level
4,and deal with our legacy of environmental destruction.


Ensure we have to live within nature's budget of renewable resources at the rate of natural replenishment. Can we do it? We have no choice.


Alternative energy resources are important but none can fully replace fossil fuels at the time we have. Also we design and build our infrastructure for transporting electricity in farming to sup oil, coal and gas.


Changing to different energy sources will require to redesign our cities, manufacture processes, health care and more. We also have to rethink some of our values. None of our global problems can be tackled in isolation and many cannot be fully solved.


We have to prepare for business as unusual. Our best goal is resilience. The ability to observe shorts and keep going. If we do nothing, we still get to a post-carbon future but it will be bleak.


However, if we plan the transition, we can have a world that supports our best communities of healthy creative people, and Eco-systems with millions of other spices. When we're the other, we will info the right of life time.


Understanding the issues and pitching in is all hands on deck.
