Alice Friedemann: Why we might not go extinct

images-3See the last post for “energy skeptic”‘Alice Friedemann’s analysis of the net peak energy curve. Here is a follow-up: her interesting perspective on what the draining of nonrenewable energy resources from our greedy little hands will do to this civilization. Like taking candy away from children, maybe we can save their teeth?

Once again, folks, permaculture is the solution, as Cuba found when the oil spigots shut off in the early ’90s. Now most of Havana’s food is grown inside the city.

Why we might not go extinct

The case against extinction

Energy is the master resource that unlocks all the others. Don’t have fresh water? No problem, just use oil to drill down 1,000 feet and bring it up. Can’t find any fish nearby? No problem, build a mega-factory boat and sail it to the ends of the earth where the remaining fish are. And so on. It’s allowing us to mine topsoil and grow crops for a few generations before the topsoil washes and blows off, or becomes too saline to grow crops anymore.

Plentiful oil allows us to make microchips, keep supply chains going, deliver food — there is nothing that does NOT depend on oil at some point in its life cycle.

Burning fossil fuels is also the main reason we have climate change. And why 7+ billion people can survive off of this borrowed energy — on our own perhaps 1 billion could exist.

So the end of fossil fuels solves all of the extinction problems. We will stop emitting so much carbon dioxide. We won’t be able to manufacture as many chemicals as we are now that poison land, sea, and air. We won’t be able to feed 7 billion people whose consumption of every mineral, tree, animal, and plant is destroying the world.

I think the end of fossil fuels and all that they do for us has a 95-98% chance of saving us from extinction because:

1. Carbon dioxide and methane will start to go down due to peak oil and coal (Hart, Heinberg, Höök, Nel, Patzek) and natural gas Shale Oil and Gas Will Not Save Us.

2. Gail Tverberg in Oil Limits and Climate Change: “My estimate of CO2 generation by fossil fuels in the 21st century is only about one-quarter of the amount (range midpoint) assumed in the 2007 Intergovernmental Panel on Climate Change (IPCC) Report.”

3. Our ability to do any kind of harm to any resource will diminish drastically once oil and oil equivalent fuels diminish because so many large vehicles and any other equipment with combustion engines won’t operate any more:

  • farm tractors will no longer compress and erode topsoil (or grow enough food to feed 7+ billion people)
  • earth moving machines will no longer harvest coal and other minerals and metals
  • our roads, bridges, airports, and docks will last less than 100 years because we didn’t build anything with cement to last over a century (unlike Roman cement, which is still going strong). We won’t have the energy to rebuild or maintain most of our infrastructure
  • It will be much harder to chop down (rain)forests with roads crumbling and large trucks gone
  • There won’t be ships that can go to the ends of the earth to harvest the last schools of fish. Marine reserves have often restored fish populations faster than anyone expected.
  • due to lack of fuel, future world wars or world war on the scale of WWI & II will not be possible. Wars will be far more local, more like pre-WWI.
  • Although biodiversity loss will probably increase initially as anyone with a gun goes out hunting, that’s likely to change because the people who live where hunters can get to on foot or bicycle will defend their territory. The same goes for fishing and foraging.

3. The book “The Earth Without Us” gives me great hope that the earth will recover rather rapidly.

4. In 2075 when sea levels start to rise, so many people will have already died off from the decline in fossil fuels that there will be plenty of room for coastal dwellers to move to

5. The loss of our ability to make microchips and breakdown in supply chains will be nearly as important as the loss of oil in rapidly changing civilization back to wood-based energy, and also increase the rate and numbers of people dying.

I don’t want to diminish the suffering and tragedy of between 3 and 7 billion people dying, of climate change wreaking harm for thousands of years, and the loss of much of the amazing scientific understanding we have of the world since so much of it is being preserved digitally instead of on a more permanent physical substance (i.e. imprinted on thin metal sheets, etc).

Even though even a small nuclear war would kill over 1 billion people, and a nuclear EMP even more, the ozone would recover after 5 years, many people around the equator will be fine, others will have stockpiled enough food to get by.

All of the 9 planetary boundaries will diminish as human population declines from lack of fossil fuels. Peak phosphorous will come even sooner without fossil-fuel driven vehicles and equipment to harvest and transport it.

This is too big a topic to list every factor and how it might turn out as you can see from the menu items in Decline and Collapse at Yes, extinction is a possibility if too many of these happen at once over just a few centuries.

But since both human population and energy resources are likely to decline exponentially rather quickly, we won’t be able to do the harm we are now, to the planet or ourselves, and that has a good chance of saving us from extinction.
