5.What to do? Adapt, mitigate or both?
The human population approaches seven billion people, and we are severely depleting the natural resources of our planet. Most people will understand that when human population increases by the population of Germany every year, and when most people want to have a lifestyle like upper middle class in California, the natural resources will not be sufficient. So what should be done? As a general rule, our ecological footprint must be reduced. We currently consume too much of our resources. On the other hand, our economical system depends on growth. How can we eat at least parts of our cake and still keep it? We can either reduce the human population or reduce our levels of consumption and pollution or both.

Possible actions:
  • Global moratorium on coalfired power plants: No new coalfired powerplants built from 2011 without at least 80% cleaning of emissions
  • Triple energy efficiency in the world's fleet of cars and halve annual average length of driving by 2020
  • Coordinate efficient, smart energy use nation- or regionwide by computers, grid, windmills, solar cells, electric cars by 2015
  • Reduce flight fuel use by 80% by 2020
  • Halve energy use in buildings by 2020
  • By 2020 all new buildings in the developed world are "smart and active-houses" .
  • By 2030 there is 90% carbon sequestration at all fossil fuel power plants
  • Dramatically increase tree planting, especially in the tropics
  • Rapid development and expansion of non fossil energy sources and carriers - solar, hydrogen, wind, geothermal, nuclear
  • Reduce long transport of food by 50% by 2020
  • Personal annual carbon quotas by 2020
  • Halve waste production in developed world by 2020
  • Fossil fuel faded out by 2040
  • Work systematically to reduce population growth and reduce ecological footprint
