The planet is home to a complex viable web of life, and my species, Homo sapiens, is embedded in, and part, of the Earth's life-support system (ELSS). Human activities over recent centuries have greatly increased the flows of materials and energy from the ELSS to human communities and back into the ELSS. New flows have been created and fundamentally change the planetary physiology. Modern global change is now threatening the planetary health of the ELSS. As a result, we have degraded the ELSS.

The available evidence shows that there is a massive degradation of the ELSS in progress from local to global scales and it is expected that this degradation will accelerated under continuing modern global change. This degradation is caused by a global human population expanding in numbers, economic activities and land use. The welfare of all life on earth, including humans, depends on a healthy ELSS. Safeguarding the viability of Earth should be, and for a thriving humanity must be, at the center of all our activities.

The degradation of the ELSS has created a new class of risks, the Anthropocene Risks, and most of these risks are global catastrophic risks (GCRs).

My life in Atmospheric CO2

  • 312 ppm: Birth
  • 320 ppm: Started as Carpenter
  • 331 ppm: Started at university
  • 338 ppm: Diploma
  • 350 ppm: PhD
  • 373 ppm: Married
  • 395 ppm: Started current job
  • 415 ppm: Today (May 2019)

My “age” in CO2 increase: 102 PPM.
Increase over the last 20,000 before industrialization: 120 PPM.
The increase in my life-time was 300 times faster than on average during the pre-industrial 20,000 years.

Enjoying Nature


Jem Bendell in his excellent essay “The Collapse Of Ideology And The End Of Escape” discusses the ideology of e.s.c.a.p.e that is in all of us, deeply engrained in our (western) society. I think, we need to replace this ideology by an ideology of r.e.s.c.u.e.

  • Responsibility: instead of being entitled to have more than we need, we are responsible for the consequences of our actions. Enbedded in the earth's life-support system (ELSS), and changing it with each of our actions, the consequences are many, and as the most successful and powerful species that we have become, we need to exercise self-limitation in our action and not do all we can but rather make a choice to do what is needed and what safeguards the ELSS. Living our responsibilities can bring us to a better future.
  • Equality: The ELSS is maintains, and is, a complex web of life, and in it we all are equally important and we all have equal rights. We are not an exceptional species, just a bit more evolved than some others. Within humanity, we also are all equal, no matter what hair color, eye color, skin color, gender, or cultural background. Seeing the beauty in the diversity of human beings and enjoying the equality of all of us will bring us to a richer and peaceful future.
  • Stewardship: Being exceptional in the sense of having capabilties no other species on Earth has comes with responsibility. Being able to alter the ELSS fundamentally puts us inhernetly in the role of the steward. We can do a poor job as stewards, but we cannot reject this role: we are the stewards of the planet. We better accept this and live up to it, to ensure the welfare of all of us.
  • Community: The individual is little without a community around. Humans depend on the community: I am because of you. Embedded in a community that is embedded in the ELSS, autonomy is an illusion. Our own indivudual welfare depends on the community around us.
  • Unity: There is only one life-support system and we are an unseparable part of this. Consciousness connects us with the web of life around us and enjoying the unity with the web of life provides for a rewarding future.
  • Education: Education is the door to a better future. Helping our young people to learn about life, to understand the ELSS and the web of life, to reflect on the meaning of life, to see the beauty of life provides a foundation for a better tomorrow. Without education, there is no better tomorrow.

The Gesturing Towards Decolonial Futures collective in a recent article also proposed an alternative to E.S.C.A.P.E.:

“In response to ESCAPE, we have created a provisional list of dispositions that might orient us away from harms reproduced through ESCAPE, and toward deepened responsibility for our shared existence on a finite planet, across species and across generations. We called it “COMPOST”:

  • Capacity for holding space: for painful and difficult things without feeling irritated, overwhelmed, immobilized or wanting to be coddled or rescued.
  • Owning up to one’s complicity and implication in harm: the harms of violence and unsustainability required to create and maintain “the world as we know it” with the pleasures, certainties and securities that we enjoy.
  • Maturity: to face and work on individual and collective “shit”, rather than denying or dumping it onto others, or spreading it around.
  • Pause of narcissistic, hedonistic and “fixing” compulsions: in order to identify, interrupt and dis-invest from harmful desires, entitlements, projections, fantasies and idealizations.
  • Othering our self-images and self-narratives: in order to encounter the “self beyond the self”, including the beautiful, the ugly, the broken and the fucked up in everything/everyone.
  • Stamina and sobriety to show up differently: to do what is needed rather than what is pleasurable, easy, comfortable, consumable and/or convenient.
  • Turning towards unlimited responsibility: with humility, compassion, serenity, openness, solidarity, mutuality and without investments in purity, protagonism, progress and popularity.”
