be a hunter gatherer... only way to save the Earth?

It is now well established that humanity is facing a resource shortage at relatively short term (here an example article on water shortage).

If we take as a key hypothesis that we do not stand the loss of even one life, an equation for humanity would be:

at every instant t:
1/ R>=N for each individual
2/ Sum of R >= available R
Where R is available resources for each and every individual’s vital needs N.

The progress of humanity as a whole would then be ensuring the equation is correct at any instant.

Or is it? Because resources are also necessary for the rest of life around us.

The equation would become:
at every instant t:
1/ R>=N for each living creature
2/ Sum of R >= available R
AND
3/ ensure remaining resources can sustain the global biosphere.
Where R is available resources for each and every individual’s vital needs N.

From there, humanity can act on several parameters:
- the headcount
- the nature and extent of so-called vital needs
- access to, production and management of resources
- the quality and diversity of the biosphere

There is also another parameter: accepting loss of human life.

The blue tit

There will be virtually nothing left to fish from the seas by the middle of the century if current trends continue, according to a major scientific study.

Well, I probably won’t be there anymore at this time, when the fish will have gone.

The fish, and the whales, and the dolphins, the belugas, the sea lions, etc. The sharks will disappear, as well, as they won’t have anything to eat anymore.

Edit=> I have just seen that postcard wrote an entry on the same subject two days ago.

We cannot save the world but we can do something to save ourselves in the United Kingdom. For this, we need secure indigenous supplies of food and energy. Our only immediately available energy comes from coal and nuclear, our gas and oil will soon be gone and we can not rely on supplies from abroad.

We need urgently to recommission, not decommission, our nuclear power stations. The stories of vast costs and of dangers from nuclear wastes are unreal and no more than fearful imaginings born from Cold War propaganda.

_MI5’s maxim is that society is “four meals away from anarchy”. In other words, the security agency believes that Britain could be quickly reduced to large-scale disorder, including looting and rioting in the event of a catastrophe that stops the supply of food. [...] _

Our future in 2100: no good

Scientific American September 2006 issue: Energy’s future beyond the carbon

_Another summer of record-breaking temperatures brought power failures, heat waves, droughts and tropical storms throughout the U.S., Europe and Asia. Only one place seemed to remain cool: the air-conditioned offices of the editorial board of the Wall Street Journal … _

_The 2006 Automobile Salon in Paris _

The 2006 Automobile Salon in Paris marketing campaign visuals are based on a planet Earth in the form of a car, with part of its water and atmosphere going into space as the “car” speeds up.

This is animated on their web site: http://www.mondial-automobile.com/ .

One day, quite soon, we will wake up and see the destruction and pollution we impose on our planet Earth.

I hope it won’t be too late.
