At the rate things are going, the Earth in the coming decades could cease to be a “safe operating space” for human beings. That is the conclusion of a new paper published Thursday in the journal Science by 18 researchers trying to gauge the breaking points in the natural world.
The paper contends that we have already crossed four “planetary boundaries.” They include the extinction rate; deforestation; the level of carbon dioxide in the atmosphere; and the flow of nitrogen and phosphorous (used on land as fertilizer) into the ocean.
“What the science has shown is that human activities — economic growth, technology, consumption – are destabilizing the global environment,” said Will Steffen, who holds appointments at the Australian National University and the Stockholm Resilience Center and is the lead author of the paper.
“There’s a lot of emotion involved in this. If you think about it, the American ethic is, ‘The sky’s the limit.’ And here you have people coming on and saying, no it isn’t, the Earth’s the limit,”
The ozone boundary is the best example of world leaders responding swiftly to a looming environmental disaster. After the discovery of an expanding ozone hole caused by man-made chemicals, chlorofluorocarbons, the nations of the world banned CFCs in the 1980s.

Personally I couldn't wait for hoverboards and flying cars ala Back to the Future II, and yet here we are in 2015 and nada...
As for a realistic example - well the WP article references one optimistic precedent:

But yeah, this is a lot bigger/more complicated than that. I think we do have the capacity to implement solutions personally - the industry I work in (renewable energy) is doing this right now, but more people have to get on board, and specifically wake the f*** up.

If it isn't clear yet that our soul purpose on this planet is to destroy it then I really do not know what else can convince people.
Give me ONE realistic scenario that will turn us off our present course of consumption and pollution that we call "growth". It has to end bad.
Remember before the start of the 21st century, we used to imagine the future and how cool it was going to be?
WTF happened?

I figured this would have something to do with the increasing mass of the earth causing it to exit the orbit of the sun's "habitable zone"... anyway... nice avatar...

But also because of this - that's why I firmly believe the solution starts with us and not "them". I would never count on these people to pull us out of this flaming tailspin.

I do not think an intellectual revolution will occur, seems less likely with each passing day.

The carrot and the stick dangled before you. Heres where that is leading…

The solutions are out there, but they require a paradigm shift in public attitude and acceptance.

it almost seems like the oil cartels pay people to spread their drill baby drill propaganda on forums like these.
