Yeah we are beyond the point of no return. There isn't much we can do but prepare for the inevitable collapse of human industrial civilization. Industrial civilization WILL collapse when oil becomes too expensive to extract and use. It isn't that far away according to this Youtube video...
https://www.youtube.com/watch?v=8j4Tyy5nsQ8The video is called ""Peak Oil strikes 2020: Oil price spike causes Worldwide Depression and Food shortages """
As the title suggests, we only have another 5 to 6 years left before shit hits the fan. We are SCREWED when the price of oil becomes too expensive for people to afford. Once oil becomes too expensive for people to afford, the economy will collapse because everything we do in our economy (industry, food production, energy production etc) is dependent on oil.
Once the price of oil becomes too expensive for people to afford, society will totally fall apart...food production will effectively grind to halt. No more food production = massive famine on the global scale. And when massive famine starts, society will collapse into total anarchy. Millions upon billions of people will starve to death or die from war, disease, famine, starvation and etc.
What's scary is that this might happen by 2020 which is only five to six years away! I don't know what to do because I am simply not prepared for this!
In short, we are beyond the point of no return. The whole biosphere is fucked beyond belief due to human overexploitation. There are over 7 billion humans on this planet. Once oil becomes too expensive to afford, food production will be gone. And when that happens, the world's population will be reduced by several billion people because there is just NO WAY we can feed 7 billion people without the use of petrochemicals.
When oil becomes too expensive for people to afford is basically the same as oil being totally gone. It doesn't matter how much oil is left in the ground if it is too expensive for people to use it. And when that happens, food production will be GONE. And when that happens, our population will be reduced down to under 2 billion people. So at least 5 billion people will die in the next couple of decades, starting from 2020.
So yes, we are beyond the point of no return. Peak oil will fuck us over within the next decade or two.
History repeats itself. Just everytime with different characters and players.
