I'm optimistic that we will survive, pessimistic that social justices will occur.

I think that movie is full of bullshit.

i quit watching after the twit said wood has a low energy density

i had thought, generally speaking anyways, the density values for fuels does not typically include the weight of oxygen required for combustion, so it's all gibberish to me

apathy overwhelms me...

time to upgrade to supersized on my soft drinks for the next week
i really need to start adding more to my carbon footprint

>>4999161
It has a low density, compared to oil, no?

no.
the calculation and result tends to change as technology 'improves'


Richard Feynman and John Wheeler, calculated that there is more than enough energy in a coffee cup to evaporate all the worlds’ oceans....coffee

good enough for me....even if they were joking

>>pay back debt before the banks collapse and can't reclaim it

To be fair, in a soft crash (which would be more probable), debt would be a VERY bad idea, but IIRC in this documentary they were suggesting a hard crash? I don't know.

Tinfoil hat.

Can't say I'm happy with everything, but I was okay with the ending. It pretty much encapsulated the transition town movement.

>>4999346
That's completely plausible.

Just build a complete Dyson sphere and live inside it.

inb4 energy availability encourages exponential growth inside the sphere

O-oh, we're posting youtube links now?

Typical doomer viewpoints.

>Collapse is imminnet, prepare to live a 19th century lifestyle again.

Yes, the near future might not be very pretty, but in all probability it will be more Deus Ex and less Mad Max. Malthus has been proved wrong again and again.

Global boom and bust of the human population, until our population stabilizes. Nothing new here, it has been an accepted fact of biology for awhile. Think of a deer population on an island. Only instead of deer it is humans, and instead of an island it is the world.

>>4999488
Just because Malthus didn't predict advances that would allow for more people doesn't mean that there will never be mass die-offs ever in the future ahead. Future is pretty big.

>Charlie Brooker

there is a finite amount of carbon, hydrogen, and oxygen on the earth.
people are made of carbon, hydrogen, and oxygen.
people consume carbon, hydrogen, and oxygen.
therefore there can be a finite number of people on the earth.

the earth is a open system to energy.
the sun can supply a lot of energy.
if people become beings of energy and need to only consume energy it is possible to live for much longer as a species
therefore people should become beings of pure energy

>People consume hydrogen, carbon and oxygen.

Nope. At best they temporary sequester it.

>>5000200
it is not like any of that hydrogen, carbon and oxygen becomes part of a person's body. That would be ridiculous.

I feel optimistic from a technological standpoint.

However, I feel pessimistic from a political and religious standpoint.

>>5000226

this.

>>5000213
Wow. It is almost as if you don't know what "sequester" means.

>>5000240
Wow. It is almost as if you are a good troll.

>>4999130
good doc
