Sir David Attenborough says we in serious trouble if we dont change our ways.

Hans Rosling: Religions and babies. We have reached peak child. Hans Rosling had a question: Do some religions have a higher birth rate than others -- and how does this affect global population growth? Speaking at the TEDxSummit in Doha, Qatar, he graphs data over time and across religions.


Mankind's yearly total energy consumption currently equals one hour of sun's energy hitting Earth. As our energy consumption doubles about every 30 years it means that in the year 2450 we need to harvest 100% of sun's energy. After that we need space based solar power.

Let's assume hard manual labor worker consumes 6000 kcal (food calories) of food daily. That's 25,2 MJ of energy, which equals about 0,7 liters (0,185 US gallons) of crude oil or almost the same amount in gasoline or diesel.

That was good

Indeed, just watching another talk of his, he presents data very well.

Gotta love the internet. For every thing you could say, regardless of topic there's an armchair expert somewhere who has prove you wrong somehow, someway. ( I can't claim excemption here on the subject of ww2 submarines) So please excuse me while i wait for the peer reviewed articles from the scientific community that I'm sure will follow.

I presume the overall point of the hokey math was to prove me wrong in my that fossil fuels are not the cause of the rise, and sustainment of our modern day civilization. To that idea, i laugh. Regardless of how much energy is in a spoonful of gasoline, it doesn't change my overall point, and it doesn't change the reality of our dependencies upon fossil fuels.

First off, im not an armchair expert nor is that math "hokey". Energy analysis is one of the things that they like us to understanding in the NE department here at UT. Second, I never meant to confirm nor deny your argument I was merely testing out someone's claim about the amount of energy in a tablespoon of gas. In fact I agree that fossil fuels are the cause of our rise to modern society however, I do believe that we need to move towards a broader energy portfolio.

Now this is what my ex wife always said to me

Does this mean the planet is going to file for divorce?

Apparently he didn't take into account of the Mormons. As religion, it has a direct impact on the number of births of the people within that religion. Because Mormons have this thing about "multiply and replenish the earth". Personally i don't think the earth needs any more replenishment.

This does become a lot more meaningful if you add "with people of our group/faith/culture/etc"

But that includes the baptising of people who have been dead for decades so they have already multiplied their flock and replenished the earth in the form of compost.

is that in scripture? I'm not one to quote scripture, but apparently number 28 listed here. ( http://www.lds.org/scriptures/ot/gen/1.28?lang=eng ) is where they get it from, or so is my guess.

Google image search, "mormon family" as your keywords. They're all huge in size. On a side note, my father in law, one of the most devote mormon's you'd ever meet, has 98 grandchildren.
