>> You mean chickpeas?
>> [LAUGH] No okay I didn't know you were eating chickpeas, actually it's meat.
>> So what's the relationship between meat and water?
>> So let's think about this.
So, well how much water do you consume?
So you probably take a shower everyday?
>> Mm-hm. >> So that cost about 50 liters.
And you go to the bathroom everyday, for maybe five or six times a day, right?
>> Mm-hm.
>> That's another 40 liters.
And you do other things like you use the tap to brush your teeth and
all these kind of things, that adds up to 120 liters a day, right?
>> Okay, that sounds like a lot.
>> But if you look at how much it cost to produce one piece of beef for your
hamburger for example, that costs 3,000 liters of water for one piece of meat.
>> 3,000? >> Exactly.
>> Wow that's a huge difference with 120.
>> Massive difference.
So we can see that if we would just take showers as long as we want.
Even longer than we are currently doing.
But eat less or even no meat.
We could say much morer water.
>> Okay, so you and
I cannot do that because there's no additional impact to be gained.
Your vegetarian, right?
>> Yeah I'm vegetarian.
>> I'm vegetarian, so what we could do is try to find someone else and
make that person vegetarian.
>> Very good. Let's
ask our producer Sies if he wants to join.
>> Hey, were you guys talking about me?
>> Yeah, join us, join us.
Have a seat, have a seat.
>> I heard you say my name.
>> Yeah.
>> What's up?
>> So you're eating a meat burger, right?
>> Yeah, yeah.
I love meat.
>> So we would challenge you to stop eating meat,
during production of this mooch.
>> [NOISE] >> Okay.
>> Okay, but that seems kind of slow right?
Now we are trying to make Sies a vegetarian, and he might convince two or
three of his friends to become vegetarians.
But then it will take forever before the entire world is actually vegetarian.
>> That's true. >> Do we have better ideas?
>> That's true.
We could think about other things like what are our governments doing
to get people to consume less meat, for example, right?
How do we do that?
So, if we look at the European Union or the Dutch government or
the German government, what they're doing is getting a ton of people to take shorter
showers, to turn off the tap when they, >> So
they didn't get this cost-benefit thinking very well?
>> Exactly, they're not applying it very well in their case.
And actually, the only country that I know that's doing this, trying to do this,
is Sweden.
And they're thinking about having a meat tax.
>> A meat tax, so your burger would be more expensive than our burgers.
>> And then you might eat it less, that's the idea at least, right?
>> Well I'm not moving to Sweden, that's for sure.
>> [LAUGH] >> Cost-benefit
analyses help us systematically capture the costs and
benefits associated with a project.
