What value Planet Earth?

Here's a "value" game I play in my sales training course. A terrorist kidnaps your nearest and dearest and sends a ransom demand for $25 for their safe return. Do you pay? I doubt it. It just doesn't sound like a serious threat. The kidnapper must be a practical joker. We all know that human a life is worth more than $25.

Now, if the demand was, "$250,000 by the end of the week or they die!", you'd do anything and everything to get the money to save them; sell your house, body, mother, car...

I've just seen the shocking film "An Inconvenient Truth". According to Al Gore, we are holding our only home to ransome and very soon we will kill Planet Earth. Naturally, with this type of threat, I thought "I'll pay whatever is needed to save the planet", I'll suffer shortages, difficulties, hardships, undergo massive behaviour changes ... whatever it takes to get my only home back.....

...so I visited the official website to find out what price we'll have to for its safe return. Er.......it seems that the only 'price' we have to pay is to turn our heating down and encourage others to be kind to the environment. So that's it? It doesn't make sense. Either the price has to be much higher ($250000 x 6bn?) or the threat is grossly overstated.

If I am to believe that Planet Earth is in mortal danger, tell me that it's worth more than $25 to save.
