Do you need to go into space to flag up water shortages?
I'm really not sure what to make of this chap going to space in order to highlight water issues back here on planet Earth.
My first thought is that I'm sure there are more effective ways to spend $35m if you want to tackle water shortages and lack of sanitation. And I'm guessing the carbon footprint of his trip is, well, astronomical.
But then again, sopace tourists are still novel enough to get a fair bit of media attention, so why not use the limelight to publicise a worthy cause?
I guess I'd feel more comfortable if rather than promoting the whole trip as some altruistic eco-mission, he said "look, I'm a billionaire and plan to spend a sizeable chunk of my personal fortune on going into space, because it's something I've always dreamed of and am in the fortunate position of being able to realise.
"And while I'm there, I thought I'd take the opportunity to highlight something worthwhile - I hope it helps a bit."
