I know what you're saying :) Yes big business should indeed be dealing with their mess. OTOH, being pragmatic, given that getting them to take responsibility is so hard to do, and time-consuming, and that we face an emergency right now, I wonder, are there other things we can do anyway. Also much of the CO2 was emitted in the past and is hanging around. Should oil companies be on the hook for what was pumped out in the 60s? Well maybe, but will we get them to pay to fix that, indeed can they afford that? Don't know, but in the meantime can we come up with some clever tech? I'm shocked, that friends, colleagues, family, generally people I know that do seem to care about others, nevertheless seem to think its OK to go on a flight for their holiday, seems they put their fingers in their ears while booking the flight. What are we going to do about this? Any government that tries to legislate to stop leisure flights will get kicked out of office quickly. The best hope for that is things like sleeper trains, electric planes etc.I guess my argument is, people as a whole are behaving utterly irresponsibly about the climate and taking us ever more rapidly towards disaster and point of no return, so I feel as technologists we should try to find ways around this. What else can we do?
