OP, I'm with you. And I have (older) DC.
Many of us understand the science of the climate emergency. We are becoming increasingly aware of the impact these changes will have on food production and distribution, transport and logistics, scarcity-driven conflicts over natural resources such as water, salination of freshwater sources and desalination of oceans and its impact on marine life and fishing, the collapse of AMOC, rising sea levels and the movement of displaced populations, the spread of new pathogens and future pandemics, the pressures on medicine and health care, climate initiated natural disasters, the vulnerability of housing and shelter and so on, not to mention the kind of societal breakdown that arises in the face of perceived scarcity. It is immense, so big in fact, that the recent Joint Intelligence Committee assessment titled 'Global biodiversity loss, ecosystem collapse and national security' has, some say, been deliberately 'buried' and kept from public scrutiny -it's that worrying.
I think that, when weighing the impact of the climate emergency on almost every aspect of life as we know it, few actually think "M'kay, all of these things are underpinned by good science: this doesn't look too great for my future offspring, but I am going to dedicate my life to alleviating the suffering likely coming our way, and shoulder the responsibility for putting future DC at the centre of this, and they'll thank me."
Instead, there is a sort of capitulation that happens when we are faced with overwhelming and conclusive evidence that we are knowingly going to put our future DC in more challenging circumstances than those in which we ourselves grew up. This is entirely understandable but it doesn't make it any 'better'. This thread has posters comparing being born into a war zone (localised, time-limited and escapable) to the altogether different scenario of tanking weather systems, and deciding on behalf of their future offspring that it'll somehow 'be worth it'. I am totally baffled by this, and can only conclude that perhaps posters who reason along these lines have not experienced sustained suffering and are, for this reason, OK with placing their DC in this situation. To suffer is awful, to be impacted by scarcity is awful. To know the suffering you're in is not just a temporary blip such a delayed flight or a bout of chickenpox, but the way things are going to be going forward -that's awful.
Yet we procreate. I get it and I hear all the stuff about it being -naturally- a selfish act; as if that makes it OK. But selfish is really all that is left when we peel away all the things we may be doing to mitigate impact in our own lives. How are we able to tell ourselves it is in our gift to make this decision on behalf of hitherto unborn children?
A hard circle to square.
