Scared about the world (non US fencesitter)

I'm from the UK and 32. Ideally I need to decide now, I want a few years in case we have trouble conceiving, but honestly I just don't want to leave it any longer.

Everything has been getting me down with the world. Climate change, politics, plastics, consumerism and waste, pandemics etc, but at the end of the day I've always wanted a family of my own. I would love a child to care for and love, to give them new experiences and to have someone with me throughout the rest of my life (this is selfish and an assumption that they'll stay with me but I think it's a valid reason).

My partner is usually more optimistic than I am, but this time when I asked if we should start trying now he said no. He didn't actually think Trump would be elected, and then he didn't think Trump would back out of the Paris agreement and make climate change worse.

Now there is the threat of a war with Greenland, and if that happens Nato will be dragged into it and we will be involved in the next world war.

The world feels so bleak, and I feel like whatever happens in the US bleeds into everywhere else.

I completely get how much worse it is in the US, I'm not trying to take anything away from that, but do any other non US fencesitters feel the same way?

I will feel regret if we don't try and the world carries on and is fine, but at the same time I feel like I can't bring a child into this world if the climate is getting worse and there is a serious threat of a world war.

Edit: I'm not planning on baby trapping my partner as one person implied. We were both ready to start trying before Trump so we are both very disheartened on what the future holds.
