Of course there is. Our climate is getting less hospitable, right now, in our lifetime. Storms are stronger, wildfires are more frequent and severe, we're beginning to strain our fresh water aquifers, etc. We are seeing really alarming rates of decline of flying insect biomass and other signs of an ecosystem in distress, and that ecosystem provides us with trillions of dollars of value. There is no human industry without our ecosystem to support us.
Solar, wind, etc. are also getting more and more competitive with fossil fuels, providing a purely monetary incentive.
And if we disregard all long term incentives, who cares about space? Even if we use very optimistic figures we're not going to be exploiting extraterrestrial resources for a few decades. And if we encounter significant setbacks (which I have to imagine we will) that take quite a long time.

I'll believe it when I see it. But if this is true, then wouldn't you say, by your logic, that this is a near term incentive for developing sustainable technologies?
> But there are reasons to be optimistic...
I agree. I don't think we really disagree in principle on any of this. I think we have different values and different levels of skepticism (or perhaps are skeptical of different things) but broadly/directionally agree.

The short-term incentives string together into a long-term plan.

Which has been enough urgency to do what exactly?

Great example of folks pursuing short-term profit incentives making progress towards a long-term goal.

If we try. Yes. If we gut those programmes, no. (For the technology benefits we just have to try.)

I think so too.
I think some people are motivated by stewardship and others by exploration. Focusing one one at the expense of the other is a false economy. And pursuing both doesn’t necessarily mean a long-term trade-off.
