I would argue that the problem you are pointing out is cultural rather than biological. Humans are very well capable of living sustainably and respectfully and have done so for extended periods of times in different regions of the world. The endless consumtion of an ending earth seems like something that developed together with (e.g. western, capitalist, ...) culture and ideology.
We need to work on changing our collective mindset rather than attempt our own disappearance.
Second part of argument: I believe we can. Humans are very capable to adapt and change. Not sure about collectives, but if you think you can convice a critical number of people to stop reproducing, I think you can do the same in convincing us to please fix our shit.
I notice and appreciate cool details.
I'm spontaneous and up for things.
I can get really excited.
I will support your questionable life choices if your heart is in them.
I have creative associations.
I'm usually good at following other peoples' thoughts.
I collect useful junk as well as quotes and stuff.
I usually carry a bunch of key items that might come in handy, like a lighter, a pen and a pocketknife.
No people but seriously. What are we gonna do about this?
