I thought the current conclusion is: we're at the tipping point now that would allow most wildlife to persevere. We need to be changing course now or yesterday to save the majority of even most if any at all. There are efforts, but most habitats are on course for nearly irreversible modifications.
Humanity will survive, at the cost of other wildlife on the planet.
The problem is that you will end up with a massive shortage of man power. Automation may fill in the gaps but at the end of the day you will end up with a labor shortage.
There also is the problem of not having enough people to take care of the elderly. We are slowly moving to a future where the majority of the population is old and grey
When you have 8 bajillion people on the planet, every time a baby is born, the individual value of human life across the species drops slightly, due to the increase of supply.
Just need more access to birth control globally and suddenly we won't have half the problems because we have half the population. With added bonus technology to make up the labor difference. I'm sure Thanos would be proud.
