We have never had to care so far because we were not numerous. Now human activity is similar to geological forces like rain/volcanoes/etc and i think we should plan how we can exist on a stable cycle.
Mindless growth leads to us breaking our environment through our scale. Scale is exponential so after thousands of years we have a small window of 100 years where we grew so high in impact that we may break it all. It's a first for us, and i hope we can see further than the mold in the petri dish and make a concerted plan on how to live in a stable cycle without growing.
I'm advocating for planning a sustainable future. It's the first time in History we have to deal with this. People assume the future is like the past, and other incorrect things. They also live in cities, removed from physical realities. They only understand the collapse of species through some stats in a newspaper they forget the next day, and the energy/resources supply chains are unknown to them until there is a blackout and they lose internet for a few hours.
The future seems bleak in many ways for physical reasons. I don't think pretending we are not reaching planetary limits will help. I think it will make the fall harder. I would rather we concert and plan together what level of quality of life we want, and how we can stabilize our population, so we can cycle generations of human in a sustainable way.
business as usual leads to a pretty bleak future and if we refuse to confront this how will we even begin to adapt to a planet rapidly growing more difficult to inhabit
