Earth will not be complete without us. And we are definitely not complete without earth. Most probably earth would go back to just having bacteria living here.
But I really thank you for writing this. Why not be a very smart and adaptive species and reinvent ourselves on this planet? We can do it. Many of us in the undercurrent are already doing it. And we have all the tools in biomimicry, blue economy, regeneration and economic reform.
It just needs a different mindset...
