The spiral down of humanity to extinction..

I am a 60s American male. A so-called "Baby Boomer"
I will expire in 2030 or 2035. (if I'm lucky..)
My children are in their 30s.
The will expire in the 2070s.
Their children will expire in 2100 (if they are lucky...)

What kind of world will be left to humanity in the year 2100?

I fear my grandchildren, who I will never know, will suffer the consequences of the shit we started now.....
The shit we couldn't bother to fix because of greed and stupidity....

I fail to see how we survive a a species.

RIP 2100
