Not “Human Detritus” no :

(…) billion years for the first living (…) to grow (…) into the 1.1 trillion tons of biomass (…)
But all of that is outweighed by (…) concrete and other material that humans have produced (…)

Most matter in concrete is sand and gravel and is not different just by the fact it’s encapsulated in cement paste.
We humans do not “produce” rock. We do break it into gravel and this doesn’t change its nature. By weight, most of the stuff we have “produced” is gravel.

Let’s be responsible with the real garbage and dangerous stuff we “produce” without being alarmist.

Oops, editted.

Edit :
1st axis : 360⁰
2nd axis : 180⁰

Miraculous time for all those innocents tortured in Assad’s prisons and liberated since this toppeling. “A blessing from God (Allah)” they will say.
