Yeah, early humans were only capable of extincting megafauna. Today, we're doing dozens of species per day! We'd be much more impressive as a species if we didn't limit the use of DDT, CFCs, etc
Modern humans are more impressive than our ancestors, according to you. Is that good, or are we a tsunami?
Exactly, no one knows the answer....
We can't agree as a civilization when this planet started, but everyone knows when it's going to end.... irony is thick around these parts...
"One thing I know, I know nothing."
The world will keep turning, regardless of fitness for human life.
