So? Big numbers are meaningless without context. 44k opposed to what? What would it be if there were no humans? What can we do to limit our impact but still live a modern life? Like why do people think these numbers matter to normal people? Just antihumanism or something else?
Search "background extinction rate". Wikipedia:
https://en.wikipedia.org/wiki/Background_extinction_rate
Very 1st reference has this in its description:
"By the most conservative measure - based on the last century's recorded extinctions - the current rate of extinction is 100 times the background rate."
So basically, humanity is 'helping' species to go extinct >100x faster than normal (when considering timescales of millions of years).
That's called an extenction event. For which there have been very few in Earth's history that equal what's currently happening.
In other words: humanity has an impact on biodiversity of similar magnitude as supervolcano eruption or dinosaur-killing meteor strike.

To a lot of people, they don't. Until... entire ecosystems collapse and/or changed weather patterns cause crop failures & famines all over the world.
