Since when did we have so many?
Was there a time when there weren’t any endangered animals?
How many are on the list?
How many less animals do we have now than 4,000 years ago?
>Since when did we have so many?
Basically since people started to notice that the huge flocks of Passenger pigeons weren’t flying over anymore.
>Was there a time when there weren’t any endangered animals?

We have more animals now, not less. But I am not sure exactly how many because the tallies from 4000 years ago are still not finished. :smack:
