> humanity is almost certainly immune to extinction, there are too many of us See https://en.m.wikipedia.org/wiki/Passenger_pigeon https://en.m.wikipedia.org/wiki/Passenger_pigeon > The pigeon migrated in enormous flocks, constantly searching for food, shelter, and breeding grounds, and was once the most abundant bird in North America, numbering around 3 billion, and possibly up to 5 billion. > A slow decline between about 1800 and 1870 was followed by a rapid decline between 1870 and 1890. In 1900, the last confirmed wild bird was shot in southern Ohio.
