Eh, I'm a pedantic, boring nerd, but I checked and I cannot save myself from forumsplaining... In reality the estimates are 600K humans killed by other humans every year vs 1M killed by mosquitos. To be fair we are still our most dangerous enemy, because we are destroying the Earth ecosystem, and there can be catastrophic wars. But the mirror was more about the fact that we are the most dangerous predator of other animals.I think they're the biggest killers of humans among non human animals. But like fernandel says, nothing comes close to humans. I remember as a little kid, going to the Bronx zoo and there was some exhibit, with a cage for the most dangerous animal. It just had a mirror.
Moreover, I thought that we are also the only species that kills themself (i.e. there are zero mosquitos killing other mosquitos), instead this is not 100% correct. Scimpanze, from which we derive, kills other isolated scimpanze of other groups, for protecting the borders of their territories, and more rarely they have organized wars with other groups. The same for Wolfs, but probably less than Scimpanze. The records for mammals is for Meerkats: 19% of all the deaths of Meerkats are done by mothers killing the newborns of other mothers. Male lions have the the same behavior, but with lower numbers. Prehistoric humans estimate are: 5% of deaths caused by homicide/wars. So, we are in a very restricted category of self killing species, but this behavior is also in Scimpanze. So it is also biological, not only cultural.
With the excuse that it is biological, I propose some coordinate actions at Linux meetups. At the signal, when Strauss's "Also sprach Zarathustra" start, we will extract the bone club!
