It is the stick man (and woman).
In the case of most species, they are endangered either by habitat loss or by hunting.
But in the case of stick men, it is just that they are particularly accident-prone.
There is evidence (from SS Great Britain in Bristol) that this state of affairs has been going on for at least 150 years.
However, there is good news that breeding colonies have been established on public transport …
and in other public places.
But also, that all sorts of relationships are valued.
So perhaps the future for stick men is not so grim after all.
