The wall of shame by Jo-Anne McArthur, Canada. Pinned to a white wall are the skins of rattlesnakes. Surrounding them are signed bloody handprints –triumphant marks of those who have skinned snakes at the annual rattlesnake round-up in Sweetwater, Texas. Each year tens of thousands of rattlesnakes are caught for this four‑day festival. In spring, wranglers use gasoline to flush the snakes out of their winter dens–apractice banned in many US states. They are kept in poor conditions before being brought to the festival and tossed into snake pits. They are then decapitated as entertainment for festival-goers, who pay to skin them. Proponents of the roundups claim they are needed to control the populations of venomous snakes to ensure the safety of people, pets and livestock. But opponents regard round-ups as an ecologically damaging, unsustainable and inhumane practice. What Jo-Anne found most unsettling about this image was ‘that so many of the bloodied handprints belonged to children’.
