> A key concern is the health risk for the birds: cigarette filters contain toxic chemicals, and handling them may pose a risk to the crows. Corvid Cleaning acknowledges this issue and is carefully testing which types of litter are safe for collection. > Moreover, there is a philosophical debate about sustainability: is it ethical to turn natural foraging behavior into a “job” for animals? I wonder what the crows think? Whether they would notice that the health risks and stop on their own accord. It’s probably not yet a “job” unless humans manage to remove all other food sources for crows, thus forcing crows to do this for their survival, then it becomes a “job”.
