In the western United States, pesticides used in agricultural and urban areas are often detected in streams and rivers that support threatened and endangered Pacific salmon.Although concentrations are rarely high enough to cause direct salmon mortality, they can reach levels sufficient to impair juvenile feeding behavior and limit macroinvertebrate

Models of machines, including the increasingly miniaturized, digitally controlled machines of modern computers, inform models of human and animal behavior.What are the impacts of this exchange? This paper builds on theoretical discussion to produce an artistic exploration around this idea.The paper uses known limits on computation, previously prove
