Is there a moral requirement to assist wild animals suffering due to natural causes? According to the laissez-faire intuition, although we may have special duties to assist wild animals, there are no general requirements to care for them. If this view is right, then our positive duties toward wild animals can be only special, grounded in special circumstances. In this article I present the contribution argument which employs the thought that the receipt of benefits from wild animals is one such (...) kind of special circumstance. If this argument is correct, then the circle of moral agents required to assist some wild animals is significantly widened. (shrink)

Libertarians concede that non-autonomous sentient beings pose a problem for their theory. But, while they acknowledge that libertarianism denies non-autonomous sentient beings basic moral rights, libertarians have overlooked how their theory also denies non-autonomous sentient beings basic moral powers. In this article, I show how the libertarian entitlement theory of justice, specifically, the theory for the original acquisition of holdings, denies non-autonomous sentient beings the moral power to originally acquire or make property. Attempts to avoid this problem by appealing to (...) interests or preference autonomy are likely to be unsuccessful. (shrink)

Urban animals can benefit from living in cities, but this also makes them vulnerable as they increasingly depend on the advantages of urban life. This article has two aims. First, I provide a detailed analysis of the concept of captivity and explain why it matters to nonhuman animals—because and insofar as many of them have a (non-substitutable) interest in freedom. Second, I defend a surprising implication of the account—pushing the boundaries of the concept while the boundaries of cities and human (...) activities expand. I argue for the existence of the neglected problem of pervasive captivity, of which urban wildlife is an illustration. Many urban animals are confined, controlled and dependent, therefore often captive of expanding urban areas. While I argue that captivity per se is value-neutral, I draw the ethical and policy implications of harmful pervasive captivity. (shrink)
