Designer Biology: The Ethics of Intensively Engineering Biological and Ecological Systems consists of thirteen chapters that address the ethical issues raised by technological intervention and design across a broad range of biological and ecological systems. Among the technologies addressed are geoengineering, human enhancement, sex selection, genetic modification, and synthetic biology.

We argue that at least some corvids morally ought to be granted a right to bodily liberty in the US legal system and relevantly similar systems. This right would grant immunity to frivolous captivity and extermination. Implementing this right will require new legislation or the expansion of existing legislation including the elimination of various "pest" clauses. This paper proceeds in three parts. First, we survey accounts of the moral grounds of legal rights. Second, to establish an overlapping consensus supporting corvid (...) bodily liberty rights, we survey the empirical literature on corvid cognition. Third, we illustrate what a corvid right to bodily liberty might look like, by looking to recent developments in animal law, as well as previous advocacy on behalf of primates and cetaceans. (shrink)
