I propose a model for the development of citizen rights based on the a
dvance of political and social rights and apply it to contemporary cla
ims regarding environmental rights. In terms of this ''claims and atte
nuations'' model, I sketch the roles of environmental philosophers and
activists, the media and public opinion, and political insiders in th
e development of positive rights. I then predict a weakening of enviro
nmental claims and a marginalization of environmental philosophies as
environmental claims are secured as positive rights.
