A) In secondary ecological ethics, we distinguish a proximate moral ought, ecologically informed, operating through natural law, but which is preceded by an antecedent moral ought that is classical. Injunctions to recycle are of this kind. B) in primary ecological ethics, ecosystemic evaluation has informed even the antecedent moral ought, and the descriptive and prescriptive arise together.
