You cannot jump right to community harm reduction before first addressing individual harm reduction. Therefore, if a newly widowed woman struggles to eat, she is released from the obligation of having an eco-perfect diet not because eating ethically is unimportant, but because when the real-world choices for someone are eating dairy or eating nothing, it is always the ethical choice to eat. It is always the ethical choice to encourage that person to eat whatever they can manage. Harm reduction is always ethical.
