Do you agree with Joe DesJardins that business has a moral responsibility to ensure that its activities are ecologically sustainable? Examine in detail the ethical justification DesJardins gives for this claim. Is he successful in his attempt to base hi s defence of sustainability on “the same values that underlie traditional market economics”? Relate your discussion to the broader corporate responsibility debate, making sure that you refer to at least two sources other than DesJardins.
