In the following sentence:
无妨 means "might as well", "there is no harm", or "no matter".
However, it then makes no sense, since the meaning would become something like the following:
Every person is the world citizen, so should never have the idea that low-carbon life is irrelevant with yourself. That is, others make a low-carbon life while I make a high-carbon life is also no harm (无妨).
This does not make sense, as 无妨 seems to be positive connotation for the sentence 我自己过“高碳生活”, which is incompatible with the author's point of view, which proposes the low-carbon life.
So what is the meaning of 无妨 here? Is my understanding here correct in the first place?
