Sunday Comic Tackles the Environment

I opened the paper this Sunday to see an interesting "For Better or For Worse." The comic usually sticks to relationships and household life, but this week focused on the environment.

I'm not quite sure what the message is. The first eight panels seem to say, "We all need to do what we can." But I'm not sure if the final panel's message is, "Personal action can't be effective unless we regulate emissions," or a more despondent, "Why bother?"
