Personally, I would choose A. <span>Are the conveniences we have today worth the effect they will have on Earth tomorrow?
B. should be in the middle of the paragraph, C. would also be in the beginning/middle as a way to lead into how humans are truly polluting the earth, and D. is the conclusion. </span>
