1) What is the cartoonist's actual message?
2) What strategies does he use to convey his message? (focus on Obama's attitude, on his words, on the posture of both characters (facing each other, facing the reader, looking and pointing east, going in opposite directions), on the nature of this document, etc.)
3) What do you know about the history of the US in terms of environmental policy?
4) Judging from the fourth picture and the date this cartoon was drawn, have things evolved ever since Obama was elected? And is the situation likely to dramatically improve in a near future? Why? (both in terms of economic impact and habit)
