The cartoon's purpose is to show how large political leaders will ignore a problem, such as climate change, because the "cost" in terms of money is too large. The leader claims he "used to agree" with the fact that climate change is a real problem, however after discovering the amount of money needed to fix that problem he decided to support the fact that it is a "hoax." I agree with the cartoon in the sense that large and powerful political leaders are unwilling to pay the cost for problems, solely because they don't want to pay the amount. I also agree that instead of saying the facts, some leaders will say things that will only benefit them, factual or not.

The Abame clan gets torn. It happened because most of the clan converted to Christianity and followed the white men, but some of them are stuck to their own traditions and refuse to follow the white men. Especially Okonkwo does not want to convert.
