Today (April 22nd) is Earth Day (see previous post), and this cartoon by Kal from The Economist provides a timely reminder, if one was needed, about the various threats to the global environment. In the cartoon shows what can best be described as a juggernaut destroying everything in its path, as an assortment of wild animals flee for their lives.
The various global threats are fairly clear, but there are one or two points worth commenting on. The comment made by the two birds features a play on the verb 'advance' and the adjective 'advanced'. The 'most advanced species' is, of course, humans. The remark is meant to be ironic, as is the 'Happy Earth Day' flag. The driver has his head in a bag of sand, which is a reference to the idiom 'to have/hide/stick/bury one's head in the sand'. This means to refuse to think about an unpleasant situation. • Teachers can't just hide their heads in the sand and not try to find out why students aren't doing better.
