From a netfriend, before I set off for the U.S. next week:

Prologue:

Time was when an American about to go abroad would be warned by his
friends or the guidebooks not to drink the water; but times have
changed, and now a foreigner coming to this country might be offered
the following advice:

If you visit American city,
you will find it very pretty.
just two things of which you must beware:
don’t drink the water and don’t breathe the air.

Pollution, pollution,
they got smog and sewage and mud.
turn on your tap and get hot and cold running crud.

See the halibuts and the sturgeons
being wiped out by detergents.
fish gotta swim and birds gotta fly,
but they don’t last long if they try.

Pollution, pollution,
you can use the latest toothpaste,
and then rinse your mouth with industrial waste.
