Global warming and illegal immigration are two controversial political issues. I suppose it was only a matter of time somebody linked the two into a farcical argument, like how The Onion would. Only thing is, well, this letter in the Statesman Journal is no satire!
Wholesale immigration to places like Los Angeles is a prime contributor to "global warming." Fifty years ago it had the world's largest fishing fleet, largest vineyard and aircraft industry, and was first in agriculture production in the U.S.
That's gone now, and replaced by the world's largest matrix of vehicles, roads, and waste water systems.
