In dismissing the White House Climate Change Report, the “Chicken Little” letter proves the old adage that "a little knowledge is a dangerous thing.”

The writer is correct that scientists, decades ago, did predict the world would run out of oil and food. But as with all biased thinking, drawing the conclusion that scientists can’t be trusted is a mistake. The world has not run out of oil and food precisely because we listened to the scientists and averted disaster by taking preventative action.

Decades ago, against conservative resistance, liberals who believed in science mobilized government to take action. Fortunately, they mandated stricter fuel mileage standards, which saved motorists millions of dollars in wasted gas, and also extended existing oil reserves. Fortunately, they devised improved agricultural methods and food distribution systems, which lowered the cost of food, reduced waste and postponed worldwide food shortages.

Today we face similar warnings from scientists. Will we listen, or bury our heads in the sand?

Immigration law must

adjust with the times

In 1846 the first members of my family arrived in America following a lengthy voyage from Germany. Their first steps on U.S. soil were in lower Manhattan, at a place called Castle Gardens, the portal of entry that preceded Ellis Island, which didn’t open until 1892.

Like most other immigrants, they came here to find a better life. They came with little other than the clothes on their backs, a few dollars, a few pieces of cheap luggage and the dream of life in America. When they arrived, the population of the United States was a little over 17 million, far less than the 326 million population of today. There was no such thing as income tax, nor was there Medicaid, Medicare, Social Security, or the resulting burden of a $21 trillion debt we have now.

I tell this little story to remind everyone that even the “shining city upon a hill,” the great melting pot of the world” has a limit. The laws governing legal entry to our country, as uncaring as they may sometime seem to some, are there to help sustain what makes the United States the most desired place in the world to live.
