To Eat or Not To Eat

The world faces both the depletion of fossil fuels and a shortage of food. Ironically, more and more countries are turning to some crops such as cassava and corn to produce cheaper fuel. But, in the process, those crops, who feed millions of people around the world, are beginning to grow scarce as food, especially in the poorer countries, where they are most needed. Unless this growing trend is soon reverted, we may have fuel for all sorts of uses, but we won't have the energy to do anything with it, being too weak from hunger.

The obvious choice is to develop solar, water and wind-powered alternatives to these so-called biofuels, so that we don't have to choose between eating and lighting our homes.

Low, Low Tactic

Here's a significant little item. Wal-Mart, the world's biggest retailer, has announced that it will increase the number of stores in which it will have weapons for sale. Although it had cut back in that department in 2006, slow sales have convinced that selling rifles, shotguns and ammunition in half of its stores is the way to increase profits. So, the next time you, as an American citizen, feel like going on a shooting rampage against family, friends or coworkers, just go to the nearest Wal-Mart, where, for a "low, low everyday price", you'll be able to pick up a nice little arsenal, courtesy of the Second Amendment to the Constitution of the United States of America. Happy hunting!

Don't Know, Don't Care

I's been called "the dumbing down of America", a recognition of the downward spiral of American education. The average person in the U.S. is ill-informed about national and international affairs. Thus, they are easy prey for demagogues who trade in false patriotism, fear and prejudice. A recent study of political views confirms just how ignorant and gullible is the typical U.S. citizen. For democracy to work, there has to be a well-informed citizenry. The men of 1776 knew this, and pinned their hopes on it for their political experiment to succeed. They would be extremely disappointed in 2011. Ironically, with all the freedom of information and multiple outlets to obtain it, the American people have very little political culture and their participation in the democratic processes is far from what it should be in an advanced society.

Columbus' Curse

Although it wasn't altogether new, the 1992 celebration of the 500th anniversary of the discovery of America made it fashionable to malign Columbus big time.  From Indians from all over the Americas, who still hold a  grudge against the Spanish conquistadores , to latter-day revisionist historians, everybody got into the act of pissing on the erstwhile "Grand Admiral."  Year after year we keep hearing the same old story: he wasn't the first to come to America (everybody and his brother had been here before); if he was, it was only because he had some maps given to him by somebody else (or stolen) from somebody else; it was just a fluke, etc. It has become politically correct to badmouth Columbus. I suppose all those purists would have preferred that he stay home, leaving us all in a  perpetual Garden of Eden, untouched by the European culture.  This is nonsense.  No matter if, objectively, he wasn't the first to set foot on this part of the world or whatever adv
