4 REASONS THE WORLD IS HOOKED ON COAL

Black –you don’t know the meaning of the word until you’ve been down a mine shaft,” yells my friend Nat over the noise of machinery. Gazing at the yawning hole in front me, I start to wonder if I really want to find out what Nat means.

                                               [1] STEEL PRODUCTION


Over 70 percent of the steel produced worldwide is processed by coal-burning blast furnaces. In addition, the makers of bricks, tiles, cement, plastics, dyes, and explosives use chemicals derived from coal.

                                               [2] POWER PRODUCTION


By far the biggest consumer of coal, however, is the power industry. Australia generates 84 percent of its electric energy from coal-fired power plants. In China, South Africa, and Denmark, approximately three quarters of the electricity is generated from coal. The United States relies on coal for over half of its electric power. Worldwide, more than a third of the electricity produced comes from coal.

                                               [3] DOMESTIC APPLIANCES


To put it another way, if you own an electric stove, you consume approximately half a ton of coal a year. Two tons of coal will power your electric water heater for the same period, and your electric refrigerator will devour a further half ton annually.

                                                  [4] MASSIVE RESERVE

Scientists estimate that one million million tons of coal remain in the earth’s “cellar” –enough to last hundreds of years at the present rate of consumption.

                                 COAL’S FUTURE-A HOT ISSUE



COAL AND POLLUTION: smoke and small particles from burning coal cause more than 50,000 new cases of chronic bronchitis a year in 11 of [China’s] large cities, “states a united Nations Environment Programme report. The technology to remove much of this pollution is available but is considered too expensive for many power-starved countries to purchase.


COAL AND CLIMATE CHANGE: The burning of coal already produces over two thousand million tons of carbon dioxide gas each year. And coal is forecast to remain the second-largest source of carbon emissions, at about 34 percent in 2020. Many see these statistics as cause for alarm.

PLASTIC SURGERY; PROS AND CONS

-
“Prior to my nose operation, I suffered a lot because of teasing. I did not want a nose that was special, just one that suited me. I am very happy with the result, and I would do same thing all over again.”-Elea.” “Why should I submit to standardized ideas of good looks? With surgically altered body parts. I would feel like fake money. Not genuine.”-Matthew. “Everyone must decide for himself or herself. It is very difficult for someone else to judge.”-Imma “Whoever is prettier than I am must be wearing makeup.” In Germany, that humorous saying has long served as a sort of defense for people who worry that their looks are less than perfect. In some lands nowadays, though, the saying might well be updated to: “Whoever is prettier than I am must have gone under knife.” Indeed, cosmetic surgery is becoming commonplace. “The days are over when cosmetic surgery was reserved for the rich,” reports the Swiss newspaper Neue Zurcher Zeitung, adding: “Two trends have emerged: More and more me

RUSSIAN BLINI

-
RUSSIAN BLINI The French have their CREPES, the Scots their BANNOCK, and the Americans their FLAPJACKS. So it comes as no surprise that Russians have their own version of the PANCAKE –the BLIN, which is a staple with a long history. The ancient Slavs used blini for food sacrifices in their pagan rituals and saw in blini an appropriate symbol of round, warm, golden sun. Women who had recently given birth were fed blini. These were also served at weddings and at funerals, so they figured in peoples’ lives from birth to death. Russians today usually make blini with wheat flour, but other flours can also be used. RECIPE FOR BUCKWHEAT BLINI INGREDIENTS 120 grams buckwheat flour 120 grams wheat flour 20 grams butter, melted 2 eggs 720 milliliters or so of milk 30 grams sugar Pinch of salt PREPARATION: Mix buckwheat flour with 240 milliliters of milk. Heat another 240 milliliters of milk, and add it to the batter,

OUR BODY: THE PERFECT MACHINE - When you reflect on the remarkable abilities of various animals, do you sometimes feel a twinge of envy? Perhaps you wish that you could soar like an albatross, swim like a dolphin, see like an eagle, or run like a cheetah. Yes, animals have some amazing abilities. But so do we! Indeed, the human body has been described as the perfect machine. Of course, we are much more than a machine. We have creativity, curiosity, imagination, and ingenuity –qualities that move us to devise machines that enable us to do virtually anything we set our minds to. https://mysticrealityfacts.blogspot.com/2014/12/the-magic-in-your-fingers.html We can fly, even beyond the speed of sound; navigate above or below the surface of vast oceans; gaze some 14 billion light-years into space; peer into the living cell; and design medicines, therapies, and technologies that help us diagnose and treat diseases. Even with little or no external assista
