• The first German serviceman killed in the war was killed by the Japanese (China, 1937)

• The first American serviceman killed was killed by the Russians (Finland 1940)

• 80% of Soviet males born in 1923 didn't survive World War II

• The highest ranking American killed was Lt. Gen. Lesley McNair, killed by the US Army Air Corps

• Between 1939 and 1945 the Allies dropped 3.4 million tons of bombs, An average of about 27,700 tons of bombs each month

• There were 433 Medals of Honor awarded during World War 2, 219 of them were given after the recipient’s death

• The youngest US serviceman was 12 year old Calvin Graham

• Number of people killed in the war: 45 million

• Number of Europeans left homeless by war: 12 million

• Number of Americans who joined the armed forces: 12 million

• Number of Americans who moved to take on war jobs: 15 million

• Number of B-17 "Flying Fortress" bombers built: 13 thousand

• Amount of post-war aid given by U.S. to Western Europe: $17 billion

• Reparations paid by Italy after war: $36 million

This was the largest and most expensive war ever, as well as the most difficult to settle. The world remained politically unstable, major cities had been turned to rubble by bombings, and modern weapons and brought death to millions of people.

World’s Most Beautiful River

Caño Cristales, a river in Columbia’s Sierra de la Macarena, is as moody as it is beautiful. Come a bit too early in the dry season, and you’ll just find a parched river bed. Come a bit too late in the wet season, and everything will be flooded and more inaccessible than unusual. But come just at the right time, in the first few days of the wet season, and you’ll witness a magnificent spectacle of rainbow colors in a river that’s nicknamed the “most beautiful river in the world”.


Caño Cristales’ waters flow from the plateau south of the Sierranía de la Macarena, a national park and mountain range that is a sanctuary for many animal and plant species. The rugged terrain is coupled up with many archaeological sites and caves that have not been explored. The archaeological sites have pictograms and petroglyphs that date as far back as the pre-Columbian times. The river is the parks central feature. The 100 km long and 20 m wide river is the national park’s central feature.


The river bed and river rocks are covered with green and brown mosses and algae during most of the year. At the onset of the wet season in early October and early April, however, they receive enough moisture and sunlight to unfold a most spectacular array of colors ranging from deep red, yellow and pink to blue, green and black.


However, as the wet season progresses, it is not possible to view that many colours. As the wet season progresses, the water levels become deeper and the river currents faster, obscuring the bottom of the river and therefore not letting the much needed sunlight through for the river’s many mosses and algae.

Blue Whales

Blue whales are the largest animals ever known to have lived on Earth. These magnificent marine mammals rule the oceans at up to 100 feet (30 meters) long and upwards of 200 tons (181 metric tons). Their tongues alone can weigh as much as an elephant.

Blue whales reach these mind-boggling dimensions on a diet composed nearly exclusively of tiny shrimplike animals called krill. During certain times of the year, a single adult blue whale consumes about 4 tons (3.6 metric tons) of krill a day.
Each blue whale's skin markings are unique, like fingerprints that distinguish one whale from another. Blue whales often appear to be a pale bluish-gray color, but they can also appear silvery gray or tan, depending on the light.

When a whale dives, the twin flukes of its tail leave a "flukeprint"—a smooth, raised, circular slick on the surface of the water. The flukeprints of blue whales are large and longlasting due to the force of the blue whales' deep dives. The smooth patch can linger on the surface of the ocean long after the whale is gone.

Blue whales are believed to have excellent hearing, which helps them navigate the dark ocean environment. A blue whale's age can be estimated by examining the waxlike plug in its ear after death. A set number of layers are added to the plug each year. Scientists estimate that the average lifespan of blue whales is 80 to 90 years.Blue whales' eyes are quite small in relation to their massive bodies—about the size of a grapefruit. They are thought to have limited eyesight, but little else is known about their vision.

A blue whale's blowhole is like a huge pair of nostrils, each large enough for a toddler to crawl in. When a whale surfaces, it exhales, then inhales enough air to fill a van, all in 1.5 seconds. The spray from a blue whale's blowhole can shoot as high as 30 feet (9 meters) into the air. The force of a blow can create a thunderous sound, audible from several miles away.

An adult blue whale's heart can weigh close to 2,000 pounds (900 kilograms). It beats only once every ten seconds and can be detected from two miles (three kilometres) away.

Blue whales can be found alone or in groups in every ocean on the planet, but their exact migratory patterns remain a mystery. Some populations appear to migrate very little, while others make incredible, annual trans-oceanic journeys from polar waters to equatorial waters. In the Northern Hemisphere, blue whales can be seen regularly in the Gulf of St. Lawrence and off the coasts of Monterey and Baja, California. The largest remaining population of blue whales is considered to be the eastern North Pacific population.
