How did Noah’s Ark float?

REUTERS/Fatih Saribas (TURKEY)The story of Noah's Ark in The Bible is widely read as an allegory and discoveries of a stunning range of species of wildlife raise questions, for those who believe in the account as literal truth, about how they all crammed aboard.

The total number of species of animals and plants on the planet, according to biologists, may well range up to the tens of millions. About 1.8 million have been identified so far -- many of them are plants and fish that Noah did not take along to escape the flood, according to the Book of Genesis.

Even the Ark, with its three decks, would have quickly filled if Noah took at least two of all living creatures as God instructed Noah in the Book of Genesis. 

Modern maritime standards are that cows, for instance, need about 2 square metres each on ocean voyages in pens of about half a dozen. The Ark was about 140 metres (460 feet) long -- the world's biggest container ships are now almost 400 metres long.

One 2004 poll showed that 60 percent of Americans read the story of Noah's Ark as literally true.

Church protest chases Donald Duck from Noah’s Ark

Donald DuckDonald Duck has been expelled from Noah’s Ark.

To be more precise, a Donald Duck film clip has been removed from a replica of Noah’s Ark in the Netherlands. That came after a local church protested that the film being shown to children visiting the ark strayed too far from the Bible story.

Some background first — a Dutch evangelical named Johan Huibers has built a 50-meter (164-feet) long replica of Noah’s Ark to teach children the Bible story that most didn’t know anymore. Finished last spring, it is about one-fifth of the size mentioned in the Bible but looks like the ship portrayed in religious art. Huibers and his staff have been docking it in Dutch port cities and towns including Amsterdam and Rotterdam for several weeks at a time so local children can visit it.

One of his teaching methods was a clip from the Walt Disney film Fantasia 2000 showing the Ark story. Donald Duck appears in it as Noah’s hapless helper, herding the animals onto the ship and busying himself with odd jobs during the voyage. In another non-Biblical twist, Daisy Duck also appears, but neither she nor Donald knows the other made it aboard before the Deluge struck. Their reunion on dry land is a classic Disney happy end.
