Human beings can use only a small fraction of Earth’s water. In school, we were taught that most (specifically, 71 percent) of the planet’s surface is covered in water. While that’s true, humans can use only 0.007 percent of that water, according to National Geographic. That’s because only about 2.5 percent of Earth’s water is fresh water, and only 1 percent of that is accessible. The rest makes up glaciers and snowfields.

A deficiency of vitamins is a common issue that people face, as the human body requires several essential vitamins, and individuals often overlook the intake of some of them.

There are parts of Africa in all four hemispheres. For people whose education was largely focused on the Western world, it may be surprising to find out exactly how huge the continent of Africa is. For instance, it spans all four hemispheres and covers nearly 12 million square miles.

The Philippines consists of 7,641 islands. The Philippines is an archipelago, which means it’s made up of a group of islands—7,641 islands, to be exact. That figure does not include the thousands of sandbars and other landforms that emerge during low tide.

The circulatory system is more than 60,000 miles long. If a child’s entire circulatory system—we’re talking veins, arteries, and capillaries—were laid out flat, it would stretch for more than 60,000 miles, according to the Franklin Institute. By the time we reach adulthood, our bodies have become home to approximately 100,000 miles of blood vessels.
