Let's take a trip around the Earth

About 13.7 billion years ago, all the mass of the universe existed as a single point. Then ... the Big Bang! The universe came into existence and began expanding. Then, the Earth formed 4.54 billion years ago and about one billion years after, life appeared. While, Humans only evolved about 200,000 years ago.

About 4.6 billion years ago, our Solar System formed. It's home to our sun and eight planets -- Mercury, Venus, Earth, Mars, Saturn, Jupiter, Uranus, and Neptune.

The Sun is enormous -- it would take 1.3 million Earths to fill up the Sun. Earth is the third planet from the Sun and the only planet in the Universe known to harbor life. Please take really good care of it as its our only home.

Most of Earth's surface is covered with water which bestows it the charming blue, with plants adding green, and glaciers embellishing white. But only a tiny portion of the water is drinkable.

One shall never feel along in this world -- about 7.6 billion humans live on this blue planet. Politically, the world has about 200 countries and each has its own culture. It is important to embrace divesity and celebrate differences.

The U.S. habitats 300 million people which makes it the third largest country by population, behind China and India. Drag or rotate the earth to see comparisons between countries. The countries with orange bars have more than 100,000,000 residents.

These bars visualized the GDP of each country and partially displayed the global inequality. Europe has the most countries with high GDP. The economy of the United States remains the largest in the world in terms of GDP. In fact, America's poor are among the world's wealthy.

Education is the key to everything that is good in our world today. With a 97.7% literacy rate, the U.S. is among the most educated countries. But the short bars show that there are many people, especially those in developing countries have no access to education.
