Asia is the most populated continent and by far the most diverse. As a continent that is home to the Middle East, the India subcontinent, and the Orient, one can only imagine how many thousands of languages, types of cuisine, cultures might exist. Asia has all types of unique wildlife from the rainforests in southeast Asia to the frozen Siberia in Russia. Asia also has more preserved history than anywhere else in the world. Temples that are thousands of years old exist in Japan and China while the ancient cities in Iraq’s Babylon or Yemen’s Aden still thrive.
