Get ready to set sail, because June 25 is the Day of the Seafarer. This is day for seafarers of all stripes, from Coast Guards, to Navies, to every fisherman and marine biologist and cruise ship captain. If your job involves a large quantity of salt water, then this day is dedicated to you. The first documented sea voyage was made around 3200 BCE, and was bankrolled by the Egyptian Pharaoh Snefru (he also built at least three pyramids during his reign). Today, over 90% of global trade is done by sea, since it is still the most cost-effective way to transport goods. Marine biologists and oceanographers from every country have dedicated their lives to learning more about the ocean depths, and humans from every walk of life keep going to the sea to explore the planet.
