History of Mother Ocean Day

Have you ever wondered what the Earth would be like without the ocean? How would life be, or would there even be life? Scientists are not sure how water came to Earth but they know it has been around for four billion years. The oceans have seen it all: the formation of continents, the day of creation, volcanic rage, tectonic plate battles, the split of continents, reptile evolution, extinction events, mammalian conquest, and human blunders and legends. It is one of the oldest things on Earth. It was there before humans came, and it will be there long after our time.

The ocean is also an enigma that refuses to share its inner workings. We’ve explored higher percentages of cosmic bodies than we’ve explored the depths of the ocean. The ocean is the source of most of the oxygen that we breathe and the rain we get. Without the ocean, the climate as we know it today would not exist. Most of human history can be easily understood by understanding the sea routes we took in the past. Our explorations through the vast oceans increased our willpower and our drive to create and innovate. The ocean is also home to the largest ecosystem on Earth, with one-quarter of all life calling it home. Mother Ocean Day is a day dedicated to appreciating the importance of the oceans on our planet. The day was founded by the South Florida Kayak Fishing Club.
