The oceans hold about 321 million cubic miles or 1.34 billion cubic kilometers of water, which is roughly 97 percent of Earth’s water supply. This also includes the seawater weight which is about 3.5 percent dissolved salt and other essential minerals like chlorine, magnesium, and calcium.
More than 80% of the ocean is unmapped and unexplored, which makes it an interesting area of our planet. It is also intriguing for some marine enthusiasts as to how many species there are yet to be discovered. The ocean is also the home to some of the world’s oldest living organisms like Jellyfish, horseshoe crabs and more.
Oceans have not been immune to climate change and global warming. The year 2020 marked the oceans’ hottest year on record, and warmer waters have created multiple consequences, from changing colors, to endangered marine organisms like corals. Rising sea levels, more frequent powerful storms, plastic pollution and much more has threatened the health of oceans #worldoceanday2021#oceanfacts#nantwichlionsclub
