Oceans, Part 5

For my last ocean blog, I wanted to end with a truly mind-blowing thought. Phytoplankton, the microscopic, plant-like cells that live in Earth’s oceans (and lakes) provide FIFTY PERCENT of the oxygen in the Earth’s atmosphere. That’s right. Even though we can’t even see them without a microscope, these minute organisms prove us with 50% of the air we breathe. Not only that, they take in carbon dioxide (this is the same process of photosynthesis that plants and trees go through). And if that isn’t enough, they also form the base of marine food chains.

Next time you are at the ocean, look at a drop of water on your skin – there will be thousands of phytoplankton in that single drop. Then, take a deep breath of air and thank these microscopic organisms!
