Plankton has been a long-time obsession of mine. Not only are some of its forms like delicate snowflakes from outer space, but it is also the basic building block of the ocean’s food chain. Plankton plays a crucial role in the regulation of our planet’s atmosphere. Plankton creates half of our planet’s oxygen, as well calcareous plankton actually sequesters carbon-dioxide, which means that it absorbs co2 from our atmosphere and when it dies it sinks to the bottom of the ocean allowing the co2 to emerge slowly, over hundreds of years, back into the atmosphere. The above photograph is of plankton that I captured in Okinawa.
