Algae and Global Warming

A bold idea is suggesting to increase the spread of ocean-dwelling algae in order to fight global warming. The premise is simple: algae produce their nutrients through the process of photosynthesis (like most plants do), and CO2 is a vital component in this process, thus more algae will result in less CO2 in the atmosphere.

One way to encourage the reproduction of ocean-dwelling algae is by transferring cold and nutrient-rich water from inner layers of the ocean up to the surface in a process called upwelling. While upwelling happens naturally, speeding it up is what vertical tubes aim to do.

Whether this can truly help our planet is yet to be proven. But it’s nevertheless amazing to hear about all these out-of-the-box ideas that people conjure when facing global warming.
