                                Every time you breathe, one of your lungs fills with oxygen from forests, while the other is filled by oxygen from phytoplankton, a type of plankton. The question of whether plankton is good or bad for humans is nuanced; it is a critical life-sustaining force for the planet, yet certain species and conditions can pose significant health risks through toxins and environmental disruptions.
