Highest levels of photosynthetic activity
WebA review entitled „Recent developments in the production and utilization of photosynthetic microorganisms for food applications“, focusing on a different topic than the previous published one. WebAlthough photosynthetic organisms remove some of the carbon dioxide produced by human activities, rising atmospheric levels are trapping heat and causing the climate to change. Many scientists believe that preserving forests and other expanses of vegetation is increasingly important to combat this rise in carbon dioxide levels.
