To Study The Biological Carbon Sequestration Using BHOPAL Lakes Microalgae

Microalgae represent efficient photosynthetic microorganisms with the potential to serve as natural air purifiers by generating oxygen and reducing CO2 levels. Microalgae can play an important role in reducing carbon dioxide (CO₂) levels in cities. They grow fast, use sunlight, and absorb CO₂ during photosynthesis. When used in small urban spaces—like near traffic signals, on building walls, and in decorative fountains—microalgae can clean the air and improve the environment. This paper explains how microalgae can be used in such city setups, their advantages, and their challenges. It also discusses real and possible examples of building façades, fountains, and traffic junctions using algae-based systems to trap CO₂ and create cleaner air.
