Main Article Content
Abstract
Seaweeds exhibit a remarkable capacity for bioremediation, acting as natural filters that sequester pollutants like heavy metals, nutrients, and organic matter from waterways. This inherent ability translates into promising wastewater treatment technologies, offering a sustainable alternative to traditional chemical-intensive methods. Seaweeds perform bioremediation feats, drawing out toxins and paving the way for revitalized ecosystems. The environmental benefits of seaweeds extend beyond pollution mitigation. These efficient photosynthesizers act as potent carbon sinks, capturing atmospheric CO2 and mitigating the effects of climate change. A vast number of bioactive compounds lies within their cellular walls, possessing a range of potential therapeutic properties. Seaweed extracts find their way into functional foods, enriching our diets with antioxidants, anti-inflammatory agents, and prebiotics. These nutritional powerhouses hold the potential to enhance immunity and overall well-being, offering a natural path towards improved health. Seaweed extracts are being investigated for their role in developing novel drugs and diagnostics. Imaging tools and biocompatible materials derived from these marine marvels could revolutionize personalized medicine. However, unlocking the full potential of seaweeds necessitates addressing challenges associated with large-scale cultivation and processing. Sustainable practices and cost-effective methods are crucial for ensuring the economic viability and ecological integrity of seaweed utilization. This review explores the
multifaceted applications of seaweeds, highlighting their ability to remediate polluted environments and contribute to human health while acknowledging the challenges associated with their large-scale utilization.
