The article discusses the urgent need for alternative food sources due to growing food security challenges exacerbated by overpopulation, pandemics, political conflicts, and climate change. Microalgae are highlighted as promising alternative protein sources due to their high protein content, essential amino acids, and environmental benefits. However, challenges like cultivation costs, protein extraction, and sensory qualities need to be addressed. The article advocates for the use of systems biology and artificial intelligence (AI) to optimize the growth and protein yield of microalgae, leveraging omics data and computational models for improved outcomes.
