“Meeting this challenge involves not only providing sufficient calories for every person, but also assuring a balanced diet that includes the protein and nutrients that are essential to good health. In a newly published study, we explain how marine microalgae could be a sustainable solution for solving global macro-hunger.

Problems with Current Food Production Systems

“The current Western diet requires vast amounts of land, water and energy, is heavily polluting and is a major contributor to climate change. Providing nutritious food for an ever-growing global population with increasing per capita demand is pushing our current food production system beyond its limits.

“Livestock production is replacing forests with cropland and pastures for meat and animal feed. Nitrogen and phosphorous fertilizer used to grow feed grain and other crops is degrading soils and creating biological dead zones in some 400 estuaries around the world.” –William Moomaw and Asaf Tzachor (How Marine Algae Could Help Feed the World).
