Production benefits

Conventional food production hides costs to the environment. Financial costs ignore the environmental cost.
Spirulina has no hidden environmental cost and offers more nutrition per square meter than any other food. It conserves land and soil and uses much less water and energy per kilo of protein produced than any other food.
Eating Spirulina and organic foods will improve your health and lower your medical bills compared to a diet rich in meat and conventionally grown foods.
The production of Spirulina does not cause pollution, soil erosion, water contamination or destruction of forest. Spirulina is grown without toxic pesticides and herbicides.

Its rapid growth means that Spirulina protein needs 30 times less land than soybeans, 40 times less than corn, and 300 times less than beef production.

Spirulina uses far less water per kilo of protein than any other food :
3 times less than soy, 6 times less than corn, and 50 times less than beef.

Spirulina requires less energy (including solar and generated energy) per kilo than soy, corn or beef. Its energy efficiency (food energy output per kg / energy input per kg) is 5 times higher than soy, twice as high as than corn and 150 times higher than beef.

Spirulina is a big oxygen producer.

Trees are the best land plants for fixing carbon, from 1 to 4 tons per hectare per year.

Spirulina is even more efficient, as it fixes 23 tons of CO2 per hectare per year and produces 16.8 tons of O2.
(with only the atmospheric CO2 and a 3.5 g/m2/d productivity ; 3.5*365 d*10,000 m2/1,000,000=12.8 tons of produced Spirulina and 12.8*1.8= 23 tons of absorbed CO2 et 12.8*1.31=16.8 tons of produced O2).

All these assets make Spirulina a high-value, environment friendly product, capable of being produced in disadvantaged regions. While commercial productions supply the food supplement market for millions of people over 6 continents, a lot of family or humanitarian production has arisen, enabling  local populations to be fed and combatting malnutrition in Africa, Asia and South America.
