Is Spirulina Growing Environmental Friendly?

Someone asked me if Spirulina growing was environmentally friendly. Well, as spirulina grows, it does take in sunlight and carbon dioxide from the environment. In this photosynthesis process, spirulina produces oxygen to our atmosphere. So spirulina growing can be deemed as environmental friendly. In that sense, spirulina is no different like all other plants. Nevertheless, when human being and animals consume edible vegetables, fruits, plants and spirulina, through metabolism, carbon dioxide is than released back to the atmosphere. There is not much we can do about this natural cycle. However we can help the environmental by paying attention to the packaging materials of spirulina. Broadly speaking, spirulina on the market is either packed in glass bottles, or in plastic materials. We can do our part in helping the environment by selecting glass bottles over plastic packaging. Glass is a recyclable while plastic is difficult to be recycled. And as referred to in an earlier blog, spirulina packed in glass bottles remain fresher than those packed in plastic. Quality wise, therefore, spirulina packed in glass is better than plastic containers.
So we are in a win-win situation when we choose spirulina packed in glass bottles.

Pound of pound, one acre of cultivated spirulina could produce 8000 pounds of protein, whereas an acre of grazing land produces 46 pounds of protein in beef.

Whether spirulina is environmental friendly or not, it is in your hand.
