Algae is the perfect food plant. It doubles cell mass every twelve hours, depending on the strain.

Photosynthetic organisms in the sea yield most of the oxygen in the atmosphere, take up and store vast amounts of carbon dioxide, shape planetary chemistry, and hold the planet steady.

Improving photosynthesis, although a highly important goal towards securing food security, cannot change the superiority of the combination photovoltaic cells/electric battery/electric engine.

As a result of the carbon-dioxide enrichment of the Earth's atmosphere, plants are now growing faster. Furthermore, global warming lengthens the growing season and increases net rainfall.

Like the ocean, land plants hold about three times as much carbon as the atmosphere. While oceans take many centuries to exchange this mass with the air, flora take only a few years.

Everybody is looking for a naturally occurring algae that is going to be a miracle cell to save the world, and after a century of looking, people still haven't found it.

Because of the low photosynthetic efficiency and the competition of energy plants with food plants for agricultural land, we should not grow plants for biofuel production. The growth of such energy plants will undoubtedly lead to an increase in food prices, which will predominantly hit poorer people.

Biological energy comes from the sun. Light energy harvested by photosynthesis in chloroplasts and phototropic bacteria becomes stored in carbohydrates and fats. This stored energy can be released by oxidative metabolism in the form of adenosine triphosphate (ATP) and used as fuel for other biological processes.

With the exception of autotrophic bacteria, the green, or chlorophyll-bearing, plants are the only living forms on this planet capable of synthesizing organic matter out of inorganic elements and simple compounds.

Ultimately, the only wealth that can sustain any community, economy or nation is derived from the photosynthetic process - green plants growing on regenerating soil.
