TRADUCCIÓN:

Un niño nada en las algas cubiertas de aguas de la costa de Qingdao, China (mapa) en el año 2011, sólo uno de tantos lugares del mundo donde la proliferación de algas son un problema creciente. (Imágenes relacionadas: "Fotos: Nadador bucea en gruesas algas verdes ")
Con un estimado de siete mil millones de personas y creciendo, el hambre en el mundo sigue aumentando como su población. Por el advenimiento de los fertilizantes y cultivos de alto rendimiento, los cultivadores han ayudado a mantener el ritmo de la demanda de alimentos.
Pero hay un cultivo intencional floreciendo en todo el mundo que no siempre es tan beneficioso. Organismos semejantes a las plantas microscópicas llamadas algas prosperan por el exceso de nutrientes, como el nitrógeno y el fósforo se encuentran en los fertilizantes-que se abren paso desde los patios y campos, produciendo florecimiento que a veces se pueden ver desde el espacio.

So maybe we should send skimmers out and gather up the algae and turn it into bio fuel? just a thought.....

".... enormous algae blooms that can turn the water green or red. .."

Why not brown due to Diatom Algal bloom?

Has anyone ever seen water brown with Diatoms?

@Mallimodugula BhaskarI am not entirely sure, but I think because of the density of diatoms, although they have blooms they don't stay suspended that long and instead sink very quickly.  Also, their growth can be limited by the availability of silica, which normally is most abundant (and other conditions are favorable) in the spring in middle latitudes due to high levels of runoff.

Could you eat the algae or do they have any medicinal qualities?

Can they be turned into compost?

Could useful drugs or chemicals be refined from them.

Could you capture methane gas from them as they decompose?

It seems like a bonanza rather than a problem.

@Chris BarkerCommon toxins produced by algae blooms in the ocean are neurotoxins that can—in high enough quantities—shut down a person's heart, stop their breathing, cause them to lose their short-term memory, or send them into convulsions, he added.

We cannot have INFINITE GROWTH in a FINITE World, this is INSANITY.  The world is seriously OVERPOPULATED.  Thomas Malthus was RIGHT!!! People better start practicing some serious Birth Control SOON.  But they WON'T, Malthus was CORRECT.  Bob Burnitt

@Bob Burnitt  I am very sorry to inform you. We DO NOT have over population. There is plenty of land if we learn to manage it properly and lift the many restrictions this Administration has demanded on the private sector.

@Tom Marantette @Bob Burnitt Bob is correct, do you not understand... there is NOT enough work for the PEOPLE ... there is a HUNGER issue people are STARVING because there is NOT enough FOOD to FEED all the People on the Planet... THERE is a MAJOR OVER population problem.... WE are like a cage of Rats left unchecked...allowed to breed out of control,.  we have become the  parasite on the face of this planet.... we have OUT GROWN our  cage... we are becoming Savages toward each other.... it is out of control and  ...

What's the status of algae-based biofuels? Maybe "algae trawlers" could haul it ashore and make lemonade out of this climate lemon problem.

The solution is to grow useful algae that are consumed by fish, then we would have fish blooms instead of algal blooms.
