The green sludge that could transform our diets
bbc ^

One potential alternative food source – both for humans and the animals we eat – is algae.

Humans have eaten macroalgae, like wakame and nori seaweed, for thousands of years. But recently attention has turned to the nutritional and environmental potential of their microscopic cousins.

Microalgae are tiny protein-rich organisms found in both fresh and seawater. They typically contain essential amino acids, essential fatty acids, including omega-3, omega-6 along with omega-7, along with vitamins, such as A, D and E. The nutritional content varies depending on the type of microalgae, but two currently dominate the market for human consumption. The first is a group of species (known as a “genus”) called Chlorella. The second is the genus Arthrospira, more commonly known as “Spirulina”. Both are rich in nutrients.

Last year, Tzachor visited a small-scale microalgae farm in Iceland run by Israel-based company Algaennovation. The farm uses geothermal electricity to power LEDs that light transparent tubes called photobioreactors.

The site, which started out as a trial, has been fully operational since July 2019. Instead of being cultivated for human food, the algae grown at Algaennovation is fed to fish in aquaculture, replacing unsustainable fishmeal – wild fish caught in the millions of tonnes every year in order to feed farmed fish. Algae make a great alternative because they are rich in omega-3, which fish can’t produce themselves, and so need to get it from their diet.

Tzachor says while the system is based on geothermal energy currently, it could also work using hydroelectric power plants, meaning it could be replicated in many other parts of the world.

Caves for us, mansions and castles for them.

No problem, as long as it tastes good. Develop an algae that tastes like a chocolate milkshake and I’m in.

THIS is what they want the huddled masses to eat instead of meat.

WAR is coming, people. Blood in the streets, "up the horses' bridles." Get ready.

These days, real truth usually gets banned . . . unfortunately

I thought Obama said algae could potentially replace petroleum as an energy source. Now we’re going to be eating the stuff, too?!

Saw Zappa live at the Capital Theater in Jersey. Weird and wonderful show. Truly a great showman

Their most worshiped god that they believed in was their god Huitzilopotchli. Huitzilopotchli was the god of sun, war, human sacrifice, and patron of the city Tenochtitlan.https://jacieaztecs.weebly.com/beliefs—values.html,
They worshiped death.

Don’t give the Obamas any bright ideas! That handjob was trying to run Navy ships on it and a Michelle judge would order it on school lunch menu.

I’d rather have Metamucil.

Puts out lots of vegetable oils...may be able to convert to biodiesel...or run straight on modified engines and fuel systems. I also read there is s fungus which produces an oil close to biodiesel physical properties. No money in it yet..but it could fill in nicely for fossil oil when mods necessary have been elucidated.
