Spirulina, A Superfood (Grow your own)

spirulina-powderSpirulina (Arthrospira platensis) is a blue-green algae (cyanobacterium), that’s very high in protein, vitamins, and amino acids. It grows in high pH (10-11) brackish water that is inhospitable to most other things, so it’s fairly impervious to being “polluted” by other strains. Basically a complete “superfood” that if you had to, you could exist on with only water. As a food additive, it balances your diet as it provides a complete nutritional, easy to process and absorb, supplement to what you already eat. It’s fairly easy to grow at home, with a 20 gallon aquarium, air pump, and some easy to make nutrients. Once you get a culture, you can spawn new tanks from that culture, so it’s self propagating. Below is a video of the process, a comprehensive tutorial document, and a source for basic starter supplies:

Beautiful Islands –The Three Sinking Livings

It was interesting to see the people, culture and environment of these fragile locations. Whether you believe climate change is man made or natural, it’s a good video to watch.


Beautiful Islands –The Three Sinking Livings
This movie looks at three beautiful islands, shaken by climate change: Tuvalu in the South Pacific, Venice in Italy, and Shishmaref in Alaska.

The islands all have different climates and cultures, but the people all love their native lands. The film, which took three years to shoot, focuses on their daily lives. It portrays festivals that foster ties among the people, traditional crafts which have been passed on for generations, and peaceful lives by the water. They are all disappearing by climate change.

When these people lose their homelands, their cultures and histories face “death.” Their lives in the midst of all the changes suggest where our future leads..

Director, Kana Tomoko purposely decided not to put any narration or music in this film. It is a two-hour trip around the world, listening to the sounds of waters and winds, accompanied by the children’s smiles. She wants you to sharpen your minds and feel what we are going to lose as climate change really (threatens) hits our planet.


Introduction to Permaculture

Will Hooker’s (Professor, NC State University) Introduction to Permaculture

Permaculture means “permanent culture,” (or “permanent agriculture”) and …”is the conscious design and maintenance of cultivated ecosystems that have the diversity, stability, and resilience of a natural ecosystem.” (Bill Mollison) This course will explore, through lectures, online discussions, and required projects, a design/thinking methodology that seeks to provide for our physical needs, food, water, shelter, energy, etc., while doing so in an environmentally friendly, sustainable manner.
