Dragon fruit is an exotic cactus that is found in Asia, Mexico, and parts of South America. It is not grown in North America or Africa, which is why the plant is not as common in these regions. Dragon fruit can be planted as ornamental plants, but they do bare delicious fruit that is rather tasty.

Which is why I was pleasantly surprised to see it growing pretty well in my Country Nigeria. Again, this is another confirmation to the humungous potentials of our country

Aquaponics combines two growing methods, aquaculture and hydroponics, to create a self-contained, well-balanced ecosystem. Fish are fed and raised in a tank and as gravity pulls the wastewater through a hydroponic garden, bacteria feed on the waste, breaking it down into essential nutrients for the plants to grow. The system then returns the cleaned water back to the fish reservoir so the process can begin again.

In this episode, Charles Collins shares his backyard aquaponic and hydroponic gardens where he's able to grow tilapia, leafy greens, peppers, herbs and so much more, all in the suburban desert. Together we grow!

ABOUT PARAGRAPHIC

A story is more than a title. We are a small team of independent filmmakers focused on emerging interests. We love exploring the wide landscape of these enthusiast communities through personal stories from their most passionate creators. The underdog, the obsessed, the misunderstood, the ones who have committed everything to their craft. For them it's more than a hobby; it's a way of life.

From garage bakeries and gourmet mushrooms to vertical farming and worm composting, these stories will elevate your understanding and deepen your appreciation.

Look beyond the impression.

Transcript of closed captions:

0:05: We are approaching a redwood tree. To animate a scientifically accurate leaf, artists studied the texture of a redwood leaf specimen on a glass slide at high resolution. They even counted the stomata, and used that exact count for this film!

0:25: These leaves would be measured on a centimeter scale. Throughout the animation, we will gradually zoom in to smaller scales.

0:40: As we approach a single stoma, we are now on a millimeter scale.

0:48: As we enter the interior of the leaf, we see many individual palisade cells. These cells are where photosynthesis takes place; they are translucent to allow sunlight to enter.

1:00: As we approach a single palisade cell, we’ll zoom down to the micrometer scale. The shapes inside the cell are organelles: the bright globules at the bottom are the Golgi apparatus; the yellow spotted tubes are endoplasmic reticulum studded with ribosomes.

1:09: That large, blue membrane surrounds the nucleus; the purple blobs are mitochondria.

1:18: The faint, yellow, spider-web structure of the cytoskeleton provides structure and support to the cell.

1:24: You are about to enter a chloroplast; inside you see flat, pancake-like membranous structures called thylakoids. This is where the light-dependent reactions of photosynthesis take place to produce ATP, the cell’s energy carrier molecule. way


1:38: The time scale has changed: the molecules are shown moving 1 million times slower than in real life!

1:42: As we near an individual thylakoid, the animation scale continues to shrink down to the molecular level, where things are measured in nanometers.


1:52: The green and blue bush-like structures are photosystems: clusters of proteins that absorb light energy from the sun and help convert it into the chemical energy that’s stored in the bonds of the energy carrier molecule called ATP.

2:03: The yellow-green, rotating structure is an enzyme called ATP synthase. This molecular machine facilitates the flow of protons down their concentration gradient from one side of the thylakoid membrane to the other, using the energy released in the process to assemble ATP.

2:16: The pulses of light in the thylakoid membrane in which the photosystems are embedded represent energized electrons being passed from one photosystem to another, passing along the energy which will be stored in the bonds of ATP (the classic “bucket brigade”).

2:26: The small “wigglies” are ATP molecules. Living things store energy in the bonds of the ATP molecules and then use that energy to conduct all the processes of life.

This animation is a model, and has its strengths and limitations. In order to model something well, visual artists have to make decisions about what to represent and how best to do so.

⁣When the Soviet Union collapsed in 1990, Cuba's economy went into a tailspin. With imports of oil cut by more than half – and food by 80 percent – people were desperate. This film tells of the hardships and struggles as well as the community and creativity of the Cuban people during this difficult time. Cubans share how they transitioned from a highly mechanized, industrial agricultural system to one using organic methods of farming and local, urban gardens. It is an unusual look into the Cuban culture during this economic crisis, which they call "The Special Period." The film opens with a short history of Peak Oil, a term for the time in our history when world oil production will reach its all-time peak and begin to decline forever. Cuba, the only country that has faced such a crisis – the massive reduction of fossil fuels – is an example of options and hope.
