  • This is a seed.

    這是種子。

  • It doesn't look like much right now, but if you...

    現在看起來和我們想像的不太一樣,不過…

  • Put it in the ground.

    放到泥土裡。

  • Give it some water.

    澆點水。

  • Fight off invaders and wait a little while...

    鏟除入侵者,並等待一段時間…

  • After a few weeks, with a little luck, you might end up with a head of lettuce.

    幾個星期後,再加一點點運氣,你會看到一顆生菜開始長出來。

  • That's a lot of work for a hundred calories.

    這一百大卡的前置工序很多。

  • But what if we had an easier way of doing things...

    那如果我們有更簡單的方法處理的話…

  • One that didn't require any soil, used much less water, and grew faster?

    有沒有一個不需要泥土、使用更少的水又可以生長得更快的方法?

  • One where food could actually grow itself?

    一個可以自己就會生長的食物呢?

  • By 2050, the world's population is expected to reach almost 10 billion people.

    至 2050 年,世界人口預計將達 100 億。

  • That's a lot more mouths to feed.

    要餵飽的人口可真不少!

  • But, only 11 percent of land is even suitable for agriculture.

    但卻只有 11% 的土地適合農業發展。

  • So, farmers will have to turn to innovative and more efficient farming practices for a solution.

    所以,農戶不得不轉向以創新、更有效率的耕作方法以解決問題。

  • One of the most promising is a method called aquaponics, which doesn't require any soil, and involves raising fish and plants together in a contained system.

    目前一個最有前景的方法是「魚菜共生」,這種方法不需要泥土,可以透過一個密封式系統同時養殖魚及植物。

  • There are several different setups you can use, but here's how the most popular method works. -[Deep water culture system.]

    可以有多種不同的設置,但以下這種裝配是最常見的。[深水栽培系統]

  • The process begins at the fish rearing tank.

    整個過程是先從魚池開始。

  • Here, highly adaptable fish like tilapia, are given plenty of fish food, which also leads to plenty of waste.

    這裡會有非常容易養殖的魚像是吳郭魚,因為會餵飼大量魚糧,所以會產生大量的廢物。

  • The solid waste is filtered out by flowing water, but the waterwhich is still full of ammonia from the fish excrementis mixed with special plastic pieces.

    這些固體的廢棄物透過流動的水濾出,但是水中仍然含有大量來自魚的排泄物的阿摩尼亞,會與這特殊的塑膠物料混合。

  • Naturally occurring bacteria grow on these surfaces, which helps convert the toxic ammonium in the water into nitrites and then nitrates.

    自然滋生的細菌會在這個表面上長成,那些細菌有助把手中有毒的阿摩尼亞轉化成亞硝酸鹽,然後再轉化成硝酸鹽。

  • Nitrates are basically plant food.

    硝酸鹽是植物最基本的養分。

  • So, the nutrient-rich water flows out into the growing area, where seedlings on floating rafts can absorb the food directly through their roots.

    因此,含有大量營養的水流至生長區,浮在水上木排的蔬菜幼苗會透過根部吸收所需的食物。

  • No soil required.

    完全不需要泥土。

  • Above them, energy-efficient LED lights are adjusted to provide the optimal color spectrum.

    而且在植物的上方裝有可調節的節能 LED 燈以提供最佳色譜。

  • -All of this comes together, helping the plants grow up to twice as fast as land crops. -[Visible light spectrum, vegetative growth, flowering period.]

    綜合以上,有助植物比一般土地農作物的成長速度快兩倍。

  • And because the plant roots purify the water, the cycle can start all over again.

    再加上植物能淨化那些水,因此整個過程又可以再重新開始。

  • Commercial systems can yield up to 12 times as much produce per square foot as traditional farming methods.

    這種商業系統每平方英尺的產量比傳統耕作方法最高可高達 12 倍。

  • Leafy greens like lettuce are the easiest crops to grow, but they often focus on more valuable herbs like basil and mint.

    如生菜這類的多葉蔬菜是最容易栽種,不過他們反而會集中栽種羅勒和薄荷葉等更有價值的香草。

  • Aquaponics is one of the most sustainable agricultural systems, but it still has a long way to go before becoming a go-to farming method.

    魚菜共生是最可持續發展的農業系統,但距離成為實際可行的耕作方法實在還有很長一段路。

  • New developments are continuing to make the process more customizable, automated, and efficient than ever.

    新的發展將繼續使作業過程能比以往更客製化,自動化和高效能。

  • Who knows, in the future your salad might even be grown by a fish!

    誰知道在不久的未來,你的生菜沙拉也許是由魚養殖出來呢!

  • What food would you grow in your aquaponic system?

    不知道你們會透過魚菜共生系統種植什麼呢?

  • Let us know in the comments below.

    歡迎在下面留言告訴我們!

This is a seed.
