Aquaponics is the idea of producing vegetables and fish in the same closed system. It combines aquaculture, or fish farming, with hydroponics, a way to grow plants without soil. Supporters see aquaponics as a way to increase world food supplies and reduce climate change, groundwater pollution and overfishing.
生态水培技术（Aquaponics）是一种在同一个封闭系统中种植蔬菜和养殖鱼类的理念，它结合了水产养殖和水培的特点。水培是一种不用土壤种植作物的方法。支持者认为，生态水培技术是增加全球粮食供应，减少气候变化、地下水污染和过度捕捞的一种解决之道。
 
Sylvia Bernstein says the idea is as old as nature.
Sylvia Bernstein称生态水培技术理念和大自然一样历史悠久。
 
SYLVIA BERNSTEIN: "Aquaponics is really a recirculating wetland system, so it's happening right on the banks of our lakes."
Bernstein：“生态水培技术实际是一种湿地循环系统，这种系统就在我们的湖泊岸边。”

Ms. Bernstein grew plants in water with a chemical fertilizer for years. Then she discovered she could use wastewater from fish to grow organic vegetables and fruit.
Bernstein女士多年来一直使用化肥在水中种植作物。后来她发现她可以使用养鱼的废水种植有机蔬菜和水果。

SYLVIA BERNSTEIN: "Honestly, I was very skeptical and just couldn't believe that something as simple as fish waste could become a complete fertilizer. So I had to actually see a system that was in a friend's basement. But when I did, it changed my life."
Bernstein：“说实话，我对鱼废物可以作为肥料这样简单的事情很是怀疑。所以直到我在朋友家地下室看到这个系统后才相信。但当我看过这一系统后，它改变了我的生活。”
 
That was three years ago. Ms. Bernstein built her first system with her son outside her home in Boulder, Colorado. Today she raises tilapia and trout. She feeds them once a day. Her plants grow in containers. There are no weeds in her aquaponics garden, and no need to worry about watering.
那是三年前，Bernstein女士和她儿子在科罗拉多州博尔德市的家中建造了第一个系统。今天她养殖了罗非鱼和鳟鱼，并每天喂养它们一次。而作物在容器中生长。在她的生态水培花园中没有杂草，也不用担心浇水。

SYLVIA BERNSTEIN: "I, just this morning, pulled four radishes and some lettuce for lunch. In my greenhouse right now, I grow all sorts of herbs, tomatoes, peppers."
Bernstein：“就在今天上午，我拔了四根萝卜和一些生菜做午餐。现在我在温室中种了各种生菜、西红柿和辣椒。
 
Ms. Bernstein started her own business called the Aquaponics Source. She has a YouTube channel, teaches aquaponics at the Denver Botanic Gardens and recently published a book.
Bernstein女士开创了自己名为Aquaponics Source的生意。她在Youtube网站开设了一个频道，在丹佛植物园教授生态水培技术，最近还出版了一本书。
