When John Todd was a child, he loved to explore the woods around his house, observing how nature solved problems. A dirty stream, for example, often became clear after flowing through plants and along rocks where tiny creatures lived. When he got older, John started to wonder if this process could be used to clean up the messes people were making.
After studying agriculture, medicine, and fisheries in college, John went back to observing nature and asking questions. Why can certain plants trap harmful bacteria (细菌)? Which kinds of fish can eat cancer-causing chemicals? With the right combination of animals and plants, he figured, maybe he could clean up waste the way nature did. He decided to build what he would later call an eco-machine.
The task John set for himself was to remove harmful substances from some sludge (污泥). First, he constructed a series of clear fiberglass tanks connected to each other. Then he went around to local ponds and streams and brought back some plants and animals. He placed them in the tanks and waited. Little by little, these different kinds of life got used to one another and formed their own ecosystem. After a few weeks, John added the sludge.
He was amazed at the results. The plants and animals in the eco-machine took the sludge as food and began to eat it! Within weeks, it had all been digested, and all that was left was pure water.
Over the years, John has taken on many big jobs. He developed a greenhouse — like facility that treated sewage (污水) from 1,600 homes in South Burlington. He also designed an eco-machine to clean canal water in Fuzhou, a city in southeast China.
“Ecological design” is the name John gives to what he does. “Life on Earth is kind of a box of spare parts for the inventor,” he says. “You put organisms in new relationships and observe what’s happening. Then you let these new systems develop their own ways to self-repair.”

当约翰·托德还是个孩子的时候,他喜欢探索他的房子周围的树林,观察大自然是如何解决问题的。
例如,一条肮脏的溪流在流过植物和沿着微小生物居住的岩石后,往往会变得清澈。
当他长大后,约翰开始怀疑这个过程是否可以用来清理人们正在制造的混乱。
在大学里学习了农业、医学和渔业之后,约翰回到观察自然并提出问题。
为什么某些植物会捕获有害细菌(细菌)?哪些鱼可以吃致癌的化学物质?
他认为,有了动物和植物的正确结合,也许他可以像自然一样清理垃圾。
他决定建造一种后来被他称为生态机器的机器。
约翰为自己设定的任务是清除一些污泥中的有害物质(污泥)。
首先,他建造了一系列相互连接的透明玻璃纤维储罐。
然后,他四处来到当地的池塘和小溪里,带回了一些动植物。
他把它们放在坦克里,等待着。
渐渐地,这些不同种类的生活相互适应,形成了自己的生态系统。
几周后,约翰又加了一些污泥。 他很惊讶生态机器里的植物和动物把污泥作为食物,并开始吃它!
几个星期之内,它都被消化掉了,只剩下纯水了。
多年来,约翰做了许多大的工作。
他开发了一个类似温室的设施,可以处理南伯灵顿1600个家庭的污水(污水)。 他还在中国东南部的一个城市福州设计了一种清洁运河水的生态机器。
“生态设计”是约翰对他所做的事情的称呼。
“地球上的生命对发明者来说就像一盒备件,”他说。“你把生物体建立新的关系,观察正在发生的事情。然后你让这些新系统开发出自己的自我修复方式。”
