传统"基塘系统"是怎么做到接近"零废弃"的？
How did the traditional dyke-pond system get close to "zero waste"?
每一种"废物"都是另一环的原料：蚕沙、鱼粪、塘泥互为肥料与饲料，能量和养分多次利用，几乎不向系统外排废。
Every "waste" is another link's input: silkworm droppings, fish waste and pond mud serve as fertilizer and feed, reusing energy and nutrients so little leaves the system.

稻田养鸭为什么也能肥田又除虫？
Why can raising ducks in rice fields also fertilize and de-bug the paddy?
鸭子吃虫吃草，排泄的粪便直接肥田，踩水还能抑制杂草；一只鸭子集"除草机、施肥器、除虫员"于一身。
Ducks eat insects and weeds while their droppings fertilize the field, and paddling suppresses weeds—one duck is weeder, fertilizer and pest-control at once.

桑基鱼塘为什么被称为"循环农业"的典范？
Why is the mulberry-dike fish-pond a model of "circular agriculture"?
桑叶养蚕、蚕粪喂鱼、塘泥回田肥桑，几乎不浪费；物质在"桑—蚕—鱼—泥"之间转圈，是古人设计的闭环系统。
Mulberry leaves feed silkworms, their waste feeds fish, and pond mud fertilizes the mulberries—matter cycles through mulberry-silkworm-fish-mud, a closed loop designed by ancients.

稻田里养鱼（稻鱼共生），为什么能少用农药？
Why does rice-fish farming (rice-fish symbiosis) need less pesticide?
鱼会吃稻田里的虫和杂草，它们的游动还松土增氧；虫子少了，农药自然可以减下来，米和鱼还能一起收。
Fish eat pests and weeds in the paddy and their movement aerates and loosens soil; with fewer insects, pesticide use drops while both rice and fish are harvested.
