But my search for ancient systems and Indigenous technologies has been different.

但我对古代系统和本土技术的探索有所不同。

I've traveled the world studying ancient innovation, and what I've found are Indigenous technologies from living cultures that are still in use.

我周游世界研究古代创新，我发现的是仍在使用的来自现存文化的本土技术。

On the edges of Calcutta, flanked by a smoking escarpment of the city's trash and ribboned by its highways, an Indigenous technology of 300 fish ponds cleans its water while producing its food.

在加尔各答的边缘，两侧是冒着烟的城市垃圾悬崖， 高速公路环绕着 300 个鱼塘， 采用本土技术在生产食物的同时净化水源。

What amazes me is that while an individual acadja is pretty insignificant, when it's multiplied by 12,000,it creates an Indigenous technology the scale of industrial aquaculture, which is the greatest threat to our mangrove ecosystems ...

令我惊讶的是， 虽然一个个体 acadja 非常微不足道，但当它乘以 12, 000 时， 它创造了一种具有工业化水产养殖规模的本土技术，这是对我们红树林生态系统的最大威胁. . . . . .
