wild rubber的意思|示意

New innovations increased efficiency and production doubled every two years. Rubber could be produced at only a fraction of the cost of collecting wild rubber in Brazil.

新的革新技术提高了效益，橡胶产量每2年翻一番，在那里生产橡胶的成本只是巴西采集野生橡胶的成本的很小一部分。

Thus, harvesting the babassu coconuts is more similar to farming than other activities involving more widely dispersed wild-growing trees or vegetation, such as rubber-tapping in the Amazon jungle.

因此，收割巴巴苏椰子与其他诸如砍伐亚马逊丛林的那种收割生长在更野外的分散生长的树或者植物相比，更与耕种相似。
