要在美洲种植橡胶树很难，因为有一种叫做“叶枯病”的病害存在，橡胶树的间距必须很大（译者注：防止病害传播）。

Growing Hevea in the Americas is hard. A disease called leaf blight means the trees have to be spaced widely.

即使在亚洲，虽然目前还没有叶枯病，但种植新的橡胶树就得砍伐雨林，是公众不赞成的。

Even in Asia, currently blight-free, planting new rubber trees often means cutting down rainforest, to general disapproval.
