地理

一部分亚马逊雨林的鸟瞰图。

南美洲的亚马逊雨林(60%面积位于巴西)位于亚马逊盆地,是全球最大的雨林,占地6百万平方公里(2百万平方哩)的平原和茂密的热带森林,居住着丰富的物种。但在过去30年,巴西政府将亚马逊州Amazonia)转为工厂区,及资助道路兴建计划、住屋及工业发展。

人类居所

亚马逊州人口并不密集。亚马逊河河畔有几个城市,并有一些散落的居地在内陆,但大多数人都居住于城市。部分森林被砍伐作为农地及大牧场,并有一些居住者种植橡胶巴西坚果

动物与植物

亚马逊州的动物及植物物种仍未被全部发现,原因是大部分地区依然未有人踏足。河里的物种数目亦无人知道。

地下河

2011年8月26日巴西国家测绘局在第12届国际地球物理会议上公布。在亚马逊盆地下2000至4000米的沉积岩底层,存在着一条流量巨大的暗河,跟亚马逊河同样长6,000公里,但比亚马逊河阔200倍,达200至400公里阔,以研究团队的组长命名,叫哈姆扎河(Rio Hamza)。
