複雑な生態系を持つアマゾン地域は、米国本土とほぼ同じ大きさに広がります。アマゾン川の水量は毎秒5700万ガロン（約2億1,600万リットル）で、これはニューヨーク市の人口750万人が使用する水量の1年分に相当します。
動植物も多く、地球上の顕花植物の4種に1種はアマゾンに生息していると言われ、アマゾン川とその支流には、欧州のすべての川を合わせたより多くの種類の魚が生息している可能性があるとされています。このほか、世界最大のアリクイ、アルマジロ、淡水ガメ、クモ、そして最大の齧歯類（体重90kg以上）、ナマズ（113kg）、ワニ（500kg以上）などが生息しています。約3,900億本の樹木を有する熱帯雨林は、大量の二酸化炭素を吸収し、地球の気候安定に重要な役割を果たしています。ブラジルと東南アジアの深刻な干ばつや、米国、欧州、中国での降雨パターンの変化も、アマゾンにおける森林破壊と関係があります。アマゾンはまた、何百万人もの人々の居住地でもあります。西部には、土地と川に完全に依存している約70の孤立した未接触の部族が集中しています。彼らは西半球で最も疎外された民族と言われ、自分たちの森とその未来に関する発言権を持っていません。
40年にわたりアマゾンやその人々、動植物を研究してきた生態学者で自然保護の専門家が、アマゾンというかけがえのない生態系と、それが直面する課題について、興味深い概観を提供します。
The Amazon is a land of superlatives. The complex ecosystem covers an area about the size of the continental U.S. The Amazon River discharges 57 million gallons of water per second--in two hours, this would be enough to supply all of New York City's 7.5 million residents with water for a year. Its flora and fauna are abundant. Approximately one of every four flowering plant species on earth resides in the Amazon. A single Amazonian river may contain more fish species than all the rivers in Europe combined. It is home to the world's largest anteater, armadillo, freshwater turtle, and spider, as well as the largest rodent (which weighs over 200 lbs.), catfish (250 lbs.), and alligator (more than half a ton). The rainforest, which contains approximately 390 billion trees, plays a vital role in stabilizing the global climate by absorbing massive amounts of carbon dioxide--or releasing it into the atmosphere if the trees are destroyed. Severe droughts in both Brazil and Southeast Asia have been linked to Amazonian deforestation, as have changing rainfall patterns in the U.S., Europe, and China. The Amazon also serves as home to millions of people.
Approximately seventy tribes of isolated and uncontacted people are concentrated in the western Amazon, completely dependent on the land and river. These isolated groups have been described as the most marginalized peoples in the western hemisphere, with no voice in the decisions made about their futures and the fate of their forests. In this addition to the What Everyone Needs to Know® series, ecologist and conservation expert, Mark J. Plotkin, who has spent 40 years studying Amazonia, its peoples, flora, and fauna. The Amazon offers an engaging overview of this irreplaceable ecosystem and the challenges it faces.
