00:00:00.370 --> 00:00:02.700
水は必須なものです
生命にとって

00:00:02.700 --> 00:00:05.320
農業や食料にとって　またシャワーにもです

00:00:05.892 --> 00:00:07.832
多くの場合　水ははるか遠くから来ます

00:00:07.832 --> 00:00:10.434
例えば
南カリフォルニアの水の半分以上は

00:00:10.434 --> 00:00:12.276
コロラド川から汲み上げられています

00:00:12.406 --> 00:00:15.115
山岳地帯を越えて運ばれます 来ます

00:00:15.115 --> 00:00:17.429
町や農地で使われるために

00:00:17.809 --> 00:00:19.997
しかしながら　
降水量や気温が変化していますので

00:00:19.997 --> 00:00:21.621
科学者は大干ばつを予見しています

00:00:21.621 --> 00:00:23.242
米国の西部で起こることを

00:00:23.242 --> 00:00:24.866
そして　その長期的な干ばつの多くは

00:00:24.866 --> 00:00:26.862
コロラド川の真上を中心としています

00:00:26.862 --> 00:00:29.844
それは意味しています
ロサンゼルスのような大都市や地方の農場が

00:00:29.844 --> 00:00:31.907
水の供給が滞るかもしれません

00:00:32.047 --> 00:00:34.680
今回のテーマでは
干ばつの恐ろしさの理由を学び

00:00:34.680 --> 00:00:36.451
そして教訓を学びたいと思います

00:00:36.451 --> 00:00:38.466
米国南西部に住み続けて来られた方々からの

00:00:38.466 --> 00:00:39.854
数千年の間

00:00:45.384 --> 00:00:46.701
集水地域とは

00:00:46.751 --> 00:00:50.248
降水が集まり特定の水域にぶつかる場所です

00:00:50.418 --> 00:00:51.905


00:00:51.905 --> 00:00:54.281


00:00:54.621 --> 00:00:56.864
