    這個國家90%以上的食物都要進口,即使它能把貧瘠的土地變成肥沃的農田,一位接受CNN採訪的土壤科學家說,它可能會改變脆弱的沙漠生態系統,當以前沒有的東西突然有了,但如果這項技術每年得到資助和有效管理,近3000萬畝肥沃的土壤隨之退化。

    在乾燥的國家,如加利福尼亞州,內華達州和亞利桑那州,你知道,不斷增加的溫度,延長的乾旱時期,能夠確保我們有一點水,實際上是保留在土壤中,將是非常寶貴的,重要的農民前進。

    但許多居民很高興他們繞過了建設它的問題,因為現在項目已經全面展開,它讓人們既想停下腳步,又想去兜風,還想來一場海底探險,讓他們的眼睛交通盯著既是馬路,又是頭暈、車暈、輪胎暈的路口蘭登C。
