三、答案：①-⑤ GEBCF
解析：①根据设空处的前一句“Researchers using satellite images found at least ten percent trees cover more than one billion hectares of farmland.”可知,此处在说树木在农田中的覆盖量的问题,G项那几乎是世界上农田的一半。符合上下文语境。故选G。
②根据设空处前后可知,此处在说树木在世界各地的覆盖率的排名。E项“接下来是撒哈拉以南的非洲,然后是东南亚。”符合语境。故选E。
③根据设空处的前一句“And it also found that climate conditions alone could not explain the tree cover in different areas.”可知,此处在讲述造成不同地区树木覆盖率不同的因素。B项附近的人口规模也不能意味着人和树木可以共存。是在讨论人口和树木的关系,符合上下文语境。故选B。
④根据设空处后一句“The problem, he says, is that policy makers and planners have been slow to recognize this and to support such efforts.”可知,问题在于政策制定者和规划者迟迟不承认这一点,并不支持这种努力。C项“他说农民们正在采取行动独自保护和种植树木。”讲的是现在农民做出的努力,与后文承接,故选C。
⑤根据设空处所在段的内容可知,这里在讲述树木的用途, F项它们还有助于防止土壤流失和保护水供应。也是树木的一个重要作用,所以F项内容符合上下文语境,故选F。
