THE symbol of the World Wide Fund for Nature is a giant panda. The panda’s black-and-white pelage certainly makes for a striking logo. But, though pandas are an endangered species, the cause of their endangerment is depressingly quotidian: a loss of habitat as Earth’s human population increases. A better icon might be an elephant, particularly an African elephant, for elephants are not mere collateral damage in humanity’s relentless expansion. Often, rather, they are deliberate targets, shot by poachers, who want their ivory; by farmers, because of the damage they do to crops; and by cattle herders, who see them as competitors for forage.
世界自然基金会的标志是一只大熊猫。大熊猫黑白相间的毛发无疑是醒目的标志。但是，尽管熊猫是濒危物种，它们濒危的原因竟然是令人郁闷的日常生活：随着人口数量的增加，栖息地的减少。更好的标志可能是一头大象：尤其是非洲象，因为大象可能不仅仅是人类的不断扩张所带来的附属伤害。而且通常，它们是被蓄意射击的目标，偷猎者想要它们的象牙；农民们，因为它们对庄稼所造成的损害；放牧人，他们把它们当做饲料的竞争对手。
In August 2016 the result of the Great Elephant Census, the most extensive count of a wild species ever attempted, suggested that about 350,000 African savannah elephants remain alive. This is down by 140,000 since 2007. The census, conducted by a team led by Mike Chase, an ecologist based in Botswana, and paid for by Paul Allen, one of the founders of Microsoft, undertook almost 500,000km of aerial surveys to come to its conclusion—though the team were unable to include forest elephants, a smaller, more reclusive type that live in west and central Africa, and which many biologists think a separate species.
在2016年8月，大象普查结果显示大约350000头非洲草原大象仍然活着。自2007年以来下降了140000。这次普查，由一个Mike chase领导的队伍、博茨瓦纳的生态学家、微软的创始人之一保罗艾伦实施，一共进行了大约500000千米的空中调查才得出的结论。但是团队无法把森林象列为研究的一部分。森林象是一种比较小，更封闭的物种，它们住在西部和中非，许多生物学家把森林象认定是一种单独的物种。
That most of the decline has been brought about by poaching is scarcely in doubt. Seizures of smuggled ivory, and the size of the carved-ivory market compared with the small amount of legal ivory available, confirm it. But habitat loss is important, too—and not just the conversion of bush into farmland. Roads, railways and fences, built as Africa develops, stop elephants moving around. And an elephant needs a lot of room. According to George Wittemyer of Save the Elephants (STE), a Kenyan research-and-conservation charity, an average elephant living in and around Samburu National Reserve, in northern Kenya, ranges over 1,500 square kilometres during the course of a year, and may travel as much as 60km a day.
大部分下降事由偷猎引起的，这一点是毫无疑问的。走私象牙的缴获和大规模的象牙雕刻市场，与小规模的合法的象牙交易相比，证明了这一点。但是栖息地的丧失也是很重要的。不仅是灌木到农田的转变，随着非洲的发展而建立的公路、铁路、和栅栏阻碍了大象们的迁徙。大象需要很大的空间。根据肯尼亚一个研究保护慈善机构《拯救大象》的乔治·维特耶尔说：“在肯尼亚背部的桑布鲁自然保护区，一头普通大象每年活动范围1500平方公里，每天迁徙到60km。
