搜索网络,每分钟种一棵树

谷歌、雅虎和其他搜索引擎从广告商那里赚取大量资金,这些广告商付费在您搜索某个词条时弹出广告。一些更具社会意识的搜索引擎,如GoodsearchEveryclick,在您搜索或购物时会捐赠几美分给慈善机构。但是,一个于2009年启动的网站Ecosia,将其广告收入的惊人80%捐赠给一个在巴西雨林种植树木的项目,以应对当地迅速的森林砍伐。Ecosia已经变得足够受欢迎,最近 достигла 令人印象深刻的基准:它现在每分钟重新种植一棵树。

每天大约有20万人使用Ecosia,每24小时进行约50万次搜索。“由于种植每棵新树大约花费1美元,Ecosia的用户现在搜索和购物的频率足以资助每60秒种植一棵新树,”位于德国的Ecosia.org创始人克里斯蒂安·克罗尔说。

Ecosia将其资金发送给大自然保护协会运营的“种植十亿棵树”计划。该计划的目标是在2015年前通过种植十亿棵本地树木来恢复巴西大西洋森林;在Ecosia的捐款下,超过116,000棵幼苗已被种植到地下。克罗尔说,如果成功,“该计划每年有可能从大气中清除400万吨二氧化碳,这非常了不起。”

克罗尔将其公司定义为一家社会企业,因此它还抵消了发电厂产生的二氧化碳排放,这些发电厂发电以运行其Web服务器。它通过支持Myclimate.org的一个项目来实现这一点,该项目资助在马达加斯加销售太阳能炊具。这些炊具取代了旧的、常用的木柴和燃气炊具,减少了排放,并具有讽刺意味地减少了当地因燃料木材而造成的森林砍伐。

以每分钟一棵树的速度,Ecosia的捐款每周累计约10,000棵树。克罗尔的目标是保持足够快的增长速度,以便在明年重新种植100万棵树。通过Ecosia进行的搜索主要由雅虎提供支持,加上其自身的算法以及来自维基百科和必应的技术。广告由雅虎投放,雅虎与Ecosia分享一部分收入。为了方便起见,Ecosia还提供谷歌搜索,但根据克罗尔的说法,它们不会产生任何收入,因为谷歌不允许使用其应用程序赚取的资金转移给第三方。

克罗尔说:“如果Ecosia拥有像谷歌一样多的用户,当然,将会更快地种植更多的树木。我们可能有机会一劳永逸地结束森林砍伐。”
