70亿

一月 5, 2011

据联合国人口近期调查报告指出,很可能在2011年中后期,地球人口总数将达到70亿。在2011年的某一天里,当我们与往日一样来回于睁眼与闭眼之间时,第70亿个生命便悄然降生。世界人口从1999年超过60亿至今,只花了12年就将轻松到达70亿的数字,而未来这一数字的增长过程将会大多数发生在发展中国家。

 

即使如欧洲,或者是亚洲日本这样的区域人口总量出现了不增反减的趋势,但依然无法改变世界总需求增强的现实,作为世界人口大国亿级俱乐部成员之一的中国,也将在2025年被印度默默超过,目前印度人口增长趋势为:1553万/年,27万/月,4万2/天,768/小时,29/分钟。从这一增长数据看,2025年之前,印度必将成为世界人口第一大国,而菲律宾也将很快会加入到该俱乐部中来。

1798年,英国牧师兼经济学家托马斯·马尔萨斯关于“人口规律”的言论已经被世界上某些地区验证:在战争、疾病与饥饿作用下减少人口数量之前,人口增长速度一定比食物供应的速度快。在自然资源面临短缺的未来,人口总数巨大的发展中国家以及贫困国家的自身压力会越来越大,在这些国家,不仅要让人们维持基本的生活,摆脱贫困,同时还要减少这些地区因巨大的人口数量对自然环境造成的影响。

国家地理频道在我们即将迎来第70亿个生命之时,发起了共同关注该话题的倡议,每一个生命的诞生都有其特别的意义,而作为地球上主要生命群体之一,我们肩负着无法回避的生存责任,70亿乃至未来更多的生命都在牵动着地球的每一次呼吸。
