从盐水中找一个配偶
2017-08-11 16:26:48 中国青年网
同时,可以建立大规模的海洋保护区,在有些地方可以使用渔业的替代行业。比如,帕劳是第一个在所有领海范围内禁止鲨鱼商业捕捞的国家,过去捕捉鲨鱼割下了鱼鳍只能获得几百美元,但是一条活着的鲨鱼可以产生将近200万美元的价值。因为定居在这里的鲨鱼种群能推动潜水行业。经估算,活的鲨鱼能够给帕劳带来至少80%的GDP。研究表明,许多海洋物种活着比死了更有价值。
当然,也并不是所有的生态旅行都可行,还需要其他方式补偿,比如说印尼有一个社会企业家创造了一种新的商业模式,帮助渔民变为珊瑚养殖户。最开始是度假村的发展摧毁了当地的珊瑚礁,现在他们的谋生方式是帮助建立珊瑚礁,卖给水族馆,这比炸掉珊瑚礁的收入更高。
这本书每一章的开头都有些小片段,借助了情爱小说的方式,运用想象和夸张的艺术手法来表现海洋的繁殖,读起来饶有趣味,但其主题内容都是严谨的科学知识。这是一个比虚拟更为神奇绚丽的世界:《海底总动员》里小丑鱼爸爸马林千辛万苦帮助儿子尼莫在失去妈妈后成长的故事,在真实的海洋世界中根本不会发生。但如果让大自然来写这个故事,尼莫妈妈从世界上消失后,尼莫爸爸马林会做出一个父亲应该做的事——改变自己的性别,成为家族中占据主导的雌性小丑鱼。
作者玛拉. J. 哈尔特是珊瑚礁生态学家,曾任蓝色海洋研究所研究员,目前担任非营利组织“鱼类的未来”的研究带头人,致力于海洋环境保护与海洋生物保护事业。她亲眼目睹了满月的时候,石星珊瑚会在一个完美的仪式般的同步中释放千百万个配子,这种仪式已经持续了上千万年,作者目睹了大自然一年年如此优雅精确的循环,体会到一种神圣的职责:要让人们认识到海洋和我们的关系,即使恢复海洋的繁育有种种的曲折,依然要怀抱希望。
