The online ocean science community has been vocally skeptical about the Ocean Cleanup, a device that aims to physically remove plastic pollution from the ocean. Drs. Kim Martini and Miriam Goldstein published a technical review of its feasibility over at Deep Sea News, and Andrew asked some important questions that have yet to be answered. Also, be sure to read environmental journalist Chris Clarke’s thorough overview of these concerns.
Overall concerns include a lack of understanding of the problem (including but not limited to the fact that much of the harmful ocean plastic is small and well-dispersed), insufficient structural integrity for a large object that will be deployed in the open ocean (which would result in the object breaking and creating even more ocean garbage), and the fact that this device is designed to aggregate objects of a certain size to remove them from the water but cannot distinguish between plastic and living things.
Mainstream media coverage has been noticeably less critical of the Ocean Cleanup, often presenting the idea as revolutionary and it’s creator as a genius.

宣传也很重要啊,她宣传的主要是阻止气候继续变暖的紧迫性,气候变暖主要来源是温室气体的过多排放,这来源主要是化石燃料的燃烧,用煤发电,还有交通行业这些,这就需要政府来制定更严格的排放标准,并且奖励/投资新能源,这些都不是普通人能干的活啊。号召普通人少用点电根本没有政府制定法律效率高。所以她说要用democracy的力量让政府不能再忽视这个问题的紧迫性,我觉得她是抓住了这个问题的主要矛盾。再说为什么不能hold government accountable同时自己也尽量节能?

就是这样的。垃圾不是消失了,只是换了一个地方,积攒着惩罚。
世界的Consumers 太多,problem solvers太少。把垃圾从海里捞起,至少可以解决一些当前问题
做的人太少,批评的人太多。 你看看 前几天那个 环保少女, 看看大多数世界的人怎么肯定她的热情,看看华人上的人怎么挖苦讥笑的。 才是个10几岁的孩子,有这种信念和坚持,不就足够了不起,足够值得肯定了吗?
这个环保少女才是典型的动动嘴皮子到处批评做得太少。她对这个世界到底有哪些真正可执行的建设性的帮助?
这个小孩子是真正动手操作了的,真正做了事情,让世界有了改变的。
16岁正是千禧一代,是消费狂欢的买单一代。他们是继承世界和所有的Problem的一代,就像孩子继承了不负责任父母的所有负债。所以他们的愤怒很可以理解。那些毒舌16女孩的,大都是热情消费世界的人,对于自己造成的潜在成本,选择无视无知。
唤起全世界公众对环保议题的关注,哪怕只有一天的关注。就这一点,就是你一个成年人一辈子都做不到的了。
我们这一代成年人的不作为或者少作为,的确给后代遗留下很多问题。环境问题,污染问题,枪支问题,药品滥用问题。
那些毒舌16女孩的,大都是热情消费世界的人,对于自己造成的潜在成本,选择无视无知。
几年前俺娃有个project就是采访这个 Boyan Slat 的,他的solution真的是 so simple so good, 很 inspiring。
就是不照照镜子看看自己做了什么的一群庸人。 和十几岁的少女比比, 自己又做过什么? 有什么资格,有什么脸去毒舌人家一个女孩子。
采访到了吗? 能看看采访内容吗? 太牛了!
学生罢课让更多的人关注环保问题本身吗?很多时候这种bs leadership就是害人,也让更多人反而站对立面。
还是应该更多的支持像lz贴的这个男孩儿这类真正做事情的人。
唤起全球对环保议题的关注。 就这一点, 就比你一个成年人键盘侠强! 比你强,你总承认吧? 你十六岁时对环保做过什么?
环保少女恰恰是已经太多了的批评者的一员 ---发自Huaren 官方 iOS APP
做的比你如何? 比你16岁时如何? 你说说你16岁时,为宣传全球环保做过什么?
全世界应该更关注未成年残障人士的心理健康 ---发自Huaren 官方 iOS APP
人家说的是批评环境保护人士的太多吧。。。比较合适的说法应该是shoot the messenger
楼主说的那个男孩几年前最初提出这个idea的时候,不说别的地方,就是在华人,也是一群大妈在贬低,在否定! 当大家没印象吗?
再说,你怎么知道人家少女以后就不会实践? 你怎么知道人家就不付诸实践,不能设计出比男孩更实用的?那个男孩最初也是环保呼吁者,然后行动派。
这个世界的成年庸人就不要给自己找借口了, 太丢人了。。。。。。。。
这儿没谁是神,某一点不如别人的人多了去了。。。比如,那女孩,她的瑞典语肯定比我强。。。 但那又如何呢?
非要揪着一点说“就这一点,比你强”,这就有点偏执了。。。
以一种极傻逼的形式,让我这样的无立场人士开始讨厌所谓环保者。
明明是大妈们揪着人家小姑娘的辫子不放手。 还好意思说别人偏执。
我还觉得你更傻逼呢。。。。。 这怎么说?
是 2015 年的 FLL robotics project 里的一部分,当年的主题是 Trash Trek 环保和垃圾处理, 很多 teams 都有采访环保红人, 主要都是现场的 presentation,没啥资料保留下来的。
大妈们干啥管我何事?
您的意思是只要有人比您更偏执,我就不能根据事实说您偏执了?这逻辑好怪哦。。。比如,要说某人邪恶,是不是也可以反驳说“希特勒更邪恶,还好意思说别人邪恶?”
您两位的说法都有道理。。。

其实这些都无所谓,这归根到底还是钱的问题。
任何实质性的改善环境的操作,都涉及到大量的金钱投入。没有足够的利益的话,谁会投入这么多钱做这事呢? 如果涉及了足够利益,自然就有人做。
敢打赌16岁时候制造的垃圾肯定比不上这位16岁的女孩儿多。
那个时候大部分16岁的孩子,没坐过飞机的才是大多数,火车坐过的次数也有限,走哪儿大部分都是走路/骑自行车/坐公交,没制造电子垃圾。。。
这种东西,如果破裂,然后被水流带到近海,是不是直接可以灭掉不少鱼群???
鼓励动手,鼓励行动,但行动还是要考虑后果!
我曾经养过一堆e.coli,它们带了同一种酶,但氨基酸链略有不同,这种酶可以分解某种特殊的很难用的氮源,让细菌利用。当时养了好几天,我快放弃了,以为它们活不下来,几天以后竟然有一部分最终把那种氮源给用了,越长越好,不过速度还是不太快,比一般e.coli长得慢多了。
有没有能分解塑料更快的细菌呢,科学家们有没有办法多筛选?
至于人类,要靠法律管制减少污染,自从塑料袋收费以后,大部分人都少用了很多塑料袋,类似法律需要更多。
我16岁的时候 骑自行车上学 出远点的门都是坐大巴或火车 喝水都是用自己的水壶 从来不喝瓶装水 家里也是省水节电 做到人走灯灭 就这几点 瑞典少女自己都做不到吧 你看看她自己出行别人拍下的照片
也比自家用天量的水和电的前环保斗士戈尔强吧
我没有所谓的宣传全球环保 可是我身体力行啊
罢课的idea,能设计出什么实用的方法?

什么氮源啊?不过塑料一般里面没氮,碳倒是挺多的,什么聚氯乙烯啥的
是啊, 为什么这样的发明华人孩子做不出来
世界不缺环保意识,缺的是为了环境肯牺牲自己方便的人。
嗯,没写清楚,我就是联想了下我以前做的,觉得是不是多筛一些细菌,多养一段时间,是不是可以找到吃塑料的细菌或者分解塑料的酶。不过就算实验室找到了,离应用也还挺远的。

这个小孩的发明当然很好,但如果不多宣传,让更多人来用,或者甚至让政府强制使用,又能改变多少海洋呢?世界上当然需要埋头苦干的人才,但能组织号召的人才也很重要啊!arguably可能更重要。
哪里的世界啊?
你活在哪个地球?
