Talk:天然橡胶.
“巴西一些土著会利用橡胶制造防水布料,他们用火焰把树胶熏干并以此处理衣物好让他们在潮湿的雨林中保持身体干燥。曾有传闻称有葡萄牙人把这些衣服带回祖国,把同乡吓坏了,结果被控施行巫术而受审判。”“在亚马逊雨林的土著更直接把橡胶树汁涂抹在脚上,约略二十分钟后异戊二烯分子便和空气中的氧气作用,氧原子会连接各异戊二烯分子形成近似固体的结构,然后土著就可以穿着这种橡胶靴在雨林中活动,只不过由于氧的化学活性大,一天后这种橡胶靴就会解体[1]。”
在前面的例子中,用火焰将树胶熏干制造的防水布料不会在一天内失去布料上的橡胶吗?为什么后面的例子中这种橡胶靴会解体?是不是人为给抠下来的?当地土著真的有这样做吗?葡萄牙人将经过处理的防水衣物带回祖国,被控施行巫术这点,我觉得有些不可信,难道同乡和审判者都不看衣服上增加的物质吗?
不过从刚果等中非地方盛产的橡胶紫茉莉采收天然橡胶较为困难,采收成本相对于三叶橡胶树较高,为了维持价格上的竞争力,采取强制劳动的制度压低人工成本,发生了不少暴力、流血的人道悲剧,而因为血是红色的所以该地区当时产的橡胶俗称为“红橡胶”。
我看到配的一张图是刚果一个没有完成橡胶采收配额的父亲看着5岁女儿被砍下的手和脚,文字内容中提到强制劳动,这像是将当地人当作奴隶一样强制劳动,这种情况下,这些人是会得到报酬的吗?真的有人工成本吗?──以上未簽名的留言由蔡菲(討論|貢獻)於2021年6月20日 (日) 15:47 (UTC)加入。[回复]
