" Plastic bags were created to save the planet, inventor’s son says ‘To my dad, the idea that people would simply throw these away would be bizarre,’ claims Raoul Thulin https://www.independent.co.uk/environment/plastic-bags-pollution-paper-cotton-tote-bags-environment-a9159731.html Plastic bags were invented to save the planet, according to the son of Swedish engineer Sten Gustaf Thulin who created them in 1959.

电瓶车啊猫啊狗都能造。既没有发动机，也没有变速箱。和内燃机的精致工艺不沾边。从蔚来买个锂电池，罩个壳子就走了。可这锂电池的技术瓶颈使电瓶车只能城市代步。环保人士所谓电瓶车环保也是个假命题。别说中国，就是美国，60％以上的能源也是化石能源。把化石能源先转化成电能，再转化成化学能储存在电池里。再转化成机械能驱动电瓶车。初中学过能源转换吧？效率有多高清楚吧？三次能源转换得浪费多少能源？为何不让化石能源一次转化成热能驱动内燃机？这还不说电池分解的污染。电瓶车环保？扯啦。
