@MichaelSFuhrer You don't need to eliminate an industry for any individual to not use it! The point is that it is definitely quite feasible for an individual to reduce exposure vs average that much (and some likely do it without even trying!).
Quite different question from society overall.
@MichaelSFuhrer 您不需要消除任何个人不使用它的行业！关键是，对于个人而言，减少与平均水平相比绝对是完全可行的（有些人甚至可能没有尝试就做到了！）。
与整个社会完全不同的问题。
