and I have no idea why

但又不知道为什么要带
because I'm not particularly dehydrated.

因为我并没有特别的脱水症状
But people think they need to have water with them all the time.

而人们认为他们确实要时时刻刻都带着水
And if I think back to my own childhood again,

如果我回忆一下自己的童年
not that that was the glory days by any means,

不是说我的童年有多光辉灿烂
but I mean people weren't falling over hour after hour from dehydration

而是我想说当时人们也没有因脱水而倒下
because they didn't have a water bottle with them.

而因为他们没有随身携带水壶
But we've been so completely socialized into thinking two things:

但如今我们都对以下两个观念习以为常了
one is that we need water with us all the time;

第一是我们每时每刻都需要水
and second we have to buy it.

第二是我们要花钱买水
That creates all sorts of social consequences

这就产生了很多社会问题
that we'll talk about sustainability,

比如我们将要谈到的饮水污染问题
