文章第二段：

The benefits many found heartening early on--from cleaner air to birdsong newly audible as cars and planes went quiet-were always likely to be temporary. And with lockdowns easing, they have already begun to dissipate.

疫情對環境帶來的益處很有可能只是暫時的(temperary)，而當封城狀態結束後，這些益處就會開始逐漸消失(dissipate)

所以這裡的they是指benefits（疫情對環境帶來的益處）
