Stalactites form as trickling water deposits tiny quantities of rock over hundreds or thousands of years.

含有微量岩石沉积物的水流经过千万年时间形成了钟乳石。

Since trickling water, hungry caterpillars and suffering plants are all very quiet, it seems worth investigating whether plants face similar problems.

由于滴水、饥饿的毛毛虫和受苦的植物都非常安静，因此似乎值得研究植物是否面临类似的问题。
