The comparison is IMHO misleading because the tree seedlings/growing trees are still natural organic matter. Water is of natural origin and part of the hydrological cycle, regardless if it forms a sea, a lake or is stored in a reservoir.

In contrast the mining faces exist not by geological consent, they are artificial.
