Assuming rock is 2000 kg per cubic meter and the one drawn is one meter high, then that boulder weighs 1000 kg, and we can see it moves, which goes to show that stick people are VERY strong!

:Like stick people, the rock is two-dimensional. Since mass only increases with the square of the linear dimension in 2D, the rock might still be movable by a single person. That said, the force generated by what must clearly be one-dimensional muscles is harder to predict.

In addition to Paris agreement, glaciars are also quite topical because a crack in the Larsen C ice shelf is weeks away from breaking off a huge piece of Antarctica. See: Patel, Jugal K. ''A Crack in an Antarctic Ice Shelf Is 8 Miles From Creating an Iceberg the Size of Delaware''. The New York Times.
