And speaking of trees ...

A tree can grow a maximum of 130 m tall. The laws of physics set a limit to the growth: Gravity affects the water, as it rises through the trunk, and sooner or later, the tree will be so tall that gravity wins. The world's tallest tree species is redwood, which can grow up up to some 115 m high. The lowest tree species, dwarf willow, only rises 6 cm into the air.

On a hot summer's day,

approximately 1,500 litres of water evaporate from a large oak, corresponding to about 11 bathtubs.
