The Problem with Maps
The Earth is a sphere and as there is no perfect way to show the surface of a sphere on a 2D rectangle, any map will have issues.
There are many ways how a map can be devised from a spherical surface, so called projections (see Wikipedia article on Map projections).
A very popular projection is the Mercator projection, named after Flemish geographer and cartographer Gerardus Mercator, who developed it in 1569 (see Wikipedia).
The issue with the Mercator projection is that it distorts the size and shape of objects – in particular it exaggerates areas far from the equator. How strong this effect is, is illustrated by the video embedded below.
