After 15,000 years, it's waking up

3:44 - your use of the Mercator projection is diabolically bad, I'm sad to say.
Mercator is a sailing map whose intention is to allow for navigation by sea - nothing more.
It massively deforms the sizes of land masses. It is utterly and totally inappropriate for ANY scientific use.
For example, the tiny landmass of Greenland looks the same size as South America, whereas in reality it is 1/9th the size.
Mercator despicably enlarges landmass size the further North or South you go.
And so you saying "1/5th the landmass" while showing us a Mercactor map is physically misleading. So much for physics!

If you want to refer to land area, then you should be using a Peters Projection, as this map shows every land area correctly in size! Necessarily it does deform the shape of a country or landmass, but the shape is much less important that the idea of equal-area!

I'm only giving you 6/10 for this one, because maps are very important to the way humanity views our globe - and the Mercator has warped and twisted our view of the Earth for far too long. It should NEVER have been adopted as a reference map, and its use should have been restricted to ocean navigation only.
