It has been estimated that just one of these container ships, the length of around six football pitches, can produce the same amount of pollution as 50 million cars. The emissions from 15 of these mega-ships match those from all the cars in the world.
Which is of course a shit ton of emissions, but 15x50 million is 750 mln, and isn’t there like 1.5 bn actively driven cars? The math kinda doesn’t check out.
P.S. And again Americans with their football fields per furlong :) Why not at least mention something in actual units? I have no idea how big a football pitch is.
