mercator and peters maps

Today in Human Geo we talked about the maps and what the different types mean. There is a map called The Peters Projection Map and The Mercator Projection Map. Schools have used the Mercator Map for a long time but in reality, it is less accurate than the Peters Projection Map. The Mercator Map has had bias measurements of the countries because the Europeans created it originally to make traveling easy for them. Which caused European countries and the United States to appear larger than some of the 3rd world countries, even though its not actually the correct size. I find this interesting because its weird how I have been learning the sizes of countries wrong this whole time and had no idea.
