The competition for power and wealth of the European nations between the 16th and the 18th centuries contributed to big changes in the geography of the world, both the knowledge of it, and the change of the landscape as well.
The European nations in attempt to become stronger and richer, managed to discover many new places around the world, that were totally unknown in the so called ''Old World''. The discoveries of the Americas, Australia, Antarctica, and thousands of islands across the world, significantly changed the way the world was seen until then. There were suddenly multiple other continents, lots of new things were discovered on them, and the maps changed pretty much on a yearly level.
Also, as the European nations were managing to get hold onto the new lands, they started to farm large portions of land, mostly with cash crops. That practice contributed to the change of the geography on regional level, were lots of swaps, marshes, small lakes, were drained, river flows relocated, forests cleared, grasslands replaced, so the landscape in a very short period of time changed totally.
