Your ancestors went for diversification. Just like a good fund manager they got you a lot of everything. An ocean so you can fish in, rivers so you can drink and water your gardens, dry mountains so you can gain your stones, emeralds, cement and limestones to build, tropical landscape so you can grow your bananas and tomatos, lots of land so you can graze your lifestock, and far borders. Its akin the diversification of terrain the U.S responsible for its success. But like ungrateful children of the wealthy forever spolit, lazy and entitled we chose to squander instead of build on their success.
