Back in the old days, I mean the way-back old days, societies were centered around the source of food. This was true in hunter gatherer societies as well as agricultural societies. The main difference was that in the former, the food was always moving Cheap Cincinatti Bengals Jerseys. In the latter, it was in the same place. That's why societies started getting bigger and bigger once they figured out how to tap a non-moving source of food. Of course, you still had to live close to the food. Once you took it from the ground, you had to bring it to your house, or bring it somewhere to sell it. In this regard, the size of society was limited to the most efficient means of transportation. In the beginning, most cities were near waterways. That meant it was easy to transport large amounts of grain and meat. Later on, when they had fairly efficient means of ground transport, societies started to expand inward. For a long time, a horse drawn vehicles was the only way to deliver goods. And since horse drawn vehicles could only go so far, society was limited in it's size Cheap Jerseys. There was very little trade that took place across long distances. The further away you were from a source of goods, the less likely they were to be food. The railroad changed all this. This could go long distances for relatively cheap. Now people could enjoy fine food from far away places nfl Jerseys. This is when society really began to take off. Expanded trade meant more wealth for everybody. More wealth meant more people could buy more stuff. It was a wealth generating loop that fed on itself. Then the automobile was created. After several decades of refinement and improvements, big trucks could drive goods places where even trains couldn't go before. Sometimes trucks would drive goods straight from the factory or farm to the store that sold them Cheap Bears Jersey. Sometimes they used trains in between. With the massive expansion of the national highway system in the fifties and sixties, more people all across the country had access to goods from pretty much anywhere in the world. It was not uncommon to eat eggs from Brazil, bread from France, and sugar from Cuba. It was a truly golden age. What made it even better was the invention of refrigerated transport. There are always some goods that need to be kept cool for whatever reason Cheap Ravens Jersey. Now these items, be they food, medical supplies, or something else, they could be kept cool from the moment they were created, to the moment they were purchases by the consumer. And this is good for everybody.
