Arizona and Sonora share the same ecosystem, the Sonoran Desert region. They share common history, several Native American tribes on both sides of the border, and they have six border twin towns. The natural boundary is 361 miles long and it has never been a totally closed border. Arizona needed Sonora's miners and ranchers and they have been the biggest source of migrants to the USA.
Because of the constant flow of people across the border, the Arizona-Sonora region <em>developed its own separate identity.</em> Many people living there are bilingual and commute daily to the other side of the border for work. Their value system has been affected by the proximity of a different culture. As a result of that, intercultural and interracial mixing took place that created a generation of people who feel a connection to both countries at the same time. Prejudices have been reduced and stereotypes abolished.
<em>The interdependence</em> between the USA and Mexico has always been and still is business related. Starting with vegetables trading, the cross border shopping and manufacturing developed into big industry today. A major economy connection has developed through the maquiladora sector. Arizona based companies operate about 30% of maquiladoras in Sonora and Sonora's economy is dependent on this and the automobile industry in Arizona.
Cross-border shopping, tourism ( for pleasure and medical reasons), joined environmental projects, bilingual schools and cultural events are all parts of the interdependence between the two countries.
As for the rivers, the colonists were aware you must have water to successfully maintain life whether it be human life or plant life, it is necessary. Also being close to water helped them in the workforce, like carrying out trade or fishing It was a "win win" for them.
One of the major ways in which the European Union affects the rest of the world is that it allows for expedited trade to take place between European nations, which brings down the price of various products, which subsequently helps the world economy grow.
Hello princess. So to know why the Athens and Sparta went to war, you need to dive deeper into their history. As you can tell, the Athens had a more open city, to the imagination and new ideas, while Sparta thought that they should shield themselves from anything and everything but their little towns that were inside the walls. Slave revolt caused Sparta to change how they acted because of how bad it was and how many lives were lost. The Athens and Sparta eventually had a war is 431-404 B.C.E. that caused famine, death, plague, and misfortune. Now the reason Athens and Sparta had a war was that of a rivalry on how a town or city should be run and as each of the two cities was growing stronger and stronger by day. Sparta emerged victorious of this war and has a great story to tell in the history books. Hope this helped, if you have any questions, please ask!
