How was the French and Indian war caused by European expansion and competition on a global scale?

The French and Indian War was waged between Britain and France in their various colonies in North America. Both countries were attempting to expand their territories by annexing areas belonging to their rivals.
In North America, disputes emanated from the control of the Ohio River and surrounding lands. The disputes eventually escalated to armed conflicts between the British and French forces. The French had fewer people settled in North America and relied on Native Indian populations to support their attacks and defenses against the British colonists.
At the end of the war, Britain managed to gain control of French Canada and Acadia. The British deported the Acadians to create room for their immigrants. Some Indian populations were also displaced by the war. The war granted Britain additional territories, which were earlier in the hands of the French.
