The United States imports the most oil per day! They import over 10 billion barrels per day. The United States imports oil from Canada, Saudi Arabia, Mexico, Russia, and Venezuela!
England was pretty much broke after the French and Indian War, and to start getting money and paying back debts, they started taxing the American colonies. Some of the specific things they taxed were tea (which led to the Boston Tea Party), stamps, glass, lead, and paints that were imported into the colonies. All these taxes fell under the Townshend Acts.
I'm not sure on the context of your question, but the Europeans were looking for a faster way to India and discovered the Americas by accident.
In 1773 the British parliment passed the Tea Act. The Tea Act was designed to help the East India Company which was in financial trouble. Most tea at this time over 80 per cent was smuggled tea from the Dutch. Parliment allowed the East India Company to import and export tea tax free in England but imposed a tea tax on the colonists. Colonists objected to this new tax as the price of tea went up. One result was the Boston Tea Party where colonists dressed as indians in Boston boarded and English ship and dumped the cargo of tea overboard.
Farming is the correct answer to this problem.
