Explanation:

The battle of Lexington and Concord represent the first shots fired in the American Revolutionary War, on April 19, 1775, near Boston. On April 14, 1775, the British army in Boston received secret orders to stop the “open rebellion” in Massachusetts. General Gage decided to arrest rebel leaders and seize the militia’s gunpowder stored at Concord, about twenty miles northwest of Boston. Some seven hundred redcoats marched to Lexington just to find Captain John Parker evoking a minutemen rebellion. When the British soldiers decided to get into the road to Concord the Americans decided to stop their advance. The Americans inflicted fourteen casualties, and by noon the British had begun a ragged retreat back to Lexington, where they were joined by reinforcements. By then, however, the narrow road back to Boston had turned into a gauntlet of death as hundreds of rebels fired from behind stone walls, trees, barns, and houses, approximately 100 Minutemen and 250 British soldiers were killed.

The 2016 Olympics organizers tried to minimize the impact of the event on the environment.  Some examples of their sustainable practices are:  plant 24 million seedlings to reduce or offset the carbon emissions caused by the Games.  The Olympic medals usually made out of bronze and silver incorporated recycled material.  They also intended to fix or upgrade the sewer system to reduce the level of pollution in the Guanabara Bay.
