Let me handle your first question -- always good to do one question at a time here. :-)
Prior to President Theodore Roosevelt, those who preceded him in federal government had tended to side with industry leaders, expecting laborers to fall in line and do the work for the good of the companies. In 1902, when there was a particularly tense strike by coal workers, Roosevelt invited both sides (labor leaders and management leaders) to the White House to negotiate. This was an example of the way he saw the role of government leadership as "steward" to the nation, mediating on behalf of everyone's interests, not just the interests of a powerful small group. His "Square Deal" policies were aimed at making things fair and square for the general public. An example of this would be how much land was set aside under his administration as national forests, national parks, national monuments, etc. He was seeking to protect the use of the land for all Americans' interests, rather than letting corporations tear into any land or forest they wanted in order to grab natural resources.
Answer: When the Panama Canal was created by the U.S. government between 1904 and 1914, they decided to build a lock canal. And that meant that, in effect, every ship that passes through the Panama Canal goes up effectively three steps to 85 feet above sea level. There’s a large dam that blocked the original flow of the Chagres River towards the Caribbean, and then water flows through the locks with the ships. So it’s a massive lake that was created primarily to move ships through the oceans, but when they did that, of course they flooded the entire region. So the entire Chagres River valley, which was a place where there were many small Panamanian communities, was flooded. And a lot of the kind of natural history of the region was lost in the flooding of the canal as well.
