During the late 19th century many environmental problems caused changes and created public awareness. One problem was that the country could soon run out of vital natural resources like wood. This led many people to join the “conservation movement” in the early 20th century in order for future generations to have enough supplies that were made from raw materials. Another problem was the fate of the “wilderness”, so many organizations began to fight for undeveloped lands should be preserved. Lastly, one big problem was pollution. This issue was a big threat to the fast-growing cities, which led to efforts in order to improve the urban environment. There were also some changes and the popular sports. During the late 19th century the Olympic started to become an international spectacle. Apart from that there were also many games like baseball that started to grow in popularity. Due to many segregational beliefs during this time there were many only African American teams that were created.
One last thing that changed during the nineteenth and twentieth century was the art of the United States. Abstract expressionist movements started after World War II. Later came minimalism and pop art.
Popular Sports and Art weren't as culturally prominent until the 1920s. Environmental Protection started around the second Industrial Revolution because factories were using way too many resources. Environmentalists wanted to make sure future generations had natural resources to exhaust too. Theodore Roosevelt made regulations forbidding hunting of endangered animals and tree planting programs to make sure we would have a fresh cycle of lumber instead of waiting fifty years for wood to grow.
In 1788, in the 78th paper of “The Federalist, Alexander Hamilton argued for judicial review by an independent judiciary as a necessary means to void all governmental actions contrary to the Constitution. Marbury v. Madison 1803. Was an early Supreme Court case that affirmed the Court's power of judicial review by striking down a law made by Congress as unconstitutional. In his written opinion, Chief Justice John Marshall declared that “an act of the legislature repugnant to the Constitution is void.”
