The environmental movement (sometimes referred to as the ecology movement), also including conservation and green politics, is a diverse scientific, social, and political movement for addressing environmental issues.
U.S. Entry into World War I, 1917. 1  On April 2, 1917, President Woodrow Wilson went before a joint session of Congress to request a declaration of war against Germany.
So, what did all this have to do with America and why did we enter World War One? Most Americans favored staying out of the conflict and President Wilson publicly and formally stated that the United States would follow a policy of neutrality. In three short years, however, the United States would find itself in the middle of what later became known as the first World War. As the war in Europe raged on America sympathies were clearly on the side of the allies. American propaganda posters urged citizens to buy war bonds and support the allies.
