Since polystyrene disintegrates slowly, one of the main challenges that it poses on the environment is that exposure to the sun causes it to photodegrade, meaning it breaks apart into smaller and smaller pieces. The broken down material ends up looking like food to small animals.
United States Congress elections, 2016. A total of 469 seats in the U.S. Congress (34 Senate seats and all 435 House seats) were up for election on November 8, 2016. The big story of the 2016 congressional election cycle was whether or not the Democratic Party would be able to regain control of the Senate.
Each member of the US House of Representatives is elected by the voters of his or her Congressional District within the state he or she serves. Representatives serve a two-year term of office, and all 435 seats come up for election at once, in even-numbered years. A Congressional District is a geographic area within a state.
