What social and political challenges did americans face in the 1960s and 1970s?

The 1960s were a decade of intense political activism . One big issue was the Civil Rights movement that demanded equal rights for African-Americans. Another great issue was the peace movement that opposed the US involvement in the Vietnam War.

The 1970s witnessed the continuous civil fight of African-Americans, Native- Americans, women, guys and lesbians for their rights and causes. In 1972-1974, American society was shaken by the Watergate scandal that led to the resignation of president Richard Nixon who abused his power by ordering to spy on his political rivals and by obstructing justice. The Watergate issue strengthened freedom of the press and the role of the press as a watchdog of power.

Explanation:

the underground railroad (apocope of the metropolitan railroad) is a system of urban trains located within a city and its metropolitan area. it is characterized for being a massive transport of passengers in the big cities, uniting diverse zones and their environs, with high capacity and frequency and in segregated form to other systems of transport. metropolitan railroads are built underground or on the surface, although most systems use mixed models where sections are combined in both modalities.

1 - as a result, the metro tends to reduce car travel for two reasons: first, due to the greater transfer of users from the car and, second, due to the reduction in the acquisition of cars in homes located in sectors near the stations of the metro.

2 -the metro allows to contribute effectively to the achievement of all the objectives of an urban development policy: it improves the efficiency of the city's economy by reducing travel costs and also generates a higher level of activities in the city center, taking advantage of of the agglomeration economies.

3 -it is a clean means of transport, since it uses renewable energy (usually electricity), taking care of the environment and avoiding excessive pollution.
