Americans began to rethink the nation's environmental policies partly as a result of the oil embargo.
When the members of the Organization of Arab Petroleum Exporting Countries, led by Saudi Arabia, declared an oil embargo in October 1973, the 1973 oil crisis—also known as the first oil crisis—began. Targets of the embargo were countries that had backed Israel during the Yom Kippur War. Moreover, they also imposed an embargo on the US in retaliation for its decision to resupply the Israeli military and to use this as leverage in the peace talks following the war.

Social comparison allows to know that the individual tends to self-evaluate, that is, to know if their opinions, attitudes and qualities are correct or comparable with those of other individuals in their environment. Ethan came to that conclusion after doing a rigorous self-evaluation of himself from the comparison with his friend.
