The explosion of the USS Maine and the practice of yellow journalism played a significant role in the 1. public's support for the Spanish-American War. The USS Maine was stationed outside of Havana, Cuba (then a colony of Spain). Its explosion was widely (and most likely incorrectly) attributed to Spanish tampering and thus was used as a reason to declare war. Yellow journalism spread these messages to the public who widely believed the insidious nature of the Spanish illustrated by this journalism.

These islands/chinampas then provided rich soil for crops with easy access to water. i hope this is correct, im so sorry if its not !
