What was the primary focus of Cesar Chavez's activism?

Cesar Chavez's activism was primarily focused on advocating for the rights and welfare of farm workers, particularly those of Hispanic descent, which encompasses issues related to labor conditions and civil rights. He co-founded the United Farm Workers (UFW), which aimed to improve the working conditions, wages, and rights of agricultural laborers. Chavez led nonviolent protests, strikes, and boycotts to bring attention to the challenges faced by farm workers, such as long hours, low pay, and unsafe working conditions. His efforts played a vital role in raising awareness about labor rights and establishing unions for farm workers, further highlighting the intersection of civil rights with labor issues, particularly for the Hispanic community.

While the other options touch on important topics—such as environmental protection, educational reform, and political representation—they do not capture the core of Chavez's work, which was specifically aimed at improving labor conditions and advocating for the civil rights of farm workers.
