Based on this document, why was Harriet Beecher Stowe concerned about slavery?

Harriet Beecher Stowe was an American writer and social activist, known mainly for writing the novel Uncle Tom's Cabin. She was the daughter of a Congregationalist pastor born in Hartford, Connecticut. From 1832 she worked as a teacher in Cincinnati. Observing slave life in Kentucky (near home) and the abolitionist sentiment at the seminary where she studied had a significant impact on her, in addition to the abolitionist ideals that were defended by her father and the religion she professed. In 1850 she moved to Maine, where she wrote Uncle Tom's Cabin, a novel about the fate of a noble and heroic African American slave, Uncle Tom, which contributed to the growth of abolitionist ideas in the United States.

hello there!

the graphics that you have attached within the question, indicates that few people in bolivia work in industry according to its labor force.

however, the graphic that is on the right side of the picture shows the gdp sector in bolivia. this gross domestic product is a macroeconomic magnitude   that shows the monetary value of all finished goods and services within a country's borders in a specific time period. in this case, the graphic is showing the monetary value in each sector -agriculture, industry and services- of bolivia in 2012.

so, although the first graphic located at the left side indicates that not so many people work in industry, this is the second most important sector according to the gdp metrics because of the monetary value that impacts on its country. it does not need to be the most valuable one. if it makes an impact on the country's economy, it will be definitely crucial to it.
