Do boycotts work in the modern world? give relevant situations

Yes boycotts work, back in the day African Americans boycotted sitting in the back of the bus. It worked. They boycotted by not giving up their seats to whites.Many got in jail for that, but that is the point of boycott. Boycott is when you protest something you don't believe is right. Another boycott is native american pipelines. Native Americas protested putting a pipeline that would pollute their river water they drink from, as well as putting through their burial grounds. But the Natives protest didn't work. While the Bus protest did. Sometimes it just depends on the situation.
