Why doe snowball throw ribbon into the fire?

In George Orwell's "Animal Farm," Snowball throws the ribbons into the fire as a symbolic act to reject human symbols of oppression and luxury. The ribbons, once a sign of the animals' servitude to humans, represent the ties to their former lives and the bourgeois values associated with them. By discarding the ribbons, Snowball aims to promote the idea of equality and to encourage the animals to embrace their new identity free from human influence. This act underscores the revolutionary spirit of the animals and their desire to establish a society based on their own principles.
