Question

Why is Animal Farm and its themes still relevant today?

Answer 1

Because the economy and most of the politics are still the same and the same treat meant for everyone
 

Answer 2

Since Animal Farm basically tells us the history of the Russian Revolution, all its themes are still relevant. It talks about the development of communism and how it is associated with corruption, control of a naive working class, deceptions, dreams, hopes, and lies. Those are topics that will never stop being relevant in the world.
