What can i do if my father drinks a lot, which leads to family problems.. anything i can do?

Try Al-Anon(for you): There are therapist who do "interventions, " but not guaranteed & can be expensive. In truth, u can't make him stop & u can't "make him drink." but u can learn to set healthy boundaries, not enable him & take care of u, which also may help him. Support & learning skills in al-anon or other codependency groups will help. He may change as u do something different but even if not u will feel better.
