Leonardo DiCaprio is better remembered by everyone as Jack because it was the film which took him to the heights of glory. Even though, he became the king of all hearts by acting in this all the time hit movie, the journey of this wonderful actor didn't start from this movie.

He is not only an actor, but also an active environmental activist. He believes that everyone should be aware of the responsibility we owe to this mother earth. He further goes on to say that since he resides in the US, the most developed country in the world, he wishes to do something to prevent environmental pollution.
