In her passionate speech, she said, "I am from Britain and I think it is right that I am paid the same as my male counterparts. I think it is right that I should be able to make decisions about my own body. I think it is right that women be involved on my behalf in the policies and the decisions that affect my life. I think it is right that socially, I am afforded the same respect as men."
For the doubters wondering why she was there, she says, "You might think: who is this Harry Potter girl? What is she doing at the UN? And it's a really good question—I've been asking myself at the same thing. All I know is that I care about this problem and I want to make it better. And having seen what I've seen and given the chance, I feel my responsibility to say something."
Not only was Watson there for a cause she believes in, but DiCaprio is now the new UN Messenger of Peace. The actor is an environmentalist and Ban Ki-Moon himself said after presenting him the honor that DiCaprio is "the new voice for climate advocacy."
