Which career would be right for me?

ever since I was small I want to bring a huge change to the world. I want to engage in philanthropy, help the poor, stop the widespread extermination of animals and things of that sort. As I grew I found that nothing can be done, if one does not have money. So I decided that keeping these aims in mind, I want to become rich enough so I can really help people in the world. But I want to become rich in a way that it does not further harm the environment (that would be quite ironic if i did). So I'm good at music and writing, but those will not make me rich for sure. I was looking for something maybe related to politics or business that would help me become rich to help people, but at the same time people only pay attention to those that make headlines, so I would like to make papers so that people join me in my cause. What career would be right for me?
