Impact investing

I’m writing an article about impact investing/socially responsible investing/socially conscious investing. Here’s what I’d like to know:
1. What is the best way to use your investment dollars to make a positive difference in the world?
2. Will you have to sacrifice returns to pursue your values with your investment dollars? Why or why not?
3. Is it possible to be a passive, socially conscious investor?
4. Do you have any advice for choosing a socially responsible fund?Requirements: Seeking responses from financial professionals who do not work for a MassMutual competitor and who have a clean regulatory history.
