 There's now proof that social media activism actually works. The ALS Ice Bucket Challenge that swept the U.S. in 2014 did a lot more than just get your clothes soaking wet. The viral challenge raised $2.2 million. The money funded the development and trial of a new drug that was recently approved by the FDA to help treat ALS and slow down its effects. While the Ice Bucket Challenge paid off big in the end, people should always be on the lookout for ways they can give back without waiting for the next big thing.
