Really good points here. No denying this is just another way to donate money to an NGO who is trying to make things better. Also no denying that this is not the silver bullet that will fix a big sticky problem. However, I think the point of campaigns like this isn't to solve something, but to bring awareness to a problem. If we can make a tool that helps an issue click in enough peoples heads, then a campaign is successful. Then in theory, if enough people care then momentum will build and enough attention will be given to the issue and steps will be taken toward making it better. This is a long and laborious process. Sanitation and hygiene is an incredibly complicated system that involves governments and lots of money (that people just don’t have), and a lot of creativity.
All that to say, I don’t know why things aren’t better. All I know is that if I can make something as a designer that gets people thinking about an issue for a few minutes more than they did before, then I’ll do it.
