Actually, I think that it is reasonable to invest in such projects only if you believe in this industry and want to contribute in our environment. That's very noble. But the thing is that the majority of people don't care about these problems, so they would invest in such projects only in order to get profit. If you are chasing the same goal, you had better look for something another so as not to be disappointed then as I don't think that such projects will attract many investors actually.
