Yes, it is grammatically correct. However, you could make a few changes. 1.The tone of the sentence is rather formal, and "has to" is informal. A word that means the exact same thing but is more formal is "must". 2. I'm not sure why, but when talking about amounts of things, like money, we never say "bigger." We say "larger". Society must invest larger amounts of money in educating children to be more responsible with the environment.
