Raise your children as well as you possibly can, make sure their needs are met, always be there for them, surround them with love, and they are not going to give a damn about what you did to the environment. As they grow in your presence they will learn what kind of person you are. The longer you wait to produce progeny, the harder it's going to be. If you don't produce tolerant, productive, law abiding citizens, there won't be a future.
