Maybe I'm a dreamer, but I think the ordinary guy has just as much right to say 'This is a good song' as somebody who is in the music business.
Taking care of our planet is like taking care of our houses. Since we human beings come from Nature, there is no point in our going against nature, which is why I say the environment is not a matter of religion or ethics or morality. These are luxuries, since we can survive without them. But we will not survive if we continue to go against nature.
