You're wrong OP, nature is beautiful and free because it's a gift. That's why it's called the present. If you believe in God then you can devote yourself to improving your life and that of others but without God life is meaningless.

So many people drink or do drugs because they feel unworthy of God's love. They feel God doesn't love them and they don't love themselves. Realising that one must love one self first and foremost is a key to happiness. Not service, for without love service is pointless without compensation.
