Well, I don't think the Vedas need be followed by all the world. Different people can follow their own scriptures.
But the Yamas and Niyamas (restraints and observances) are found in the Vedas.
Chief among these is ahimsa, meaning non-violence, in thought, word and deed.
Also featured are satya (truthfulness), brahmacharya (continence), asteya (non-stealing), mitahara (non-excess in food), shaucha (cleanliness), tapas (discipline), ishvarapranidhana (surrender of the self to the Lord), santosha (contentment and acceptance) and kshama (patience).
There's a decent ten.
