Right livelihood means that one should earn one's living in a righteous way and that wealth should be gained legally and peacefully. The Buddha mentions four specific activities that harm other beings and that one should avoid for this reason: 1. dealing in weapons, 2. dealing in living beings (including raising animals for slaughter as well as slave trade and prostitution), 3. working in meat production and butchery, and 4. selling intoxicants and poisons, such as alcohol and drugs. Furthermore any other occupation that would violate the principles of right speech and right action should be avoided.
