At least 3 millennium development goals

The millennium goals for the UN are:
- Reduce the spreading of HIV/AIDS 
- Eradicate extreme hunger and poverty
- Improve maternal health
- Reduce child mortality
- Global partnership for development
- Gender equality
- Environmental stability.

You can choose out of these; these are all the millennium goals
