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

This is all you, but i can give you some topics that you could try. if it rained when you want to do something outdoors, it 'limits' that human activity. maybe you want to do an experiment that goes throughout the whole year and you have to have above freezing the entire year. this 'limits' your activity. i thought of those just off of the top of my head. something that gets to me that might be getting to you is you are thinking too hard about what to do. think simply, and if it is too simple, then bump it up just a little bit.
