Human securities

I believe that all of the seven major securities are very important. In my opinion the most important one would be the Food security. Without food or water there is no way to live. I believe you can live only two days without water and about two weeks without food. There is very little time to help this problem because people will die very quickly without this. No food violates many other human securities as well including health, environmental and personal. It violates health because the people will die without food. Environmental because there is no clean water. Personal because if there is no food there is no way to stay alive.
