No food/environmental securities

After reading the articles from the declaration of Human rights, i realized that there was not one mention of food or environmental securities. All of the rights refer to the securities that concern community, health, personal and politics. I did some research on the official UN website and found alot of things. There really is no exact answer to why the declaration excludes food and environmental securities but i have come up with one. The United Nations states that they help with every kind of issue but when it was founded in 1945 it was more designed to deal with genocides and the outbreak of war. The food were probably the last thing that they needed to worry about because they may have assumed that countries could help one another provide each other with food. When it comes to the environment that is a different story. Nobody can control or change the way the environment is set up. That is why i think the UN excluded food and environmental securities.
