Food and Environment Rights

After reading over the 30 Articles of the Declaration of Human Rights, I was a little confused as to why Food and Environment were not mentioned. After doing a little research and thinking it over, I found out that not all of the Rights can really be controlled. Making sure that the world has enough food is not really and easy thing to keep track of, as well as making sure the environment is taken care. We have the opportunity to have these rights, but some things cannot be controlled, which is why I think that the right to Food and a healthy Environment are kind of assumed as rights, being that we are literally unable to live without food, and the Declaration did not include them because humans in the government and in society have no control over them. These rights are tangible things, unlike Politics and the Economy or a Community. The Declaration did not include Food and Environment because these two rights will not always be a problem. Lack of food is a global issue at the moment, but when the Declaration was written, it was not as big of a public issue as it is today.
