enviornment and food

The United Nations did not put anything that relates to the enviornment and food in the Human Right's, because it's common sense. Everyone knows that they're entitled to the right of food and the enviornment because we breathe. Air is free you dont need to put that in the 30 rights that everyone has, because the people already know this. Food is essencal for humans to live, you need it and everybody knows that or everyone would be dead.
