Only humans can define rights and humans decide the rights of animals. Humans generally prefer the rights of humans above animals. When defining the right in the question, we generally refer to humanity's right here, not animals.
Animals can exercise the right of being free, having food, water and other resources. Just because they would not understand that they have a right to it, wouldn't make it fair to take it away from them.
"Only if animals are considered to be people" Who established the rule that they have to be considered people? You set up this rule yourself. If we ruled that animals have a right to earth resources, we would have to share it with every other animal (because we are animals ourself too).
The point I was referring to, as stated in my last question, was what legitimates that humans have right to earth but animals don't. If I made this question is because I undestood what you stated, or I woudn't have asked "..resources should be divided only among humans?".
But all jobs aren't equal. Why should a person who spent 30 years of his life training to become a doctor get the same things that a person who heats food in microwaves does. This will greatly reduce the incentive to do risky, unwanted, and hard jobs
If that were the case that everything was equally distributed. Society would stand still. No body would get fairly rewarded for their efforts, whether their efforts were big or small. You could be an architect or a street sweeper get the same amount of "riches".
Biologically we are all made to live off of the earth. It's essential to our good health. A scientific analysis would say living w/ out access to earth's riches depletes health; therefore the law should consider it a right. We've already made progress towards this point w/ access to clean air.

The definition of earth's riches needs to be defined. Water, of course, and vegetables, but animals? Trees and plants? Do people living in the desert have the right to live somewhere where they can grow crops? Who implements this? All these and more are tough questions.
We can possibly nullify this problem by granting everyone access to the earth's riches produced in their city, state, region, or locality. It would be a tricky line drawing situation but overall, a positive move. Still though, I don't know what we can do to help those in the desert!
Put crudely, why? Rights are not universal absolutes, they are the result of societies. Rights are created when society decides upon them. Why would society want to reward everyone equally, when not everyone contributes equally to society?
