This earth was formed and then life began. All kinds of life. Plants, insects, birds, mammals, reptiles, and so on... We can agree with that part, I am pretty sure.

Evolution of the species occurred and certain species obtained dominant mentalities. Humans for one, decided they wanted, they desired, they needed. So they took what they wanted.

At first they hurt other beings feelings, and those hurt beings dared to share their unhappiness. They displayed their unhappiness and did their best to display evidence of the eternal error of man's ways. With a fight, they gained their rights and freedoms back, that had been stolen away from them. So they became dominant in defending what they felt needed protecting.

There are dominant animals and there are meek animals. The meek animals are still victims of the dominant beings. The meek are basically gentle and mean no harm to others. The dominant see the meek as beings and "things" to use for their own needs and wants. So the dominant slyly find a way to steal the life of the meek away from them, feeling they have no rights living unless they say so.

The dominant beings feel they have to do this to the weak meek beings cause it makes their own lives better and stronger. They don't want to find another way, cause they don't really care about the meek beings life. They care about themselves.

So in short, yes all animals have the right to live on our Earth, they have a right to breath, eat, procreate, and just be. They started out in the same way as all beings have. We are all equal.

It is in the pleasure the dominant beings get from using the meek that keeps them being dominant instead of harmonious. They have gone from having a right for survival, to believing they have a right to take over. Just cause the dominant take over the planet, doesn't mean the meek beings are not their equals. It means simply they have very little respect for the other beings on this planet.
