I think the life doesn't have rank.

Every life are all the same.

The animal all eat each other.

I don't think we give the animal the chance to alife.

We eat them just because we want to.

My opinion is like Food chain .

We eat the other animal ,and the other animal eat the others .

Eat and give birth and eat.....

Because the Food chain we create the world.

So we didn't control the world.

It's the world control us.

I try to find the same opinion like me .

I find this web page.
