i think the circle of life simply means how life ussually goes. you are born, you grow up, have your own kids, die, and they continue there own lives. no matter the different methods used to achieve whatever you want its the same old story, from congratulations to R.I.P, but the family tree never stops growing. this occurs for all animals, all humans, all plant, all fishes, and all birds, in relation to one another, in other to keep every thing balanced.
