In many National Geographic programs I watch, carnivores kill and eat herbivores and sometimes steal other carnivores' prey. Although eating another animal while it is still alive (in one of the documentaries hyenas started eating a buffalo's behind while it was still alive) seems very cruel with my human eyes, that's how nature works. Carnivores have to eat other animals to survive, they can't eat grass.
On the bicentennial of Darwin's birth, we should reconsider telling childrens' stories that present carnivores as bad guys who eat the good guys. This stupid personification turns children judgemental, where no judgement needs to be applied. Wild animals just do what millions of years of evolution programmed them.
The birds on the treetop are programmed to soil my car parked underneath . Luckily cows can't fly.
