Butterflies In The Amazon - This (along with so many innumerable reasons) is why the rain forests are so important. We are destroying so much of our world that we could lose things like this in our lifetime. That's too fast for the Earth to compensate.
Butterfly's are so important to the human race, if we never had butterfly's and bees there would be no such thing as planet earth. So if you see a bee or butterfly please do not kill it or spray it with bug spray.
