Humans need to learn that we SHARE this earth with other species. When we go walking in a wild habitat and get attacked by a wild animal, it doesn't mean we have the RIGHT to kill that animal. It is terrible a little boy was injured during a hike Picchetti Ranch Open Space Preserve in Cupertino by a Mountain Lion - but seriously, how do we expect them to behave? If they are hungry, they will go after perceived prey! Come on people - leave this animal alone!!!! It's acting according to INSTINCT!
