Arne Næss was one of them how made the word Deep Ecology. In his life he tried to get people to understand that we can kill for survive but we have to be careful so we dont overhunt.
Thats one of the problem in some lands as Africa where the elephants are starting to get extinction.
And in Japan you get killed for trying to kill a panda because they are in a so small number.
Arne Næss also think thout that you dont have to cut done to muck of the woods to. So this two text are very much alike the other one.
So in all Arne Næss have right because we dont need to take more than we need then many animals gonna go lost.
