2、elated as we live in the same environment.Reference:A couple of odd things have happened lately.I have a log cabin in those woods of Northern Wisconsin. I built it by hand and also added a greenhouse to the front of it. It is a joy to live in. In fact, I work out of my home doing audio production an

3、d environmental work. As a tool of that trade I have a computer and a studio.I also have a tree frog that has taken up residence in my studio.How odd, I thought, last November when I first noticed him sitting atop my sound-board over my computer. I figured that he (and I say he, though I really dont

4、 have a clue if she is a he or vice versa) would be more comfortable in the greenhouse. So I put him in the greenhouse. Back he came. And stayed. After a while I got quite used to the fact that as I would check my morning email and on-line news, he would be there with me surveying the world.Tree Fro

5、g went across my view. He stopped and turned around and just sat there looking at me. Well, I sat back and looked at him. For five months now he had been riding there with me and I was suddenly overtaken by an urge to know why he was there and not in the greenhouse, where I figured hed live a happie

6、r frog life.“Why are you here,” I found myself asking him.As I looked at him, dead on, his eyes looked directly at me and I heard a tone. The tone seemed to hit me right in the center of my mind. It sounded very nearly like the same one as my computer. In that tone I could hear him “say” to me, “Bec

7、ause I want you to understand”. Yo. That was weird. “Understand what?” my mind jumped in. Then, after a moment of feeling this communication, I felt I understood why he was there. I came to understand that frogs simply want to hear other frogs and to communicate. Possibly the tone of my computer sou

8、nded to him like other tree frogs.Interesting.I kept working. I was working on a story about global climate change and had just received a fax from a friend. The fax said that the earth was warming at 1.9 degrees each decade. At that rate I knew that the maple trees that I love to tap each spring fo

9、r syrup would not survive for my children. My beautiful Wisconsin would become a prairie by the next generation.At that moment Tree Frog leaped across my foot and sat on the floor in front of my computer. He then reached up his hand to his left ear and cupped it there. He sat before the computer and

10、 reached up his right hand to his other ear. He turned his head this way and that listening to that tone. Very focused. He then began to turn a very subtle, but brilliant shade of green and leaped full force onto the computer.And then I remembered the story about the frogs that I had heard last year

11、 on public radio. It said frogs were dying around the world. It said that because frogs skin was like a lung turned inside out, their skin was being affected by pollution and global climate change. It said that frogs were being found whose skin was like paper. All dried up. It said that frogs were a

12、n “indicator species”. That frogs will die first because of the sensitivity.Then, I understood.The frogs have a message for us and it is the same message that some sober folks have had for us. “There are no more choices.” We have reached the time when we must be the adults for the planet, for the sa

13、ke of the future generations of human and for frogs.Because we are related.Then I understood that there are no boundaries, that there is no more time.That we, for the sake of our relatives, must act now.And then I understood, not only why the frog was there, but, also why I am here. Suddenly I had a

14、 strong urge to know why he was there and not in the greenhouse, where I thought hed live a happier frog life. The tone seemed to attract my intense attention. “Understand what?” the question came into my mind. The fax said that the earth is getting 1.9 degrees warmer every ten years.Ex. 2Telepathic
