Big Bear Hug by Nicholas Oldland
For the littlest environmentalists, a book as silly as it is big-hearted. The bear wanders all over the place hugging stuff. Animals and trees, mostly. When he comes upon a man who starts to CUT DOWN a tree, the bear briefly considers mauling him to death before reverting to his nature (!) and hugging the guy. Who runs away, extremely unnerved.
And this bear reminds me of someone... ah! the bear in Jon Agee's Milo's Hat Trick. It's the lack of mouth, I think. In the Agee title, I tend to think the bear is telepathic. In this one, the bear is clearly mute. He just hugs stuff.
