I had read that Shel Silverstein wrote a book called The Giving Tree.
My mother showed me a video of the whole book.
The Giving Tree is about a small boy who played with the tree while he was small and was cheerful and happy and laughing. After he grew up, he didn't play with the tree anymore and he was always sad and always wanted other things like money, a family, a house...
Soon, he grows up and he asks the tree if he has money, but the tree said he didn't have money, but told the boy "Sell my apples and get money."
After everything, when the boy grows old, he needs a place to rest, and the tree had nothing left. He had given the boy his apples, branches, and even his trunk.
The tree says "I have nothing left. You can't swing on my branches or eat my apples or climb my trunk."
I felt sad for the tree as it gave everything of itself and this book shows the greed of humans and how nature is destroyed.
