I love trees because they have many different shades of green, so many that it’s almost impossible to count When I paint a picture of a tree I [12] use many shades of green and many more shades of brown. My favorite thing about trees is that they always seem to have a glow around them. I love trees because they always smell so fresh and clean. I like to go to the nursery because I [13] 1ove the smell of trees, it’s so refreshing. It’s a glass of cool water on a hot day, or a damp cloth on a hot forehead.
    One of my favorite things about trees is that they are fun to climb. I started climbing trees when I was very little. I especially like to climb my grandpa’s apple tree. I love to wind through the branches, and climb up to a board that has been placed there. [14] Once up. I like to think and relax, or bring a book up there with me. It’s fun to let my imagination run awav with me while eating apples.
    I love trees in the autumn when they display their beautiful colors. In the autumn time, splashes of red, yellow, orange, and green decorate the mountainsides. The maples go red, the oak and aspen go yellow while the evergreens maintain their beautiful shade of green.
    [15] Trees make life possible because they use the carbon dioxide and release oxygen which makes it so that we can breathe. If we exterminate trees, the effects could be fatal. There may be global wanning, lack of oxygen, and we would definitely not have any lumber or paper.
