Plants make our whole world. Without plants, we could not live, and vice versa. Plants make the oxygen in the air that we need to breathe. We exhale the carbon dioxide that plants breathe. We also depend on many plants as food. They provide us with most of the nutrients we need to survive. One last thing, and very much not the least, plants are beautiful. They make our world comfortable, and easy to look at. So why not look at these plants, and give them some color. All of our coloring pages are free.
