Oxygen is the most important thing in life in order to stay alive right? Well, have you ever wondered what types of objects contain useful oxygen that we as humans can use? Trees, trees contain the oxygen we need in order to stay alive. Without trees you and I would not be typing or drawing as we speak, read or draw. Did you know that just one mature tree gives off enough oxygen in one season, to allow ten people to inhale for a year? It's true, just one single mature tree will provide enough oxygen for ten people to breath for one entire year. Isn't that absolutely amazing? Trees and their forest also act as a humongous filtration system that cleans the wonderful clean air that we breath. But that is not all, these living objects do a lot more than that. Trees are also good noise mufflers as well. What I mean by that is, they subside the amount of noise that is heard around neighborhoods caused from cars, planes, trains, and even freeways. And get this, they muffle noise almost just as good as brick walls do, how about that huh. One main reason that trees are loved is because they provide shade for us when it is hot, and force breakers when there is snow storms in the winter. Did you know that some city areas that have little or no trees are more likely to be hotter than an area that has a handful of trees planted? Yes this fact is also true. Temperatures can reach twelve degrees higher in city areas that have little or no trees. Wow, there is so much information on trees that it makes you realize that you have been taking the existence of a single tree for granted. Learning “how to draw a tree” is a very simple process when done right. This tutorial provides step by step instructions and two different aspects of a tree that will come in handy when you want to include one in a sketched picture or drawing. Since I have given you some useful information in this description, I think it is time that you learn “how to draw tress step by step” right now. Remember you can also include some apples or cherries on the tree that you draw, you know to dress it up a little. I shall return people, until then I will see ya later.
