Trees are cool. They help the environment out a lot. The normal thing that most people know is that they help get rid of Co2 in the environment. But did you know that trees can also get rid of waste from the ground, and pollution from the sky? Well, they can. Phytoremediation is what it is called to use plants in that such way. Phyto means plant and remediation means to cure. Asparagus plants, and spider plants help to get rid of cigarette smoke and other pollutants in the air. Which is really helpful for the safety and health of the people and other animals that live. Trees can also make the ground water cleaner. It takes the water up through its roots from the ground and it cleans it and sweats it out in the leaves. So if anyone is ever stranded in a forest there will be water in some of the leaves of trees such as Pine trees, eastern cottonwood trees, hybrid poplar trees, and juniper trees. (if you know how to identify trees of the back of your hand this could also be useful. The trees can also team up with bacteria to help the soil become cleaner along with the water in the ground. This related to chemistry because it talks about how the trees cannot only help with the Co2, but can also help with the water and pollutants as well. I never knew that trees were so special. I <3 trees!!!
