Trees reverse the hazardous effects of excess carbon dioxide gas in our environment. They make fresh air and regulate temperature. They are teachers and playmates that grow with you throughout the years and may even outlive you. They are beautiful. There are no disadvantages of trees at all.I am planning an empress tree, named after my little sister Kate. I hope that aside from providing a better, cleaner environment for the earth we live in, it provides joy and peace of mind to my little sister, and that she will learn to appreciate the beauty of trees and nature in general. One day, both of us will look back on the growth of this tree and remember the fond memories as we grew up together.
