Trees take in water and release oxygen. They also provide shade for people. If you don't want to do any tree work, hire a company that will do it for you.
Another important thing that you will need to consider is the height of the tree. Some types of trees are considered hazardous because they are very tall and dangerous to climb. You should make sure that you have a ladder before you try to climb up the tree.
If you try to do the job yourself, you will have a tough time because you will have to deal with the mess you are left with after the job is done.
