Like I said before, trees are not in danger. There are laws protecting most of the rainforests of the world (which, by the way, harbor a hell of a chunk of the earth's biodiversity and really should be conserved) and while it's unfortunate that many of these rainforests are found in corrupt countries with people who would gladly cut down a hundred-year-old Ebony tree to make a few knickknacks to sell to tourists, that's really not the fault of large civilizations and technological progression like people assume. The forests are protected (it is illegal to cut down any endangered tree in most rain forests), it's just a few poachers who break the law to make money.

And in North America, we have the forestation laws as well as natural parks. Most of our forests are protected under the title of "national park", and all the wildlife within them are protected as well. Some parts of forest are set aside for lumber (including paper) production, and some land is bought and leveled for the cattle fields mentioned earlier, but for the most part the large parts of the earth are protected by law.
