Human life vs. Tree life.
"I think that I shall never see
a poem lovely as a tree." --Joyce Kilmer.
I think that I shall never see
A billboard lovely as a tree.
Indeed, unless the billboards fall
I'll never see a tree at all. --Ogden Nash

Those quotes are just for flavor. The link is more serious. Let us consider the proposition that human life is more important than tree life. This wide-spread assumption is used to cut down trees to make houses and fishing boats and endless other things associated with adding quality-of-experience to human life. Some of those things may even be necessary instead of being merely enjoyable. On Easter Island, for example, several centuries ago, much of the diet was seafood, so lots of trees were cut to make fishing boats. For them, then, could trees be called "unimportant", if without trees no boats could be built to obtain enough food?
See the connections? If human life is declared to be more important than trees, and if the obtaining-of-food is considered important because human life is important, and if trees are required to obtain that food, then aren't trees important, after all? OK, let's implement a tree-growing plan, to make sure we have the trees we need, so we can cut them to fulfill the requirement that uses them to obtain food. Human life is still more important, right?
The preceding appears fine and dandy, until we add in the fact that human population tends to grow. If human life is so important, then why not make more of it? But how does that affect the availability of somewhat-important trees? Let's pretend that during the course of one human life, 10 trees must be cut down to make all the various things that that human might need in that life, from lumber to firewood to whittlings. I suspect the actual figure is much higher, but the point I wish to make can be reached almost as easily with the figure of 10 trees as with 100 or 1000, so I will pretend that only ten trees need to be cut down, to fulfill the needs of one human life.
We may now start with a stable population of 1000 humans and 10,000 trees. For the moment we assume that each human death is matched by only one birth, and every cut tree is replaced by a seedling or three. (Time out: There is a lumber company that brags about being a "tree growing" company, because it plants two trees for every one that it cuts. However, the advertisements fail to state that the natural death rate of planted seedlings is about 50% --which means they might be staying even with their rate of tree-cutting, but they certainly are not replanting areas that have been deforested for decades.) It is possible that more than 10,000 trees are actually needed, to give them time to grow before being cut, but here I will simplify things by assuming that when the first tree is cut and replaced by a seedling, a full human lifetime will go by before the replacement tree gets cut for the replacement human life. That's the traditional three-score-years-and-ten, of course, so a 70-year-old tree is what is being discussed here, and at that age it can easily be a decent size, especially if it is of one of the fast-growing varieties. Also, we can spread-out the cutting-down of trees, such that during a 70-year life, the 10 trees are each cut at 7-year intervals. Thus our "forest" of 10,000 trees could be described as having 1000 surviving seedlings, 1000 7-year-old-trees, 1000 14-year-old trees, and so on --except that would also require assuming that the humans conveniently experience 100 deaths and 100 births every 7 years, with none in-between. Well, I did say this was a simplification! (And remember you can always multiply these figures by larger numbers of trees-per-human-life, as you think appropriate.)
OK, now let's add one new human to that formerly-stable population of 1,000. Immediately we must cut down a tree to help support that life. But where will it come from? All the 10,000 trees in the "forest" are reserved for use by the previously-existing 1000 humans! Logically, therefore, when expecting the human population to grow, advanced forestry-planning must occur first! And that planning must occur as much as 70 years prior to the birth of that single extra human, to be sure an appropriate tree is ready to be cut! OR, of course, the community can seek to widen its boundaries, to include a larger "forest" that just might happen to already exist out there, unused before now.
Let's look at that latter possibility: Just how big is that "wider forest"? Then we can immediately divide by 10 to find out how many extra humans can be born, taking advantage of the existence of that forest, before we need to worry about advanced forestry planning.
OK, time passes, and now the human population has expanded to meet the available forest resources, and now there is no escaping advanced planning. So, look at the landscape! We need to reserve landscape to plant new trees, so that they will be available when still-more humans are born to that expanding population. But now a new dilemma arises: Humans require landscape, also! Every time a house is built, landscape becomes reserved exclusively for human use, and cannot be used for growing trees.
The final key fact is that landscape exists in limited supply. There is only so much room for BOTH humans and trees, when it is required that 10 trees be available for every human. Well, how important is human life, anyway? Should more humans be born, in spite the lack of sufficient trees?
Do keep in mind the earlier linking of trees with human survival. If the 10 trees are not available, it can be assumed that 1 human will die. Does this mean that human life really is more important than tree life? On Easter Island the humans found out the hard way, and after cutting down the last tree more than 19,000 humans died. On Island Earth there may be more landscape than Island Easter had, but the fact that it is a limited total quantity remains. Thus the conclusion seems to be inevitable. If some other life form is required for human survival, then that life form is exactly AS important as human life, not less important. I am not saying that trees are essential for human life. But other life-forms are. So think about it, the next time you say it is OK to sacrifice that other life-form so that yet-one-more human can exist. Is there a sustainable supply of that life-form remaining? And is abortion an OK way to ensure human life does not exceed its demands upon that other life form? Espedially when that other life-form is as important as human life, after all!
