This is an encore Green Builder’s Journal discussing the topic of natural resource depletion and sustainability. It is still valid today.
So last time we defined “green” as any effort or strategy undertaken to reduce the demand of natural resources. Any effort. Any strategy. Any natural resource. It’s that simple. You can put the label of “green” on any effort or strategy that achieves the goal of reducing demand on any natural resource. I repeated it on purpose to emphasize that when you hear the word “green”, you should ask yourself; how does this reduce the demand on a natural resource? If it doesn’t, it isn’t “green”.
Of course the interesting fact about this “green” movement is that even if the entire world took a “green” stance tomorrow all it would actually do is stall the issue of natural resource depletion. Think about it. Its math. Demand obviously grows with population. To illustrate, let’s use simple numbers, say that today one hundred people use one hundred trees, or one tree per person per year. If everyone adopts “green” behaviors and cuts the average use to a half tree per year, yet the population doubles to two hundred people…..well then one hundred trees still lose their lives every year. Even though we can say we’re all “green”, we’re still headed for natural resource depletion; in this case trees. We just delayed the process because I’m pretty sure we’ll keep adding to population.
Seems like a good time to introduce the term “sustainable”.
Actually before I do that, let’s talk about natural resources. I know we all remember from grade school geology, biology, chemistry and geography what a natural resource is (unless you slept through those classes), but what do we mean by natural resource in this context? Well, virtually all the “stuff” in our lives started as a natural resource. Yes there are some man-made chemicals that have enhanced our lives, but for the most part everything we see, smell, taste, hear and touch started as a natural resource. Trees, water, coal, oil, gold, copper, etc are examples of natural resources. As humans, we’ve used natural resources on their own, and in combinations, to create virtually everything in our lives. For thousands of years, the ratio of humans to natural resources was so low, no one really cared about using as many natural resources as they desired because it was incomprehensible that a planet as large as ours could actually run out of what appeared to be an endless supply of natural resources.
Of course it was probably as equally incomprehensible to those early humans that eventually there would be six billion of us. Guess what? There is. Not only that, but it only took 34 years to go from three billion to six….and best guess is about another 25 years to double again to 12 billion. That ratio of humans to natural resources I spoke of, has done a massive flip flop to the point where I don’t think any one of the six billion of us is dumb enough to think that pace can continue unabated. In other words we can’t “sustain” the level of natural resource depletion that this level of population increase will demand. Or can we?
Which takes me back to the word “sustainable” But I’ll save that for next time.
