Earth's Resources Used Up at Quickest Rate Ever in 2016 (france24.com) 323

Posted by msmash from the save-yourself dept.
An anonymous reader writes: In just over seven months, humanity has used up a full year's allotment of natural resources such as water, food and clean air -- the quickest rate yet, according to a new report. The point of "overshoot" will officially be reached on Monday, said environmental group Global Footprint Network -- five days earlier than last year. "We continue to grow our ecological debt," said Pascal Canfin of green group WWF, reacting to the annual update. "From Monday August 8, we will be living on credit because in eight months we would have consumed the natural capital that our planet can renew in a year."

The verbiage used sometimes tends to anthropomorphize consumable resources in a way that begets images of hippies in a drum circle.

        Well, it's based on empirical data. You'll have to provide your personal definition of "real science" for me.

        Empirical data of the rate of consumption is insufficient. Without measuring whether we're really depleting resources faster than they can be replenished, any so-called "allotment" is little more than a fiction. It's an arbitrary number.

        If you had done this study in the late 1700s, they would have said that we were at the limits for how many people the world could support, too. Since then, modern agriculture has increased crop yields, brought water to fertile soil that was previously too dry to grow crops, and provided machines that can pick crops at a rate that makes it possible to support a much larger population.

        Thus, any discussion of an "allotment" is predicated upon the false assumption that resource shortages are fundamental problems with the world that cannot be corrected through technological means of increasing those resources. It is also predicated upon the dubious assumption that resource shortages won't take care of themselves without out intervention. For example, we panic about CO2 levels, worrying about a runaway greenhouse effect, forgetting that our greenhouse gas percentages are dramatically lower than they were in the distant past. This isn't an experiment. We already have empirical data from previous periods with high greenhouse gas numbers, and we know what happened: plant life flourished, died, got buried, turned into coal, and served as a carbon sink. Anyone arguing that this won't happen again is making an extraordinary claim that demands extraordinary proof.

        This is not to say that global warming isn't a concern. It is. It has the potential to turn fertile lands into deserts and vice versa. It has the potential to seriously disturb the geopolitical climate of our planet, and to make the U.S. become much more dependent upon foreign food sources (Canada in particular). It has the potential to raise the sea level, flooding coastal areas where lots of people live. It can make hurricanes and tornadoes more prevalent, costing human lives. But I think it is important to talk about the concern realistically instead of Chicken Littling the subject and acting like we're about to destroy the world. We really aren't. Earth was around for billions of years before us, and will probably be around for billions of years after we're gone.

            It isn't that simple. The growth rate of plant life depends on the amount of CO2 in the atmosphere. More CO2 leads to faster plant growth. Within a certain band (which we're likely well inside), the planet corrects for variations in levels of CO2 and other greenhouse gases. That's why we don't have a global extinction event every time a volcano erupts and belches methane into the atmosphere.

      It is true that CO2 stimulates plant growth, if you isolate other factors. The problem is that we are deforesting our planet, so the net change in plant biomass is negative. Furthermore, the excess CO2 in the atmosphere is about 37% of the existing 3E12 tons of CO2 in the atmosphere, or 1.13E12 tons of excess CO2 from human activities. A single km^2 of rainforest contains about 356 tons of biomass (wikipedia), so assuming it's all carbon (it's not) we'd need another 3.2E9 km^2 of rainforest to consume all of the excess CO2 in the air. The earth's surface area (including oceans) is only 5E8 km^2. So we'd need 6.2 earth surface areas of Amazon rainforest to sequester all of the extra CO2 in the air. You see, the carbon stores were saved up from fossilization over millions and millions of years and we've attempted to release all of them into the atmosphere in about 100 years. The earth cannot "bounce back" from such a rapid change, it will take millions and millions of years for geological processes to bring carbon back into the Earth's crust. Hope that you see now this is a major problem that won't be solved by sitting back and watching. My sources are: https://en.wikipedia.org/wiki/...

        Who said it needs to go into the crust? You know what really likes carbon on this planet? Everything.

        Also, while tree-sequestered carbon can stay in that form for millennia after the tree is cut - carbon sequestered into plastic takes millions of years to become CO2 again.
        And we could just suck it out of the air [wikipedia.org] and pour it into a hole in the ground. [wikipedia.org]
        It's just that the trees are far more efficient and a LOT cheaper to produce.

        Also, forget rainforests. It's plankton that's making most of the air. [nationalgeographic.org]

    • We aren't using up any of those resources. We can get it back using clean energy such as solar or nuclear.

Build more electricity production facilities (solar, nuclear) and we won't run out of anything. We have enough solar or nuclear potential to last millions of years.

    So, uh, what about all the minerals that are on the ocean floor and deeper than current technology makes it economical to mine? Are those resources "used up"?

    Eventually we'll run out of oil and gas to burn, but last I checked we have a crapton of unused land for solar and if we really had to there's more thorium and breedable uranium than we know what to do with...

    The ecosystem may take a hit from all this increasing activity, sure. But do humans even need it to remain viable as a species? Just how close are we to being able to grow all our food with genetic engineering, and to make all our medicine with genetically engineered organisms in vats?

    I'm under the impression that this is basically possible today, it's just a matter of how much money is available to develop the strains you want. Various FUD about genetic engineering has severely curtailed the interest in it.

    • The cost of mining materials disolved in the ocean has been estimated to be over 10,000 per ounce with current technology.

      The key bit is we are consuming many resources like this.

      Magnesium, zinc, chromium (stainless steel), manganese, molybdenum, iron, coal, etc. etc. etc.

      Recycling is less to much less effective than 100%.

      The real key was holding a much lower population. We didn't do that. It's already too late.

    Some of the items are scary spot on (like the amount of carbon dioxide we would see in the atmosphere).

    A bunch of MIT types calculated that based on total assets in the earth (not just available to extract), we would hit several "limits to growth" between 2020 and 2100.

    For example: We used as much chromium in 2014 as we did from 1900 to 2000 combined.

    here's a summary of the 30 year update.
    http://www.unice.fr/sg/resourc... [unice.fr]

    Many of their projections are following.
    Food is a little higher- but so is population.

    Here's the unavoidable situation they said we would hit.

    Using so many resources that we overshoot the carrying capacity of the earth and then permanently lower it as a result. So if 6 billion were what it could carry for a very long time, by going to 12 billion, we might reduce the capacity to 3 billion.

    And it projects a very rapid population reduction. 70 years to fall from 12 billion back to 1950s level populations.

    The projection is we'll run low on multiple indusrial metals at the same time and prices of those metals will skyrocket.

    Now the fun bit. It's too late to do anything about it. We passed the point of no return back in the 1990s. It's a genuine "bend over and kiss your ass goodbye" situation.

      IMO, they're probably wrong, because they're ignoring fungibility. As the cost of the rarer metals goes up, other materials will take their place, and the net impact on society as a whole will be minimal.

      In the grand scheme of things, you really only need a couple of metals to get things done—iron and copper. Fortunately, these are also two of the most plentiful metals in Earth's crust, so we're not going to run out of either one for the foreseeable future, though the cost of extracting copper may go up as the quality of ore deposits decreases.

      As for the others, right now, people use chromium because of stainless steel, but powder coats or sealants could serve the same purpose in many situations. We might run low on lithium, which is a problem for batteries, but we're also on the cusp of getting supercapacitor capacity to the point where many uses of lithium will no longer be needed, making that largely moot in the long term. And so on. And we use metal for many things that we could use plastics for, too (either oil-based or plant-based).

      Like I said, fungibility.

      On the other hand, the three-gorges dam in china apparently slowed the earth's rotation by about 0.06 microseconds, and shifted the pole position by about two centimeters.

      Of course if we extrapolate this data and we continue building dams at the current rate, we will probably cause catastrophic damage to the earth in the next million years (unless we go extinct by then). Maybe we should stop building dams now before it is too late.

      FWIW, what Mr. Barton said was actually this...

      I am going to read a paragraph which is, if true, very ironic. And this is from Dr. Apt’s paper, and I quote: ‘Wind energy is a finite resource. At large scale, slowing down the wind by using its energy to turn turbines has environmental consequences. A group of researchers at Princeton University found that wind farms may change the mixing of air near the surface, drying the soil near the site. At planetary scales, David Keith, who was then at Carnegie Mellon, and coworkers found that if wind supplied 10 percent of expected global electricity demand in 2100 the resulting change in the earth’s atmospheric energy might cause some regions of the world to experience temperature change of approximately 1 degree Centigrade.’

      This Dr. Apt's paper was poor
