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

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."

To calculate the date for Earth Overshoot Day, the group crunches UN data on thousands of economic sectors such as fisheries, forestry, transport and energy production.

Earth-warming greenhouse gas emissions, it said, are now the fastest-growing contributor to ecological overshoot, making up 60 percent of humanity's demands on nature -- what is called the ecological "footprint".

I've never even heard of this metric. Is this based on real science or climate activism?

our negative impact on the planet is substantial and that this is accelerating.

You see population growth is rapidly decelerating, albeit still positive. Hence our impact is likely to be decelerating too.

First off, volcanos are dwarfed by the amount of carbon dioxide and other greenhouse gasses that people pump into the atmosphere annually. Secondly, what we pump into the atmosphere came from an area deep underground where it had been sequestered for millions of years. So for millions of years, the trees/plants didn't need to take care of this carbon dioxide and it wasn't part of the natural carbon cycle. Now, though, it's suddenly being tossed into the atmosphere and some people act surprised that the existing plant life can't just magically handle all of the new stuff too.

Will climate change end life on Earth? No, it won't. Might it make life on Earth really horrible for humans? Yes. Our cities on the coastlines (where we've historically loved building cities) will get flooded. Traditional crops won't grow in their usual farm areas and the new areas that have the right temperature might not have suitable farmland/soil conditions. (If you want to grow corn in the new "corn belt" area, it won't be good if that happens to lie on a mountainous terrain.) In short, humans can pay to fix climate change now or we really pay for it later.

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.

The Earth is used up

[Empiric]

Well, we had a good run.

Or, maybe like the entire history of mankind and economics, "used up" means there's demand for more production, or alternative production.

More CO2 is resulting in more foliage. Seems nature has it's own kind of "balancing market".

I'll be looking for a better arbitrary wordplay metric of impending doom.

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.

We ate up all the food...?

[nikkipolya]

How can we end up eating all the food meant for the whole year? Who is giving the food for credit then? The Fed? Are the plants doing "Quantitative Easing" of food then?

in terms of breathable air, pollutants in it are a local problem, not global.

False.
