The reason for this discrepancy is because the data from the Umweltbundesamt includes construction and demolition waste (see figure below and surrounding text on your linked webpage) whereas the data from the EPA "does not include everything that is landfilled in MSW, or nonhazardous, landfills, such as construction and demolition (C&D) debris, municipal ...
Yes, this figure is consistent with estimates from 20 years ago.
The 1995 paper Endangered Ecosystems of the United States:
A Preliminary Assessment of Loss and Degradation collates some relevant estimates from the literature in Appendix A.
50 United States
85% of original primary (virgin) forest destroyed by late 1980's (Postel and Ryan 1991).
I'm assuming that by "original forests" the video refers to old-growth forests, and that the point considered 100% is the total forest area of year 1630.
U.S. Forest Resource Facts and Historical Trends 1952-2012 provides a graph showing forest distribution by age:
As you can see, forests older than 150 years account for about 15-20% ...
To come up with the emission per child, the original source Reproduction and the carbon legacies of individuals Global Environmental Change Volume 19, Issue 1, February 2009, pages 14-20, is considering an infinite series.
In other words, having one child results in all the lifetime emission of said child, plus all that child's descendants' emissions. ...
There have been a number of studies that investigate how consumer behaviour changes when feedback from a smart meter allows them to understand their usage habits.

This paper looked at the effect of In Home Displays (IHD) from a dozen pilot programs in ...
Leaving aside the fact that termite CO2 production is on few, if any, secondary school syllabuses, its more complicated than that.
Termites are not burning fossil fuels. The carbon they produce comes from decomposing wood. This carbon came from the atmosphere, and as the wood rots this carbon will wind up back in the atmosphere whether termites eat it or ...
How credible is [the claim that salmon catch has increased by over 100,000 tons]?
Let us examine both the weight and number of salmon (see ADF&G Press Releases) per year.
The fertilization was conducted in 2012. Salmon numbers are expected to fluctuate and differ for even and odd years due to the two-year spawn times of pink salmon.
For each year, the ...
"To me this seems complete nonsense."
As it does to anyone that looks any further than the company's own advertising.
McGill University's Office for Science and Society ("Separating Sense from Nonsense") has a report on the magnetic laundry device.
The two key points are that the patent has nothing to do with whether the device actually does anything ...
According to the U.S. Forest Service publication U.S. Forest Resource Facts
and Historical Trends:
In 1630, the estimated area of U.S. forest land was
1,023 million acres or about 46 percent of the total
land area. Since 1630, about 256 million acres of forest
land have been converted to other uses
So 75% of the original forest land is still ...
If she said it in 2014, she wasn't the first.
For example, in a 2012 interview, Professor John Crawford of the University of Sydney said ,
A rough calculation of current rates of soil degradation suggests we have about 60 years of topsoil left. Some 40% of soil used for agriculture around the world is classed as either degraded or seriously degraded – ...
According to "The Modification of Planet Earth by Man," Gordon J. F. MacDonald, Technology Review, Oct/Nov. 1969, pp. 27-35 (official link):
There are at least six ways in which man's activities could perturb the atmospheric heat balance and thus the climate in a significant way. These are: 1. increasing the carbon dioxide content of the atmosphere by ...
Avery gave you a list of "yeses" by moving the goal posts to an issue of organics vs non-organic modern agriculture. Here's a peer-review no to the actual question of historical decline: https://doi.org/10.1016/j.jfca.2016.11.012 It's a study by an employee of Canada's Bureau of Nutritional Sciences
Mineral nutrient composition of vegetables, fruits ...
This answer is now complete. Note all values of cumulative CO2 produced refer to as of end of year 2018.
I have finally found an ExxonMobil document that cited a source, rather than simply state the claim (as is with this and this ExxonMobil site). The document is here and the claim is mentioned in the first paragraph of page 20 of the pdf. Part of the ...
Is Bhutan carbon neutral?
According to "Sustainability in an Emerging Nation: The Bhutan Case Study" published in Sustainability, Bhutan is indeed carbon neutral. The paper makes the following statement "it is interesting to note that only one country, Bhutan, has successfully achieved [carbon neutrality]."
Another paper, "Carbon Neutral Policy in Action: ...
If I'm allowed a little pun on this, it seems the press release uses an America-first definition of environment.
This is a study of water use for power generation in the US.
Despite the shift in source of energy generation, a majority
of electricity generation in the U.S. still derives from watercooled systems. Approximately 40% of the total water
There are several news reports 1, 2, 3, which are all mentioning this study, that is unfortunately not open-source.
The findings were
The research suggests an area covering 2.24 million square kilometers - roughly the combined land surface of Texas and Alaska, two sizeable US states - has been added to global tree cover since 1982.
But it is also ...
Oddthinkings answer is excellent though I'd like to take a slightly different tack to the question.
With some smart meters your bill can change quite dramatically depending on the design of the smart meter.

Q What is the truth?
That would be nice to know, indeed. But the way this problem is formulated it is way too complex to be answered definitively with simple 'yes' or 'no'.
On the one hand, it's a really simple equation of input/output. If the substrate, fertilizer and water are lacking minerals, then the plants will be lacking them as well, as they ...
The massive decline in plant compounds is attested by many studies, but I take it that your concern is whether this is linked to problems in human nutrition. The current answer is that there is not enough research on this subject.
Reeve, J. R., et al. "Organic farming, soil health, and food quality: considering possible links." Advances in Agronomy 137 (...
I think the premise is a bit backwards here. The most direct and shortest answer is: No, it does not depend on so much artificial fertilizer. "A uses B" is not the same as "A depends on B". The plants are not going to die if they have no synthetic fertilizer applied.
1) Non-synthetic fertilizers could be used. There is nothing to cite here, as that would be ...
The question about soil depletion with time has been covered in other answers.
Currently, in some areas, soil mineral depletion is associated with lower amounts of minerals in plants and with iodine, zinc and selenium deficiency in humans (Annals of Botany, 2010, sow-wu.nl Centre for World Food Studies, 2006).
Except in the areas with known mineral ...
