Environmental scientists are warning of a sixth mass extinction, pointing to a decline in vertebrate population sizes, even among species of least concern:
Many scientists say it's abundantly clear that Earth is entering its sixth mass-extinction event, meaning three-quarters of all species could disappear in the coming centuries. That's terrifying, especially since humans are contributing to this shift.
But that's not even the full picture of the "biological annihilation" people are inflicting on the natural world, according to a study published Monday [open, DOI: 10.1073/pnas.1704949114] [DX] in the Proceedings of the National Academy of Sciences. Gerardo Ceballos, an ecology professor at the Universidad Nacional Autónoma de México, and his co-authors, including well-known Stanford University biologist Paul Ehrlich, cite striking new evidence that populations of species we thought were common are suffering in unseen ways. "What is at stake is really the state of humanity," Ceballos told CNN.
The authors: Gerardo Ceballos, Paul R. Ehrlich, and Rodolfo Dirzo.

11,700 years ago, the Earth suffered a catastrophic climate change. As the ice age ended, sea levels rose by 120 meters, the days grew warmer, and many kinds of plant and animal life died out. But one animal began to thrive more than ever before. Homo sapiens, which had already spread to every continent except Antarctica, came up with a new survival strategy. Today, we call it farming.
Thanks in part to that innovation, humans survived to witness the dramatic transition from the Pleistocene epoch to the Holocene—it was the first such geological transition in almost 2 million years. But now geologists say we're witnessing another transition, as we move from the Holocene into an epoch called the Anthropocene. Here's what that means.
[Continues...]
Scientists have found over 200 new minerals that exist only due to human activity:
Scientists have identified 208 new minerals that owe their existence wholly or in part to humans. Many in the list have been found down old mine tunnels or on slag heaps where water and even fire have had the opportunity to work up novel compounds.
It is another example, the researchers argue, of our pervasive influence on the planet. New minerals and mineral-like compounds are now being formed faster than at anytime in Earth's history, they say. "These 200 minerals are roughly 4% of the total known minerals, but they all occurred in the last couple of thousand years, most in the last couple of hundred years," explained Robert Hazen from the Carnegie Institution for Science in Washington DC.
[...] It is further evidence, if more were needed, that Earth has now entered a new epoch. Currently, geologists label the time since the last ice age, 11,700 years ago, as the Holocene. But there is a push to introduce a new classification to reflect the immense, planet-wide changes driven by humans in recent decades - and for it to be called the Anthropocene Epoch. The list of new man-mediated minerals bolsters the case.

Welcome to the Meghalayan Age - a new phase in history
The official history of Earth has a new chapter - and we are in it. Geologists have classified the last 4,200 years as being a distinct age in the story of our planet. They are calling it the Meghalayan Age, the onset of which was marked by a mega-drought that crushed a number of civilisations worldwide.
The International Chronostratigraphic Chart, the famous diagram depicting the timeline for Earth's history (seen on many classroom walls) will be updated. It should be said, however, there is disquiet in the scientific community at the way the change has been introduced. Some researchers feel there has been insufficient discussion on the matter since the Meghalayan was first raised as an idea in a scholarly paper [DOI: 10.1002/jqs.2565] [DX] six years ago.
[...] The Meghalayan, the youngest stage, runs from 4,200 years ago to the present. It began with a destructive drought, whose effects lasted two centuries, and severely disrupted civilisations in Egypt, Greece, Syria, Palestine, Mesopotamia, the Indus Valley, and the Yangtze River Valley. It was likely triggered by shifts in ocean and atmospheric circulation. The Meghalayan Age is unique among the many intervals of the geologic timescale in that its beginning coincides with a global cultural event produced by a global climatic event, says Stanley Finney, professor of geological sciences at Long Beach State University and Secretary-General of the International Union of Geological Sciences (IUGS), which ratified the ICS proposal.
The middle phase of the Holocene will be referred to as the Northgrippian, and runs from 8,300 years ago up to the start of the Meghalayan. The onset for this age was an abrupt cooling, attributed to vast volumes of freshwater from melting glaciers in Canada running into the North Atlantic and disrupting ocean currents. The oldest phase of the Holocene - the exit from the ice age - will be known as the Greenlandian.
Scientists are still working on defining the (ongoing) Athropocene and some have criticized this new definition.

...to another red herring. Just because a part isn't explicit doesn't mean it's missing.
Let's analyze the post in question:
First, there's an explicit claim at the end that I'm "holding us back". It's based on the unfounded assertions that a) I'm a member of the "right-minded" class who opposes some productive, creative minority (what makes it a tu quoque fallacy argument is the insistence that I'm suffering from the same problems I decry and hence, by insinuation my argument can be ignored), b) Heinlein "had major issues" so we can again safely ignore his quote (ad hominem fallacy), c) there is some objective viewpoint called the "US of A" which can determine my status as a right-minded hold-backer and once again, ignore the Heinlein quote.
All I can say is that as a near-libertarian, I'm far more liberal on economic, social, and individual liberties than most people on SN (and definitely more liberal than the crowd who thinks I have magic mental failwaves to hold people back with my mere opinion). In particular, I don't "hold" people back. Instead, I see the major problem as one of consequences. Many advocates for various sorts of actions don't consider the consequences of their actions. They merely assume things will become better as a result of the action. For example, if one glances at the article of the story, it is strongly implied that climate change is more serious than habitat destruction.
Notice how "climate change" which is actually anthropogenic global warming is listed first. But wouldn't you think that turning more than a third of the Earth's surface into farmland or pasture would be a bigger deal than the mild global warming forecast for the next century? That level of habitat destruction is climate change in itself, no less, and yet it's in its own mental compartment. Climate researchers are notorious for going through great efforts to remove the effects of habitat destruction from their data (such as filtering out urban heat island effects from temperature data).
Similarly, notice how generic "humanity" is blamed for everything, but the most significant problems are occurring in Africa (note that all the animals mentioned above as being affected by "poachers" are African), Asia, and other high population, impoverished areas. These are areas that would be the worst affected by global warming mitigation efforts - which let us note, have been spectacularly useless to date aside from making poor people poorer.
This is the typical tunnel-vision syndrome. These authors and the journalist are so blinded by ideology that they can't properly list the worst causes of species decline and extinction nor implicate the people and regions most responsible for such.
Anyway, anyone basing solutions off this ideology will have the problem that it will fail. They won't understand the problems well enough to make things better and even in parts where they do, they won't apply solutions that work (such as creating developed world societies). At that point, some scapegoat needs to be blamed for the failure. Apparently, I've been nominated. But my take is people, who correctly predict both the problems you face and the failures you achieve, but who have taken no action to inhibit your course of action, aren't really holding you back.

Raising a tangential issue is not a red herring when it's done in a way that does not detract from the original conversation. Either you are implying that I'm trying to defend AC's point by not arguing it (which is inaccurate and unjustified), you believe I'm somehow preventing you from continuing that conversation with them (how exactly?) or you are carelessly misusing terms of which you have incomplete understanding.
Your reply was structured as follows:
A reasonable reader would assume that the sentence you cite before alleging fallacious reasoning is the statement you believe is fallacious. Here you are talking entirely about the second paragraph of his comment, which is not the one you originally cited.
AC's comment separates that part in a separate paragraph from the rest of his comment. This implies a break in the line of reasoning and beginning the presentation of a new idea. Therefore, the only link between the first and second paragraph one can presume are those explicitly specified, of which there are none. As such, the most sensible interpretation of his comment is that it contains two separate points, the first being a moral judgement of you and the second being inconsistent drivel.

The second paragraph elaborates to some degree on the statement of the first. I discussed the second paragraph since that gave insight into the poster's statement of the first paragraph.
Sometimes that is true, but not in this case and certainly not as a general rule. I wouldn't even consider it a rule for completely different posts under different stories. You have to look at the context of the writing to decide if it is unrelated.

Or someone playing whack-a-mole with the productive members of their society.
It's worth noting here that the "luck" had been in play for decades before 1970. For example, the infrastructure for breeding/discovering and distributing more efficient strains of crops had been around globally since after the end of the Second World War, and in place in the developed world for at least a century before that. So the agricultural gains or "luck" that have permitted humanity to grow to its current extent has been around since well before the 1970s when Paul Ehrlich made his extremely erroneous predictions.
He also ignored economics. There's a variety of natural ways for humanity to deal with scarcity of a natural resource, by using it more efficiently or by using something else instead.
My view is that to say that Paul Ehrlich was wrong merely because humanity was "lucky" is to insult the billions of people who have toiled hard to make the Earth a better place and tame the problems that never became serious.

That said, one thing is definitely true (and I say this as someone who despises most ecological activists): we humans occupy too much of the planet's surface. There is too little space left for other species to exist unmolested. What spaces do exist (national parks, for example) are isolated islands with little opportunity for exchange between them.
The effect is probably most visible on the higher level predators. Cityfolk here celebrate every time someone actually sees a wolf, becuase the farmers and ranchers had totally driven them from the country. A bear? That's a real rarity. Of course, once a predator is spotted, some sort of unfortunate accident quickly follows. The local farmers know nothing [quickmeme.com]...
We pressure 2nd world countries (Brazil, for example) to preserve their wilderness. What we aren't doing is making efforts to rebuild our own. The forests in Europe are expanding - which is great.
