Should We Look on the Bright Side of the 6th Mass Extinction? – Animalista Untamed

GR: Here’s the case for optimism for the great loss of species and a literate response that the arguments supporting the case are rubbish. And rubbish they are. The optimistic professor making the case seems to forget that we can only be optimistic when we know fear. Our optimism can be cowardly (accepting) or courageous (challenging). Knowing what might happen and hoping for a better outcome, the courageous will fight for that outcome while the coward will sit smug waiting for the good to come. The optimistic professor appears to be on the smug side of this divide.

I have to assert that the professor’s optimism is more than just cowardly, it is based on inaccurate premises. Here’s one clear example: The result of humans behaving naturally may be the end of life on Earth. Our planet is truly like an isolated petri dish with limited resources. Humans are behaving naturally within the bounds of evolution and ecology as the professor says, but so are the bacteria that consume all the resources in their little dish and then die leaving behind no life at all.

The idea that we want to become acquainted with the few hardy species that will survive the Anthropocene and be our companions on the other side inspired me to write a book about weeds. I guess the work represents a cowardly response to fear but with resignation instead of smugness. Okay, that’s a bit pretentious. My book also represents simple curiosity and appreciation for the amazing plants that thrive in adverse environments. I plan to continue arguing for population and pollution control and a societal shift toward ecological restoration of damaged ecosystems. But that doesn’t seem truly courageous, it just seems like the natural thing to do.

Here’s Animalista Untamed’s critique of Professor Chris Thomas’s new book Inheritors of the Earth, How Nature is Thriving in an Age of Extinction.

Animalista Untamed.

“One man thinks we should. Stop worrying about what is happening to the planet – just kick back and enjoy the ride. That is the message of ecologist Chris Thomas’s new book ‘Inheritors of the Earth, How Nature is Thriving in an Age of Extinction”. “It is time” he writes, “for the ecological, conservation and environmental movement to throw off the shackles of a pessimism-laden, loss-only view of the world.”

“We’ve now become all too unhappily familiar with the ‘Anthropocene’, the word coined by Dutch Nobel Laureate Paul Crutzen to describe this new age, the age in which Man has played havoc with the entire functioning of the planet. We’ve altered the make-up of the atmosphere, the chemistry of the oceans, changed the climate itself. Glaciers are melting, sea levels rising. We’ve depleted biodiversity, plants and animals, and messed up their distribution. We’ve rerouted rivers, drained lakes, razed forests and covered the Earth in highways and cities. And all the while our own population has exploded, 7.4 billion today and an expected 9.7 billion by 2050.

“What is there not to be alarmed about?

“Anthropocenists (by that I mean the vast majority of ecologists who are concerned about the repercussions of human activity) propose that if we have the technology to so damage the planet, why can’t we turn technology to its healing? Hi-tech geo-engineering such as air cleaning plants, altering ocean chemistry to absorb more carbon, or capturing carbon emissions from power stations and factories. Maybe we could even modify the weather. A luxury travel company that promises perfect wedding weather for the big day thinks we can. Expert opinion says otherwise: “The scale of the Earth’s atmosphere is far too great to tamper with—at least for now.” according to meteorologist Bruce Broe.

“But Professor Chris Thomas’s thinking runs on altogether different lines, and he’s nothing if not a glass-half-full man. In this age of mass extinction, he says, nature will do what it always does – fight back.

“A quick summary of his thinking –

  • “Man is an animal and just as much a part of Nature as a bird or a fish
  • “Contrary to what we are constantly being told, Nature is thriving. There are biodiversity gains as well as losses, and “the number of species is increasing in most regions of the world”
  • “The essence of life is eternal change  – everything lives, evolves, dies. There is no stasis in Nature. We need to embrace the change and forget about trying to hold back the hands of the clock

“Taking each of those points in turn:” –Animalista Untamed. (Should We Look on the Bright Side of the 6th Mass Extinction? – Animalista Untamed.)

When the Global Wildlife Decline Reaches Zero

Questions About Climate Change and Wildlife Decline

GR: The research and the various projections of how Earth is warming and how the warming will manifest in planetary events and conditions is based on studies of conditions recorded in sediments and fossils deposited during Earth history. Specialists have calibrated and tested the records in many ways and believe they are reliable. So I want to pose a question:

What do we do to prevent a climate cataclysm that threatens life on earth?

We can stop arguing over the cause of the current and forecast warming. It is important only in the way that understanding the cause might help us prevent the catastrophe. There’s some discussion of this question following my prediction of the year that life ends.

The Global Wildlife Decline

We must also deal with a related issue. Records of wildlife numbers show that a global decline in large and small animals and plants is underway. The creatures that process fallen leaves, branches, and animals to create soil, the creatures that pollinate the plants that cover and protect the soil from erosion, and the animals that feed on the smaller creatures and prevent pockets of explosive population growth are all disappearing – rapidly. The records are based on thousands of studies conducted over decades and are generally accepted as reliable. Here’s the question:

What are we going to do to prevent an ecological disaster that follows the loss of stable soil and vegetation?

The answer to this question has more dimensions than the climate question. We have to look at species and species groups to see what is causing their decline. We should begin now, because the current direction is toward total disappearance of life on Earth.

It is customary for climate scientists to predict the consequences of global warming and place time scales on the changes. I haven’t seen any detailed studies where scientists projected animal declines to devise time scales for the changes. Here’s a simple scale based on the assumption that the future may be predicted from the past: It’s based on the work of a consortium of groups led by the World Wildlife Fund. The groups have traced changes in animal numbers since 1970. During that period, total numbers of fish, birds, mammals, amphibians, and reptiles declined 58%.

The End of Life on Earth By the Numbers

For my prediction, I’m using the average rate of decline from 1970 to 2012 to predict the year that all vertebrate animal life on earth is gone. The average annual decline the World Wildlife Fund Group observed is 1.38% per year (58% divided by 42 years). If the decline continues at 1.38% per year, numbers would fall by 11% to 69% [58+ (1.38*8)] in the eight years from 2012 to 2020. A simple justification for using the average decline is that animal populations go through cycles of increase and decrease. During the period 1970-2012, some populations probably increased while most declined. An average number (1.38% per year) should blend the increases and decreases.

If the average rate of decline holds steady at 1.38%, the total decline of vertebrates will reach 80% by 2028, 91% by 2036, and 100% sometime in 2042. Since it’s too fantastical to believe that all animals will be gone by 2042, we have to expect that the rate of decline must decrease. However, it is difficult to guess at what point it might stabilize.

Animal numbers will probably continue to fall for at least the next three years. So, by 2020, roughly only three out of the ten animals around us in 1970 will remain. The number will continue to fall, but probably at a slower rate.

Failure to answer either the climate or the wildlife question and pursue the solution will result in global disaster. Much that is beautiful, peaceful, and reliable will go away.

Answering the Climate Question

We’ve known for some time that 2-degree Celsius global warming would result in destructive storms, droughts, and sea-level rise. Below I’ve included part of a European Geosciences Union article from a couple of months ago that provides a bit more explanation of what the warming means for our future and our children’s future, and what we have to do to prevent the problems.

Removing CO2 from the air required to safeguard children’s future

“Reducing greenhouse-gas emissions is not enough to limit global warming to a level that wouldn’t risk young people’s future, according to a new study by a team of scientists who say we need negative emissions. Measures such as reforestation could accomplish much of the needed CO2 removal from the atmosphere, but continued high fossil fuel emissions would demand expensive technological solutions to extract CO2 and prevent dangerous warming. The study is published today in Earth System Dynamics, a journal of the European Geosciences Union.

“Continued high fossil fuel emissions would saddle young people with a massive, expensive cleanup problem and growing deleterious climate impacts, which should provide incentive and obligation for governments to alter energy policies without further delay,” says lead-author James Hansen, a professor at the Columbia University Earth Institute in the US, formerly at the NASA Goddard Institute for Space Studies. The team estimates that today’s young people may have to spend up to 500 trillion euros on technologies to extract carbon dioxide from the air, if high emissions continue.

“In contrast, if rapid phase-down of fossil fuels starts soon, CO2 could be removed from the atmosphere at relatively low cost. Better agricultural and forestry practices, including reforestation and improving soils, would then be able to achieve most of the CO2 extraction needed to prevent global-warming’s most dangerous consequences.

A safe target

“Impacts of climate change include more frequent and severe heat waves, storms, floods and droughts, as well as sea-level rise, which could affect millions of people living in coastal areas. “Sea-level rise this century of say half a metre to a metre, which may be inevitable even if emissions decline, would have dire consequences; yet these are dwarfed by the humanitarian and economic disasters that would accompany sea-level rise of several metres,” the team writes in their study, which has been peer-reviewed.

“We show that a target of limiting global warming to no more than +2°C relative to pre-industrial levels is not sufficient, as +2°C would be warmer than the Eemian period, when sea level reached +6-9 metres relative to today,” says Hansen. The Eemian ended some 115,000 years ago and was a warm period in the Earth’s history between two glacial ages.

“The danger, according to the Earth System Dynamics study, is that a long-term global average temperature of +2°C – or even of +1.5°C, the other temperature limit discussed in the 2015 Paris Agreement – could spur ‘slow’ climate feedbacks. In particular, it could lead to partial melting of the ice sheets, which would result in a significant increase in sea-level rise as happened in the Eemian [see note].

“The Hansen-led team says that atmospheric CO2 should be reduced to less than 350 parts per million (ppm) from its present level of about 400 ppm. Global average temperature reached +1.3°C above pre-industrial levels in 2016 and will increase at least a few tenths of a degree more during the next few decades because of the delayed response to past increases in CO2 and other gases. Reduction of CO2 below 350 ppm will cause temperature to peak and slowly decrease to about +1°C later this century. This goal requires negative CO2 emissions, that is, extracting CO2 from the air, in addition to rapid phase-down of fossil fuel emissions.” –European Geosciences Union (EGU – News & Press – Removing CO2 from the air required to safeguard children’s future.)

Protect kids from pesticides as they go to school

Pesticides Poison Children of All Species

GR: The article below focuses on human children. Many of us would like to focus on wildlife as well. All young creatures are especially sensitive to pesticide poisons. The massive decline in numbers of wild animals is our fault. We need to teach or remind children, parents, teachers, and schools that our wild neighbors need our protection. Everyone is aware of the plight of the bees and Monarch butterflies. However, many other species also suffer from the toxic materials we spread across the land. Without focused effort on wildlife and nature conservation, silence will spread across the Earth like the Nothing in the Neverending Story. Let’s ban pesticides and then move on to eliminating our other destructive impacts too. Neighborhood schools are a great place to start.

“School policies must protect children from pesticides by adopting organic land and building management policies and serving organic food in cafeterias. At the start of the school year, it is critical for school administrators to make sure that students and teachers are learning and teaching in an environment where no hazardous pesticides are used in the school’s buildings or on playing fields. It is also essential that children have access to organic food in food programs and manage school gardens organically.

Send a letter to your local officials urging them to tell school districts to adopt organic management and serve organic food to students.

“In addition, there are other things you can do:

“Whether a parent, teacher, student, school administrator, landscaper or community advocate, there are steps that should be taken to make sure the school environment is a safe from toxic chemicals, as the new school year begins.

For Parents and Teachers

“Because children face unique hazards from pesticide exposure due to their smaller size and developing organ systems, using toxic pesticides to get control insects, germs, and weeds can harm students much more than it helps. The good news is that these poisons are unnecessary, given the availability of practices and green materials that do not poison people or the environment.

“Studies show children’s developing organs create “early windows of great vulnerability” during which exposure to pesticides can cause great damage. This is supported by the findings of the American Academy of Pediatrics (AAP), which concluded, “Children encounter pesticides daily and have unique susceptibilities to their potential toxicity.” You can help to eliminate children’s exposure to toxic chemicals by urging school administrators to implement organic management practices that use cultural, mechanical, and biological management strategies, and, as a last resort, defined least-toxic pesticides. See Beyond Pesticides ManageSafeTM database for managing all insects and weeds without toxic pesticides.” –Beyond Pesticides (Continue reading:  Gmail – Action of the Week: Protect kids from pesticides as they go back to school.)

Dams could permanently damage Amazon

GR: Deforestation on the land and dams on the river are eating away at the Amazon rainforest ecosystem.

EDGARGO LATRUBESSE Image caption The Amazon basin is the largest and most complex river system in the world (Edgargo Latrubesse)

Dams Threaten Amazon Ecosystem

“The Amazon basin could suffer significant and irreversible damage if an extensive dam building programme goes ahead, scientists say. Currently, 428 hydroelectric dams are planned, with 140 already built or under construction. Researchers warn that this could affect the dynamics of the complex river system and put thousands of unique species at risk. The study is published in the journal Nature.

“The world is going to lose the most diverse wetland on the planet,” said lead author Prof Edgargo Latrubesse, from the University of Texas at Austin, US.

Cascading problems for the Amazon

The Amazon basin covers more than 6.1 million sq km, and is the largest and most complex river system on the planet. It has become a key area for hydroelectric dam construction. But this study suggests that the push for renewable energy along the Amazon’s waterways could lead to profound problems. The international team of researchers who carried out the research is particularly concerned about any disruption to the natural movement of sediment in the rivers. This sediment provides a vital source of nutrients for wildlife in the Amazon’s wetlands. It also affects the way the waterways meander and flow. –Rebecca Morelle (Dams could ‘permanently damage Amazon’ – BBC News).
