In Case You Hadn’t Heard: 6th mass extinction already underway — and we’re the cause

http://www.usatoday.com/story/news/nation/2015/06/20/sixth-mass-extinction-study/29028887/

The Earth’s sixth mass extinction is already underway — and humans are the driving force behind it, according to a new study.

“Recent extinction rates are unprecedented in human history and highly unusual in Earth’s history,” according to a study published Friday in the journal Science Advances. “Our global society has started to destroy species of other organisms at an accelerating rate, initiating a mass extinction episode unparalleled for 65 million years.”

Researchers used “extremely conservative assumptions” to determine extinction rates that prevailed in the past five annihilation events. Still, they found the average rate of vertebrate species lost over the past century was up to 114 times higher than normal.

13 animals hunted to extinction

Fri, May 06, 2011 at 12:45 PM
Whether it is for the lust of exotic skins, mere sport or — as is often the case — pure fear, numerous species have been wiped out primarily by human hunters in the last couple hundred years alone.

Extinction of your favorite animal more real than you realize

Extinction of your favorite animal more real than you realize

This week a study published in Science Advances has suggested that the extinction of some of the world’s most beloved animals is a clear and present danger. Fourty-four of the 74 largest terrestrial herbivores are now threatened with extinction, 12 of them “critically endangered” or extinct in the wild. Many of the species in decline, suggests the study, “are poorly known scientifically, and [are] badly in need of basic ecological research.” Not only will they die unless we do something, we’ll never know what they are all about in the first place.

Below you’ll see a set of two maps. The map at the top shows areas where large herbivore species exist. The cool colors show places where large herbivores exist, but only a handful of species.

The warmer the color, the more species of large herbivore exist.

F1.large-1

The second map shows where large herbivores are threatened. Save South America, most areas with very few large herbivore species seem to be less threatened.

The following species are currently threatened:
• African elephant (VU)
• Asian elephant (EN)
• Hippopotamus (VU)
• Pygmy hippopotamus (EN)
• Eastern gorilla (EN)
• Western gorilla (EN)
• Malayan tapir (VU)
• Baird’s tapir (EN)
• Lowland tapir (VU)
• Mountain tapir (EN)
• Philippine warty pig (VU)
• Oliver’s warty pig (EN)
• Visayan warty pig (CR)
• Palawan bearded pig (VU)
• Bearded pig (VU)
• Indian rhinoceros (CR)
• Javan rhinoceros (CR)
• Sumatran rhinoceros (CR)
• Black rhinoceros (CR)
• Grevy’s zebra (EN)
• Mountain zebra (VU)
• African wild ass (CR)
• Przewalski’s horse (EN)
• Asiatic wild ass (CR)
• Sambar (VU)
• Barasingha (VU)
• Père David’s deer (EW)
• White-lipped deer (VU)
• Bactrian camel (CR)
• Indian water buffalo (EN)
• Gaur (VU)
• Kouprey (CR)
• European bison (VU)
• Wild yak (VU)
• Banteng (EN)
• Takin (VU)
• Lowland anoa (EN)
• Tamaraw (CR)
• Mountain nyala (EN)
• Scimitar-horned oryx (EW)
• Mountain anoa (EN)
• Sumatran serow (VU)
• Walia ibex (EN)

This study shows three of the best-known species whose populations are contracting as we speak. These herbivores are the African Elephant, the Common Hippopotamus (not common for long), and the Black Rhinoceros.

F3.large

The most recent range polygons for the rhino are not shown here because of “recent poaching pressure.”

The change in population and possibility of extinction in all of these areas is due largely to one (or more) of four elements. Exploitation (hunting), Livestock (problems therein), Land-use change, and Conflict – as in Civil Unrest between warring human factions.

Above you’ll see the percentages of large herbivore species threatened based on these four major threat categories.

NOTE: The total here adds up to more than 100% because each large herbivore may have more than one existing threat.

Black Rhino Officially Extinct

1467436_10151678631130496_1400231111_n

http://www.11alive.com/news/article/312002/40/Western-black-rhino-officially-declared-extinct

LONDON (CNN) — Africa’s western black rhino is now officially extinct according the latest review of animals and plants by the world’s largest conservation network.

The subspecies of the black rhino — which is classified as “critically endangered” by the International Union for Conservation of Nature’s (IUCN) Red List of Threatened Species — was last seen in western Africa in 2006.

The IUCN warns that other rhinos could follow saying Africa’s northern white rhino is “teetering on the brink of extinction” while Asia’s Javan rhino is “making its last stand” due to continued poaching and lack of conservation.

“In the case of the western black rhino and the northern white rhino the situation could have had very different results if the suggested conservation measures had been implemented,” Simon Stuart, chair of the IUCN species survival commission said in a statement.

“These measures must be strengthened now, specifically managing habitats in order to improve performance, preventing other rhinos from fading into extinction,” Stuart added.

The IUCN points to conservation efforts which have paid off for the southern white rhino subspecies which have seen populations rise from less than 100 at the end of the 19th century to an estimated wild population of 20,000 today.

Another success can be seen with the Przewalski’s Horse which was listed as “extinct in the wild” in 1996 but now, thanks to a captive breeding program, has an estimated population of 300.

The latest update to the IUCN Red List of Threatened Species reviews more than 60,000 species, concluding that 25% of mammals on the list are at risk of extinction.

Many plants are also under threat, say the IUCN.

Populations of Chinese fir, a conifer which was once widespread throughout China and Vietnam, is being threatened by the expansion of intensive agriculture according to the IUCN.

A type of yew tree (taxus contorta) found in Asia which is used to produce Taxol (a chemotherapy drug) has been reclassified from “vulnerable” to “endangered” on the IUCN Red List, as has the Coco de Mer — a palm tree found in the Seychelles islands — which is at risk from fires and illegal harvesting of its kernels.

Recent studies of 79 tropical plants in the Indian Ocean archipelago revealed that more than three quarters of them were at risk of extinction.

In the oceans, the IUCN reports that five out of eight tuna species are now “threatened” or “near threatened,” while 26 recently-discovered amphibians have been added to the Red List including the “blessed poison frog” (classified as vulnerable) while the “summers’ poison frog” is endangered.

“This update offers both good and bad news on the status of many species around the world,” Jane Smart, director of IUCN’s global species program said in a statement.

“We have the knowledge that conservation works if executed in a timely manner, yet, without strong political will in combination with targeted efforts and resources, the wonders of nature and the services it provides can be lost forever.”

15 Species Just Won’t Make it Unless We Act Now

Researchers have recently released a paper that details 15 of the most critically endangered species on Earth – organisms that not only are facing what looks to be inevitable extinctions, but are barely receiving any aid to stop it. Now conservationists are calling for the money and expertise that would be needed to help these creatures – ranging from seabirds to tropical gophers – survive.

A study recently published in the journal Current Biology details how a whopping 841 endangered species can still be saved from extinction if countries and organizations commit an estimated net value of $1.3 billion dollars annually towards their safety. However, for 15 of the species highlighted in the report, their chance of conservation success is dropping by the minute.

“Conservation opportunity evaluations like ours show the urgency of implementing management actions before it is too late,” Dalia A. Conde, the lead author of the study and Assistant Professor at the Max-Planck Odense Center at the University of Southern Denmark, explained in a recent statement. “However, it is imperative to rationally determine actions for species that we found to have the lowest chances of successful habitat and zoo conservation actions.”

So just what are these 15 species in trouble? Nearly half the list includes amphibians, and that’s something that shouldn’t be too surprising given that this class of creatures is battling a war on two fronts. (Scroll to read on…)

As things stand, a deadly fungus (Batrachochytrium dendrobatidis) continues to spread and wipe out frog species from the face of the Earth in places like Brazil and Spain. A variant of it (Batrachochytrium salamandrivorans) has even started to affect salamanders around the globe.

Meanwhile, the habitats that these creatures rely on are shrinking and changing in the wake of climate change and human influence. Salamanders are even shrinking, as they increasingly struggle to live in suddenly dry and warming climes.

Six of the 15 species listed also happen to be birds. This, too, is partially a consequence of climate change, where churning air currents and shrinking habitats are leaving migratory species with smaller rest stops and fewer food supplies. Even species who do not travel far are left to compete with invaders, pollution, and, most commonly, deforestation. The Tahiti monarch (Pomarea nigra), for instance, is estimated to total less than 50 in the wild, as livestock pastures are expanding at the cost of forest habitat. (Scroll to read on…)

The Amsterdam albatross - one of the most critically endangered birds in the world - boasts a population that hovers somewhere around 130 birds with only 25 known breeding pairs.

(Photo : Vincent Legendre) The Amsterdam albatross – one of the most critically endangered birds in the world – boasts a population that hovers somewhere around 130 birds with only 25 known breeding pairs.

Most interestingly, three mammal species are threatened, consisting of the Mount Lefo brush-furred mouse (Lophuromys eisentrauti) in Cameroon, the Chiapan climbing rat (Tylomys bullaris) in Mexico, and the tropical pocket gopher (Geomys tropicalis) along the Mexican and Central American coast.

Shrinking habitats are threatening all three, but the reasons vary from urbanization, to human conflict, to costly habitat protection. Some can’t even be reintroduced into the wild through a captive breeding system, as the expertise to raise them is too rare or costly in undeveloped worlds.

That’s why an international effort world be worth it, according to the study. The researchers determined that the total cost to conserve the 841 animal species in their natural habitats was calculated to be more than $1 billion (USD) per year. The estimated annual cost for complementary management in zoos was $160 million.

“Although the cost seems high, safeguarding these species is essential if we want to reduce the extinction rate by 2020,” added Hugh Possingham from The University of Queensland. “When compared to global government spending on other sectors – e.g., US defense spending, which is more than 500 times greater -, an investment in protecting high biodiversity value sites is minor.”

And most encouragingly of all, the researchers found that if these species get the funding they need, 39 percent of them could potentially be pulled out of their endangered status, given their high number of conservation opportunities.

That’s not the case for the most threatened 15, but even for those the researchers argue that taking “an integrated approach” could save them...

Are humans to blame for the mammoth’s demise? Hunting caused numbers to plunge 30,000 years ago, study claims

  • Researchers in Germany have found that hunting significantly depleted mammoth populations in Western Europe around 30,000 years ago
  • They studied the bones of mammoths, horses and reindeer
  • Analysing isotopes ruled out climate change as a cause of population cuts
  • All but a few isolated populations died out 20,000 to 10,000 years ago 

They found that woolly mammoth numbers declined, but that climate conditions as well as food and water supplies for the giant herbivores remained stable.

The woolly cousins of modern elephants roamed northern Eurasia and North America beginning 300,000 years ago, but some 10,000 to 20,000 years ago, all but a few of the isolated island populations disappeared. 

By studying bones, researchers found that numbers of woolly mammoths declined, but that climate conditions as well as food and water supplies for the giant herbivores remained stable, indicating that hunting is the main cause. A depiction of a hunting party using a pitfall trap is shown

Hunting Causing Extinctions in Indonesia

Indonesia’s silent wildlife killer: hunting

Commentary by Erik Meijaard, the Borneo Futures initiative
December 26, 2014

By and large, Indonesia is a peaceful country. In fact, on the United Nations Office of Drugs and Crime’s list of homicide rates, Indonesia ranks number 10, making Indonesians one of the least murderous people on Earth. A ban on gun ownership probably helps, although obviously there are many other ways to snuff out another person. Maybe Indonesia’s general tendency to avoid conflict helps, too.

Whatever the reason why Indonesians are relatively unlikely to kill each other, such favors are not extended to Indonesia’s non-human wildlife. The relative safety of Indonesia’s people does not guarantee similar security for its animals.

Wildlife killing in Indonesia seems to be at an all-time high. In fact, a recent study published in the respected journal Conservation Biology indicates that on the island of Borneo, wildlife killing is now a bigger conservation threat than commercial logging.

Now such a statement is bound to generate a lot of derision. Many conservation organizations, scientists, as well as the government authorities will pooh-pooh the idea that hunting impacts are that disastrous. Why that is, I want to explore further.

But first, back to the study. The research, led by Jedediah Brodie of the University of British Columbia, deployed a series of camera traps across a gradient of disturbed areas to investigate direct and indirect impacts on wildlife. Although both hunting and new logging reduced the number of species in a given area, there was evidence that some wildlife eventually returned to selectively logged areas. This confirms analyses that my colleagues and I published in the Life after Logging book, several years ago.

The important finding is that the impacts of logging were relatively transient. Hunting pressure on the other hand was continual. Overall, hunting adversely impacted 87 percent of the species in the study.

These findings resonate with other hunting studies that I have conducted over the years on Borneo.

First, our Borneo-wide interview surveys conducted in 2009 suggested that thousands of orangutans are killed every year. More than half of the killings resulted in the orangutan being turned into a tasty steak or orangutan stew. The killing of orangutans happens both deep inside forests and in areas that are being deforested. Especially in areas where orangutans co-occurred with nomadic hunting tribes, the orangutan went extinct ages ago. So for orangutans, the picture that hunting is a bigger threat than logging seems well supported.

To get a better idea of the number of animals that are commonly affected through hunting, I conducted another study a few years ago. Every month for one year we gave 18 households in a Dayak village in East Kalimantan a calendar on which they could mark – with stickers – the different types of animals they had caught. After one year this amounted to 3,289 animals with a combined weight of 21,125 kg. The majority were bearded pigs (81 percent of total weight), deer (8 percent) and fish (6 percent). That’s about half a kilo of wildlife or fish per head of the population per day.

Now the total amount is a pretty meaningless number. What really matters is whether or not the take-off levels are sustainable. That is, can people keep harvesting at this level without species populations going extinct?

Problematically, almost no one is studying this. We can, however, get some idea about the answer when we talk to local communities. And their answer is pretty gloomy.

Pretty much any species they mention is considered to be in decline. There are fewer pigs, fewer deer, fewer monkeys, fewer orangutans, fewer fish, fewer snakes. Everything is going down. People are concerned about this, because today their meat is a free resource, but when that is gone they will have to start shopping in markets and for that they need cash. But despite their worries, no one is doing anything to change hunting habits.

Ever since I started talking to people in Kalimantan in the early 1990s about their hunting habits, I have been rather baffled by the fact that so few conservation-minded people in Indonesia show any interest in the topic, unless it concerns big conservation icons like tiger or rhino. If hunting is indeed such a big conservation problem, why are we not doing anything about it?

Part of the explanation is a belief held by many conservation advocates that the ‘traditional’ people of Borneo and other tropical forest areas somehow understand the concept of sustainable hunting levels. Trust me, they don’t.

If we want to maintain fish, bird and mammal populations that are big enough to feed people in perpetuity, they will have to change their hunting and fishing habits.

Laws about killing and harvesting endangered and commercially valuable species need to be enforced. Zero-hunting zones have to be established where wildlife populations can grow. Similar no-fishing zones have proven to be very effective, if indeed enforced rigorously.

And importantly, as long as wildlife is considered a resource owned by everyone, the ‘tragedy of the commons’ will apply: no one will bother to manage the resource because nobody feels ownership or responsibility.

The empty forest syndrome – standing trees without wildlife – is staring Indonesia into the face in pretty much all forests. Which conservation organizations and government authorities have the guts to stand up and do something about it?

Surely, for such apparent non-violent, non-confrontational and chilled-out people like Indonesians, it shouldn’t be too much of a burden to also extend that peace and love to its wildlife, right? After all, as Mahatma Gandhi said, “the greatness of a nation and its moral progress can be judged by the way its animals are treated.”

The Myth of Wildlife Overpopulation

http://foranimals.org/whats-left-for-wildlife/

What’s Left for Wildlife

The recent rushed passage of the National Defense Authorization Act with numerous anti-environmental riders exposes the sham of representative democracy. The Public Lands Council correctly describes the overwhelming vote for NDAA as clear case of Congress siding with ranchers. The act overturned grazing regulations which have been in effect over 30 years. Valles Caldera in northern New Mexico became a livestock operation funded by the National Park Service. As Congress would not dare to question, let alone defeat, a military appropriation, passage of this bill was a forgone conclusion. While a few liberal senators such as independent Bernie Sanders voted against the bill, the overwhelming majority of Democrats, including Elizabeth Warren, supported the military funding. Anti-environmental riders were of no concern to them.

Does the Democratic Party’s loss of the U.S. Senate mean anything for wildlife? Democratic Party support for the Keystone XL pipeline was the key to a failed attempt to keep control this year. It was a Democrat, Senator Jon Tester of Montana, who pioneered the practice of using riders to “must-pass” legislation to reverse decades of endangered species protection. With no significant opposition, Tester removed protection for wolves in the Northern Rockies, encouraging the Federal government to follow suit for other wolf populations. A recent court decision has temporarily reinstated protection for wolves in the Great Lakes region, but it remains to be seen if this decision will withstand appeal.

The legislative process is a competition of special interest groups, primarily funded by the wealthiest 1%. Lobbyists write legislation in closed-door committee meetings, which Congress rubber stamps with no meaningful discussion. Without a background in radical critiques of society, wildlife supporters know only liberal politics. Environmental and animal protection organizations, once based on grass-roots activism, are now merely insignificant lobbying organizations, whose primary purpose is raising funds for their own professional staff. Liberals challenge the National Rifle Association on gun control issues, but don’t seem to be aware that the NRA’s positions reflect its nature as a hunting organization. By working with so-called “hunter-conservationists,” environmental lobbyists legitimize the NRA agenda.

If there is anything more threatening to life on this planet than climate change it is nuclear war. Of course, New Mexico Senator Martin Heinrich, who has campaigned to increase hunting on Federal Lands, as well as supporting the Los Alamos nuclear lab, enthusiastically supported the military funding bill. It is particularly symbolic that the bill also included a national historic park commemorating the Manhattan Project, which launched the nuclear age. Perhaps we will someday see a national prehistoric park commemorating the discovery at Clovis of the weapons which launched the first anthropogenic mass extinction when humans arrived in the Americas during the Pleistocene.

The second anthropogenic mass extinction is now underway. In the latest Living Planet Index the World Wildlife Fund (WWF) estimates that over half of the population of wild vertebrates has disappeared in the last 40 years. Among the report’s conclusions: “The loss of habitat to make way for human land use – particularly for agriculture, urban development and energy production – continues to be a major threat to the terrestrial environment. When habitat loss and degradation is compounded by the added pressure of wildlife hunting, the impact on species can be devastating.”

International climate conferences are a sham, as debates focus only on how to raise money to help people adapt to inevitable climate change. There is no way to reverse climate change without drastically reducing the human population, an issue which liberal humanists ignore. The so-called radical left advocates “environmental justice” to help poor people adapt to climate change, while ignoring the destruction of wildlife habitat. Environmental justice for wildlife requires a movement to establish corridors to help wildlife adapt, as they once did when climate change occurred. Without a political left for wildlife there will be nothing at all left for wildlife.
