Noam Chomsky and Robert Pollin: If We Want a Future, Green New Deal Is Key
By C.J. Polychroniou
Climate change is by far the most serious crisis facing the world today. At stake is the future of civilization as we know it. Yet, both public awareness and government action lag way behind what's needed to avert a climate change catastrophe. In the interview below, Noam Chomsky and Robert Pollin discuss the challenges ahead and what needs to be done.
Noam Chomsky is Professor Emeritus of Linguistics at MIT and Laureate Professor of Linguistics at the University of Arizona. Robert Pollin is Distinguished University Professor of Economics and co-director of the Political Economy Research Institute at the University of Massachusetts at Amherst. Chomsky, Pollin and Polychroniou are co-authors of a book on climate change and the Green New Deal, forthcoming with Verso in Spring 2020.
C.J. Polychroniou: Noam, let me start with you and ask you to share your thoughts about the uniqueness of the climate change crisis.
Noam Chomsky: History is all too rich in records of horrendous wars, indescribable torture, massacres and every imaginable abuse of fundamental rights. But the threat of destruction of organized human life in any recognizable or tolerable form — that is entirely new. The environmental crisis under way is indeed unique in human history, and is a true existential crisis. Those alive today will decide the fate of humanity — and the fate of the other species that we are now destroying at a rate not seen for 65 million years, when a huge asteroid hit the earth, ending the age of the dinosaurs and opening the way for some small mammals to evolve to pose a similar threat to life on earth as that earlier asteroid, though differing from it in that we can make a choice.
Meanwhile the world watches as we proceed toward a catastrophe of unimaginable proportions. We are approaching perilously close to the global temperatures of 120,000 years ago, when sea levels were 6-9 meters higher than today. Glaciers are sliding into the sea five times faster than in the 1990s, with more than 100 meters of ice thickness lost in some areas due to ocean warming, and current losses doubling every decade. Complete loss of the ice sheets would raise sea levels by about five meters, drowning coastal cities, and with utterly devastating effects elsewhere — the low-lying plains of Bangladesh for example. This is only one of the many concerns of those who are paying attention to what is happening before our eyes.
Climate scientists are certainly paying close attention, and issuing dire warnings. Israeli climatologist Baruch Rinkevich captures the general mood succinctly:
After us, the deluge, as the saying goes. People don't fully understand what we're talking about here…. They don't understand that everything is expected to change: the air we breathe, the food we eat, the water we drink, the landscapes we see, the oceans, the seasons, the daily routine, the quality of life. Our children will have to adapt or become extinct…. That's not for me. I'm happy I won't be here.
Yet, just at the time when all must act together, with dedication, to confront humanity's "ultimate challenge," the leaders of the most powerful state in human history, in full awareness of what they are doing, are dedicating themselves with passion to destroying the prospects for organized human life.
With rare exceptions, the mainstream political establishment in the United States continues to look the other way when it comes to climate change. Why is that?
Chomsky: Both political parties have drifted right during the neoliberal years, much as in Europe. The Democratic establishment is now more or less what would have been called "moderate Republicans" some years ago. The Republicans have gone off the spectrum. Comparative studies show that they rank alongside of fringe rightwing parties in Europe in their general positions. They are, furthermore, the only major conservative party to reject anthropogenic climate change, as already mentioned: a global anomaly. Two respected political analysts of the American Enterprise Institute, Thomas Mann and Norman Ornstein, describe the Republican Party since Newt Gingrich's takeover in the '90s as not a normal political party but a "radical insurgency" that has largely abandoned parliamentary politics. Under McConnell's leadership, that has only become more evident — but he has ample company in Republican Party circles.
The positions of the leadership on climate surely influence the attitudes of Republican Party loyalists. Only about 25 percent of Republicans (36 percent of the more savvy millennials) recognize that humans are responsible for global warming. Shocking figures.
And in the ranking of urgent issues among Republicans, global warming (if it is even assumed to be taking place), is almost undetectable.
It is considered outrageous to assert that the Republican Party is the most dangerous organization in human history. Perhaps so, but in the light of the stakes, what else can one rationally conclude?
Bob, the Green New Deal is seen as perhaps the only viable solution to avert a climate change catastrophe of the sort described by Noam above, yet many continue to regard it as unrealistic, not only from a purely economic perspective (the claim is that it is simply unaffordable), but also in the sense that modern economies and societies cannot function without fossil fuel energy. First, is the Green New Deal a detailed policy proposal to move us away from a climate change catastrophe, and, second, is it realistic?
Robert Pollin: The Green New Deal has gained tremendous traction as an organizing framework over the past year. This alone is a major achievement. But it is still imperative that we transform this big idea into a viable program. In my view, putting meat on the bones of the Green New Deal starts with a single simple idea: We have to absolutely stop burning oil, coal and natural gas to produce energy within the next 30 years at most; and we have to do this in a way that also supports rising living standards and expanding opportunities for working people and the poor throughout the world.
This version of a Green New Deal program is, in fact, entirely realistic in terms of its purely economic and technical features. Clean renewable energy sources — including solar, wind, geothermal and to a lesser extent small-scale hydro and low emissions bioenergy — are already either at cost parity with fossil fuels and nuclear or they are cheaper. In addition, the single easiest and cheapest way to lower emissions is to raise energy efficiency standards, through, among other measures, retrofitting existing buildings; making new buildings operate as net zero energy consumers; and replacing gas-guzzler cars with expanding public transportation and electric cars. Energy efficiency measures, by definition, will save people money — for example, your home electricity bills could realistically be cut in half without having to reduce the amount that you light, heat or cool your house. So, the Green New Deal will not cost consumers anything over time, as long as we solve the actually quite simple problem of funding Green New Deal investments through the cost savings we gain by raising efficiency standards and producing cheap renewable energy. My coworkers and I have estimated that building a 100 percent clean energy system will require about 2.5 percent of global GDP per year for roughly the next 30 years. Yes, that's a lot of money in dollar terms, like about $2 trillion in 2021 and rising thereafter. But it does still mean that 97.5 percent of global economic activity can be devoted to things other than investments in clean energy.
So, absolutely, the Green New Deal can be a realistic global climate stabilization project. More specifically, the Green New Deal is capable of hitting the necessary emissions reduction targets for stabilization at a global average temperature of 1.5 degrees Celsius above pre-industrial levels by 2100, as set out by the Intergovernmental Panel on Climate Change (IPCC) last October. However, the real question, of course, is not whether the Green New Deal is economically or technically feasible, but rather whether it is politically feasible. On this question, Noam is of course exactly on point in asking: Are we, the human race, going to allow ourselves to become the 21st-century asteroid clone or not?
What about the claim that a transition to 100 percent renewable energy will result in the permanent loss of millions of good-paying jobs?
Pollin: In fact, clean energy investments will be a major source of new job creation, in all regions of the globe. The critical factor is that clean energy investments will create a lot more jobs than maintaining the existing dirty energy infrastructure — in the range of two to four times more jobs per dollar of spending in all countries that we have studied, including Brazil, China, India, Indonesia, South Africa, Spain and the United States. Of course, jobs that are tied to the fossil fuel industry will be eliminated. The affected workers and their communities must be supported through generous Just Transition measures, including guaranteeing workers' pensions, moving people into new jobs without losing incomes, and investing in impacted communities, in a range of projects. Land reclamation is just one such investment opportunity, including cleaning up abandoned coal mines and converting the residual coal ash into useful products, like paper. I can't emphasize enough that, throughout the world, "just transition" programs must be understood as absolutely central to the Green New Deal.
Noam, how do we increase public awareness about the need for government action vis-à-vis climate change?
Chomsky: The simple answer is: work harder. There are no new special tricks. We know what the message is. We know the barriers that have to be overcome. We have to find ways to shape the message, in words and actions, so as to overcome the barriers.
The message is two-fold: First, we're facing an existential crisis that must be dealt with quickly; and second, there are ways to overcome it.
The first part is expressed simply enough in current articles in the most prestigious and reliable journals. Oxford professor of physics Raymond Pierrehumbert, a lead author of the recent IPCC report, opens his review of existing circumstances and options by writing: "Let's get this on the table right away, without mincing words. With regard to the climate crisis, yes, it's time to panic…. We are in deep trouble." He then lays out the details carefully and scrupulously, reviewing the possible technical fixes and their very serious problems, concluding, "There's no plan B." We must move to zero net carbon emissions, and fast.
The second part is spelled out in convincing detail in Bob's work, briefly reviewed here.
The message must be conveyed in ways that do not induce despair and resignation among those inclined to accept it, and do not evoke resentment, anger and even greater rejection among those who do not accept what is in fact becoming overwhelmingly clear.
In the latter case, it is necessary to understand the reasons — perhaps rejection of science altogether, or adopting economists' preference for market-based solutions which, whatever one thinks of them, are completely on the wrong time-scale, or the great many who expect the Second Coming, or those who think we will be rescued by some unknown technology or great figure, perhaps the colossus perceived by scholars at Stanford University's Hoover Institution, whose "spirit seems to stride the country, watching us like a warm and friendly ghost" (Ronald Reagan).
The task will not be easy. It must be undertaken, urgently. By words and by actions, such as those being undertaken in the climate strikes of September 2019.
Bob, what will it take for the labor movement as a whole to come around and embrace the Green New Deal vision?
Pollin: The Green New Deal has been gaining major support in the labor movement for several years now. There is still a long way to go, but progress is evident. For example, the coalition in Washington State that advanced a Green New Deal proposition in the 2018 election cycle was led by the visionary then president of the state AFL-CIO, Jeff Johnson. In the end, the initiative was defeated when oil companies flooded the airwaves with $30 million of virulent propaganda in the weeks before the November election. Similar initiatives are now being advanced in Colorado, again led by the state's mainstream labor leaders.
Of course, we need to very quickly advance beyond just these few shining examples. What is critical here is that the climate movement must be firmly committed to a just transition as one component of the Green New Deal that is of equal significance with all the others. The climate movement needs to also be clear on the point that building the clean energy economy will be supportive of increasing job opportunities and rising living standards, as I am convinced it can be.
There is no reason that the Green New Deal needs to be associated with austerity economic policies in any way. To the contrary, clean energy investments will create new opportunities for a wide range of small-scale public, cooperative, and private ownership forms. You don't need massive mining projects, pipelines or exploration platforms to deliver clean energy. Solar panels on roofs and in parking lots and wind turbines on farms can, by themselves, get us reasonably far along in meeting the energy needs of a growing egalitarian economy. From this perspective, the Green New Deal should rightfully be seen as offering a fully viable alternative to austerity economics along with the only realistic path for keeping us from becoming the 21st-century asteroid clone.

As Biden Embraces More Ambitious Climate Plan, Fossil Fuel Execs Donate to Trump 'With Greater Zeal' Than in 2016
By Jake Johnson
With presumptive Democratic nominee Joe Biden's climate platform becoming increasingly ambitious thanks to nonstop grassroots pressure, fossil fuel executives and lobbyists are pouring money into the coffers of President Donald Trump's reelection campaign in the hopes of keeping an outspoken and dedicated ally of dirty energy in the White House.

While the nation overall struggles with rising COVID cases, New York State is seeing the opposite. After peaking in March and April and implementing strict shutdowns of businesses, the state has seen its number of positive cases steadily decline as it slowly reopens. From coast-to-coast, Governor Andrew Cuomo's response to the crisis has been hailed as an exemplar of how to handle a public health crisis.

Sharks elicit outsized fear, even though the risk of a shark bite is infinitesimally small. As a marine biologist and director of the Florida Program for Shark Research, I oversee the International Shark Attack File – a global record of reported shark bites that has been maintained continuously since 1958.
A Big, Diverse Family<p>Not all sharks are the same. Only a dozen or so of the roughly 520 shark species pose any risk to people. Even the three species that account for almost all shark bite fatalities – the <a href="https://www.floridamuseum.ufl.edu/discover-fish/species-profiles/carcharodon-carcharias/" target="_blank">white shark</a> (<em>Carcharodon carcharias</em>), <a href="https://www.floridamuseum.ufl.edu/discover-fish/species-profiles/galeocerdo-cuvier/" target="_blank">tiger shark</a> (<em>Galeocerdo cuvier</em>) and <a href="https://www.floridamuseum.ufl.edu/discover-fish/species-profiles/carcharhinus-leucas/" target="_blank">bull shark</a> (<em>Carcharhinus leucas</em>) – are behaviorally and evolutionarily very different from one another.</p><p>The tiger shark and bull shark are genetically as different from each other as a dog is from a rabbit. And both of these species are about as different from a white shark as a dog is from a kangaroo. The evolutionary lineages leading to the two groups split 170 million years ago, during the age of dinosaurs and before the origin of birds, and <a href="https://www.ck12.org/book/CK-12-Human-Biology/section/7.2/" target="_blank">110 million years before the origin of primates</a>.</p>
White, tiger and bull sharks are distinct species that diverged genetically tens of millions of years ago. Gavin Naylor / CC BY-ND<p>Yet many people assume all sharks are alike and equally likely to bite humans. Consider the term "shark attack," which is scientifically equivalent to "mammal attack." Nobody would equate dog bites with hamster bites, but this is exactly what we do when it comes to sharks.</p><p>So, when a reporter calls me about a fatality caused by a white shark off Cape Cod and asks my advice for beachgoers in North Carolina, it's essentially like asking, "A man was killed by a dog on Cape Cod. What precautions should people take when dealing with kangaroos in North Carolina?"</p>
Know Your Species<p>Understanding local species' behavior and life habits is one of the best ways to stay safe. For example, almost all shark bites that occur off Cape Cod are by white sharks, which are a large, primarily cold-water species that spend most of their time in isolation feeding on fishes. But they also aggregate near seal colonies that provide a reliable food source at certain times of the year.</p><p>Shark bites in the Carolinas are by warm-water species like bull sharks, tiger sharks and <a href="https://www.floridamuseum.ufl.edu/discover-fish/species-profiles/carcharhinus-limbatus/" target="_blank">blacktips</a> (<em>Carcharhinus limbatus</em>). Each species is associated with particular habitats and dietary preferences.</p><p>Blacktips, which we suspect are responsible for most relatively minor bites on humans in the southeastern United States, feed on schooling bait fishes like menhaden. In contrast, bull sharks are equally at home in fresh water and salt water, and are often found near estuaries. Their bites are more severe than those of blacktips, as they are larger, more powerful, bolder and more tenacious. Several fatalities have been ascribed to bull sharks.</p><p>Tiger sharks are also large, and are responsible for a significant fraction of fatalities, particularly off the coast of volcanic islands like Hawaii and Reunion. They are tropical animals that often venture into shallow water frequented by swimmers and surfers.</p>

Humans Are Not Targets<p>Sharks do not "hunt" humans. Data from the International Shark Attack File compiled over the past 60 years show a tight association between shark bites and the number of people in the water. In other words, shark bites are a simple function of the probability of encountering a shark.</p><p>This underscores the fact that shark bites are almost always cases of mistaken identity. If sharks actively hunted people, there would be many more bites, since humans make very easy targets when they swim in sharks' natural habitats.</p><p>Local conditions can also affect the risk of an attack. Encounters are more likely when sharks venture closer to shore, into areas where people are swimming. They may do this because they are following bait fishes or seals upon which they prey.</p><p>This means we can use environmental variables such as temperature, tide or weather conditions to better predict movement of bait fish toward the shoreline, which in turn will predict the presence of sharks. Over the next few years, the Florida Program for Shark Research will work with colleagues at other universities to monitor onshore and offshore movements of tagged sharks and their association with environmental variables so that we can improve our understanding of what conditions bring sharks close to shore.</p>
More to Know<p>There still is much to learn about sharks, especially the 500 or so species that have never been implicated in a bite on humans. One example is the tiny <a href="https://www.newsweek.com/one-worlds-rarest-sharks-also-one-most-adorable-325280" target="_blank">deep sea pocket shark</a>, which has a strange pouch behind its pectoral fins.</p><p>Only two specimens of this type of shark have ever been caught – one off the coast of Chile 30 years ago, and another more recently in the Gulf of Mexico. We're not sure about the function of the pouch, but suspect it stores luminous fluid that is released to distract would-be predators – much as its close relative, the <a href="https://sharkdevocean.wordpress.com/2015/04/23/second-ever-pocket-shark-discovered-in-gulf-of-mexico/" target="_blank">tail light shark</a>, releases luminous fluid from a gland on its underside near its vent.</p>

Although whale sharks are the largest fishes in the world, we have yet to locate their nursery grounds, which are likely teeming with thousands of <a href="https://www.earthtouchnews.com/oceans/sharks/baby-whale-shark-rescued-from-gillnet-in-india-video/" target="_blank">foot-long pups</a>. Some deepwater sharks are primarily known from submersibles, such as the giant <a href="https://twitter.com/gavinnaylor/status/1146144452681113601" target="_blank">sixgill shark</a>, which feeds mainly on carrion but probably also preys on other animals in the deep sea.</p><p>Sharks seem familiar to almost all of us, but we know precious little about them. Our current understanding of their biology barely scratches the surface. The little we do know suggests they are profoundly different from other vertebrate animals. They've had 400 million years of independent evolution to adapt to their environments, and it's reasonable to expect they may be hiding more than a few tricks up their gills.</p>

Known and anticipated changes in species distribution due to climate change around the world have implications for culture, society ecosystems, governance and climate change. Figure used with permission from Gretta T. Pecl, originally published on 31 Mar 2017 in Science 355(6332).<p>How we define species is critical, because these definitions influence perceptions, policy and management. The U.S. National Invasive Species Council (NISC) defines a biological invasion as "the process by which non-native species breach biogeographical barriers and extend their range" and states that "preventing the introduction of potentially harmful organisms is … the first line of defense." But some say excluding newcomers is myopic.</p><p>"If you were trying to maintain the status quo, so every time a new species comes in, you chuck it out," says Camille Parmesan, director of the French National Centre for Scientific Research, you could gradually "lose so many that that ecosystem will lose its coherence." If climate change is driving native species extinct, she says, "you need to allow new ones coming in to take over those same functions."</p><p>As University of Florida conservation ecologist Brett Scheffers and Pecl warned in a <a href="https://www.nature.com/articles/s41558-019-0526-5" target="_blank">2019 paper in <em>Nature Climate Change</em></a>, "past management of redistributed species … has yielded mixed actions and results." They concluded that "we cannot leave the fate of biodiversity critical to human survival to be randomly persecuted, protected or ignored."</p>
Existing Tools<p>One approach to managing these climate-driven habitat shifts, suggested by University of California, Irvine marine ecologist Piper Wallingford and colleagues in <a href="https://www.nature.com/articles/s41558-020-0768-2" target="_blank">a recent issue of Nature Climate Change</a>, is for scientists to adapt existing tools like the <a href="https://www.iucn.org/theme/species/our-work/invasive-species/eicat" target="_blank">Environmental Impact Classification of Alien Taxa (EICAT)</a> to assess potential risks associated with moving species. Because range-shifting species pose impacts to communities similar to those of species introduced by humans, the authors argue, new management strategies are unnecessary, and each new arrival can be evaluated on a case-by-case basis.</p><p>Karen Lips, a professor of biology at University of Maryland who was not associated with the study, echoes the idea that each case is so varied and nuanced that trying to fit climate shifting species into a single category with broad management goals may be impractical. "Things may be fine today, but add a new mosquito vector or add a new tick or a new disease, and all of a sudden things spiral out of control," she says. "The nuance means that the answer to any particular problem might be pretty different."</p>
In recent years, northern flying squirrels in Canada have found themselves in the company of new neighbors — southern flying squirrels expanding their range as the climate warms. Public Domain / USFW<p>Laura Meyerson, a professor in the Department of Natural Resources Science at the University of Rhode Island says scientists should use existing tools to identify and address invasive species to deal with climate-shifting species. "I would like to operate under the precautionary principle and then reevaluate as things shift. You're sort of shifting one piece in this machinery; as you insert a new species into a system, everything is going to respond," she says. "Will some of the species that are expanding their ranges because of climate change become problematic? Perhaps they might."</p><p>The reality is that some climate-shifting species may be harmful to some conservation or economic goals while being helpful to others. While sport fisherman are excited about red snapper moving down the East Coast of Australia, for example, if they eat juvenile lobsters in Tasmania they could harm this environmentally and economically important crustacean. "At the end of the day … you're going to have to look at whether that range expansion has some sort of impact and presumably be more concerned about the negative impacts," says NISC executive director Stas Burgiel. "Many of the [risk assessment] tools we have are set up to look at negative impact." As a result, positive effects may be deemphasized or overlooked. "So that notion of cost versus benefit … I don't think it has played out in this particular context."</p>
Location, Location, Location<p>In a <a href="https://www-nature-com.ezp3.lib.umn.edu/articles/s41558-020-0770-8" target="_blank">companion paper</a> to Wallingford's, University of Connecticut ecology and evolutionary biology associate professor Mark Urban stressed key differences between invasive species, which are both non-native and harmful, and what he calls "climate tracking species." Whereas invasive species originate from places very unlike the communities they overtake, he says, climate tracking species expand from largely similar environments, seeking to follow preferred conditions as these environments move. For example, an American pika may relocate to a higher mountain elevation, or a marbled salamander might expand its New England range northward to seek cooler temperatures, but these new locations are not drastically different than the places they had called home before.</p><p>Climate tracking species may move faster than their competitors at first, Urban says, but competing species will likely catch up. "Applying perspectives from invasion biology to climate-tracking species … arbitrarily chooses local winners over colonizing losers," he writes.</p>
The marbled salamander, a native of the eastern U.S., is among species whose range could expand northward to accommodate rising temperatures. Seánín Óg / Flickr / CC BY-NC-ND 2.0<p>Urban stresses that if people prevent range shifts, some climate-tracking species may have nowhere to go. He suggests that humans should even <a href="https://ensia.com/features/time-for-trees-to-pack-their-trunks/" target="_blank">facilitate movement</a> as the planet warms. "The goal in this crazy warming world is to keep everything alive. But it may not be in the same place," Urban says.</p><p>Parmesan echoes Urban, emphasizing it's the distance that makes the difference. "[Invasives] come from a different continent or a different ocean. You're having these enormous trans-global movements and that's what ends up causing the species that's exotic to be invasive," she says. "Things moving around with climate change is a few hundred miles. Invasive species are moving a few thousand miles."</p><p>In 2019 University of Vienna conservation biology associate professor Franz Essl published a similar argument for species classification beyond the native/non-native dichotomy. Essl uses "neonatives" to refer to species that have expanded outside their native areas and established populations because of climate change but not direct human agency. He argues that these species should be considered as native in their new range.</p>
They Never Come Alone<p>Meyerson calls for caution. "I don't think we should be introducing species" into ecosystems, she says. "I mean, they never come alone. They bring all their friends, their microflora, and maybe parasites and things clinging to their roots or their leaves. … It's like bringing some mattress off the street into your house."</p><p>Burgiel warns that labeling can have unintended consequences. We in the invasive species field … focus on non-native species that cause harm," he says. "Some people think that anything that's not native is invasive, which isn't necessarily the case." Because resources are limited and land management and conservation are publicly funded, Burgiel says, it is critical that the public understands how the decisions are being made.</p><p>Piero Genovesi, chair of the International Union for the Conservation of Nature's Invasive Species Specialist Group, sees the debate about classification — and therefore about management — as a potential distraction from more pressing conservation issues.</p><p>"The real bulk of conservation is that we want to focus on the narrow proportion of alien species that are really harmful," he says. In Hawaii "we don't discuss species that are there [but aren't] causing any problem because we don't even have the energy for dealing with them all. And I can tell you, no one wants to remove [non-native] cypresses from Tuscany. So, I think that some of the discussions are probably not so real in the work that we do in conservation."</p><p>Indigenous frameworks offer another way to look at species searching for a new home in the face of climate change. According to <a href="https://link.springer.com/article/10.1007%2Fs11625-018-0571-4" target="_blank">a study</a> published in Sustainability Science in 2018 by Dartmouth Native American studies and environmental studies associate professor Nicholas Reo, a citizen of the Sault Ste. Marie Tribe of Chippewa Indians, and Dartmouth anthropology associate professor Laura Ogden, some Anishnaabe people view plants as persons and the arrival of new plants as a natural form of migration, which is not inherently good or bad. They may seek to discover the purpose of new species, at times with animals as their teachers. In their paper Reo and Ogden quote Anishnaabe tribal chairman Aaron Payment as saying, "We are an extension of our natural environment; we're not separate from it."</p>
The Need for Collaboration<p>The successful conservation of Earth's species in a way that keeps biodiversity functional and healthy will likely depend on collaboration. Without global agreements, one can envision scenarios in which countries try to impede high-value species from moving beyond their borders, or newly arriving species are quickly overharvested.</p><p>In Nature Climate Change, Sheffers and Pecl call for a Climate Change Redistribution Treaty that would recognize species redistribution beyond political boundaries and establish governance to deal with it. Treaties already in place, such as the Convention on International Trade in Endangered Species of Wild Fauna and Flora, which regulates trade in wild plants and animals; the Migratory Bird Treaty Act; and the Agreed Measures for the Conservation of Antarctic Fauna and Flora, can help guide these new agreements.</p><p>"We are living through the greatest redistribution of life on Earth for … potentially hundreds of thousands of years, so we definitely need to think about how we want to manage that," Pecl says.</p><p>Genovesi agrees that conservationists need a vision for the future. "What we do is more to be reactive [to known threats]. … It's so simple to say that destroying the Amazon is probably not a good idea that you don't need to think of a step ahead of that." But, he adds, "I don't think we have a real answer in terms of okay, this is a threshold of species, or this is the temporal line where we should aim to." Defining a vision for what success would look like, Genovesi says, "is a question that hasn't been addressed enough by science and by decision makers."</p><p>At the heart of these questions are values. "All of these perceptions around what's good and what's bad, all [are based on] some kind of value system," Pecl says. "As a whole society, we haven't talked about what we value and who gets to say what's of value and what isn't."</p><p>This is especially important when it comes to marginalized voices, and Pecl says she is concerned because she doesn't "think we have enough consideration or representation of Indigenous worldviews." Reo and colleagues <a href="https://cpb-us-e1.wpmucdn.com/sites.dartmouth.edu/dist/9/52/files/2012/10/Reo_etal_AIQ_invasive_species_2017.pdf" target="_blank">wrote in American Indian Quarterly in 2017</a> that climate change literature and media coverage tend to portray native people as vulnerable and without agency. Yet, says Pecl, "The regions of the world where [biodiversity and ecosystems] are either not declining or are declining at a much slower rate are Indigenous controlled" — suggesting that Indigenous people have potentially managed species more effectively in the past, and may be able to manage changing species distributions in a way that could be informative to others working on these issues.</p><p>Meanwhile, researchers such as Lips see species classification as native or other as stemming from a perspective that there is a better environmental time and place to return to. "There is no pristine, there's no way to go back," says Lips. "The entire world is always very dynamic and changing. And I think it's a better idea to consider just simply what is it that we do want, and let's work on that."</p>
