What do we lose when natural spaces and species disappear?

Increasingly, research has shown that as species and ecosystems vanish, it also chips away at our ability to preserve what remains — because we no longer understand what we're losing.

You probably see it all the time. The neighbor who puts pesticides on his lawn rather than deal with pesky bees. The kid who squirms and runs at the sight of a harmless garter snake slithering through the grass. The politician who votes against wildlife protection because she's never seen a wolf in the wild. The corporation that wants to bulldoze the habitat of a rare frog, but frogs are gross, so who cares, right?

At best this can be termed "the extinction of experience," where our cultural and natural histories fade from our memories and therefore our reality.

At its worst it becomes something even more concerning: "biophobia," the fear of living things and a complete aversion to nature.

This isn't the fiction of living in a cold, empty dystopia. Sadly it's becoming a way of life for too many people — especially children.

A recent study in Japan paints a striking portrait of this problem. A survey of more than 5,300 school children in the Tochigi Prefecture examined their perception of local invertebrates — 14 insect species and one spider. The results? A collective "ew." Most of the students saw the species as things to dislike, fear or abhor, or even as sources of danger. The less experience the students had with nature, the more negative their feelings.

The results were published earlier this year in the in the journal Biological Conservation.

Lead researcher Masashi Soga with the University of Tokyo says the study stemmed from observations about today's nature-deficient children.

"Humans inherently avoid dangerous organisms such as bees, but children these days avoid even harmless animals such as butterflies and dragonflies," he said. "I have long wondered why so many of today's children react like this."

Soga said their survey echoed findings from around the world. For example, a 2014 study of 1,100 students in China elicited similar emotional reactions — and, like the Japanese study, found that direct contact with nature helped to turn biophobia into biophilia, the term popularized by biologist E.O. Wilson to refer to human connection with other forms of life.

Although the children's reactions were somewhat expected, the new study did contain an unexpected finding: Many of the surveyed children revealed that their parents also expressed fear or disgust of the same invertebrates. In fact these parental emotions were strong enough to overwhelm any positive experiences the children might have gained from direct experiences in nature.

As Soga and his coauthors wrote in their paper, "Our results suggest that there is likely a feedback loop in which an increase in people who have negative attitudes towards nature in one generation will lead to a further increase in people with similar attitudes in the next generation — a cycle of disaffection towards nature."

And that's possibly the greater threat posed by extinction of experience. Soga suggests the generational loss — a condition previously dubbed environmental generational amnesia — could chip away at our societal ability to preserve what we're losing.

"I believe that increased biophobia is a major, but invisible, threat to global biodiversity," Soga said. "As the number of children who have biophobia increases, public interest and support for biodiversity conservation will gradually decline. Although many conservation biologists still consider that preventing the loss of wildlife habitat is the most important way to conserve biodiversity, I think preventing increased biophobia is also important for conservation."

What's to be done about this? The paper makes several recommendations, the most obvious of which is that children should experience nature more often. The authors also suggest establishing policies to guide these natural experiences and increasing educational programs about the natural world.

Helping parents to see species around them in a new light would make a difference, too.

And, of course, maintaining support for preserving the wild spaces where these "scary" and "icky" creatures live is the most important thing of all.

That's a point reinforced by another recent study, which found that wild spaces located within urban areas — and the plants and animals that thrive in them — are particularly important for human health and well-being.

Published in the journal Frontiers in Sustainable Cities, the study examined attitudes toward Discovery Park, the heavily forested 534-acre public park in Seattle, Washington. It found that the public had the most appreciation for — and gained the most value from — the wildest parts of the park.

"I have seen orca whales, seals, fish, eagles, herons, shorebirds and many other sea creatures in their natural habitat," one survey participant wrote. "Going here with people has allowed me to connect and talk with them about conversation that simply does not happen in everyday life," wrote another.

The participants reported that their most valuable experiences in the park included encountering wildlife, walking through open spaces, exploring the beach and finding beautiful views.

"We saw that a large majority of participants' interactions, especially their most meaningful interactions, depended on Discovery Park's relative wildness," said lead author Elizabeth Lev, a master's student in the University of Washington's Human Interaction With Nature and Technological Systems Lab.

This is only possible because the park is relatively wild. After all, you can't enjoy watching birds if there are no birds to follow; gaze at the sunset if it's obscured by skyscrapers; or stop and smell the flowers if they don't have room to grow.

And yet even this long-protected space could someday become less hospitable to nature. Over the past few years a lot of people and organizations have suggested developing parts of Discovery Park or the neighboring area. Most recently a plan proposed building 34 acres of much-needed affordable housing and parking spaces adjacent to the park, bringing with them noise, traffic and pollution.

If anything like that happened, both the park and the people of Seattle could lose something vital. And that would continue the trend of chipping away at Seattle's — and the world's — natural spaces, leaving just tiny pocket parks and green-but-empty spaces that offer little real value to wildlife, plants or people.

"It is true that any interaction with nature is better than none, but I don't want people to be satisfied with any small bit of grass and trees," Lev said. "We have been in this cycle of environmental generational amnesia for a long time, where the baseline keeps shifting and we don't even realize what we're losing until it's gone. If we can get people to understand how much meaning and value can come from having more experiences with more wild forms of nature, then maybe we can stop this cycle and move toward conserving and restoring what we have left."

Building this understanding in an ever-more fearful and disconnected world may be the biggest challenge. Peter Kahn, the senior author of Lev's paper and the director of the Human Interaction with Nature lab, made several suggestions for bridging this gap in this 2011 book, Technological Nature. They echo the recommendation about getting children into nature, but also include telling stories of how things used to be, imagining what things might be like in the future, and developing a common language about nature, "a way of speaking about wild and domestic interaction patterns, and their wide range of instantiations, and the meaningful, deep and often joyful feelings that they engender."

No matter what techniques we use, this growing field of research illustrates that saving nature requires encouraging people to experience it more often and more deeply. That calls for additional research — Lev and her coauthors have published a toolkit that other municipalities can follow to study the value of their own wild spaces — and clear communication of the results.

"If we can continue to characterize and show people the benefits of these wild spaces," Lev said, "maybe people will begin to see more value in keeping these areas undeveloped — for the sake of our mutual benefit."

Warming temperatures on land and in the water are already forcing many species to seek out more hospitable environments. Atlantic mackerel are swimming farther north; mountain-dwelling pikas are moving upslope; some migratory birds are altering the timing of their flights.

Numerous studies have tracked these shifting ranges, looked at the importance of wildlife corridors to protect these migrations, and identified climate refugia where some species may find a safer climatic haven.

"There's a huge amount of scientific literature about where species will have to move as the climate warms," says U.C. Berkeley biogeographer Matthew Kling. "But there hasn't been much work in terms of actually thinking about how they're going to get there — at least not when it comes to wind-dispersed plants."

Kling and David Ackerly, professor and dean of the College of Natural Resources at U.C. Berkeley, have taken a stab at filling this knowledge gap. Their recent study, published in Nature Climate Change, looks at the vulnerability of wind-dispersed species to climate change.

It's an important field of research, because while a fish can more easily swim toward colder waters, a tree may find its wind-blown seeds landing in places and conditions where they're not adapted to grow.

Kling is careful to point out that the researchers weren't asking how climate change was going to change wind; other research suggests there likely won't be big shifts in global wind patterns.

Instead the study involved exploring those wind patterns — including direction, speed and variability — across the globe. The wind data was then integrated with data on climate variation to build models trying to predict vulnerability patterns showing where wind may either help or hinder biodiversity from responding to climate change.

One of the study's findings was that wind-dispersed or wind-pollinated trees in the tropics and on the windward sides of mountain ranges are more likely to be vulnerable, since the wind isn't likely to move those dispersers in the right direction for a climate-friendly environment.

The researchers also looked specifically at lodgepole pines, a species that's both wind-dispersed and wind-pollinated.

They found that populations of lodgepole pines that already grow along the warmer and drier edges of the species' current range could very well be under threat due to rising temperatures and related climate alterations.

"As temperature increases, we need to think about how the genes that are evolved to tolerate drought and heat are going to get to the portions of the species' range that are going to be getting drier and hotter," says Kling. "So that's what we were able to take a stab at predicting and estimating with these wind models — which populations are mostly likely to receive those beneficial genes in the future."

That's important, he says, because wind-dispersed species like pines, willows and poplars are often keystone species whole ecosystems depend upon — especially in temperate and boreal forests.

And there are even more plants that rely on pollen dispersal by wind.

"That's going to be important for moving genes from the warmer parts of a species' range to the cooler parts of the species' range," he says. "This is not just about species' ranges shifting, but also genetic changes within species."

Kling says this line of research is just beginning, and much more needs to be done to test these models in the field. But there could be important conservation-related benefits to that work.

"All these species and genes need to migrate long distances and we can be thinking more about habitat connectivity and the vulnerability of these systems," he says.

The more we learn, the more we may be able to do to help species adapt.

"The idea is that there will be some landscapes where the wind is likely to help these systems naturally adapt to climate change without much intervention, and other places where land managers might really need to intervene," he says. "That could involve using assisted migration or assisted gene flow to actually get in there, moving seeds or planting trees to help them keep up with rapid climate change."

The last Ice Age eliminated some giant mammals, like the woolly rhino. Conventional thinking initially attributed their extinction to hunting. While overhunting may have contributed, a new study pinpointed a different reason for the woolly rhinos' extinction: climate change.

The last of the woolly rhinos went extinct in Siberia nearly 14,000 years ago, just when the Earth's climate began changing from its frozen conditions to something warmer, wetter and less favorable to the large land mammal. DNA tests conducted by scientists on 14 well-preserved rhinos point to rapid warming as the culprit, CNN reported.

"Humans are well known to alter their environment and so the assumption is that if it was a large animal it would have been useful to people as food and that must have caused its demise," says Edana Lord, a graduate student at the Center for Paleogenetics in Stockholm, Sweden, and co-first author of the paper, Smithsonian Magazine reported. "But our findings highlight the role of rapid climate change in the woolly rhino's extinction."

The study, published in Current Biology, notes that the rhino population stayed fairly consistent for tens of thousands of years until 18,500 years ago. That means that people and rhinos lived together in Northern Siberia for roughly 13,000 years before rhinos went extinct, Science News reported.

The findings are an ominous harbinger for large species during the current climate crisis. As EcoWatch reported, nearly 1,000 species are expected to go extinct within the next 100 years due to their inability to adapt to a rapidly changing climate. Tigers, eagles and rhinos are especially vulnerable.

The difference between now and the phenomenon 14,000 years ago is that human activity is directly responsible for the current climate crisis.

To figure out the cause of the woolly rhinos' extinction, scientists examined DNA from different rhinos across Siberia. The tissue, bone and hair samples allowed them to deduce the population size and diversity for tens of thousands of years prior to extinction, CNN reported.

Researchers spent years exploring the Siberian permafrost to find enough samples. Then they had to look for pristine genetic material, Smithsonian Magazine reported.

It turns out the wooly rhinos actually thrived as they lived alongside humans.

"It was initially thought that humans appeared in northeastern Siberia fourteen or fifteen thousand years ago, around when the woolly rhinoceros went extinct. But recently, there have been several discoveries of much older human occupation sites, the most famous of which is around thirty thousand years old," senior author Love Dalén, a professor of evolutionary genetics at the Center for Paleogenetics, said in a press release.

"This paper shows that woolly rhino coexisted with people for millennia without any significant impact on their population," Grant Zazula, a paleontologist for Canada's Yukon territory and Simon Fraser University who was not involved in the research, told Smithsonian Magazine. "Then all of a sudden the climate changed and they went extinct."

The environmental disaster that Mauritius is facing is starting to appear as its pristine waters turn black, its fish wash up dead, and its sea birds are unable to take flight, as they are limp under the weight of the fuel covering them. For all the damage to the centuries-old coral that surrounds the tiny island nation in the Indian Ocean, scientists are realizing that the damage could have been much worse and there are broad lessons for the shipping industry, according to Al Jazeera.

Transitioning to renewable energy can help reduce global warming, and Jennie Stephens of Northeastern University says it can also drive social change.

For example, she says that locally owned businesses can lead the local clean energy economy and create new jobs in underserved communities.

"We really need to think about … connecting climate and energy with other issues that people wake up every day really worried about," she says, "whether it be jobs, housing, transportation, health and well-being."

To maximize that potential, she says the energy sector must have more women and people of color in positions of influence. Research shows that leadership in the solar industry, for example, is currently dominated by white men.

"I think that a more inclusive, diverse leadership is essential to be able to effectively make these connections," Stephens says. "Diversity is not just about who people are and their identity, but the ideas and the priorities and the approaches and the lens that they bring to the world."

So she says by elevating diverse voices, organizations can better connect the climate benefits of clean energy with social and economic transformation.
