Sustainable New Urban Mobility
Raising Greenagers
What inspires teens to think and act green? As the mother of a
current teen and two former ones, I still wrestle at times with that question.
I’ve
found that most teens want to do the right thing. Although they may be
great at hiding it, they really do look to their parents and other
influential adults for guidance.
The
teen years are about developing a separate and unique identity from
parents. A challenge faced by parents and other caregivers is how best
to connect with teenagers in ways that recognize their need for
autonomy while guiding them towards becoming environmentally-responsible
and mindful adults.
Below are some ideas for getting there.
 Generation Z
Today’s teens are members of Generation Z. Born after 1995, they represent about 25% of the U.S. population. Recent
research has shown that they are pragmatic, digitally
hyper-connected, and informed. They are also socially-conscious and
entrepreneurial, say researchers.
Be a Model. “The
biggest way to demonstrate the importance to your teens of living green is to
model good behavior at home,” noted my former colleague, Jeff. He added, “It’s also important is to make
sure you get involved in issues and programs in your community.”
In Jeff’s case, that meant stepping up to serve as advisor
for his daughter’s initiative, a high school environmental club, until suitable
school staff could take over. “Through my guidance, they were able to
accomplish a lot of great things at their school and received a lot of
recognition, including scholarships,” he said.
Look for opportunities at
home to foster your teen’s green
side. For example, involve them in brainstorming ways to reduce
household and personal energy and water use. Tap into their entrepreneurial side by challenging
them to come up with ideas for new green businesses or for greening existing
businesses they care about.

Encourage
Volunteerism. “Service and volunteering is increasingly a big deal for
teens. It’s something that they know is important, for example, on college
applications,” said Kevin McDonald, a father of two teens.
Indeed, the research confirms Kevin’s observation. A 2014 study
found 77% of high school students on a national level either extremely or very
interested in volunteering. The top three things they reported wanting to
get out of it were new skills, work experience, and mentorship/networking.
At VolunteerMatch.org,
teens and adults can search for volunteering opportunities based on location
and interest area. A recent search
turned up 60 environment-related opportunities in the Twin Cities area. Hands
on Twin Cities is another good source.
The organization DoSomething.org inspires teens to volunteer and take action on causes they care about by
providing a ton of fun project ideas and information.
Conservation
Corps Minnesota & Iowa offers a few different environment-related
service programs for teens age 15-18. Teens in one such program, Youth
Outdoors, participate in environmental restoration projects within the Twin
Cities. Teens 18 and over are eligible to serve as AmeriCorps members in a
variety of settings.
Citizen
science provides teens with an opportunity to combine volunteerism and the great outdoors. See Living Green 365: Citizen Science for resources and information.
Lastly, check with schools, nature centers, park and rec
departments, local nonprofits, and local government offices for leads and
information on volunteering. Earth Day, Arbor Day, and similar events often provide many volunteering opportunities. High
school environmental clubs like the one that Jeff’s daughter started are
another good option.
Additional Resource: WaysToHelp.org exists to engage, inspire and enable high school students to make a
positive difference in the world. It does this by making it easy for
them to learn about, and take action on, sixteen of today's most
pressing social issues as well as providing teens & schools with
toolkits to improve in-school food and volunteer drives.
WaysToHelp.org offers grants (up to $500) to teens in the U.S. to to fund their community service ideas across any one of 16
issue areas, including clean water, land preservation, global warming
and recycling.

Expose them to
Nature. Exposure to nature can result in a lifelong interest in environmental protection and
conservation.
Invite
your teen to go on nature walks and hikes, biking, camping,
fishing, canoeing, and similar. Involve them in planning outdoor
activities
that the family can do together. Need to sweeten the deal to gain your
teen’s participation? Encourage/allow her to invite a friend along.
For additional inspiration and ideas, check out familiesoutdoors.org.
Encourage biking/walking. For
many teens, learning to drive a car is a rite of passage. Parents may
find themselves under increased pressure to hand over the keys.
Chat with your teen about the environmental impacts of driving. Encourage him to bike or walk to activities and places
that are within a reasonable distance. Teach her how to take the bus or other means
of public transportation (for the Twin Cities area, click on "How to Ride" at metrotransit.org).
Consider meeting your teen halfway when the opportunity arises. “I told
my 15 year old son that I would buy him any bike that he wanted, an IPhone 6,
and a bus pass if he would agree to wait until he’s 18 to get his driver’s
license,” said Ned. Given the costs of insurance, gas, vehicle wear and tear,
and the many environmental impacts of driving, this type of “negotiated
settlement” can potentially be a win-win.
|
Plug into their
digital world. Smartphones. Gaming systems. Tablets. Laptops. Teens
love their gadgets, and being “connected” is virtually a requirement anymore. Unfortunately,
the same devices that they adore can be huge energy wasters.
Lots of devices use power even when they’re in standby mode. Ask your
teen to unplug her digital devices—and their cords—when they’re
done charging. Where possible, install advanced
(aka smart) power strips in your home.
Other ideas:
|
Get Loud. Has your teen heard
of the "Get Loud" competition? It's a joint effort of NextGen Climate
America and the Alliance for Climate Education to engage and empower
young Americans
to take civic action online and in their communities to combat climate
change.Teens earn points and potential prizes by taking highly-visible
online and offline actions, sharing content, and recruiting other teens
to participate.
Listen, Acknowledge,
Engage, and Empower. One of the great things about teens is that they’re
not yet adults. They are still forming opinions and behaviors and absorbing
information that will guide them in their adult years.
“Teens
are sensitive about the increasing amount of news regarding the potential for
environmental collapse”, said Kevin. " They can find it overwhelming and depressing," he added.
Yet, says Kevin, it's still important to talk with teenagers about environmental issues, even if it's in small bites.
Look
for opportunities to engage them in
conversations about environmental topics and issues. Ask for their
opinions and
ideas. Encourage them to be creative problem-solvers. Point out how
personal choices (purchasing, transportation, energy use) can have an
impact, and what they can do to make a difference.
Looking for guidance? The Alliance for Climate Education offers parents and educators some excellent resources for talking with adolescents about climate change.
DoingGoodTogether.org has activities, book lists, and
discussion questions for families. For their earth-themed list see http://www.doinggoodtogether.org/bhf/heal-the-earth.
Additional Resource: Consume This - Buying That Matters. This 40-page booklet from the Canadian Centre for Pollution Prevention
is aimed at 14- to 18-year-olds. The information and resources provided
in the booklet focus on sustainable consumption and help to raise
awareness among youth about the effects that their choices have on the
environment.
Issues addressed in the booklet—including resource
conservation, consumer behavior, and environmentally friendly production—are presented
in a manner relevant to teens. Examples such
as "The Life-Cycle of a T-Shirt", "What's in a Soccer Ball", and "How to
Pack a Litterless Lunch" introduce young people to the concept of

Permaculture Fundamentals Cards
"All 21 cards of the Mollison Permaculture Ethics and Design Principles card set are now free to download from <www.permaculturefundamentals.com/>.
These are the original permaculture ethics and design principles from
the writings of Bill Mollison, the father of permaculture and developer
of the Permaculture Design Certificate (PDC).
I first taught the PDC in
1993, and this arrangement of the original ethics and principles from
Permaculture: A Designers' Manual (Mollison 1988) and Introduction to
Permaculture (Mollison and Slay 1992) came about after many years
teaching permaculture and running permaculture projects. The cards are
organised into ethics, energy principles, component placement
principles, principles from nature, and attitudinal principles. It is
these attitudinal principles, which along with the ethics are the
'heart and soul' of permaculture, that are often missing from condensed
versions of the permaculture principles. The cards are designed to be
printed as 6x4 photos, as this is often the cheapest form of high
quality printing if you only want a small print run."

How Nature Can Make You Kinder, Happier, and More Creative
By Jill Suttie
We are spending more time indoors and
online. But recent studies suggest that nature can help our brains and
bodies to stay healthy.
I’ve been an avid hiker my whole life. From the time I first
strapped on a backpack and headed into the Sierra Nevada Mountains, I
was hooked on the experience, loving the way being in nature cleared my
mind and helped me to feel more grounded and peaceful.
But, even though I’ve always believed
that hiking in nature had many psychological benefits, I’ve never had
much science to back me up…until now, that is. Scientists are beginning
to find evidence that being in nature has a profound impact on our
brains and our behavior, helping us to reduce anxiety, brooding, and
stress, and increase our attention capacity, creativity, and our ability
to connect with other people.
“People have been discussing their profound experiences in nature for
the last several 100 years—from Thoreau to John Muir to many other
writers,” says researcher David Strayer, of the University of Utah. “Now
we are seeing changes in the brain and changes in the body that suggest
we are physically and mentally more healthy when we are interacting
with nature.”
While he and other scientists may believe nature benefits our
well-being, we live in a society where people spend more and more time
indoors and online—especially children. Findings on how nature improves
our brains brings added legitimacy to the call for preserving natural
spaces—both urban and wild—and for spending more time in nature in order
to lead healthier, happier, and more creative lives.
Here are some of the ways that science is showing how being in nature affects our brains and bodies.
1. Being in nature decreases stress
It’s clear that hiking—and any physical activity—can reduce stress
and anxiety. But, there’s something about being in nature that may
augment those impacts.
In one recent experiment
conducted in Japan, participants were assigned to walk either in a
forest or in an urban center (taking walks of equal length and
difficulty) while having their heart rate variability, heart rate, and
blood pressure measured. The participants also filled out questionnaires
about their moods, stress levels, and other psychological measures.
Results showed that those who walked in forests had significantly
lower heart rates and higher heart rate variability (indicating more
relaxation and less stress), and reported better moods and less anxiety,
than those who walked in urban settings. The researchers concluded that
there’s something about being in nature that had a beneficial effect on
stress reduction, above and beyond what exercise alone might have
produced.
In another study,
researchers in Finland found that urban dwellers who strolled for as
little as 20 minutes through an urban park or woodland reported
significantly more stress relief than those who strolled in a city
center.
The reasons for this effect are unclear; but scientists believe that we evolved to be more relaxed in natural spaces. In a now-classic laboratory experiment
by Roger Ulrich of Texas A&M University and colleagues,
participants who first viewed a stress-inducing movie, and were then
exposed to color/sound videotapes depicting natural scenes, showed much
quicker, more complete recovery from stress than those who’d been
exposed to videos of urban settings.
These studies and other provide evidence that being in natural spaces— or even just looking out of a window onto a natural scene—somehow soothes us and relieves stress.
2. Nature makes you happier and less brooding
I’ve always found that hiking in nature makes me feel happier, and of
course decreased stress may be a big part of the reason why. But,
Gregory Bratman, of Stanford University, has found evidence that nature
may impact our mood in other ways, too.
In one 2015 study,
he and his colleagues randomly assigned 60 participants to a 50- minute
walk in either a natural setting (oak woodlands) or an urban setting
(along a 4-lane road). Before and after the walk, the participants were
assessed on their emotional state and on cognitive measures, such as how
well they could perform tasks requiring short-term memory. Results
showed that those who walked in nature experienced less anxiety,
rumination (focused attention on negative aspects of oneself), and
negative affect, as well as more positive emotions, in comparison to the
urban walkers. They also improved their performance on the memory
tasks.
In another study, he and his colleagues extended these findings
by zeroing in on how walking in nature affects rumination— which has
been associated with the onset of depression and anxiety—while also
using fMRI technology to look at brain activity. Participants who took a
90-minute walk in either a natural setting or an urban setting had
their brains scanned before and after their walks and were surveyed on
self-reported rumination levels (as well as other psychological
markers). The researchers controlled for many potential factors that
might influence rumination or brain activity—for example, physical
exertion levels as measured by heart rates and pulmonary functions.
Even so, participants who walked in a natural setting versus an urban
setting reported decreased rumination after the walk, and they showed
increased activity in the subgenual prefrontal cortex, an area of the
brain whose deactivation is affiliated with depression and anxiety—a
finding that suggests nature may have important impacts on mood.
Bratman believes results like these need to reach city planners and
others whose policies impact our natural spaces. “Ecosystem services
are being incorporated into decision making at all levels of public
policy, land use planning, and urban design, and it’s very important to
be sure to incorporate empirical findings from psychology into these
decisions,” he says.

Today, we live with ubiquitous technology designed to constantly pull
for our attention. But many scientists believe our brains were not made
for this kind of information bombardment, and that it can lead to
mental fatigue, overwhelm, and burnout, requiring “attention
restoration” to get back to a normal, healthy state.
Strayer is one of those researchers, at the University of Utah. He
believes that being in nature restores depleted attention circuits,
which can then help us be more open to creativity and problem-solving.
“When you use your cell phone to talk, text, shoot photos, or
whatever else you can do with your cell phone, you’re tapping the
prefrontal cortex and causing reductions in cognitive resources,” he
says.
In a 2012 study,
he and his colleagues showed that hikers on a four-day backpacking trip
could solve significantly more puzzles requiring creativity when
compared to a control group of people waiting to take the same hike—in
fact, 47 percent more. Although other factors may account for his
results—for example, the exercise or the camaraderie of being out
together—prior studies have suggested that nature itself may play an
important role. One in Psychological Science
found that the impact of nature on attention restoration is what
accounted for improved scores on cognitive tests for the study
participants.
This phenomenon may be due to differences in brain activation when viewing natural scenes versus more built-up scenes—even for those who normally live in an urban environment. In a recent study
conducted by Peter Aspinall at Heriot-Watt University, Edinburgh, and
colleagues, participants who had their brains monitored continuously
using mobile electroencephalogram (EEG) while they walked through an
urban green space had brain EEG readings indicating lower frustration,
engagement, and arousal, and higher meditation levels while in the green
area, and higher engagement levels when moving out of the green area.
This lower engagement and arousal may be what allows for attention
restoration, encouraging a more open, meditative mindset.
It’s this kind of brain activity—sometimes referred to as “the brain default network”—that is tied to creative thinking,
says Strayer. He is currently repeating his earlier 2012 study with a
new group of hikers and recording their EEG activity and salivary
cortisol levels, before, during, and after a three-day hike. Early
analyses of EEG readings support the theory that hiking in nature seems
to rest people’s attention networks and to engage their default
networks.
Strayer and colleagues are also specifically looking at the affects
of technology by monitoring people’s EEG readings while they walk in an
arboretum, either while talking on their cell phone or not. So far,
they’ve found that participants with cell phones appear to have EEG
readings consistent with attention overload, and can recall only half as
many details of the arboretum they just passed through, compared to
those who were not on a cell phone.
Though Strayer’s findings are preliminary, they are consistent with
other people’s findings on the importance of nature to attention
restoration and creativity.
“If you’ve been using your brain to multitask—as most of us do most
of the day—and then you set that aside and go on a walk, without all of
the gadgets, you’ve let the prefrontal cortex recover,” says Strayer.
“And, that’s when we see these bursts in creativity, problem-solving,
and feelings of well-being.”
4. Nature may help you to be kind and generous
Whenever I go to places like Yosemite or the Big Sur Coast of
California, I seem to return to my home life ready to be more kind and
generous to those around me— just ask my husband and kids! Now some new
studies may shed light on why that is.
In a series of experiments
published in 2014, Juyoung Lee, GGSC director Dacher Keltner, and other
researchers at the University of California, Berkeley, studied the
potential impact of nature on willingness to be generous, trusting, and
helpful toward others, while considering what factors might influence
that relationship.
As part of their study, the researchers exposed participants to more
or less subjectively beautiful nature scenes (whose beauty levels were
rated independently) and then observed how participants behaved playing
two economics games—the Dictator Game and the Trust Game—that measure
generosity and trust, respectively. After being exposed to the more
beautiful nature scenes, participants acted more generously and more
trusting in the games than those who saw less beautiful scenes, and the
effects appeared to be due to corresponding increases in positive
emotion.
In another part of the study, the researchers asked people to fill
out a survey about their emotions while sitting at a table where more or
less beautiful plants were placed. Afterwards, the participants were
told that the experiment was over and they could leave, but that if they
wanted to they could volunteer to make paper cranes for a relief effort
program in Japan. The number of cranes they made (or didn’t make) was
used as a measure of “prosociality.,” or willingness to help.
Results showed that the presence of more beautiful plants
significantly increased the number of cranes made by participants, and
that this increase was, again, mediated by positive emotion elicited by
natural beauty. The researchers concluded that experiencing the beauty
of nature increases positive emotion—perhaps by inspiring awe, a feeling
akin to wonder, with the sense of being part of something bigger than
oneself—which then leads to prosocial behaviors.
Support for this theory comes from an experiment
conducted by Paul Piff of the University of California, Irvine, and
colleagues, in which participants staring up a grove of very tall trees
for as little as one minute experienced measurable increases in awe, and
demonstrated more helpful behavior and approached moral dilemmas with
ethically, than participants who spent the same amount of time looking
up at a high building.
5. Nature makes you “feel more alive”
With all of these benefits to being out in nature, it’s probably no surprise that something about nature makes us feel more alive and vital.
Being outdoors gives us energy, makes us happier, helps us to relieve
the everyday stresses of our overscheduled lives, opens the door to
creativity, and helps us to be kind to others.
No one knows if there is an ideal amount of nature exposure, though
Strayer says that longtime backpackers suggest a minimum of three days
to really unplug from our every day lives. Nor can anyone say for sure
how nature compares to other forms of stress relief or attention
restoration, such as sleep or meditation. Both Strayer and Bratman say
we need a lot more careful research to tease out these effects before we
come to any definitive conclusions.
Still, the research does suggest there’s something about nature that
keeps us psychologically healthy, and that’s good to know…especially
since nature is a resource that’s free and that many of us can access by
just walking outside our door.
Results like these should encourage us as a society to consider more carefully how we preserve our wilderness spaces and our urban parks.
And while the research may not be conclusive, Strayer is optimistic
that science will eventually catch up to what people like me have
intuited all along—that there’s something about nature that renews us,
allowing us feel better, to think better, and to deepen our
understanding of ourselves others.
“You can’t have centuries of people writing about this and not have
something going on,” says Strayer. “If you are constantly on a device or
in front of a screen, you’re missing out on something that’s pretty
spectacular: the real world.”
