social interaction in cities

Here’s an interesting article from the University of Bern, Switzerland, on social interaction in cities. The engineer in me likes to see some hard data and theory applied in the social sciences.

Cities and the Structure of Social Interactions: Evidence from Mobile Phone Data

Social interactions are considered pivotal to urban agglomeration forces. This study employs a unique dataset on mobile phone calls to examine how social interactions differ across cities and peripheral areas. We first show that geographical distance is highly detrimental to interpersonal exchange. We then reveal that individuals residing in high-density locations do not benefit from larger social networks, but from a more efficient structure in terms of higher matching quality and lower clustering. These results are derived from two complementary approaches: Based on a link formation model, we examine how geographical distance, network overlap, and sociodemographic (dis)similarities impact the likelihood that two agents interact. We further decompose the effects from individual, location, and time specific determinants on micro-level network measures by exploiting information on mobile phone users who change their place of residence.

And here’s a more touchy-feely article in Vox on how the U.S. suburban development pattern discourages social interaction.

the key ingredient for the formation of friendships is repeated spontaneous contact. That’s why we make friends in school — because we are forced into regular contact with the same people. It is the natural soil out of which friendship grows…

This kind of spontaneous social mixing doesn’t disappear in post-collegiate life. We bond with co-workers, especially in those scrappy early jobs, and the people who share our rented homes and apartments.

But when we marry and start a family, we are pushed, by custom, policy, and expectation, to move into our own houses. And when we have kids, we find ourselves tied to those houses. Many if not most neighborhoods these days are not safe for unsupervised kid frolicking. In lower-income areas there are no sidewalks; in higher-income areas there are wide streets abutted by large garages. In both cases, the neighborhoods are made for cars, not kids. So kids stay inside playing Xbox, and families don’t leave except to drive somewhere.

I buy this about 75%. I am lucky to live and work in a highly walkable urban neighborhood, and I do have a lot of friendly spontaneous interactions with people around the neighborhood. I have a “scrappy” job where I bond with my co-workers, like soldiers in the trenches. I am also a middle-aged family person and somewhat of an introvert. Part of the reason I don’t have a lot of close adult friendships outside of work and family is that between work and family, I have all the human interaction I can really handle. If I have 15 minutes free on a given day, I would rather spend it alone than interacting with yet another person. I suppose this could change when the kids get a little older and/or when I don’t have to work so much, assuming I live long enough for these things to happen. So I’m just saying there are family pressures, financial and career pressures, and personality differences that influence these things alongside urban form.

Back to the first article, it suggests that high school, college, band camp, and even most workplaces might not be the best model of the most fulfilling and productive social interactions that can develop among adults in the best cities. In high school and college we tend to form small, tight-knit groups where most people in the group network only within the group. The first article above, if I am interpreting it correctly, describes a case where not only are individuals interacting frequently within a social network, but relatively open social networks themselves are interacting with each other as individuals within them interact in random and freewheeling ways. It’s wonderful. Now if you’ll excuse me I’m going to sit on my couch for a little while, watch some TV, unwind and recharge so I can handle the social interaction that will be thrown at me tomorrow.

September 2016 in Review

3 most frightening stories

  • The U.S. and Russia may have blundered into a proxy war in Syria. And on a loosely related war-and-peace note, Curtis LeMay was a crazy bastard.
  • The ecological footprint situation is not looking too promising: “from 1993 to 2009…while the human population has increased by 23% and the world economy has grown 153%, the human footprint has increased by just 9%. Still, 75% the planet’s land surface is experiencing measurable human pressures. Moreover, pressures are perversely intense, widespread and rapidly intensifying in places with high biodiversity.” Meanwhile, as of 2002 “we appropriate over 40% of the net primary productivity (the green material) produced on Earth each year (Vitousek et al. 1986, Rojstaczer et al. 2001). We consume 35% of the productivity of the oceanic shelf (Pauly and Christensen 1995), and we use 60% of freshwater run-off (Postel et al. 1996). The unprecedented escalation in both human population and consumption in the 20th century has resulted in environmental crises never before encountered in the history of humankind and the world (McNeill 2000). E. O. Wilson (2002) claims it would now take four Earths to meet the consumption demands of the current human population, if every human consumed at the level of the average US inhabitant.” And finally, 30% of African elephants have been lost in the last 7 years.
  • Car accidents are the leading cause of death for children ages 5 to 24. The obsession with car seats may not be saving all that many lives, while keeping children out of cars as much as possible would be 100% guaranteed to save lives. And one thing that would be guaranteed to help us create more walkable neighborhoods and therefore save children’s lives: getting rid of minimum parking requirements in cities once and for all. And yet you don’t hear this debate being framed in moral terms.

3 most hopeful stories

3 most interesting stories

  • Monsanto is trying to help honeybees (which seems good) by monkeying with RNA (which seems a little frightening). Yes, biotech is coming.
  • Some people think teaching algebra to children may actually be bad. Writing still seems to be good.
  • There have been a number of attempts to identify and classify the basic types of literary plots.

minimum parking requirements

Here’s a short, visually engaging video about the problem with minimum parking requirements. Apparently, this worked in Ottawa. I don’t want to be cynical, but I am not convinced the residents, politicians, and bureaucrats of my town would respond similarly to such a logical argument. I would love for everyone to prove me wrong.

autonomous vehicles and suburban sprawl

Planetizen says autonomous vehicles won’t lead to more sprawl.

While we recognize the synergies AVs have with transit (something that is likely to be impacted by the technologythat we will discuss in the future), we do not share the belief that AVs will cause a new, unprecedented wave of sprawl. Rather, growing patterns of sprawl and longer “super-commutes” are unlikely outcomes of AVs for three key reasons: 1) the presence of existing land use, transportation, and infrastructure controls and growth management plans; 2) trends in housing consumption and residential preferences; and 3) social dynamics and the emergence of more informed decision-making.

I think the biggest effect of autonomous vehicles within urban areas will be on parking. At the moment, we have enormous numbers of parked vehicles taking up enormous amounts of space right where we are trying to live, work, and shop. With autonomous vehicles, we should either be able to share them, meaning a smaller number of vehicles in motion more of the time rather than parked, or if we really still want to own them, they can go park themselves in out-of-the-way places and come get us when we call them. This could lead to some very vibrant, social, creative, green urban areas.

I can also imagine some people will choose to live completely cloistered lives where they are sitting in comfortable vehicles several hours a day while going to and from work, or going to far-away vacation homes on the weekend. You could even imagine people choosing to live full-time in autonomous RVs.

public buses vs. Uber Pool

This article talks about the idea of shifting from public bus systems to Uber Pool, and comes out against it.

Uber Pool’s cost disadvantage over public transit might disappear if a new pilot program in Boston catches on. This month, Uber announced that it would introduce monthly Uber Pool passes—like transit passes—for just $2 per ride, or less than the MBTA’s $2.25 fare. While these temporary low fares are no doubt a money-losing loss leader, if UberPool fares are anywhere close to the price of public transit it would seem like we’re probably looking at a massive shift from public transit to these sorts of ride-hailing services. And wouldn’t that be a good thing, if it’s both faster and nearly as cheap?

But here’s where the importance space-efficiency comes in. When one person switches from the bus to Uber, two things happen. One is that they get a faster trip almost by definition: A vehicle that makes many stops (the bus) is going to be slower than a vehicle that makes few or no stops (the Uber) unless the bus has some other advantage, like transit lanes that allow it to avoid traffic congestion. And the vast majority of American bus lines are given no such benefit.

The second thing is that they switch from a very space-efficient vehicle, where they probably take up only a few square feet on the road, to a very space-inefficient vehicle, where they take up many, many times more.

It seems to me there is a middle ground here. A technology like Uber Pool, whether in private or public hands, could put the right size vehicles on the right routes at the right times. On some routes at some times, that might be a golf cart, and at others it might be a double decker bus. A system like this could be very flexible and adaptable.  Of course, using our own muscle power for as many trips as possible is also an important part of the equation and if we really want to be sustainable we need to design our towns and lives so that is the best choice for the majority of our daily trips. Communication technology and even virtual reality are another part of the equation because they could allow us to have the personal interaction we need in our work and social lives without physical distance being a factor.

green space and mental health

Here’s a new study on green space and health, based on the large-scale nurses’s study. One interesting finding is that mental health explains around 30% of the total benefit.

Exposure to Greenness and Mortality in a Nationwide Prospective Cohort Study of Women

In models adjusted for mortality risk factors (age, race/ethnicity, smoking, and individual- and area-level socioeconomic status), women living in the highest quintile of cumulative average greenness (accounting for changes in residence during follow-up) in the 250m area around their home had a 12% lower rate of all-cause non-accidental mortality (95% CI 0.82, 0.94) compared to those in the lowest quintile. Results were consistent for the 1,250m area, although the relationship was slightly attenuated. These associations were strongest for respiratory and cancer mortality. Findings from a mediation analysis suggest that the association between greenness and mortality may be at least partly mediated by physical activity, particulate matter less than 2.5 micrometers, social engagement, and depression.

fire trucks

I want to start this post by thanking the fire department for what they do. Obviously, they save lives and property, and have one of the least morally ambiguous jobs out there. That said, they are so almost universally revered that you wonder if it is okay to voice any doubts about the way they do things. So I was surprised to see this article voicing some of my own questions about whether fire trucks need to be so big. When I lived in Singapore, I noticed that they didn’t use the huge fire trucks – they were more like vans, and used some kind of foam rather than pure water. Now, the buildings in Singapore are almost all very modern, and all have prominent water hookups, and streets are very wide. Singapore chose to bulldoze a lot of its older buildings and streets at some point and start fresh, and I would not necessarily want my home city of Philadelphia to do that – I love our narrow streets, largely 19th century housing including my own house, and the walkability, mom-and-pop businesses and odd scattered public spaces it leads to. Another thing is that as an engineer occasionally involved in aspects of street design, the fire department is sometimes a voice in opposition to change. Take bumpouts for example that create  a shorter crossing distance for school children at intersections. These will save lives. The fire department will say that these slow down fire trucks making turns, and anything that slows down fire trucks could cost lives. I am not saying this is the wrong dialog to have, but the fire department shouldn’t always be the bullies getting their way, the two safety issues should be weighed against each other and a rational (okay, at least political) decision made.

January 2016 in Review

I’m going to try picking the three most frightening posts, three most hopeful posts, and three most interesting posts (that are not particularly frightening or hopeful) from January.

3 most frightening posts

  • Paul Ehrlich is still worried about population. 82% of scientists agree.
  • Thomas Picketty (paraphrased by J. Bradford Delong) says inequality and slow growth are the norm for a capitalist society. Joseph Stiglitz has some politically difficult solutions: “Far-reaching redistribution of income would help, as would deep reform of our financial system – not just to prevent it from imposing harm on the rest of us, but also to get banks and other financial institutions to do what they are supposed to do: match long-term savings to long-term investment needs.”
  • Meanwhile, government for and by big business means the “Deep State” is really in control of the U.S. In our big cities, the enormous and enormously dysfunctional police-court-prison system holds sway over the poor.

3 most hopeful posts

3 most interesting posts

  • There are some arguments in favor of genetically modified food – they have increased yields of some grains, and there is promise they could increase fish yields. 88% of scientists responding to a Pew survey said they think genetically modified food is safe, but only 37% of the U.S. public thinks so. In other biotech news, Obama’s State of the Union announced a new initiative to try to cure cancer. In other food news, red meat is out.
  • Not only is cash becoming obsolete, any physical form of payment at all may become obsolete.
  • The World Economic Forum focused on technology: “The possibilities of billions of people connected by mobile devices, with unprecedented processing power, storage capacity, and access to knowledge, are unlimited. And these possibilities will be multiplied by emerging technology breakthroughs in fields such as artificial intelligence, robotics, the Internet of Things, autonomous vehicles, 3-D printing, nanotechnology, biotechnology, materials science, energy storage, and quantum computing.”

 

2015 Year in Review

I’m going to try picking the most frightening, most hopeful, and most interesting post from each month. If the most interesting is also the most frightening or most hopeful, I’ll pick the next most interesting. Then I’ll have 12 nominees in each category and I’ll try to pick the most frightening, hopeful, and interesting posts of the year.

JANUARY

Most frightening: Johan Rockstrom and company have updated their 2009 planetary boundaries work. The news is not getting any better. 4 of the 9 boundaries are not in the “safe operating space”: climate change, loss of biosphere integrity, land-system change, altered biogeochemical cycles (phosphorus and nitrogen).

Most hopeful: It is starting to seem politically possible for the U.S. to strengthen regulation of risk-taking by huge financial firms.

Most interesting: Taxi medallions have been called the “best investment in America”, but now ride-sharing services may destroy them.

FEBRUARY

Most frightening: There are some depressing new books out there about all the bad things that could happen to the world, from nuclear terrorism to pandemics. Also a “financial black hole”, a “major breakdown of the Internet”, “the underpopulation bomb”, the “death of death”, and more!

Most hopeful: A new study suggests a sudden, catastrophic climate tipping point may not be too likely.

Most interesting: Government fragmentation explains at least part of suburban sprawl and urban decline in U.S. states, with Pennsylvania among the worst.

MARCH

Most frightening: The drought in California and the U.S. Southwest is the worst ever, including one that wiped out an earlier civilization in the same spot. At least it is being taken seriously and some policies are being put in place. Meanwhile Sao Paulo, Brazil is emerging as a cautionary tale of what happens when the political and professional leadership in a major urban area fail to take drought seriously. Some people are predicting that water shortages could spark serious social unrest in developing countries.

Most hopeful: If we want to design ecosystems or just do some wildlife-friendly gardening, there is plenty of information on plants, butterflies, and pollinators out there. There is also an emerging literature on spatial habitat fragmentation and how it can be purposely designed and controlled for maximum benefit.

Most interesting (I just couldn’t choose between these):

  • Innovation in synthetic drugs is quickly outpacing the ability of regulatory agencies to adapt. (I struggled whether to put this in the negative or positive column. Drugs certainly cause suffering and social problems. But that is true of legal tobacco and alcohol, and prescription drugs, as well as illegal drugs. The policy frameworks countries have used to deal with illegal drugs in the past half century or so, most conspicuously the U.S. “war” on drugs, have led to more harm than good, and it is a good thing that governments are starting to acknowledge this and consider new policies for the changing times.)
  • Germ-line engineering is much further along than anyone imagined.” This means basically editing the DNA of egg and sperm cells at will. I put this in the positive column because it can mean huge health advances. Obviously there are risks and ethical concerns too.

APRIL

Most frightening: A group of well-known economists is concerned that the entire world has entered a period of persistently low economic growth, or “secular stagnation“.

Most hopeful: Donald Shoup, author of The High Cost of Free Parking, is retiring. That might sound bad, but his ground-breaking ideas are continuing on and actually seem to be going mainstream.

Most interesting:

  • Biotechnology may soon bring us the tools to seriously monkey with photosynthesis. (This is one of those stories where I struggle between the positive and negative columns, but clearly there is a potential upside when we will have so many mouths to feed.)
  • Peter Thiel thinks we can live forever. (positive, but do see my earlier comment about mouths to feed…)

MAY

Most frightening: We’ve hit 400 ppm carbon dioxide in the atmosphere, not just some places sometimes but pretty much everywhere, all the time.

Most hopeful: The rhetoric on renewable energy is really changing as it starts to seriously challenge fossil fuels on economic grounds. Following the Fukushima disaster, when all Japan’s nuclear reactors were shut down, the gap was made up largely with liquid natural gas and with almost no disruption of consumer service. But renewables also grew explosively. Some are suggesting Saudi Arabia is supporting lower oil prices in part to stay competitive with renewables. Wind and solar capacity are growing quickly in many parts of the world.Lester Brown says the tide has turned and renewables are now unstoppable.

Most interesting: Human chemical use to combat diseases, bugs, and weeds is causing the diseases, bugs and weeds to evolve fast.

JUNE

Most frightening: One estimate says that climate change may reduce global economic growth by 3% in 2050 and 7-8% by 2100. Climate change may also double the frequency of El Nino. The DICE model is available to look at climate-economy linkages. Dennis Meadows and Jorgen Randers describe what a coming long, slow decline might look like. Rising temperatures in the Arctic are drying things out, leading to more fires, which burns more carbon, which raises temperatures, in an accelerating feedback loop.

Most hopeful: Stock values of U.S. coal companies have collapsed.

Most interesting: According to Paul Romer, academic economics has lost its way and is bogged down in “mathiness”.

JULY

Most frightening: James Hansen is warning of much faster and greater sea level rise than current mainstream expectations.

Most hopeful: Edible Forest Gardens is a great two book set that lays out an agenda for productive and low-input ecological garden design in eastern North America. You can turn your lawn into a food forest today.

Most interesting:

AUGUST

Most frightening: Steven Hawking is worried about an artificial intelligence arms race starting “within years, not decades”.

Most hopeful: It may be possible to capture atmospheric carbon and turn it into high-strength, valuable carbon fiber. This sounds like a potential game-changer to me, because if carbon fiber were cheap it could be substituted for a lot of heavy, toxic and energy-intensive materials we use now, and open up possibilities for entirely new types of structures and vehicles.

Most interesting:

  • gene drive” technology helps make sure that genetically engineered traits are passed along to offspring.
  • Technology marches on – quantum computing is in early emergence, the “internet of things” is arriving at the “peak of inflated expectations”, big data is crashing into the “trough of disillusionment”, virtual reality is beginning its assent to the “plateau of productivity”, and speech recognition is arriving on the plateau. And super-intelligent rodents may be on the way.
  • Robotics may be on the verge of a Cambrian explosion, which will almost certainly be bad for some types of jobs, but will also bring us things like cars that avoid pedestrians and computer chips powered by sweat. I for one am excited to be alive at this moment in history.

SEPTEMBER

Most frightening: Climate may be playing a role in the current refugee crisis, and the future may hold much more of this.

Most hopeful: The right mix of variety and repetition might be the key to learning.

Most interesting: Edward Tufte does not like Infographics.

OCTOBER

Most frightening: Corrupt Russian officials appear to be selling nuclear materials in Moldova.

Most hopeful: Elephants seem to have very low rates of cancer. Maybe we could learn their secrets.

Most interesting: Stephen Hawking is worried about inequality and technological unemployment.

NOVEMBER

Most frightening: I noticed that Robert Costanza in 2014 issued an update to his seminal 1997 paper on ecosystem services. He now estimates their value at $125 trillion per year, compared to a world economy of $77 trillion per year. Each year we are using up about $4-20 trillion in value more than the Earth is able to replenish. The correct conclusion here is that we can’t live without ecosystem services any time soon with our current level of knowledge and wealth, and yet we are depleting the natural capital that produces them. We were all lucky enough to inherit an enormous trust fund of natural capital at birth, and we are spending it down like the spoiled trust fund babies we are. We are living it up, and we measure our wealth based on that lifestyle, but we don’t have a bank statement so we don’t actually know when that nest egg is going to run out.

Most hopeful: There are plenty of ways to store intermittent solar and wind power so they can provide a constant, reliable electricity source.

Most interesting: Asimov’s yeast vats are finally here. This is good because it allows us to produce food without photosynthesis, but bad because it allows us to produce food without photosynthesis.

DECEMBER

Most frightening: Cyberattacks or superflares could destroy the U.S. electric grid.

Most hopeful: We had the Paris agreement. It is possible to be cynical about this agreement but it is the best agreement we have had so far.

Most interesting: I mused about whether it is really possible the U.S. could go down a fascist path. I reviewed Robert Paxton’s five stages of fascism. I am a little worried, but some knowledgeable people say not to worry. After reading Alice Goffman’s book On the Runthough, one could conclude that a certain segment of our population is living in a fascist police state right now. There is some fairly strong evidence that financial crises have tended to favor the rise of the right wing in Europe.

DISCUSSION

Well, one thing that certainly jumps out on the technology front is biotechnology. We have a couple articles about the possibility of drastic increases in the human lifespan, and what that would mean. “Germ-line engineering”, “gene drive”, and “CRISPR” are all ways of monkeying with DNA directly, even in ways that get passed along to offspring. To produce more food, we may be able to monkey with the fundamentals of photosynthesis, and if that doesn’t work we can use genetically engineered yeast to bypass photosythesis entirely.

At the risk of copyright infringement, I am reproducing the “Gartner hype cycle” below, which was mentioned in one of the posts from August.

Gartner Hype Cycle

Gartner Hype Cycle

Government and corporate labs have been making huge advances in biotechnology in the last decade or so, so it is well beyond the “innovation trigger”. It has not yet reached the “peak of inflated expectations” where it would explode onto the commercial and media scene with a lot of fanfare. I expect that will happen. We will probably see a biotech boom, a biotech bubble, and a biotech bust similar to what we saw with the computers and the internet. And then it will quietly pervade every aspect of our daily lives similar to computers and the internet, and our children will shrug and assume it has always been that way.

Obviously there are dangers. A generation of people that refuse to die on time would be one. Bioterrorism is obviously one. Then there is the more subtle matter that as we raise the limit on the size our population and consumption level can attain, the footprint of our civilization will just grow to meet the new limit. When and how we come up against these limits, and what to do about it, is the subject of the updates to two seminal papers on these issues, by Rockstrom and Costanza. We have entered an “unsafe operating space” (Rockstrom), where we are depleting much more natural capital each year than the planet can replenish (Costanza), and there will be consequences. The Paris agreement is one hopeful sign that our civilization might be able to deal with these problems, but even if we deal with the carbon emission problem, it might be too late to prevent the worst consequences, and there are going to be “layers of limits” as the authors of Limits to Growth put it all those decades ago. If we take care of the global warming problem and figure out a way to grow food for 50 billion people, eventually we will grow to 50 billion people and have to think of something else.

So without further ado:

Most frightening: I can’t pick just one. In the relatively near term, it’s the stalling out of the world economy; the convergence of climate change, drought, and the challenge of feeding so many people; and the ongoing risks from nuclear and biological weapons.

Most hopeful: I see some hope on energy and land use issues. The Paris agreement, combined with renewable energy and energy storage breakthroughs, the potential for much more efficient use of space in cities rather than letting cars take up most of the space, are all hopeful. The possibility of making carbon fiber out of carbon emissions is a particularly intriguing one. At my personal scale, I am excited to do some sustainable gardening of native species that can feed both people and wildlife. I don’t expect my tiny garden to make a major difference in the world, but if we all had sustainable gardens, they were all connected, and we weren’t wasting so much space on roads and parking, it could start adding up to a much more sustainable land use pattern.

Most interesting: I’ve already mentioned a lot of stuff, so I will just pick something I haven’t already mentioned in the discussion above: the rise of synthetic drugs. It’s just an interesting article and makes you think about what it will mean to have advanced chemical, information, and biological technologies in the hands of the little guy, actually many, many little guys. It is a brave, new, dangerous, exciting world indeed. Happy new year!

December 2015 in Review

Now it’s time to review December 2015, before we get on to reviewing 2015 as a whole.

Negative stories (-10):

  • Some car dealers are deliberately talking customers out of buying electric cars that they want, because the car dealer will make less money on oil changes. (-1)
  • Breaking news: we can’t believe everything we hear on the internet. Some of it is deliberate government and corporate propaganda, and some is “online filter bubbles” or marketing algorithms telling each of us only what we want to hear. Data used by all these algorithms is becoming more and more valuable. (-1)
  • Cyberattacks or superflares could destroy the U.S. electric grid. (-1)
  • Guns cause gut-wrenching, accidental deaths of children quite frequently in the U.S. The U.S. has a rate of violent assault 5-10 times higher than our close Anglo-American cousins, which in turn have higher rates than most of Europe and developed Asia. (-1)
  • I mused about whether it is really possible the U.S. could go down a fascist path. I reviewed Robert Paxton’s five stages of fascism. I am a little worried, but some knowledgeable people say not to worry. After reading Alice Goffman’s book On the Run though, one could conclude that a certain segment of our population is living in a fascist police state right now. There is some fairly strong evidence that financial crises have tended to favor the rise of the right wing in Europe. (-2)
  • After more than a decade of drought, there may not be enough water to sustain both Lake Powell and Lake Mead in the U.S. desert southwest. Some are suggesting draining Lake Powell. (-1)
  • This year’s “super El Nino” might have happened with or without climate change, but climate change made it more likely. I have to admit though I enjoyed sitting on my front porch in shorts on Christmas here in Philadelphia. (-1)
  • Jeffrey Sachs makes a pretty good case that the rise of violent religious fanaticism in the Middle East is largely the CIA’s fault. (-2)

Positive stories (+13):

    • Las Vegas is planning to go all renewable by 2017, mostly centralized solar. (+1)
    • Children have a natural aptitude for learning to recognize patterns. Now all we have to do is figure out which patterns we should be teaching them to recognize. (+1)
    • Some U.S. Presidential candidates want to invest in infrastructure, which is good. A national infrastructure plan might also be good. (+1)
    • Ericcson released some technology predictions for 2016 and beyond: Artificial intelligence will start to assist us without the need for smartphone screens. Virtual reality will start to come into its own for tech support, sports, dating, and shopping. And we will start to see more sensors embedded in our homes and eventually our bodies. (+1)
    • Trends in Ecology and Evolution made some technology predictions too: “managed bees as transporters of biological control agents, artificial superintelligence, electric pulse trawling, testosterone in the aquatic environment, building artificial oceanic islands, and the incorporation of ecological civilization principles into government policies in China”. (+1)
    • A serious but treatable infection can destroy a tumor. (+1)
    • Self-driving cars could drastically reduce the amount of land required for parking in cities. There are some moves toward car-free central cities around the world. (+3)
    • We had the Paris agreement. It is possible to be cynical about this agreement but it is the best agreement we have had so far. (+2)
    • New York City recently finished planting a million trees. (+2)

So we end the year on a positive note!
