(CNN) -- Well, we now have a new Republican Speaker of the House and a new year. But how much has really changed?
My dog Kenzie, a 50-pound black wolf -- more-or-less -- goes loping along the shore as is her custom, energetically invested in the obvious truth that all adventure lies at the tip of one's nose. If you can detect the scent and follow it, it will take you far. And soon, as always, she's way ahead.
This daily morning walk is how I take the pulse of the place, and my own. The rhythm of the year here on eastern Long Island beats to the pulse of a perpetual series of migrations, rivers of life along the leading line of coast. Fishes and birds mainly. But also migrating butterflies, dragonflies, whales, sea turtles, even tree frogs and toads and salamanders, whose migrations move them merely from woodland to wetland and back. Each kind has its own schedule, moves to its own drum.
Getting tuned-in to the migrants' urgent energies turns "four seasons" into a much more complex idea of what life does, what life is, of where life begins and goes.
To simplify, life -- Earth's trademark enterprise -- begins with plants, supported by air, water and soil, powered by sunlight. Basically, life on Earth is a story of plants making and animals taking.
We are all grass, pretty much. Now, humans take roughly 40% of the life that the land and the coastal seas produce. For one mid-sized creature, that is a staggering proportion.
The United Nations expects the population to grow by mid-century to more than 9 billion people; that's two more Chinas. The world adds about 70 million people each year, twice as many as live in California.
Meanwhile, populations of fishes, amphibians, mammals, reptiles and birds have declined about 30% worldwide since 1970, according to the World Wildlife Fund. The last extinction wave this severe snuffed the dinosaurs.
We're pumping freshwater faster than rain falls, catching fish faster than they spawn. Forty percent of tropical coral reefs are rapidly deteriorating; none of the rest are considered safe. Forests are shrinking by about an acre per second.
Compared with the day 13 colonies on the sunrise side of a wilderness continent asserted independence as the United States, the planet's atmosphere is quite different. Ozone: thinner. Carbon dioxide: denser by a third and concentrating further.
Synthetic fertilizers have doubled the global nitrogen flow to living systems, washing down rivers and, since the 1970s, creating hundreds of oxygen-starved seafloor "dead zones."
Americans -- only 5% of the world population -- use roughly 30% of the world's nonrenewable energy and minerals, according to Worldwatch Institute. The Convention on Biodiversity aims -- aimed -- to protect the diversity of living things, but its own assessment says, "Biodiversity is in decline at all levels and geographical scales," a situation "likely to continue for the foreseeable future."
In accounting terms, we're running a deficit, eating into our principal, running down and liquidating our natural capital assets. The question: Why are we letting this happen?
For the longest time, people didn't even have a real sense of, well, time. Until the early 1800s, Western people had essentially no concept of Earth's age, or that certain formerly living things had become extinct. When Charles Darwin departed for his voyage on the Beagle, the word "scientist" did not exist.
Since the mid-1800s, we've finally started learning basic things about how the world actually works. We understand the water cycle, carbon cycle, nitrogen cycle, the composition of air and the circulation of oceans. We created the entirely new fields of geology, biology, ecology, genetics and hi-tech medicine.
But civilization's way of doing business remains rooted in philosophies, religious traditions and ethical frameworks written many centuries ago. The first stock exchange opened in 1602, in Amsterdam. By 1637, "tulip mania" had caused the first speculation bubble and crash.
Not a lot has changed. Virtually every business still uses the double-entry bookkeeping and accounting used in 13th-century Venice, first written down in the 1400s by Leonardo da Vinci's friend, the Franciscan monk Luca Pacioli. His book Summa de Arithmetica established the concept that banks' main assets are other people's debts -- and we know where that's gotten us recently.
So, our daily dealings are still heavily influenced by ideas that were pretty much set before anyone knew the world was round, before it ever occurred to anyone that the world changes, and certainly before anyone suspected that anything people do could change the world.
In many ways, the ways we operate reflect how we understood the world when we didn't understand the world at all. You wouldn't treat an illness by calling a medical doctor from the Middle Ages, but we run the modern world with only pre-modern comprehension. If markets understood the world, things that harmed the world would be prohibitively expensive.
Our institutions are so out of sync with the way the world really works that they're essentially irrational. And it shows. That's why we so blithely allow ourselves to shrink forests, empty oceans, alter the atmosphere, endanger our children's times and risk so much of the world.
Despite overhauled ways of knowing, old thinking prevails. And if the whole human enterprise has one fatal shortcoming, this is likely it.
But I'll make a casual wager: Things now largely ignored will become too obvious to deny. It becomes a question of "When?"
Here's what I think is obvious: Civilization can't keep running on nonrenewable fossil fuels because by definition they will run out. Eventually we will either have to scale up renewable energy or civilization will end. And we can't keep adding people infinitely to a finite planet. That only shortens the time we have for the energy transition. If we begin accepting the obvious, and start making the transition now, I think we might be OK.
Republicans now have more seats in Congress, but, really, is saving civilization a partisan issue? Is investing in America's infrastructure and creating the jobs to build and scale up new energy technologies a partisan issue? We need to begin seeing that the real issues are much bigger than party loyalties.
