The coming of spring

May 2, 2021

The Trees

by Philip Larkin

The trees are coming into leaf

like something almost being said;

the recent buds relax and spread,

their greenness is a kind of grief.

Is it that they are born again

and we grow old? No, they die too.

Their yearly trick of looking new

is written down in rings of grain.

Yet still the un-resting castles thresh

in full-grown thickness every May.

Last year is dead, they seem to say,

Begin afresh, afresh, afresh.

Here are some articles I think are interesting.  Maybe you will, too.

Steve Donziger Ecuador Case: Q&A With Human Rights Lawyer Under House Arrest by Jack Holmes for Esquire.  This lawyer won a lawsuit against Texaco (since acquired by Chevron), which lasted from 1993 to 2011, on behalf of farmers and indigenous people who lived in the Amazon rain forest, who accused the company of dumping cancer-causing toxic waste where they lived.  THey won a $9.8 billion award.  Chevron refused to pay and counter-sued their lawyer. Awaiting a verdict, he has been under house arrest for more than 580 days for refusing to hand over his computer and phone with confidential lawyer-client information on them.  Incredible!

How the West Lost COVID by David Wallace-West for New York magazine.  “How did so many rich countries get it so wrong?  How did others get it so right?”  This is the best article I’ve read on this particular topic.

Your Face Is Not Your Own by Kashmir Hill for the New York Times. “When a secretive start-up scraped the Internet to build a facial-recognition tool, it tested a legal and ethical limit—and blew the future of privacy in America wide open.”  (Hat tip to O.)

Nina Turner: “Good ideas are not enough.  We need to marry our ideas to power”, an interview for Jacobin magazine.  (Hat tip to Bill Harvey)

New study shows microplastics turn into ‘hubs’ for pathogens, antibiotic-resistant bacteria by Jesse Jenkins of New Jersey Institute of Technology.

The Crow Whisperer by Lauren Markham for Harper’s magazine.  “What happens when we talk to animals?”

The comeback of the bald eagle

November 27, 2020

Writers for Bored Panda say this map represents nesting places of bald eagles in Wisconsin in 1974 and 2019.  They attribute the 45-year comeback to the Clean Water Act.

Is green technology a mirage?

June 9, 2020

If a problem cannot be solved, it may not be a problem, but a fact.  [Attributed to Donald Rumsfeld]

It is possible to ignore reality, but it is not possible to ignore the consequences of ignoring reality.  [Attributed to Ayn Rand]

A new Michael Moore movie, “Planet of the Humans,” is an attack on the renewable energy movement.  Environmentalists by and large are outraged, and some demanded the movie be suppressed.

It actually was taken down from YouTube for 11 days, but it’s back up now.  If it is taken down again, you can view it on the Planet of the Humans Home page.

It runs for 100 minutes, which is a long time to watch something on a computer screen.  But it held my interest, and maybe it would hold yours, too.

In the first part of the movie, director Jeff Gibbs shows that solar panels and windmills are built through energy-intensive industrial processes and that they are made of materials such as high-grade quartz and rare earths that are scarce and non-renewable.

Solar panels and windmills wear out and have to be replaced.  In one scene, he visits Daggett, California, which pioneered in the development of solar and wind energy.  He sees a wasteland of dilapidated panels and windmills, because the pioneers couldn’t afford to keep them up.

And they don’t even fully replace fossil fuels.  Because of variability of sun and wind, backup electrical generators have to keep spinning, and the ones that aren’t hydroelectric use coal, gas and nuclear fuel.

In the second part, he looks at the environmental destruction caused by biomass energy.  There is no gain from freeing yourself from dependence on coal companies and embracing logging companies.

He makes a big point of pointing out the corporate ties of environmental organizations such as the Sierra Club and of environmentalists such as Al Gore, Robert F. Kennedy Jr., Richard Branson and even Bill McKibben.

He questions the whole premise, promoted by advocates such as Al Gore, that it is possible for middle-class Americans to enjoy our current material standard of living simply by adopting a new technology.

Fossil fuels made possible a world with an exponentially increasing population with the average individual using an ever-increasing amount of fuel and raw materials, Gibbs said.  Such a world isn’t sustainable, he said.

Coyote and badger hunt as a team

February 8, 2020

Coyotes and badgers sometimes hunt together as a team.

When the coyote chases a ground squirrel, the squirrel will take refuge in a burrow.  When the badger digs a ground squirrel out of a burrow, the squirrel will emerge from a different hole and run away.

Teaming up, the coyote and badger catch more prey than they could hunting apart.

The Hopi and Navajo have stories about the tricky coyote and stolid badger working together.  I myself never knew about this until I saw these videos on kottke.org.

Kangaroos hopping through the Australian snow

August 25, 2019

This video was shot about two weeks ago in New South Wales, Australia, where it is, of course, winter.

I understand that it’s a mistake to attribute human emotions to animals, but these guys sure look like they’re having a good time.

Peregrine falcons are feathered fighter jets

Peregrine falcons have a top speed of more than 200 miles per hour.

Photographer Christian Spencer shot these pictures of jacobin hummingbirds from his verandah in Rio de Janeiro.  The translucent wings act as a kind of prism that turns each bird into a tiny rainbow.

A giant floating ice disk forms in Maine

January 19, 2019

This video, taken last weekend, shows a massive spinning ice disk in the Presumptscot River near Westbrook, Maine, which is just west of Portland.  Local residents say it is 100 yards across, which would make it possibly the largest such ice disk on record.  Wonders never cease.

From the Big Bang to the origin of humanity

December 22, 2018

This 10-minute history of the universe shows all the amazing things that had to happen in order for the human race—that is, for you and me—to exist.

It’s quite a story.  My question is: Where are we in the story?  Are we near the end?  Or at the beginning?  Or somewhere in the middle?

I grew up reading science fiction, and envisioned the human race spreading out to the planets, then to other solar systems and perhaps other galaxies.  I now realize this can’t be taken for granted, but I also know I don’t have the knowledge to set limits on the future.  If life is a rare event in the universe, could it be the destiny of humanity to spread life beyond its point of origin?

Or are we at the end of the story?  Is it the destiny of the human race to use its intelligence to wipe itself out—through nuclear war, through plague, through runaway global warming or just through loss of the will to live.

Or is the history of civilization is just a blip in the life of a species evolved to be hunter-gatherers?

The total weight of life on earth

August 18, 2018

A group of scientists have written a paper for the U.S. National Academy of Sciences estimating the weight of the different kinds of life on earth.

The total carbon in all living things amounts to 550 billion metric tons, they wrote.  A metric ton is 2,200 pounds.

The weight of all the world’s plants is an estimated 450 billion metric tons.

The world’s bacteria weigh 70 billion metric tons.

All the world’s animals weigh only 2 billion metric tons, of which 1 billion tons consists of arthropods (including insects).

All the world’s humans total a mere 60 million metric tons.

Put another way, life on earth is, by weight, 82 percent plants, 13 percent bacteria and 5 percent everything else, of which 0.01 percent is human life.

A brave little kidney bean becomes a plant

August 4, 2018

I found this video on the kottke.org blog.  It is a time-lapse photo of a kidney bean sprouting into a plant, shot at the rate of one shot every 9 minutes 36 seconds and played at the rate of 30 frames per second.

The little bean seems strangely gallant to me.  It makes me feel proud to be a carbon-based life form.

Hellgrammites

Hellgrammites were much prized as bait when I was growing up in western Maryland along the Potomac River, but I never knew exactly what they were.   Now I do.

Fall foliage in New York’s Central Park

September 23, 2017

These time-lapse photos were taken by Jamie Scott. over a period of six months in Central Park in New York City.  He visited 15 locations, two days a week, just after sunrise, from August, 2011, through January, 2012.   The music is by Lower Dens.  I found this video on the Colossal website.
