Social Justice and Climate Change

smokestacksAs I mentioned in my May 12, 2020 blog, the people who are hurt the most from pollution and the impacts from our changing climate are often people with the least means to avoid these problems. People who live downstream or downwind from an ‘out of compliance’ manufacturing site or power plant have the most exposure to air and water pollution, and they are without the financial resources to move to a more expensive but cleaner area. They may benefit from the power generated or commercial goods produced, but they often suffer most from the exposure to toxic chemicals. This is one good reason that we have regulations and why we need to enforce these regulations at all times. The costs of good environmental regulation has proven to be far less than the health and economic benefits that we all gain.

Caring for the environment may seem like a luxury to some because it takes time, money, knowledge, and political power to clean things up and keep them clean. The exposure to toxic chemicals has been made worse by the practice of redlining in many parts of the country. Redlining is the systematic denial of various services by government agencies and the private sector to residents of specific neighborhoods – most notably black and brown communities. This is done either directly or through the selective raising of prices. Just think how these historic and current practices make things worse for some sectors of our population. Here are a few ways that people who are trapped in poor areas suffer more than the rest of us when it comes to the wide-ranging impacts of a changing climate.

Health impacts in poor areas:

  1. Existing social, health, infrastructure, food supply, and housing vulnerabilities in poor areas will impact residents’ ability to respond in the face of a changing climate.
  2. Weather – Major rain storms threaten all of us but especially people living in low-lying areas with inadequate and poorly maintained stormwater, sewage, transportation, and electrical infrastructure.
  3. Air Quality – Coal, oil, and natural gas fired power plants and manufacturing facilities are often located in or near poor areas. They can emit toxins, e.g., coal plants often emit mercury, arsenic, lead, particulate matter, sulfur dioxide, and nitrogen dioxide.
  4. Higher temperatures are exacerbated by the ‘Heat Island Affect’, and our cities often lack the cooling and cleaning benefits of a forested area. This leads to higher temperatures and greater risk of heat stroke, COPD, heart attack, and premature death.
  5. Increased heat and ozone levels result in more asthma attacks and hospitalization.
  6. Extreme heat and extreme precipitation events increase the risk of salmonella infections.
  7. Mental Health – Greater impacts result from repeated exposures and climatic events.

For further information, I would recommend resources from EcoAmerica. They have an entire climate and health program. Climate Justice Alliance is also a good resource for climate and social justice concerns.




Explore Columbia on Foot – Fall Walks begin on Saturday 9/8/18. Meet at People Tree by Lakefront at 10am. We’ll explore downtown.

Here is the official schedule for the series of walks that I will lead around Columbia this Fall. Hope to see you on one of them. Note that two are on Saturdays and the rest are on Thursday mornings.


Nature Through a 4-year-old’s Eyes Explorer’s Club #4 – Woods  

ribbon snakeI love walking through the woods – they are always changing. When I go with my 4-year old sidekick, we ask each other a lot of questions and take the time to explore whatever we stumble across. We have learned that we have more fun when we stop and take the time to observe nature.


She likes to collect nuts – I identify them for her and I often end up holding them.

“Grandpa. Hold onto these nuts.”


“I want to save them.”

You can’t argue with that. In fact she has small hordes of nuts and rocks stored in the cubbyholes in our cars and around our house. She always checks them out and entertains herself a lot by going through her collections when driving in the car or staying overnight.

When my pockets are full on hikes, we try to find a hole in a tree and put them in the hole – helping the animals who live in the tree build up their food storage for the winter. We know better than to reach into these crevasses, knowing there might be a hungry squirrel, raccoon, or snake nesting in there.

Speaking of snakes. My little friend and I found a snake lying on a gravel road.

“Is it alive?”

“I don’t think so. It’s not moving. Let’s take a stick to see.”

“It must be dead.”

“Yeah. I see three puncture wounds near its head. I wonder if a hawk, a fox, a coyote, or a cat killed it or was it just run over by a car?”

It was beautiful creature. Long stripes lay along both sides. We had seen garter snakes and black snakes before but this was more colorful. We determined that is was not poisonous because its head was not triangular or coppery. It was a sleek Eastern ribbon snake.

black rat snake“Can I touch it?”

I thought about this for a moment and agree. So a certain 4-year old was authorized to pick it up. It was about 20 inches long. We took it home and put it in a ziploc bag and showed it off to all the people who came by over the next few days. After a week, the other residents of the house started complaining.

“What is that smell?”

We just looked at each other. “What smell.” We were instructed to bury our treasure.  We discussed how it would make the soil richer for new life to come.

As a grandparent I want her to be aware of and respectful of nature. I want her to love the outdoors and to always be curious. I also want her to learn to think logically and creatively when it comes to how she interacts with all of life on this planet.

Most snakes in this region are beneficial and not poisonous. For example, black rat snakes are quite common and play an important role in keeping the ecosystem in balance. They also get to be 6-feet long and so they can be a little scary. In all my hikes I have only seen a single poisonous copperhead. It just lay there, it was not aggressive at all. But I did make a wide circle around it.

Nature Through a 4-year-old’s Eyes Explorer’s Club #3 – Rivers    

Crayfish3It’s hard to keep kids out of rivers. There’s a natural attraction for Homo sapiens to throw stones, build dams, and to get wet. How can you experience a river without getting wet? I hope I never lose this impulse.

I can’t tell you how many times when walking along a river, I turn around and someone in my care has her feet in the water. This must be genetic. My mother always did this as well.

Recently, I and a certain 4-year old were negotiating rules and setting limits for her activity on a sandbar. Somehow, I found myself needing to get in the water as well in order to enforce the rules. This of course led to a lot of splashing and both of us getting drenched.

4-year olds, as you know, are great collectors of things. So when one is standing on a sand bar with thousands of pebbles, cobbles, and rocks, a few get picked up.

“What’s this grandpa?”

As a geologist I feel obliged to try to identify every rock that she brings to me. She now knows the name of some of them as well as I do. And of course, she wants to keep many of them so someone has to put them in his pocket.

But what I like even as much as the stones she finds are the other living critters in the water. Today she is the first to spy and marvel at the water-striders.

water-strider-e1534377996743.jpg“How do they do that?” she asks.

I of course have no idea – unless I resort to my phone, which is safely on the bank. All I know are that arthropods are good indicators of water quality.

“Come on, let’s catch one!” She chases after them trying in vain to grab one to look at. I know better and don’t move. They are much too fast.

I stand motionless and look for fish, wondering if there are any trout, bass, perch, suckers, catfish, or minnows that can be seen or caught. Then I check out signs for otters, muskrats, beavers along the banks. There are often numerous signs that beavers have visited many of the lakes and rivers in this area. I point out anything I find. She is mostly interested in the fast-flowing parts of the river. I keep a watchful eye on where she is at all times.

While she is collecting rocks, I wade along the banks, just watching for anything unusual. I see something, cobble-sized, dart right in front of me. I bend over and deftly grab it with my left hand wondering if I am going to be bitten. I cover it with my right hand and swirl it around in less turbid water. I take a look. I have grabbed what looked to me to be a small lobster – about 5 inches long. It’s a crayfish – often call a crawfish, crawdad, or mudbug. I wonder if it’s going to pinch me.

“Hey take a look at this!”

“What is it? Can I touch it? Will it bite me?”

I hold it by the sides of its abdomen so it won’t pinch me and I let her touch it. She then wants to hold it. Of course, she wanted to save it but I said she needed to put it back. She held it delicately – neither of us got pinched.

“Let’s find some more.”

We tried for a while but without success. We turned our sole victim loose, both realizing that we were lucky to have found the one specimen. Rivers are wonderful places for exploring. You never know what you’re going to find.

Of course, rivers can be dangerous, too, especially after a heavy rain. The first thing we all need to appreciate is the power of water. One should always go with a person who can swim and who can judge where and when to go in. Our rule is that a 4-year old always needs an adult for exploring a river. We have also discussed that water quality may not be good right after a rain, especially if we have any cuts on our bodies. It’s best to stay out for a few days till the water clears up. Surface runoff during storms can carry a lot of bacteria and pollution with it.


Nature Through a 4-year-old’s Eyes Explorer’s Club #1 – Lakes

I was out and about this summer and spent a fair bit of time exploring lakes. One of my companions on some of these jaunts was a 4-year old. This was great. She helped me see things in a whole new way.


Hey granddad, “What are all these squiggly lines?”

I waded out to where she was standing waist deep (her waist) in the cool, clear lake waters. I still had my glasses on so I bent over and waited for the ripples to subside. As the waters calmed, sure enough there were lines in the sand as if she had drawn them with a stick. They were 5 to 10 ft long and often looped back on themselves. I considered but dismissed hydrologic origins to these phenomena – the lines cut right across the ripple marks on the lake bottom. I started wondering what creature could have done this pattern in the sand.

“Look, they are all over the bottom. What are they?”

The more I looked, the more I came to believe they were tracks. We had seen snails the day before and also small intricately patterned water snakes. They were both interesting possibilities but not quite right. I looked more and more carefully at the lines as she became more animated and started churning up the water, her energetic side overtaking her scientific interest in our discovery.

The flashes of light from her frolicking reflected off shiny nubs at the end of several of the lines. I reached down and scooped up a handful of sand, silt, and pebbles.

As I watched the sand and silt sift through my fingers, I discovered something larger left in my hand.

“Hey, come look at what I found.” She came over wide-eyed, splashing me in the process.

DSCN0810-305px“What is it? What did you find?” She asked. I opened my hand and showed here a bluish-black mussel about two inches across, with a shiny nubby hinge on one side.

“It’s a mussel,” I said.

“I can make a muscle.” She flexed here bicep, grinning ear to ear.

“Not that kind. This is what we call a shellfish. A bi-valve. It has two shells. It moves by filtering water and sand through the edges of their shells. That process propels it along the bottom, leaving these tracks behind. Let’s put several in a bucket for a few minutes and see what happens.”

We put 2 inches of sand and 6 inches of water into a bucket and placed 2 mussels, lying flat on their sides on top of the sand. We then put the bucket in the shade sitting in a few inches of water to keep it cool.

Nothing happened while we watched so she was off exploring other things. Five minutes later we took another look and found both mussels to be standing on edge and puffing water out of their shells.

“They are making tracks in the sand in our bucket! Let’s put some more in.”

She was right. They had already made 4-inch long tracks in the sand. We had tested and proven our theory that these mussels had created at least some of the tracks that we had discovered. She was excited about her discovery.

Someday she will ask more questions about some of these discoveries. She will learn that mussels are important filter feeders that help keep our lakes and rivers cleaner. We did ask the locals about eating them but were discourage from doing so for two reasons. First, they are not as tasty as their saltwater relatives. Secondly, since they are long-lived filter feeders, pollutants from the burning of fossil fuels and storm water runoff that settle to the bottom of our lakes, can build up inside them making them distasteful and potentially harmful. That put a slight damper on things for me.

But we loved talking about our discovery of the day, amazed at how easy it was to discover something new to us, simply by exploring nature.


Can Fiction Save Our Climate?

monkey wrench gangScientists deal in the non-fiction world most of the time. We want to ask questions, collect data, make tentative interpretations, and then test these theories. It’s the old scientific method that has worked so well for creating our modern world. But sometimes it’s too hard to explain the complex details of science and technology to everyone and debate can devolve into a matter of who do you believe.

Can fiction help us in those situations?

Dicken’s prose is lauded for exposing the ugly underbelly of 19th century industrial England. Sinclair Lewis exposed the meat packing industry and the horrid conditions of labor in the United States. Orwell showed what man is capable of doing to his fellow man with his demagoguery. All were and are powerful works of art that exposed our darkest moments.

In looking at the environmental literature, there are landmark non fiction pieces such as Silent Spring, The End of Nature, Collapse, and Earth in Balance. But it’s harder to select nominations for the Great American Novel that deals with climate change. The best known pieces of eco-fiction (or Cli-Fi ..climate fiction) include Flight Behavior, The Water Knife, Odds Against Tomorrow, and Oryx and Crake. But these touch on future dystopian worlds or singular elements of a warming climate.

The most classic novel that reflects the anger many  have in response to unrestrained growth is The Monkey Wrench Gang (1975) by Edward Abby. It’s about a small group of people who take into their own hands a campaign to stop the development/destruction of the canyonlands of Utah. As well written and entertaining as it may be, it has been blessed and cursed by it’s impact on decades of budding environmentalists.

Some claim it was the primer to the ecoterrorists of the 80s and 90s. Many of you may have forgotten but there were efforts to prevent the logging of old growth forests and the development of pristine habitats in the west. Some of these efforts were violent, most were not. Just before 9/11 President George W. Bush declared The Earth Liberation Front as  “The greatest terrorist threat in the country.” Then the towers went down and all our attention was focused on Al Qaeda.

I actually believe that Abby showed most of us how futile violence is in the long run and that his book launched a whole generation of advocates that have done a whole lot more working with the system than trying vigilante efforts to stop it. There have been many places preserved in this country since those dark days back in the 1970s when Abby wrote his treatise. In fact the whole environmental movement has matured and has become part of our culture.

Our trouble today is that our population continues to grow and so does consumption, and our overuse and abuse of fossil fuels. Our everyday activities are warming our oceans and our atmosphere. We need another wake up call that all of us will heed so we can all work together to tackle this climate challenge. I would love to see another piece of fiction stimulate a whole new cadre of people to take action to slow down the warming trend that is destroying the favorable climate that we all grew up in. Stay tuned.

Let me hear from you if you have other works of literature that have inspired you to take better care of our Earth.

Turkeys, Eagles, and Pileated Woodpeckers, Oh My!!

Not a bad day. Aside from bluebirds, gold finches, and cardinals fighting over my bird feeder this morning, a full grown pileated woodpecker landed on the top of the pole holding the feeder. He gave me a great display for at least 20-30 seconds. Fabulous.

I was then lucky enough to catch a bald eagle fly by and land in a tree this morning. so I decided to go for a walk and saw a turkey run across the path out of the wetlands by Lake Elkhorn. I had not seen one here in this green buffer before.

Not a bad day, indeed.

New Release – Coming of Age and Finding Your Place


Dunlop book-coming-of-age-smallGuest Post by Author Julie Dunlap

Growing up has always been tough. But the millennial generation, my young adult children’s cohort, faced especially daunting challenges. The 9/11 terror attacks, Hurricane Katrina, the BP oil spill, and SuperStorm Sandy, along with melting ice caps and bleaching coral reefs, have been formative events in their youths and childhoods, shaping their understanding of people and planet along with their maturing characters. As an environmentalist and a parent of four, I wondered and worried how early experiences of a shifting and troubled Earth may alter young adults’ attachments to place and the natural world.

To explore these questions, I joined with Anne Arundel Community College professor Susan A. Cohen (also a mom of two millennials) to collect essays by young writers grappling with growing up in an era replete with environmental and social crises. The result is a new anthology, published this month by Trinity University Press—Coming of Age at the End of Nature: A Generation Faces Living on a Changed Planet. The collection’s title alludes to Bill McKibben’s book, The End of Nature, published in 1989 before many of our contributors were born. In the 1990s, McKibben’s best-seller introduced me and millions of other then-young parents to the looming threats of climate change and humanity’s ubiquitous alterations of our basic natural systems.

Perhaps anger was the emotion I most expected at the project’s outset, and some Coming of Age contributors do rail against their earthly inheritance, against the losses imposed as forests shrink and oceans sully. Yet others question older generations’ ideas, rejecting the view that a tourist-thronged canyon is inherently compromised, and insisting that pristine wilderness need not be the ultimate definition of natural beauty. Many find ways to celebrate remaining pockets of tenacious nature, the return of raptors to urban parks, or the rejuvenation of community through sharing food foraged in the wild. And most heartening of all, woven through essay after essay, are feelings of love, of home, and of commitment to a thriving future. Far from the entitled laggards of media myth, these young people are seizing and creating opportunities to protest, study, plant, explore, build, teach, and of course write about the challenges they face and the solutions they foresee. McKibben, in his generous foreword to Coming of Age at the End of Nature, praises the essays as “mature, reflective, deep, and lovely,” but also and most of all “hopeful.”

Of course, I still wonder and worry about what lies ahead for my children and yours, as places and processes we knew to be timeless transform at an accelerating pace. But thanks to the youthful voices in this collection, I know the rising millennial generation has roots in their Earth, deep and wide, and the resilience to face whatever comes next.
