Leaf Story

Yesterday I spent the better part of the afternoon outside. What I was doing was not as enjoyable as a good, long hike in the autumn woods with the crunch of leaves beneath my feet. There was the crunch of leaves, but I was raking them and moving them. In my small city, we can rake the leaves to the curb for pickup by the city. It’s nice to be able to do put the leaves at the curb instead of bagging them. That is one of the reasons I enjoy living in the City of Fairfax.

But I remember the time in which the cool Fall air would be mixed with the rich smell of burning leaves. In the Fall, in towns where I grew up, small piles of leaves would dot the yards. Those small piles were often burned in place by the property owner. Or the leaves might have been swept to the curb or edge of the street to be burned. Sometimes a brick bbq pit would be used as a leaf furnace. Every yard had a least one, round, burn circle somewhere in the back. But those days are behind us, and for good reason. The smoke from the many piles of leaves, especially as towns grew and suburbs sprawled, became a choking haze over the houses and the city. The Fall air is cleaner now, and I do not miss the times of dense smoke. But I can remember the sights and the rich, sweet smell that rose up from the fires of our small piles of leaves and fallen twigs.

They were like camp fires. We would gather around the pile and watch as the tongues of flame crept through its depth. We would then stand guard to make sure the fire did not go beyond the pile of leaves and its burn circle. There was always a bucket of water at hand in case the grass began to burn, and maybe a hose if one was available. It was a family event. My parents or my grandmother would be around, and my brother and my cousins and I would poke at the small fire and stare into its flame. We would talk about our lives and dream aloud of our future. It was a time together.

The finest picture I have seen of this is the one by John McCutcheon which he drew in 1907 for the Chicago Tribune. A young boy stands and stares into the smoke while his grandfather relates a tale of years gone by. The language has fallen into disuse, but I believe the sentiments expressed are strong and valuable and worthy of remembering.

There were people who lived on these lands long before the Europeans came. They and their children held the land as sacred. They knew and kept the value of family. They respected the people that had lived on the land before them and who had passed forward the land rich with life. These people also looked with hope into their future.

John McCutcheon’s cartoon and text are no longer published. But each year about this time after I have been raking and preparing the garden with an eye to Spring, I take out my yellowed copy of the art with its history and read it again. And I thank all of the people that lived on this land before and who worked to care for the land and the water and the air so that it might remain a place of beauty. It is a place to remember.

Reef Protector

I had to decide if I wanted to title this post “KILLER ROBOT” or “Reef Protector”. The two different titles convey very different images, one quite provocative as a hunter/killer, and bringing to mind an endless stream of science fiction movies. I chose “Reef Protector”. It brings to mind a quest, and a hero who takes on the challenge. I had already designed the art of a killer robot but added a shield to make it less so – an assassin and a protector.

The Great Barrier Reef Foundation (GBRF) in Brisbane, Queensland, Australia, https://www.barrierreef.org/the-foundation,  launched a protective program to defend the Great Barrier Reef against a voracious predator,the Crown of Thorns starfish. This predator is one of the greatest challenges facing the survival of the Great Barrier Reef. Other threats to the Great Barrier Reef include climate change, disease, changes in ocean chemistry, rising ocean waters, pollution, and physical destruction of portions of the reef by fishing gear and boat propellers. These economically valuable and beautiful reefs are threatened wherever they are.

I have not seen any part of the Great Barrier Reef, but I have dived on smaller reefs in the Philippines and in Florida where corals have created habitats for a myriad of other species. I plan on visiting the Great Barrier Reef, but this creates a challenge as well. When I get there I have to ensure that my presence and my activity does not further damage or destroy any part of this magnificent natural wonder. I say that not just as an individual wanderer, but as one of many people who visit the area. We all must ensure that tours and dives we take and services that are provided to us allow for sustainable use and protection of the Great Barrier Reef.

If the Great Barrier Reef were a single organism, it would be the largest living organism on the planet. It is of course a massive natural wonder that is made of countless individuals from a myriad of species,including many fragile and beautiful corals. However, in lore and in stories a coral reef is considered a danger which can crush the hulls of massive ships and tear small boats apart. How can a fragile thing be so dangerous and tear apart the strongest steel? The coral in the coral reef is a tiny animal. The National Oceanic and Atmospheric Administration’s (NOAA) website, https://coralreef.noaa.gov/,  describes the coral animals, called polyps, as being between one and three millimeters across. That means that in the space of an inch, depending on the type of coral, between eight polyps and 25 polyps could exist. A five-inch line of type could span more than 100 polyps. The coral polyps create hard shells out of minerals in the sea water and live in closely packed colonies. When the polyps die their tiny skeletons remain behind along with those of its generation. These skeletons form the base for the following generations of corals to grow on. Over thousands of years these tiny polyps build up into massive reefs of incredible bulk and mass. It is this stony calcium carbonate base that has the mass to tear ships apart.

The Great Barrier Reef is made up of not just the uncountable individual coral polyps but of a huge number of intertwining coral reefs that have built up over the millennia. These reefs provide shelter for undersea communities that form the basis of the vast food webs of the warm tropical waters in which the majority of reefs are found. The reefs provide protection for the land on their inward side as they break the force of the ocean storms as the waves cross over the reef. In adddition, they are a living ecological community of incredible beauty.

The GBRF is working to protect the Great Barrier Reef. As part of their effort the RangerBot program was launched in 2015. Initially and provocatively described in the press, these robots were programmed to find and kill the Crown of Thorns starfish. The Crown of Thorns eats away at the corals and destroys much of the coral community. Without the living corals the other members of the undersea environment living on the reef were deprived of its benefits and either died or migrated to find other living coral reefs  that could provide them with a habitat. And of course, the Crown of Thorns would be there too.

Because of nutrient runoff from farms and homes into streams that feed rivers whose waters flow out to and over the Great Barrier Reef, the population of the Crown of Thorns starfish has grown significantly. With this population growth, their capacity to destroy large portions of the Great Barrier Reef has also escalated. To fight this increasing threat the RangerBot program was launched to seek out, optically identify, and kill the Crown of Thorns starfish with a killing agent. But this is not the only capability of the RangerBot. It is described on the GBRF website as a “Swiss-Army knife” for reef protection. The RangerBot was developed by the Queensland University of Technology (QUT) as an autonomous, underwater vehicle which can provide a “ranger-like” presence in the coral reef, day and night. It is a new set of eyes and hands for reef managers. It not only can help control the Crown of Thorns, but it can also be used to monitor the health of the reef. A planned modification of the RangerBot will assist in the spread of new coral polyps. The RangerBot will collect millions of spawn from the corals. After the spawn has been raised to a larval stage in large tanks, the RangerBot will return them to the reefs and spread them in an effort to rejuvenate the damaged reefs.

Hooray for the good guys!

Hippopotamus Virginicus

 

There is a road that cuts through the rolling hills of Virginia’s piedmont that I travel several times each year. I generally take this road at the end of a trip up and down interstate highways when I have gone off to visit family. The road is relaxing after the hubbub of the interstates, and the area that it goes through is enjoyable. It has vistas of rolling hills both as pasture and as woodland. It goes through villages that have not overgrown to the point that they need more than one stop light. It passes farm ponds and mountain streams. But you have to look out for the wildlife. A deer may burst from the woods. A fox may be seen crossing an open area. And the squirrels will challenge you as they dash back and forth across the road. But that’s about all you will see. These are the animals that have learned to abide close to the houses and farms we have built. But I very seldom see a bob-cat or a bear – or a hippopotamus. What?

Sure enough in my last passage along this road I looked up into a manicured area that led to someone’s house, and there next to the stream was a hippopotamus. It large shiny shape was unmistakable. Its massive jaw jutted outwards from its rotundity as it seemed to be moving from the water up the slight hill towards the house.

I had to turn around. I had to take a second look. I could not believe that there was a real hippo wandering these Virginia woods, or that someone had a life size hippo lawn ornament. After making a safe and legal U-turn I drove past the lawn again. And then again as I returned to my original direction. As I had surmised it was a lawn ornament. But what a lawn ornament, it was a full size bronze hippopotamus walking up that manicured lawn.

To me this was a recognition by the land owner of the changing relationship between us – all of humanity – and the creatures with whom we share this planet Earth. It’s not just with the Hippopotamus. It’s how our relationship is changing with all species, each of which has a place in the order and manner of life on earth. This changing relationship is not focused on species that are threatened or endangered or on a species that has moved out of its historical range and is now in our back yard. It’s our relationship with all of them; the hippopotamus, the elephant, the white-tailed deer, the northern bob-white quail, the mountain blue bird, the indigo snake, the desert gecko, the snow leopard. Its about how we and all the animals will coexist in the future.

Rules of location and use have been shattered in the last century. Wild populations have been destroyed and other species have moved in and replaced them. Or a species may explode in numbers when a natural predator is removed. Frogs die; Insects swarm.

But our relationship is shifting from a cohabiter of Earth to that of being the one species that must become the steward of all. We are the ones who have the capacity and the means to provide or withhold. We can enhance or destroy. We all must be aware of our role in the Earthly environment and the effect that we do have on local and on distant species.

Be aware. As frogs die, crops may be destroyed and disease may be spread.

I will look for this single Hippopotamus Virginicus when I drive down that road in the future. For me and for all of us it should be a reminder that we are caretakers, not owners.
