Anyone who reads the news today, whether on social media, newspapers, television, blogs, or whatever, is confronted with a litany of disastrous news about global warming, climate change, natural disasters, political crises, corruption, conflict and so on. True to the adage that good news is no news, there are few in-depth news stories about far-reaching events, running mostly in the background, that have potential to change the world. To give them credit, most news outlets nowadays are aware of this deficit and pepper their front pages with good news, most of which are one-offs; heart warming stories that are categorized as “human interest” stories. Don’t get me wrong. I love human interest stories, and devour them with my morning coffee. But they are not weighty enough to counter the leadbelly that results from reading the rest of the news. So how to counter that?
A perceptive listener once corrected me when I quoted: knowledge is power. No, they chided. Knowledge is only potential power. You have to do something with your knowledge to make it powerful. If you think about it, the converse holds true for bad news. Too much knowledge can be disempowering and reduce us to abject helplessness unless we do something about it. But what?
In an earlier blog entitled “Three score years and ten” I outlined a series of actions one can take to counter planetary leadbelly, beginning with baby steps. Meanwhile, here’s another link to a website that tells in-depth stories of people taking action around the planet to restore its health. Today, this particular story about Miyawaki Forests caught my eye. Tell your planetary gloom to take the day off. Follow the two links above, read, and enjoy.
The Covid-19 lockdown has put a damper on my scheme to sponsor the planting of at least 1000 trees in 2020. I hoped to plant a few of the thousand with my own hands. I think taking personal action leads to a deeper commitment.
There have been many articles recently about a Swiss company called CLIMEWORKS that has a strategy to remove CO2 from the air through conversion to carbonates. These carbonates can then store carbon underground as solids or else, in gaseous form, be treated to produce synthetic liquid fuels at an ultimate cost of around $ 1 per liter, as mentioned in a recent Nature Briefing newsletter.
Sequestering carbon with trees is much slower, less industrial, and would be Nature’s way to restore the planet. Following Nature’s way might be less glamorous to the uninitiated, but to be done well, it requires a wealth of local knowledge. This local knowledge is often the kind that is not found in text books or taught in schools. The kind of people who possess this knowledge usually do not know they possess something valuable, since much of the world discounts their knowledge for lack of paper qualifications, not even a high school diploma. But some of the most successful development programs have been based on inputs from aboriginals and “primitive” forest tribes. After all, artemisinin, cinchona and willow bark had been in use for centuries before modern medicine discovered them; artemisinin in China 2000 years ago, cinchona in early South American cultures. Willow bark and leaves were used by Assyrians, Sumerians, early Egyptians and ancient Greeks. So let’s plant trees then, as widely as we can, in order to suck up carbon. But if we make use of available local knowledge, we will find dozens, if not hundreds, of ancillary benefits.
One such afforestation program, conducted by a non-profit foundation called The Forest Way, strictly plants only indigenous species of trees on an area that covers a few square miles of once-barren land. In the twelve years since the planting began, a few dried out streams carry water again, leaf litter decomposing on the forest floor is slowly building up a layer of healthy soil and, most spectacular, the number of bird species sightings have increased from around 60 to 230+ at last count.
The subject of tree-planting brings me finally to the title of this post. ECOSIA calls itself an “ecological search engine” and it aims to help reforest the earth. According to Wikipedia, Ecosia plants an average of 1 tree for every 45 searches made on it. The Ecosia search engine works with all browsers and once you begin to use it, the page shows a small window with a tree symbol and a number to denote the searches made on this search engine since the download. Most recently Ecosia’s website reports 97 million trees planted (and counting), and more than 15 million users. Make that 15 million and one. I became an Ecosia user yesterday!
Chris Goodall (environmentalist, economist and businessman) has published a book in 2020 on recommended steps for a zero carbon future. In 12 concise and easily digestible chapters he outlines steps to be taken to achieve (or even exceed) the UN goal of stopping greenhouse gas emissions by 2050. Although specific to the UK, the straightforward proposals in the book could easily serve as a blueprint for any country around the world, regardless of where they stand on the spectrum of greenhouse gas emissions intensity.
The opening chapters deal with green energy generation to power local and regional grids, then move on to housing and transport. The chapters on transport deal with ground, air and shipping transport, three sectors that might need different fuels, depending on technological developments currently in their early stages; battery electric vehicles (BEVs) for ground transportation, hydrogen used with fuel cells for shipping, and liquid synthetic fuels for aviation. There are potential breakthroughs in the offing for each of these solutions and, of course, unforeseen developments in battery technology could mean that energy density is high enough for BEVs to power ships and airplanes as well as cars, buses and trucks. With so much potential waiting in the wings, this is an exciting time for new technologies, despite the looming threat of runaway climate change that can annihilate patterns of living we’ve developed over the past century.
There is a chapter devoted to fashion and its climate impact, as well as one on the carbon footprint of buildings, specifically in concrete production, and fossil fuels in heavy industry. There are known low-carbon solutions here, and the main problem is changing established production norms, the long lifetimes of existing physical infrastructure, and changing the mindset of the large corporations that own these industries.
Food production and forests have great potential to (one) reduce emissions and (two) absorb more CO2 respectively. Finally, it’s the economist’s turn to ask: how will all these changes be paid for? The straightforward answer is through a carbon tax that captures the environmental cost of the fuels used. However, experience has shown that the implementation of this straightforward answer is anything but. There are powerful vested interests to be overcome, not to mention the expense of retraining workers made redundant by obsolete industries.
Two chapters at the end of the book deal with direct air capture of CO2 and geo-engineering solutions. Each of these have their champions, but in my opinion, direct air capture (by industrial means) would never be cost-effective for a simple reason. The technologies that are sophisticated enough to make direct air capture cost-effective would also be good enough to lower emissions to the point where the technology is no longer needed. A sort of negative Catch-22. As for geo-engineering, the scales and money required for this effort would be best spent on researching and implementing technologies that lower emissions in the first place, rather than trying to decrease their effects. Secondly, there are too many unknowns associated with such large scale engineering projects. History is replete with examples of engineering hubris. The second half of the twentieth century saw countless predictions that “science would solve all problems” and “plentiful nuclear energy will provide power that is too cheap to meter.”
The final chapter, entitled “What can we do ourselves,” is more important than most people realize. On the one hand, individual actions do count and “little drops make an ocean.” But a second, little regarded effect of “little drops” will be the most important. Whether we live in democracies or dictatorships, ultimately, governments are guided by the cumulative wisdom of the governed. And in any nation where the overwhelming majority of its citizens practice sound environmental stewardship, this mindset will be inexorably transferred to the leadership as well.
We all know that leadership counts. We all realize intuitively that we get the leadership we deserve. So ultimately, logic stands on its head and we are forced to admit that we, the people, are the leaders who have to show our leaders the way.
