Michael Pollan: It's Time to Put Carbon Back Into the Soil
As the climate talks in Paris concluded, climate activists took note: soil restoration is our ally in the fight against global warming. It is inexpensive, effective and easy to implement, and it yields multiple benefits. Besides capturing carbon and reversing desertification caused by severe drought, soil restoration enhances regional cooling, strengthens resilience against droughts and floods, and improves food quality. It is a necessary second front in our battle against the heating up of Earth’s atmosphere.

How so? Soil holds carbon—lots of it. Other than the oceans and fossil fuel deposits, soils are the largest reservoirs of carbon on the planet, holding approximately two times the amount in the atmosphere and vegetation combined. The dark color of fertile soil comes from the presence of organic carbon compounds.
Unfortunately, over the centuries, a great deal of carbon has been released from soils through both primitive and modern agriculture. The Intergovernmental Panel on Climate Change recognizes that reducing emissions alone will not stop global warming. Disruptions, it says, are “irreversible” unless there is a “large net removal of CO2 from the atmosphere over a sustained period.”
The good news is that what has been lost can be returned. The excess atmospheric carbon creating anxiety would be far more content in cozy soil. Photosynthesis is how it will get there, through the process whereby plants convert carbon in the air into organic molecules exuded by roots to feed hungry microbes underground.
Ohio State University Scientist Rattan Lal referred to soil restoration as “low hanging fruit” and says it can serve as a “bridge” to climate safety during the transition to a non-fossil fuel economy. In a 2014 white paper, the Rodale Institute showed that regenerative organic farming could capture carbon dioxide in quantities exceeding global emissions.
Indeed, soils are the only suitable reservoir for the excess carbon in the atmosphere.

Politicians are also taking note. France’s Minister of Agriculture Stéphane Le Foll has introduced a program, 4 per 1000, calling for a yearly increase of 0.4 percent in the amount of organic matter in the world’s agricultural soils. Scientific Director for the Environment of the French National Institute for Agronomical Research Jean-François Soussana claims this modest increase in soil carbon globally would be sufficient to offset global greenhouse gas emissions. Depending on how quickly the agricultural community responds, the atmospheric level of CO2 could be kept from rising to levels uniformly viewed as disastrous. At last count, 25 countries, including Australia and the U.K., have announced their commitment to this campaign.

Michael Pollan, author of New York Times best seller, The Omnivore’s Dilemma, calls on his faithful to heed this message. In a powerful new video, Soil Solutions to Climate Problems, he says, “When soil is damaged, it releases carbon dioxide into the atmosphere and this has had serious consequences for the climate.” He then offers the “good news: we now know how to put carbon back in the soil where it belongs … What had been atmospheric carbon, a problem, becomes soil carbon, a solution.”
Michael Pollan is right. Soil is a fix, but not just for climate. Restoring soil also ameliorates desertification, a factor that can destabilize already volatile regions. Consider the unprecedented drought—perhaps exacerbated by global warming—that precipitated civil unrest in Syria before the outbreak of civil war there.
We need look no further than the ground beneath our feet in our quest for a more verdant, peaceful world. Let’s embrace this convenient truth.

Winter is supposed to be the best season for wind power – the winds are stronger, and since air density increases as the temperature drops, more force is pushing on the blades. But winter also comes with a problem: freezing weather.

Ice buildup changes air flow around the turbine blade, which can slow it down. The top photos show ice forming after 10 minutes at different temperatures in the Wind Research Tunnel.

While traditional investment in the ocean technology sector has been tentative, growth in Israeli maritime innovations has been exponential in the last few years, and environmental concern has come to the forefront.
theDOCK aims to innovate the Israeli maritime sector. Pexels<p>The UN hopes that new investments in ocean science and technology will help turn the tide for the oceans. As such, this year kicked off the <a href="https://www.oceandecade.org/" target="_blank" rel="noopener noreferrer">United Nations Decade of Ocean Science for Sustainable Development (2021-2030)</a> to galvanize massive support for the blue economy.</p><p>According to the World Bank, the blue economy is the "sustainable use of ocean resources for economic growth, improved livelihoods, and jobs while preserving the health of ocean ecosystem," <a href="https://www.sciencedirect.com/science/article/pii/S0160412019338255#b0245" target="_blank" rel="noopener noreferrer">Science Direct</a> reported. It represents this new sector for investments and innovations that work in tandem with the oceans rather than in exploitation of them.</p><p>As recently as Aug. 2020, <a href="https://www.reutersevents.com/sustainability/esg-investors-slow-make-waves-25tn-ocean-economy" target="_blank" rel="noopener noreferrer">Reuters</a> noted that ESG Investors, those looking to invest in opportunities that have a positive impact in environmental, social and governance (ESG) issues, have been interested in "blue finance" but slow to invest.</p><p>"It is a hugely under-invested economic opportunity that is crucial to the way we have to address living on one planet," Simon Dent, director of blue investments at Mirova Natural Capital, told Reuters.</p><p>Even with slow investment, the blue economy is still expected to expand at twice the rate of the mainstream economy by 2030, Reuters reported. It already contributes $2.5tn a year in economic output, the report noted.</p><p>Current, upward <a href="https://www.ecowatch.com/-innovation-blue-economy-2646147405.html" target="_self">shifts in blue economy investments are being driven by innovation</a>, a trend the UN hopes will continue globally for the benefit of all oceans and people.</p><p>In Israel, this push has successfully translated into investment in and innovation of global ports, shipping, logistics and offshore sectors. The "Startup Nation," as Israel is often called, has seen its maritime tech ecosystem grow "significantly" in recent years and expects that growth to "accelerate dramatically," <a href="https://itrade.gov.il/belgium-english/how-israel-is-becoming-a-port-of-call-for-maritime-innovation/" target="_blank" rel="noopener noreferrer">iTrade</a> reported.</p><p>Driving this wave of momentum has been rising Israeli venture capital hub <a href="https://www.thedockinnovation.com/" target="_blank" rel="noopener noreferrer">theDOCK</a>. Founded by Israeli Navy veterans in 2017, theDOCK works with early-stage companies in the maritime space to bring their solutions to market. The hub's pioneering efforts ignited Israel's maritime technology sector, and now, with their new fund, theDOCK is motivating these high-tech solutions to also address ESG criteria.</p><p>"While ESG has always been on theDOCK's agenda, this theme has become even more of a priority," Nir Gartzman, theDOCK's managing partner, told EcoWatch. "80 percent of the startups in our portfolio (for theDOCK's Navigator II fund) will have a primary or secondary contribution to environmental, social and governance (ESG) criteria."</p><p>In a company presentation, theDOCK called contribution to the ESG agenda a "hot discussion topic" for traditional players in the space and their boards, many of whom are looking to adopt new technologies with a positive impact on the planet. The focus is on reducing carbon emissions and protecting the environment, the presentation outlines. As such, theDOCK also explicitly screens candidate investments by ESG criteria as well.</p><p>Within the maritime space, environmental innovations could include measures like increased fuel and energy efficiency, better monitoring of potential pollution sources, improved waste and air emissions management and processing of marine debris/trash into reusable materials, theDOCK's presentation noted.</p>
theDOCK team includes (left to right) Michal Hendel-Sufa, Head of Alliances, Noa Schuman, CMO, Nir Gartzman, Co-Founder & Managing Partner, and Hannan Carmeli, Co-Founder & Managing Partner. Dudu Koren<p>theDOCK's own portfolio includes companies like Orca AI, which uses an intelligent collision avoidance system to reduce the probability of oil or fuel spills, AiDock, which eliminates the use of paper by automating the customs clearance process, and DockTech, which uses depth "crowdsourcing" data to map riverbeds in real-time and optimize cargo loading, thereby reducing trips and fuel usage while also avoiding groundings.</p><p>"Oceans are a big opportunity primarily because they are just that – big!" theDOCK's Chief Marketing Officer Noa Schuman summarized. "As such, the magnitude of their criticality to the global ecosystem, the magnitude of pollution risk and the steps needed to overcome those challenges – are all huge."</p><p>There is hope that this wave of interest and investment in environmentally-positive maritime technologies will accelerate the blue economy and ESG investing even further, in Israel and beyond.</p>
