The Great Lakes hold 20 percent of the world’s fresh surface water. According to an article from Environmental Health News—Great Lakes Legacy Contaminants Decreasing, But Newer Ones on the Rise—legacy contaminants are decreasing more quickly than previously reported in three of the Great Lakes, but have stayed virtually the same in two other lakes, according to new research. Polychlorinated biphenyls (PCBs), the pesticide DDT and other banned compounds dropped about 50 percent in fish in Lakes Michigan, Ontario and Huron from 1999 through 2009, although there were no significant changes in Lakes Superior and Erie fish, according to the study to be published this month in Science of the Total Environment.
According to Environmental Health News, Thomas Holsen, co-director of Clarkston University’s Center for the Environment and co-author of the study, said:
“These are very positive results. The lakes are improving and slowly cleaning themselves up. Even with the decreases, it will be 20 to 30 years until the decades-old contaminants in Great Lakes fish decline to the point that consumption advisories can be eliminated."
All good news, except as we clean up the old chemicals like Polychlorinated biphenyls (PCBs), the pesticide DDT and other banned compounds they are being replaced by newer ones, such as flame retardants that are building up in fish and wildlife and chemicals we are not yet even looking for from oil and gas development.
Today, the natural gas industry is beginning horizontal hydraulic fracturing all around the Great Lakes to extract gas. It is against the law to frack under the lakes but there are no laws about fracking near streams, creeks, rivers that empty into the lakes. This is insane. Hundreds of toxic chemicals are injected under pressure into the ground to fracture the shale formation. Not all of these chemicals are retrieved after the fracking is done. In fact the common gas well leaves behind about 30 percent of the chemicals, radioactive materials and brine. It’s unbelievable, hundreds of chemicals injected all around our fresh water lakes that both the U.S. and Canada have worked for decades to clean up.
This destructive activity is a prime example of governments’ tunnel vision. Oil and gas development moves forward, cleanup of the lakes moves forward, air deposited of chemicals from many sources continues. It’s like shoveling the sidewalk in a blizzard, it won’t be cleaned until the snow stops falling. There is no sign of the chemical blizzards retreat.
I grew up near the lakes in Buffalo and understand their beauty and value. My sister and brother-in-law were active in advocating the cleanup of the lakes in the 1970’s. Our family vacationed on the lakes. It was exciting back then to hear that a serious effort from both sides of the boarder would advance to make the lakes swimmable, the fish safe enough to eat and so many other promises. Now more than 35 years later reports are praising the cleanup of historical chemical deposits while at the same time new chemicals are allowed to enter the lakes without protest.
Fracking is not yet widespread around the great lakes. Yes there are some wells in Pennsylvania, Ohio and Michigan, but we can stop widespread fracking that would further contribute chemicals to our beautiful lakes by taking a stand and insisting that regulations are put in place and bans where necessary to protect this amazing gift of nature. It is up you and me to make it happen.

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.
Comparing rime ice and glaze ice shows how each changes the texture of the blade. Gao, Liu and Hu, 2021, CC BY-ND
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>
