16-Year Study Blames Pesticides for Significant Sperm Decline
Until better protections are in place, anti-pesticide experts suggest supporting organic agriculture as a method of avoiding exposure to these dangerous chemicals.
The study, which first published its findings in 2012 and has now been refined, found that sperm counts across France had plummeted 30 percent in 16 years, and noted those living in mainly rural regions of southwest France had been most affected, reports Connexion—France's English-language newspaper.
The affected regions, Aquitaine, Burgandy and Midi-Pyrenees, contain the highest concentration of farms in the country and subsequently rely heavily on agriculture for their economies.
The authors of this latest study, led by Dr Joëlle Le Moal at the The Health Watch Institute, suggested a link between declining sperm count and higher exposure to pesticides in an agriculture-based economy.
The wine industry, they noted, is “where the most pesticides are used in proportion to the agricultural area."
They were able to remove alcohol and cigarettes as possible causes, because the most affected areas are not those where the consumption of tobacco and alcohol are highest, and said genetic factors could not explain the rapid rate of decline.
The original study, published in 2012, collected data from 26,600 men from 126 towns and cities across France who took part in medically assisted procreation programs between 1989 and 2005. This latest report comes after the initial program was refined to compare trends across 21 regions.
"It's very important to monitor the quality of sperm at the international level now that we have data about its degradation in France," said Le Moal.
A Problem for All Men
Beyond Pesticides, a national coalition against the misuse of pesticides, suggests U.S. men (and all nationalities) should be cautious as recent scientific literature reviews came to similar conclusions regardless of where a man calls home.
In a U.S. review, researchers counted semen quality according to concentration of sperm over an area, their motility and ability to move, as well as their shapes. What they found was striking: almost all the studies reported a decrease in sperm concentration; decreased motility was also reported though less frequently; and, while morphological changes were not strongly associated in studies—only two indicated any changes to sperm shape.
The French findings build on the now growing body of evidence that pesticide exposure at environmental or occupational levels diminishes sperm health. For many, the connection is an obvious one: endocrine disruption. Sperm production is regulated by the endocrine system, a highly sensitive form of hormone regulators. Pesticides in both high and low doses are potent endocrine-disruptors, meaning that they disturb this sensitive system that regulates many other bodily systems.
While the endocrine-disrupting effects of many pesticides have been documented, U.S. regulators have been extremely slow to move forward with the statutorily-mandated review of pesticides for the previously unevaluated risk of potential endocrine disruption. Yet, findings like Dr. Moal’s studies and many others highlight the importance of generating strong pesticide regulations that take into consideration endocrine disrupting effects when evaluating safety standards for worker protection and human health impact.
Until better protections are in place, Beyond Pesticides recommends supporting organic agriculture as a method of avoiding exposure to these dangerous pesticides.

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.

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>
