Meet Five 'Extinct' Species That Have Returned to Life
By Sean Fleming
As many as one million species of animal and plant could face extinction. This dramatic decline in the health of global biodiversity is a crisis in itself as well as a threat to the wellbeing of the planet's population, the UN warns. Plus, it poses a very immediate risk to global food security and economic activity.
Since the 16th century, hundreds of species of vertebrates have disappeared – almost all due to human-related changes such as loss of habitat or over-hunting. That threat remains present with around 40% of amphibians, 33% of marine mammals and 14% of birds all facing an uncertain future.
A quarter of all species are threatened with extinction. Statista
That said, there have been many notable conservation successes. There have also been several discoveries of animals that were believed to have become extinct. Here are five examples of what are often referred to as Lazarus species – breeds that have seemingly come back from the dead.
1. Elephant Shrew
The last time anyone recorded a sighting of the Somali elephant shrew was almost 50 years ago, after which, it was assumed to have become extinct. Then, in August 2020, a team of researchers and academics reported that these tiny, odd-looking creatures were alive and well. Also known as the Somali Sengi, this mouse-sized animal, with its distinctive elongated nose, is thriving across the Horn of Africa.
2. Terror Skink
In 1872, the French botanist Benjamin Balansa noted the discovery of a lizard while visiting the French Pacific territory of New Caledonia. At around 50cm (20 inches) in length, it probably wasn't too hard to spot. Yet, the terror skink – the 'terror' part of the name refers to its mouthful of rapacious teeth – was never seen again. Not until 2003, that is. Having been rediscovered by scientists, more research is now underway to learn more about them.
3. Cuban Solenodon
There are few venomous mammals in the world – the Cuban solenodon is one such example. But it was a missing example for some time. Although never technically extinct, its numbers are so low and sightings are so rare, that it has often been thought to be. The Cuban solenodon's forebears were around at the same time as dinosaurs: it is "a 'living fossil' that hasn't changed much in millions of years," according to the publication Scientific American. Its bite can kill yet it lacks the strength and dexterity to defend itself or flee from danger, making it an easy target for predators. Deforestation has also contributed to population disturbance.
4. Bermuda Petrel
The Cahow, or Bermuda petrel, was last seen on Nonsuch Island in 1620. But here in 2020, you can watch webcam footage of them. A small number of the birds were spotted nesting in the east of Bermuda in the 1950s, and the population has since been resurrected. The Cahow is a burrowing bird and much of its natural habitat has been destroyed by sea erosion and hurricane damage. New nesting sites were constructed by the Government of Bermuda, while chicks from established populations were relocated to Nonsuch, too.
5. Australian Night Parrot
Another elusive bird, the Australian night parrot, was thought to be extinct after the last recorded sighting in 1912. Then, in 1990, one was found in the state of Queensland. Sadly, it was dead. It would be another 23 years before a living example was spotted by a researcher. The precise location of that sighting was kept secret to protect the birds, whose populations are now closely monitored and who live in vast wildlife sanctuaries.

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>
