The Unintended Consequences of Giving Water
In war, natural disaster and poverty, water is the first relief to arrive alongside the security of life and limb. It is the gift that aids the weary traveler, sits at the table before a meal arrives. The lack of it kills before the lack of food does. It is not a commodity, as in the Bolivian Water Wars that fought the privatization of public wells, but rather it is a human right. So when the United Nations sanctions against Iraq in the 1990's stressed schools and hospitals to the point of disrepair and abandonment of their wells, human rights activists stepped in.
In 1999 a group of veterans, working through Veterans for Peace, founded the Iraq Water Project, with a mission to improve the health prospects of some part of the Iraqi population dependent upon water treatment facilities in desperate need of repair. Once a site is selected, usually a school or clinic, a 3-stage filtration unit, with reverse osmosis and ultraviolet light treatment, is set up to clean incoming water from a river, well or municipal source.

To date, 160 units are in place mostly in schools and clinics across Iraq. We've installed one filter unit in an orphanage, a refugee camp, six prisons, including Abu Ghraib, which is now closed, and the alAskari shrine in Samarra, the one that alQaida bombed back in 2006.
Our partner, Muslim Peacemaker Teams, installed five units in Najaf schools, while Life for Relief and Development, an American Islamic NGO, installed two units in schools in the Diyala Province (east-central Iraq). For reasons of security we cannot name the group we work with in Nassiriya that installed four water treatment units in the new Nassiriya Heart Center and another four in local schools. These organizations are doing the lion's share of the work, taking responsibility for the installation, security and maintenance of the water filter units, providing citizens with a basic human right—access to clean water.
What's come of this investment are positive unintended consequences that have exceed our expectations, both social justice and conservation. By contributing to the relief of someone's suffering, a wonderful sense of humility and joy emerges, especially among the U.S. veterans participating in the project, which I can attest to personally. More importantly, lives are saved, dysentery among small children and water-borne illnesses have been reduced where the water filters are installed. Unexpectedly, the water filters serve not only the schools and clinics, but they become a community hub—a meeting place. The goodwill that emerges from Iraqi organizations managing their own recovery and the relationship that forms between Iraqis and American citizens is invaluable. There is reconciliation and atonement, which are hard to find.

Interestingly, giving water contributes to solving another problem: plastic pollution. Often when relief aid is sent after a natural disaster or during civil unrest, it comes packaged in stuff that becomes garbage. Water bottles by the millions are strewn across villages in Iraq, reflective of the years of poor waste management, garbage from war and relief aid. American bases established in Iraq employed "burn pits" to incinerate garbage. The same burn and bury strategy exists in villages across the country, sending acrid smoke into communities. Iraq's waste problem contributed to public outbreaks in cholera and dysentery, and roadside bombs found ample trash piles to be concealed within.

One water filter can sustain daily drinking water for 1,000 residents for up to 3 months before filters need to be changed. The same volume would exceed half a million 1 liter plastic water bottles. By providing the "means to fish, rather than the fish itself," access to water becomes seemingly endless. But in today's political climate in Iraq, there are continued challenges to keep these water filter units operational.
Therefore, what continues today is maintenance and new installations of water filter units where they are needed. We recognize that past sanctions, war and poverty, exacerbate suffering, but sharing this gift is contributing to Iraq's recovery in sometimes unpredictable ways. It all begins with water.

A chance discovery of a beautifully preserved fossil in the desert landscape of Morocco has solved one of the great mysteries of biology and paleontology: how starfish evolved their arms.
The Pompeii of palaeontology. Aaron Hunter, Author provided<h2></h2><p>Although starfish might appear very robust animals, they are typically made up of lots of hard parts attached by ligaments and soft tissue which, upon death, quickly degrade. This means we rely on places like the Fezouata formations to provide snapshots of their evolution.</p><p>The starfish fossil record is patchy, especially at the critical time when many of these animal groups first appeared. Sorting out how each of the various types of ancient starfish relate to each other is like putting a puzzle together when many of the parts are missing.</p><h2>The Oldest Starfish</h2><p><em><a href="https://www.biorxiv.org/content/10.1101/216101v1.full.pdf" target="_blank" rel="noopener noreferrer">Cantabrigiaster</a></em> is the most primitive starfish-like animal to be discovered in the fossil record. It was discovered in 2003, but it has taken over 17 years to work out its true significance.</p><p>What makes <em>Cantabrigiaster</em> unique is that it lacks almost all the characteristics we find in brittle stars and starfish.</p><p>Starfish and brittle stars belong to the family Asterozoa. Their ancestors, the Somasteroids were especially fragile - before <em>Cantabrigiaster</em> we only had a handful of specimens. The celebrated Moroccan paleontologist Mohamed <a href="https://doi.org/10.1016/j.palaeo.2016.06.041" target="_blank" rel="noopener noreferrer">Ben Moula</a> and his local team was instrumental in discovering <a href="https://www.sciencedirect.com/science/article/abs/pii/S0031018216302334?via%3Dihub" target="_blank" rel="noopener noreferrer">these amazing fossils</a> near the town of Zagora, in Morocco.</p><h2>The Breakthrough</h2><p>Our breakthrough moment came when I compared the arms of <em>Cantabrigiaster</em> with those of modern sea lilles, filter feeders with long feathery arms that tend to be attached to the sea floor by a stem or stalk.</p><p>The striking similarity between these modern filter feeders and the ancient starfish led our team from the University of Cambridge and Harvard University to create a new analysis. We applied a biological model to the features of all the current early Asterozoa fossils in existence, along with a sample of their closest relatives.</p>
Cantabrigiaster is the most primitive starfish-like animal to be discovered in the fossil record. Aaron Hunter, Author provided<p>Our results demonstrate <em>Cantabrigiaster</em> is the most primitive of all the Asterozoa, and most likely evolved from ancient animals called crinoids that lived 250 million years before dinosaurs. The five arms of starfish are a relic left over from these ancestors. In the case of <em>Cantabrigiaster</em>, and its starfish descendants, it evolved by flipping upside-down so its arms are face down on the sediment to feed.</p><p>Although we sampled a relatively small numbers of those ancestors, one of the unexpected outcomes was it provided an idea of how they could be related to each other. Paleontologists studying echinoderms are often lost in detail as all the different groups are so radically different from each other, so it is hard to tell which evolved first.</p>

Industry would have us believe that pesticides help sustain food production — a necessary chemical trade-off for keeping harmful bugs at bay and ensuring we have enough to eat. But the data often tell a different story—particularly in the case of neonicotinoid pesticides, also known as neonics.
