In railing against everything from bike lanes to transit spending, pundits and politicians often raise the spectre of a “war on cars.” Of course, there is no war on cars–but there should be.
Cars directly kill and hurt more people every year than most diseases, resulting in 1.5 million deaths and 78 million injuries needing medical care, according to the World Bank. Road injury is the eighth leading cause of death worldwide. Pollution from cars also causes acute and chronic health problems that often result in premature death–from heart disease and stroke to respiratory illness and lung cancer.

Environmental impacts of cars are also well-known and wide-ranging, including climate change, smog and oily run-off from roads, not to mention the green space sacrificed for infrastructure to sell, drive, fuel and park them. Despite fuel-efficiency improvements, emissions from vehicles have more than doubled since 1970, and will increase with rising car demand in countries like China, India and Brazil, according to the latest Intergovernmental Panel on Climate Change report.
Because many people, especially North Americans, can’t conceive of a world without cars for everyone, we overlook major problems caused by our private automobile obsession. We’re rightly outraged when a company like General Motors ignores faulty ignition switches in some of its vehicles, thought to have caused 13 deaths over 13 years. The massive recall that followed was justified and necessary. But as a headline on Treehugger’s website argues, “It's time for a bigger recall of a seriously defective product: The Car.”
The article continues, “Since we can't recall every car all at once and redesign the entire country, there are at least things we can do to make it less bad. Significantly reduce speed limits. Make drivers pay the full cost of infrastructure construction and maintenance through the gas tax. Build the cost of medical care for those millions of injured by cars into the price of gas. Invest in walkable cities and alternative forms of transport.”
Seattle newsweekly The Stranger, only somewhat tongue-in-cheek, created a 2011 manifesto for a real war on cars. “We demand that car drivers pay their own way, bearing the full cost of the automobile-petroleum-industrial complex that has depleted our environment, strangled our cities, and drawn our nation into foreign wars,” it says. “Reinstate the progressive motor vehicle excise tax, hike the gas tax, and toll every freeway, bridge, and neighborhood street until the true cost of driving lies as heavy and noxious as our smog-laden air.”
As Treehugger notes, we can’t shift from car-centric societies overnight. And until we find ways to better design our urban areas, many people will continue to rely on cars. After all, in the “developed” world, and increasingly in the developing world, we privilege private automobiles when creating infrastructure, often at the expense of what we need for public transit, walking and cycling.
Some even claim automobile and oil companies bought and dismantled streetcar and urban rail lines from the mid-1930s to the 1950s to sell more cars and oil. Fuel efficiency wasn’t a concern because, before pollution and climate change impacts were known, gas sale profits were a priority. Many factors were involved in the development of car culture, but we now find ourselves in an era when much of our oil is burned to propel mostly single users in inefficient vehicles.
Even with today’s improved fuel standards, only about 15 percent of the energy from each litre of fuel burned is used to move the vehicle, which typically weighs 10 to 20 times more than the passenger(s) it carries. That translates to about a one percent efficiency to move those passengers.
Although we can’t stop using cars altogether, we can curtail their damage to people and the environment. We can reduce greenhouse gas emissions by cutting back on car use, choosing fuel-efficient vehicles, joining a car pool or sharing program and reducing speed. At the policy level, we need increased investment in public transit and cycling and pedestrian infrastructure, stronger fuel-efficiency standards, reduced speed limits, higher gas taxes and human-centric urban design.
Besides combating pollution and climate change, reduced dependency on private automobiles will lead to healthier people, fewer deaths and injuries and livable cities with happier citizens. And that’s worth fighting for!

Sweden's reindeer have a problem. In winter, they feed on lichens buried beneath the snow. But the climate crisis is making this difficult. Warmer temperatures mean moisture sometimes falls as rain instead of snow. When the air refreezes, a layer of ice forms between the reindeer and their meal, forcing them to wander further in search of ideal conditions. And sometimes, this means crossing busy roads.

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>
