Lack of Energy Strategy = Doomsday for Future Generations
Feeding our energy appetite is top of mind for many people these days. Some argue we should get coal, oil and gas out of the ground as quickly as possible, build more pipelines and make as much money as we can selling it here and abroad. Their priorities are the economy and meeting short-term energy needs so we can live the lives to which we’ve become accustomed.
Many others question those priorities. Do we gain comfort and happiness by driving inefficient automobiles, buying and scrapping and then buying more stuff that we must work harder to pay for, and selling resources to enrich the fossil fuel industry and to allow other countries to follow our unsustainable path?
Some governments and industry favor the short-term view. But it’s a “false economy”—it will cost us more in the long run. What about our children and grandchildren and their children and grandchildren? Do we not want them to live healthy and happy lives? If we pollute the air, water and soil that keep us alive and well, and destroy the biodiversity that allows natural systems to function, no amount of money will save us.
While rushing to exploit our valuable and diminishing fossil fuels, Canada’s government is simultaneously “streamlining” environmental regulations and review processes, cutting scientific staff and departments and limiting public debate on projects that could irreparably damage our rich natural heritage. Some provinces are attempting to water down hard-won environmental laws, like endangered species legislation, that act as a critical hedge against environmental degradation.
The federal government is also neglecting its legal obligations to protect species at risk. Ecojustice, on behalf of five conservation groups including the David Suzuki Foundation, recently launched a lawsuit to challenge the government’s multi-year delays in producing recovery strategies for species that would be affected by the proposed Enbridge Northern Gateway project.
If we don’t slow down and try to look at ways out of the mess, energy issues will continue to increase, like the Hydra of Greek mythology. With pipelines, the main issue is rapid tar sands expansion. But other massive energy projects are also coming down the pipe—from huge dams, like the Site C in northern B.C., to proposed drilling for oil and gas in the Gulf of St. Lawrence and the Arctic. To what end?
Not only are fossil fuel companies making record profits, they’re being subsidized by Canadian taxpayers to the tune of $1.4 billion a year. Instead of giving them money, shouldn’t we be compelling them to put at least a small portion of their enormous profits into reducing the massive greenhouse gas emissions they cause?
A large part of the problem is that we are increasing our fossil-fueled ambitions at breakneck speed in the absence of a national energy strategy. No one seems to know where we’re going, but the end of the road is looming, and it might lead to a steep drop. We’re already harming precious ecosystems and are ready to put even more at risk without having an idea of the often irreplaceable value they represent. With climate change and its impacts, along with deforestation, pollution and increasing urbanization, we’re condemning millions of people to lives of poor health, desperation and even death.
Still, we’ve also created much that is good. We have political systems that encourage public debate and access to information. There are politicians and industry leaders who have joined countless citizens, First Nations, and environmental, labour and social-justice organizations to question current policies and actions. We have science, medicine and technology that have allowed many of us to live longer. We need to find ways to reconcile our existence with the limits of our finite planet.
What Canada really needs in the short term is a national energy strategy—one that goes beyond fracking and tar sands and pipelines to take into account these many other factors, including wiser use of fossil fuels. It must help us make the transition from our wasteful addiction to polluting and ever-diminishing fossil fuels to conservation and renewable energy. Globally, we need to shift from the outdated 20th-century notion of measuring progress with gross domestic product to a development paradigm that takes into account well-being and happiness, and that accounts for nature’s valuable services.

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>
