The science and technology that can help save the ocean

Here on Earth, we have more detailed maps of Mars than of our own ocean, and that’s a problem. A massive force for surviving climate change, the ocean absorbs 90% of the heat caused by emissions and generates 50% of the oxygen we breathe. “We have the ocean to thank for so many aspects of our safety and well-being,” says Dawn Wright, oceanographer and chief scientist at geographic information system (GIS) provider Esri, who notes the ocean also provides renewable energy, a major food source, and a transportation corridor for not only ships but submarine internet cables.

Now, the same type of smart maps and geospatial technology guiding outer space exploration support the quest to better understand and protect our ocean. “For the first time, our knowledge of the ocean can approach our knowledge of the land,” Wright says. “We can turn the unknown deep into the known deep.”

‘The Dispossessed’ Is Still One of Sci-Fi’s Smartest Books

Ursula K. Le Guin’s 1974 novel The Dispossessed depicts a society with no laws or government, an experiment in “nonviolent anarchism.” Science fiction author Matthew Kressel was impressed by the book’s thoughtful exploration of politics and economics.

“After reading The Dispossessed, I was just blown away,” Kressel says in Episode 460 of the Geek’s Guide to the Galaxy podcast. “It was just such an intellectual book. It’s so philosophical, and it was so different from a lot of the science fiction I had read before that. It made me want to read more of Le Guin’s work.”

Science fiction author Anthony Ha counts The Dispossessed as one of his all-time favorite books. “I would be hard pressed to think of another novel that made as strong an impression on me,” he says. “I was insufferable about it. I put quotes in my email signatures, and I identified as an

Print book sales up in games, education, and thrillers in 2020: BookNet report

The story of print book sales in Canada in 2020 in some ways mirrors the story of the ongoing COVID-19 pandemic: print book sales were down overall, but some categories, including games, education, and thrillers, saw a rise in sales last year, according to the latest research from BookNet Canada.

BookNet’s annual market overview, The Canadian Book Market 2020, was released this week. The report found that although the value of print-book sales was down 5.3 per cent from 2019 when using a set of comparable stores, certain categories saw growth from the previous year. 

In an echo of the pursuits Canadians turned to when they were stuck indoors for a months-long lockdown last spring, English-language books in categories such as games, education, and thrillers saw a rise in sales.

In another reflection of the pandemic’s effects on daily life, print book sales were down more than 40
