Why some scientists want to rebrand shark attacks as 'negative encounters' – CBC.ca

Dropping the phrase “shark attack” is a great way to change the narrative about the much-maligned sea creatures, says marine scientist Toby Daly-Engel.

Last week, the Sydney Morning Herald reported that scientists in two Australian states are moving away from that term in favour of more neutral language, like “bites,” “incidents” or “negative encounters.”

The story drew swift mockery online, as well as backlash from an organization that represents people who have been injured by sharks

But Daly-Engel, director of the Florida Tech Shark Conservation Lab, says we’re long overdue for a language shift when it comes to the misunderstood ocean dwellers, which are at a greater risk from humans than vice versa.

Here is part of her conversation with As It Happens guest host Susan Bonner. 

What do you make of the Australian decision to rebrand shark attacks?

I think it’s a really good step in the right direction, because for a long time we’ve known that [with] shark attacks, it really depends on people, not on sharks. And so trying to rebrand these interactions in a way that more accurately represents the event is really good as far as we’re concerned.

But this is being mocked quite a bit, especially the suggested terminology, “negative” shark “encounters.” Isn’t a shark attack sometimes just a shark attack?

Actually, most shark attacks are what we call provoked, meaning they are instigated by humans. And so the notion of a shark attack kind of conjures an attack out of the blue by some sort of mindless, bloodthirsty predator. And in reality, that’s not it at all.

Most things that get labelled by the media as shark attack are things like people poking sharks underwater, chumming where people are swimming or doing other things that really create a situation where somebody might be hurt by a shark. 

But the vast majority of these interactions are not actually due to the shark. And so the notion of shark attack, even though it’s the most recognizable terminology, it’s really inaccurate.

I guess, though, if a shark is biting you, whether it’s being called an attack or an interaction isn’t really the first thing on your mind.

Sure. But at the same time, in general, sharks have, in reality, way more to fear from humans than we do from them. 

Shark attack[s are] monumentally rare, more rare than being bitten by someone from New York, statistically speaking. Whereas humans are — conservatively, this is an underestimate — we’re taking at least 100 million sharks out of the ocean every year.

And what we’re finding as scientists is that [sharks] … reproduce more slowly than we realized, even more slowly than people. And so many, many shark populations are really in trouble. And that’s not good because sharks as predators are really helpful for keeping the rest of the food items, the prey in the food web, in check and keeping them in balance.

The terminology may sound unnatural or silly to some people, but that’s because most people’s concept of what is a shark attack is really based on the rarest kind.– Toby Daly-Engel, marine scientist 

What kind of a difference do you believe this change of terminology could mean for how people view sharks?

I hope that it sheds light on the fact that sharks have more to fear from us than we do from them.

Like I said, the terminology may sound unnatural or silly to some people, but that’s because most people’s concept of what is a shark attack is really based on the rarest kind. 

Sharks are much more careful, much more fragile than people realize. They’re very long lived. Some species we now know can live over 400 years. They’re more likely to scavenge dead prey than they are to attack live prey, because their natural prey has things like spines and claws and beaks that can hurt them.

So when an attack occurs on a human, it’s because we are in their environment and they mistake us for a natural prey item, or they don’t know what we are and they go to figure it out with. Like dogs and babies, sharks can only really figure things out using their mouths.

A spokesperson for a group representing people who have been bitten by sharks told the [Sydney Morning Herald] that he’s worried about “sanitizing” shark bites. What would you say to him?

I would say that shark attacks in general are going down per capita, even though the number of people that are in the water is going up. And that’s because we know we’ve lost up to 70 per cent of all sharks just in the last 50 years. And that is going to have grave consequences on our ocean health.

Anybody who likes the ocean, likes seeing fish in the ocean, all of that diversity is in danger without the predators. And most sharks are not at the top of the food chain. Most sharks are not what we think of as apex predators. There’s not that many massive ones. Most sharks are these cute little medium-sized things. They are both predator and prey. And without them, what we see is what’s called extinction cascade.

Considering you’re more likely to get struck by lightning … than bitten by a shark, considering you’re more likely to be killed by a vending machine than a shark, I think that there is very little chance of this type of measure minimizing shark attack. It has a much better chance of kind of helping people to understand that most of what the media calls shark attacks are really not the shark’s fault. They’re really just due to people.

Maybe we need some horror movies about vending machine attacks and New York City bite attacks.

I mean, just don’t shake them. Like, if you can’t get your chips out, just leave them there. That’s all I can say.

But after movies like Jaws and the innate fear that people have about sharks, is rebranding really going to make much of a difference here?

Even if there’s some mockery, there’s some silliness, regardless of this kind of attention, if it can help people understand the role that sharks play in the ecosystem and how mistaken our ideas are about shark attack, then, yeah, maybe it’ll do a little bit of good.

Sharks are feared. There are very few laws protecting them. And yet we know that these things grow more slowly and reproduce more slowly than just about any animal on Earth. And so they are incredibly in need of protection.

So every little bit can help because there’s not a lot of, you know, big movements out there for shark advocacy. There’s no such thing as shark-safe tuna, for instance. So I think because there is that fear, it’s even more important that institutions speak up on behalf of these animals, which are really, really important to the health of our planet’s oceans.

NASA hears from Voyager 1, the most distant spacecraft from Earth, after months of quiet

Published

 on

 

CAPE CANAVERAL, Fla. (AP) – NASA has finally heard back from Voyager 1 again in a way that makes sense.

The most distant spacecraft from Earth stopped sending back understandable data last November. Flight controllers traced the blank communication to a bad computer chip and rearranged the spacecraft’s coding to work around the trouble.

NASA’s Jet Propulsion Laboratory in Southern California declared success after receiving good engineering updates late last week. The team is still working to restore transmission of the science data.

It takes 22 1/2 hours to send a signal to Voyager 1, more than 15 billion miles (24 billion kilometers) away in interstellar space. The signal travel time is double that for a round trip.

Contact was never lost, rather it was like making a phone call where you can’t hear the person on the other end, a JPL spokeswoman said Tuesday.

Launched in 1977 to study Jupiter and Saturn, Voyager 1 has been exploring interstellar space – the space between star systems – since 2012. Its twin, Voyager 2, is 12.6 billion miles (20 billion kilometers) away and still working fine.

SpaceX launches 23 Starlink satellites from Florida (photos)

Published

SpaceX sent yet another batch of its Starlink internet satellites skyward today (April 23).

A Falcon 9 rocket topped with 23 Starlink spacecraft lifted off from Florida’s Cape Canaveral Space Force Station today at 6:17 p.m. EDT (2217 GMT).

The Falcon 9’s first stage came back to Earth for a vertical landing about 8.5 minutes after launch as planned. It touched down on the SpaceX droneship Just Read the Instructions, which was stationed in the Atlantic Ocean.

It was the ninth launch and landing for this particular booster, according to a SpaceX mission description. Five of its previous eight liftoffs were Starlink missions.

The Falcon 9’s upper stage will continue carrying the 23 Starlink satellites toward low Earth orbit (LEO) today, deploying them about 65 minutes after liftoff.

This evening’s launch was the 41st of the year for SpaceX, and the 28th of 2024 dedicated to building out the huge and ever-growing Starlink megaconstellation. There are nearly 5,800 operational Starlink satellites in LEO at the moment, according to astrophysicist and satellite tracker Jonathan McDowell.

The Starlink launch ended up being the first half of a spaceflight doubleheader: A Rocket Lab Electron vehicle launched two satellites, including a NASA solar-sailing technology demonstrator, from New Zealand today at 6:33 p.m. EDT (2233 GMT).

Editor’s note: This story was updated at 6:30 p.m. ET on April 23 with news of successful launch and first-stage landing.

Getting to know Samantha Letourneau

By day, Samantha Letourneau is Vancouver Island University’s Canada Learning Bond project lead and Volunteer Tutor Coordinator. She’s also a musician and dancer and for the past two years, she’s been collaborating with Swedish artist Mårten Spångberg, thanks to funding obtained through Crimson Coast Dance, to create a digital art installation that goes live on Friday, April 26. A launch event takes place at Black Rabbit restaurant in the Old City Quarter that night. Samantha is also hosting a creative process workshop on April 27 and 28.

Can you share a bit about your background as an artist and how you got into it?

I have been working in art for a very long time, as a musician and dancer as well as an art administrator and program coordinator. I started music at the age of 11 and dance came later in my life in my early 20s. I always wanted to do dance, but I grew up in a small community in Yellowknife and at that time the only dance classes available were highland dancing, which I was not very interested in. 

In my early 20s while living in Vancouver, I took classes in contemporary dance and was fortunate to land a small part in the Karen Jameison Dance company for a piece called The River. The River was about rivers and connection between the reality of a real and physical outdoor river and the different reality of “the river within.” It was both a piece of art and outreach for the community. It included working with the S’pak’wus Slu’lum Dancers of the Squamish Nation. Somewhat ground-breaking for 1998.

From there I was hooked and wanted to do more in dance. I studied a lot and took many classes. Fast forward to now, I have been involved with productions and performances with Crimson Coast Dance for more than 15 years and greatly appreciate the talent and innovation that Artistic Director Holly Bright has brought to this community. She is amazing and very supportive of artists in Nanaimo.

How did this international exchange come about?

The Nordic/Nanaimo exchange is one of the innovative projects Holly created. At the height of the pandemic, funded by BC Arts Council and Made In BC, Crimson Coast Dance embarked on a project that explored the ways in which Nanaimo artists could participate in online exchanges. 

Two artists in Nanaimo – myself and Genevieve Johnson – were introduced to artists from Europe and supported through this international exchange. My collaborator, Mårten Spångberg, is a Swedish artist living and working in Berlin. An extension of that exchange is funded by Canada Council for the Arts – Digital Now.

What brought Mårten and myself together – and I quote Mårten here – is “questions around climate change, ecology and the influence contemporary society has on its environments. We are not interested in making art about the ecological crises or informing our audience about the urgency that climate change implies, but instead through our research develop work that in itself proposes, practices and engages in alternative ecologies.”

We share an understanding that art is a unique place, in the sense of practice, activation, performance and event, through which alternative ecologies can emerge and be probed and analyzed.

Tell us about the launch event.

We are launching the digital art installation that Mårten and I created on April 26 at The Attic at Black Rabbit Restaurant. The event is free to attend but people must sign up as seating is limited. I produced video art with soundscapes that I recorded mixing field recordings with voice and instrumentation. Marten explores text, imagery and AI.

My focus is on the evolving and ongoing process of how we communicate with each other and to nature within a digital context.

During our collaboration, Mårten and I talked about networks, though not just the expansive digital network of the internet but of nature. We shared thoughts on mycelium, a network of fungal threads or hyphae, that lately has received much attention on the importance of its function for the environment, including human beings.

Building off this concept, ideas of digital and ecological landscapes being connected emerged. From this we worked both collaboratively and individually to produce material for this digital project. Mårten will be there via Zoom as well and we will talk about this two-year process and the work we created together.
