What ’30 by 30′ conservation could mean in Canada

Published

 on

OTTAWA —
Prime Minister Justin Trudeau was unequivocal Wednesday when asked if Canada was going to meet its goal to protect one-quarter of all Canadian land and oceans by 2025.

“I am happy to say that we are going to meet our ’25 by 25′ target,” Trudeau said during a small roundtable interview with journalists on the sidelines of the nature talks taking place in Montreal.

That goal, which would already mean protecting 1.2 million more square kilometres of land, is just the interim stop on the way to conserving 30 per cent by 2030 — the marquee target Canada is pushing for during the COP15 biodiversity conference.

But what does the conservation of land or waterways actually mean?

“When we talk about protecting land and water, we’re talking about looking at a whole package of actions across broader landscapes,” said Carole Saint-Laurent, head of forest and lands at the International Union for Conservation of Nature.

The group’s definition of “protected area,” which is used by the UN convention on biodiversity, refers to a “clearly defined geographical space” that is managed by laws or regulations with the goal of the long-term protection of nature.

“It can range from areas with very strict protections to areas that are being protected or conserved,” said Saint-Laurent.

“We have to look at that entire suite of protective and restorative action in order to not only save nature, but to do so in a way that is going to help our societies. There is not one magical formula, and context is everything.”

The organization, which keeps its own global “green list” of conserved areas, lists 17 criteria for how areas can fit the definition.

Most of the criteria are centred on how the sites are managed and protected. One allows for resource extraction, hunting, recreation and tourism as long as these are both compatible with and supportive of the conservation goals outlined for the area.

In many cases, industrial activities and resource extraction are not allowed in protected areas. But that’s not always true in Canada, particularly when it involves the rights of Indigenous Peoples on their traditional territory.

In some provincial parks, mining and logging are allowed. In Ontario’s Algonquin Park, for example, logging is permitted in about two-thirds of the park area.

Canada has nearly 10 million square kilometres of terrestrial land, including inland freshwater lakes and rivers, and about 5.8 million square kilometres of marine territory.

As of December 2021, Canada had conserved 13.5 per cent of land and almost 14 per cent of marine territory. The government did it through a combination of national and provincial parks and reserves, wildlife areas, migratory bird sanctuaries, national marine conservation areas, marine protected areas and what are referred to as “other effective areas-based conservation measures.”

These can include private lands that have a management plan to protect and conserve habitats, or public or private lands where conservation isn’t the primary focus but still ends up happening.

Canadian Forces Base Shilo, in Manitoba, includes about 211 square kilometres of natural habitats maintained under an environmental protection plan run by the Department of National Defence.

The Nature Conservancy of Canada is a non-profit organization that raises funds to buy plots of land from private owners with a view to long-term conservation.

Mike Hendren, its Ontario regional vice-president, said that on such lands, management plans can include everything from nature trails to hunting — but always with conservation as the priority.

To hit “25 by 25,” Canada must further protect more than 1.2 million square kilometres of land, or approximately the size of Manitoba and Saskatchewan added together. To get to 30 per cent is to add, on top of that, land almost equivalent in size to Alberta.

The federal government would need to protect another 638,000 square kilometres of marine territory and coastlines by 2025, or an area almost three times the size of the Gulf of St. Lawrence. By 2030, another area the size of the gulf would need to be added.

Trudeau said that in a country as big and diverse as Canada, hard and fast rules about what can and can’t happen in protected areas don’t make sense.

He said there should be distinctions between areas that can’t have any activity and places where you can mine, log or hunt, as long as it is done with conservation in mind.

“There’s ability to have sort of management plans that are informed by everyone, informed by science, informed by various communities, that say, ‘yes, we’re going to protect this area and that means, no, there’s not going to be unlimited irresponsible mining going to happen,”‘ he said.

“But it doesn’t mean that there aren’t certain projects in certain places that could be the right kind of thing, or the right thing to move forward on.”

The draft text of the biodiversity framework being negotiated at COP15 is not yet clear on what kind of land and marine areas would qualify or what conservation of them would specifically mean.

It currently proposes that a substantial portion of the conserved land would need to be “strictly protected” but some areas could respect the right to economic development.

STD epidemic slows as new syphilis and gonorrhea cases fall in US

Published

 on

 

NEW YORK (AP) — The U.S. syphilis epidemic slowed dramatically last year, gonorrhea cases fell and chlamydia cases remained below prepandemic levels, according to federal data released Tuesday.

The numbers represented some good news about sexually transmitted diseases, which experienced some alarming increases in past years due to declining condom use, inadequate sex education, and reduced testing and treatment when the COVID-19 pandemic hit.

Last year, cases of the most infectious stages of syphilis fell 10% from the year before — the first substantial decline in more than two decades. Gonorrhea cases dropped 7%, marking a second straight year of decline and bringing the number below what it was in 2019.

“I’m encouraged, and it’s been a long time since I felt that way” about the nation’s epidemic of sexually transmitted infections, said the CDC’s Dr. Jonathan Mermin. “Something is working.”

More than 2.4 million cases of syphilis, gonorrhea and chlamydia were diagnosed and reported last year — 1.6 million cases of chlamydia, 600,000 of gonorrhea, and more than 209,000 of syphilis.

Syphilis is a particular concern. For centuries, it was a common but feared infection that could deform the body and end in death. New cases plummeted in the U.S. starting in the 1940s when infection-fighting antibiotics became widely available, and they trended down for a half century after that. By 2002, however, cases began rising again, with men who have sex with other men being disproportionately affected.

The new report found cases of syphilis in their early, most infectious stages dropped 13% among gay and bisexual men. It was the first such drop since the agency began reporting data for that group in the mid-2000s.

However, there was a 12% increase in the rate of cases of unknown- or later-stage syphilis — a reflection of people infected years ago.

Cases of syphilis in newborns, passed on from infected mothers, also rose. There were nearly 4,000 cases, including 279 stillbirths and infant deaths.

“This means pregnant women are not being tested often enough,” said Dr. Jeffrey Klausner, a professor of medicine at the University of Southern California.

What caused some of the STD trends to improve? Several experts say one contributor is the growing use of an antibiotic as a “morning-after pill.” Studies have shown that taking doxycycline within 72 hours of unprotected sex cuts the risk of developing syphilis, gonorrhea and chlamydia.

In June, the CDC started recommending doxycycline as a morning-after pill, specifically for gay and bisexual men and transgender women who recently had an STD diagnosis. But health departments and organizations in some cities had been giving the pills to people for a couple years.

Some experts believe that the 2022 mpox outbreak — which mainly hit gay and bisexual men — may have had a lingering effect on sexual behavior in 2023, or at least on people’s willingness to get tested when strange sores appeared.

Another factor may have been an increase in the number of health workers testing people for infections, doing contact tracing and connecting people to treatment. Congress gave $1.2 billion to expand the workforce over five years, including $600 million to states, cities and territories that get STD prevention funding from CDC.

Last year had the “most activity with that funding throughout the U.S.,” said David Harvey, executive director of the National Coalition of STD Directors.

However, Congress ended the funds early as a part of last year’s debt ceiling deal, cutting off $400 million. Some people already have lost their jobs, said a spokeswoman for Harvey’s organization.

Still, Harvey said he had reasons for optimism, including the growing use of doxycycline and a push for at-home STD test kits.

Also, there are reasons to think the next presidential administration could get behind STD prevention. In 2019, then-President Donald Trump announced a campaign to “eliminate” the U.S. HIV epidemic by 2030. (Federal health officials later clarified that the actual goal was a huge reduction in new infections — fewer than 3,000 a year.)

There were nearly 32,000 new HIV infections in 2022, the CDC estimates. But a boost in public health funding for HIV could also also help bring down other sexually transmitted infections, experts said.

“When the government puts in resources, puts in money, we see declines in STDs,” Klausner said.

World’s largest active volcano Mauna Loa showed telltale warning signs before erupting in 2022

Published

 on

 

WASHINGTON (AP) — Scientists can’t know precisely when a volcano is about to erupt, but they can sometimes pick up telltale signs.

That happened two years ago with the world’s largest active volcano. About two months before Mauna Loa spewed rivers of glowing orange molten lava, geologists detected small earthquakes nearby and other signs, and they warned residents on Hawaii‘s Big Island.

Now a study of the volcano’s lava confirms their timeline for when the molten rock below was on the move.

“Volcanoes are tricky because we don’t get to watch directly what’s happening inside – we have to look for other signs,” said Erik Klemetti Gonzalez, a volcano expert at Denison University, who was not involved in the study.

Upswelling ground and increased earthquake activity near the volcano resulted from magma rising from lower levels of Earth’s crust to fill chambers beneath the volcano, said Kendra Lynn, a research geologist at the Hawaiian Volcano Observatory and co-author of a new study in Nature Communications.

When pressure was high enough, the magma broke through brittle surface rock and became lava – and the eruption began in late November 2022. Later, researchers collected samples of volcanic rock for analysis.

The chemical makeup of certain crystals within the lava indicated that around 70 days before the eruption, large quantities of molten rock had moved from around 1.9 miles (3 kilometers) to 3 miles (5 kilometers) under the summit to a mile (2 kilometers) or less beneath, the study found. This matched the timeline the geologists had observed with other signs.

The last time Mauna Loa erupted was in 1984. Most of the U.S. volcanoes that scientists consider to be active are found in Hawaii, Alaska and the West Coast.

Worldwide, around 585 volcanoes are considered active.

Scientists can’t predict eruptions, but they can make a “forecast,” said Ben Andrews, who heads the global volcano program at the Smithsonian Institution and who was not involved in the study.

Andrews compared volcano forecasts to weather forecasts – informed “probabilities” that an event will occur. And better data about the past behavior of specific volcanos can help researchers finetune forecasts of future activity, experts say.

(asterisk)We can look for similar patterns in the future and expect that there’s a higher probability of conditions for an eruption happening,” said Klemetti Gonzalez.

Waymo’s robotaxis now open to anyone who wants a driverless ride in Los Angeles

Published

 on

 

Waymo on Tuesday opened its robotaxi service to anyone who wants a ride around Los Angeles, marking another milestone in the evolution of self-driving car technology since the company began as a secret project at Google 15 years ago.

The expansion comes eight months after Waymo began offering rides in Los Angeles to a limited group of passengers chosen from a waiting list that had ballooned to more than 300,000 people. Now, anyone with the Waymo One smartphone app will be able to request a ride around an 80-square-mile (129-square-kilometer) territory spanning the second largest U.S. city.

After Waymo received approval from California regulators to charge for rides 15 months ago, the company initially chose to launch its operations in San Francisco before offering a limited service in Los Angeles.

Before deciding to compete against conventional ride-hailing pioneers Uber and Lyft in California, Waymo unleashed its robotaxis in Phoenix in 2020 and has been steadily extending the reach of its service in that Arizona city ever since.

Driverless rides are proving to be more than just a novelty. Waymo says it now transports more than 50,000 weekly passengers in its robotaxis, a volume of business numbers that helped the company recently raise $5.6 billion from its corporate parent Alphabet and a list of other investors that included venture capital firm Andreesen Horowitz and financial management firm T. Rowe Price.

“Our service has matured quickly and our riders are embracing the many benefits of fully autonomous driving,” Waymo co-CEO Tekedra Mawakana said in a blog post.

Despite its inroads, Waymo is still believed to be losing money. Although Alphabet doesn’t disclose Waymo’s financial results, the robotaxi is a major part of an “Other Bets” division that had suffered an operating loss of $3.3 billion through the first nine months of this year, down from a setback of $4.2 billion at the same time last year.

But Waymo has come a long way since Google began working on self-driving cars in 2009 as part of project “Chauffeur.” Since its 2016 spinoff from Google, Waymo has established itself as the clear leader in a robotaxi industry that’s getting more congested.

Electric auto pioneer Tesla is aiming to launch a rival “Cybercab” service by 2026, although its CEO Elon Musk said he hopes the company can get the required regulatory clearances to operate in Texas and California by next year.

Tesla’s projected timeline for competing against Waymo has been met with skepticism because Musk has made unfulfilled promises about the company’s self-driving car technology for nearly a decade.

Meanwhile, Waymo’s robotaxis have driven more than 20 million fully autonomous miles and provided more than 2 million rides to passengers without encountering a serious accident that resulted in its operations being sidelined.

That safety record is a stark contrast to one of its early rivals, Cruise, a robotaxi service owned by General Motors. Cruise’s California license was suspended last year after one of its driverless cars in San Francisco dragged a jaywalking pedestrian who had been struck by a different car driven by a human.

Cruise is now trying to rebound by joining forces with Uber to make some of its services available next year in U.S. cities that still haven’t been announced. But Waymo also has forged a similar alliance with Uber to dispatch its robotaxi in Atlanta and Austin, Texas next year.

Another robotaxi service, Amazon’s Zoox, is hoping to begin offering driverless rides to the general public in Las Vegas at some point next year before also launching in San Francisco.
