During the UN meeting in South Korea last week, there were high hopes for a new global agreement to reduce the world’s plastic pollution. However, this never materialized and the World Wide Fund for Nature (WWF) considers the outcome as “deplorable” and “a major failure”.

“The world missed a historic opportunity to stop the growing plastic pollution that threatens animals, ecosystems and human health. WWF considers it a major failure that countries at the UN meeting could not agree on a globally binding plastics agreement”, it writes in a press release.

It points out that a large majority of UN member states wanted to see far-reaching measures “that science has shown can stop plastic pollution” – but that a few countries opposed this and stopped the plans.

– It is regrettable that the negotiations did not result in a binding agreement, which is needed to save our planet from drowning in plastic, said Inger Näslund, senior ocean expert at WWF.

The organization points out that it has been over 1000 days since UN countries agreed to establish a legally binding treaty to stop plastic pollution in oceans and on land, and that 800 million tonnes of plastic have been produced since then alone, with over 30 million tonnes leaking into the oceans, harming animals and poisoning ecosystems.

“No intention of finding a solution”

WWF has previously urged countries to vote instead of settling for a watered-down agreement if a consensus could not be reached, but this was not the case, and major oil producer Saudi Arabia was one of several countries that opposed calls to reduce plastic production.

– For too long, a small minority of states have held the negotiation process hostage. It is abundantly clear that these countries have no intention of finding a meaningful solution to this crisis and yet they continue to prevent the large majority of states who do, said Eirik Lindebjerg of WWF International, who followed the negotiations on the ground in Busan.

– In 2025, we want to see countries come to the negotiating table again, but then ready to take the necessary decisions to end plastic pollution, emphasizes Inger Näslund.

Trillions of pieces of plastic debris

Although it is well documented that large parts of the world’s waterways are currently littered with plastic waste, it is still difficult to get a clear picture of the extent of the problem.

According to National Geographic’s estimate, there are around 5.3 trillion pieces of plastic debris floating in the world’s oceans – and in addition to what is on the surface, around four billion plastic microfibers per square kilometer litter the deep sea, threatening a large number of species.

The big problem with plastic waste is not just that it takes a long time to break down. Instead, once it disappears “in plain sight”, it leaves behind tiny microplastic particles that remain in nature and in the oceans for hundreds of years – and are taken up by the species that live there, including fish species that are then consumed by humans.

Radioactive method ready for use against poaching

Rhinos are being injected with radioactive material.

After an extended testing period, the Rhisotope project in South Africa is now in full operation. The technology, which makes rhino horns both traceable and unattractive to poachers, can now be used on a large scale.

It was in June last year that researchers injected radioactive material into the horns of 20 rhinos in South Africa. The project, called the Rhisotope Project and led by the University of the Witwatersrand (Wits University) in South Africa, began six years ago with the idea of stopping poaching of the endangered rhinos. The concept was that the radioactive material should be detectable at border controls, but also becomes toxic to consume. Furthermore, the radioactive material should be harmless to the rhinos.

Now the project has been thoroughly tested and reached full operational status, writes Wits University in a press release.

— We have demonstrated, beyond scientific doubt, that the process is completely safe for the animal and effective in making the horn detectable through international customs nuclear security systems, says James Larkin, professor at Wits University and scientific director of the Rhisotope Project.

Sold as “medicine”

Rhino poaching is a recurring problem, particularly in South Africa. Last year, 420 rhinos were killed illegally in the country, where the horns often end up on the black market. They are often sold as medicine and can be worth more than gold. The treatment is carried out by sedating the rhino and then drilling a small hole in its horn. Two small isotopes with radioactive material are then inserted.

This means in practice that private and public rhino owners, non-governmental organizations and conservation authorities can contact the Rhisotope Project to treat their rhinos with the radioactive material.

— Our goal is to deploy the Rhisotope technology at scale to help protect one of Africa’s most iconic and threatened species. By doing so, we safeguard not just rhinos but a vital part of our natural heritage, says Jessica Babich, CEO of the Rhisotope Project.

Swedish crayfish threatened with extinction

From 30,000 population to under 600 – the noble crayfish is critically endangered.

Crayfish plague continues to devastate Sweden’s native noble crayfish. In just a few decades, populations have plummeted from around 30,000 to fewer than 600 – and the trend continues downward.

The biggest culprit is illegal releases of non-native signal crayfish, which are themselves heavily fished and can also be affected by the disease.

The signal crayfish, which spreads the disease, has increased dramatically and today exists in between 10,000 and 15,000 populations. In Värmland, a province in western Sweden, illegal releases have been documented in as many as 239 bodies of water between 2000 and 2024.

— Noble crayfish populations in Värmland and Dalsland were 430 in the early 2000s; today only 60 remain, says Lennart Edsman, crayfish expert and researcher at the Freshwater Laboratory at the Swedish University of Agricultural Sciences (SLU), to Swedish news agency TT.

When August and crayfish season arrives, the question arises of which species the environmentally conscious consumer should choose for their crayfish party.

— You should eat noble crayfish if you can afford it. That gives them value that makes them worth protecting. And you should eat signal crayfish too, but absolutely not spread them, Edsman believes.

Imports worth hundreds of millions

Swedes eat far more crayfish than the country can produce. Between 70 and 80 percent of the crayfish on tables are imported. In 2023, imports amounted to a value of €40 million, while Swedish crayfish were sold for €27 million.

Previously, the largest portion of imports came from China, but today Spain, Turkey and also Egypt dominate the Swedish market.

Most Swedish-caught crayfish are signal crayfish, with a large share coming from lakes Vättern and Hjälmaren in central Sweden. Recently, however, many consumers have complained that the crayfish have become smaller.

— This is partly because fishing has been too intensive. There is great demand for crayfish in this country. Sweden is quite extreme when it comes to crayfish consumption, Edsman explains.

The signal crayfish originates from western North America, as does crayfish plague – a parasitic algae fungus. Although the species is more resistant than the noble crayfish, it is not immune to the disease.

How the signal crayfish took over

The signal crayfish originally comes from western North America and was introduced to Sweden in the 1960s as a way to replace the noble crayfish, which had been severely affected by crayfish plague at the time. The idea was to preserve crayfish fishing and its economic benefits, since the signal crayfish is more resistant to the disease than the noble crayfish.

The problem is that the signal crayfish carries the very crayfish plague – a parasitic water mold – that is deadly to the noble crayfish. Although the invasive species itself can be affected, it is significantly more resilient, which means it functions as a disease carrier and accelerates the decline of the noble crayfish.

Since its introduction, the signal crayfish has spread rapidly and is now found in between 10,000 and 15,000 populations across Sweden. Many of these have resulted from illegal releases. The consequence is that the noble crayfish has declined from around 30,000 populations to fewer than 600 throughout the country.

New giant insect discovered in Australia

Acrophylla alta lives in a very limited area of high-altitude rainforest.

Researchers have discovered a new species of stick insect. The insect, which can grow to almost half a meter long, is said to potentially be Australia’s heaviest.

It was at high altitude in the Atherton Tablelands in northern Queensland, Australia, that the stick insect was found. Researchers at James Cook University helped identify the new species, which they call Acrophylla alta. The most remarkable thing about the insect is its length and especially its weight: It can grow 40 centimeters long and weigh about 44 grams, which is slightly less than the weight of a golf ball.

— There are longer stick insects out there [in the region], but they’re fairly light bodied, says Professor Angus Emmott in a press release. From what we know to date, this is Australia’s heaviest insect.

It was through the eggs that researchers were able to identify that it was a new species, since no species of stick insects have identical eggs.

— They’ve all got different surfaces and different textures and pitting, and they can be different shapes, he says.

It is not uncommon for new insect species to be discovered, but the reason this heavy insect has gone unnoticed is likely due to its habitat. These insects live in a limited area of high-altitude rainforest and live high up in the tree canopy. Emmott also believes it is precisely their living environment that has made them so large.

— It’s a cool, wet environment where they live, he says. Their body mass likely helps them survive the colder conditions, and that’s why they’ve developed into this large insect over millions of years.

The forest lives when trees die

Leaving a variety of dead trees in forests is vital for many species' survival.

When old trees die, life begins for many other species, according to a new dissertation. Numerous threatened species need dead wood to survive, along with a varied landscape.

Dead wood, meaning dead trees and branches in nature, is vital for about a quarter of Sweden’s beetle species. Many fungal species also depend on dead wood for survival.

Together with microorganisms and fungi, beetles contribute to the decomposition of tree remains, which provides nutrients to the soil and creates habitats for other insects that, in turn, become food for birds and other animals.

However, many of these fungal and beetle species are threatened today, partly because dead wood has become scarce – especially in managed forests. Paulina Bergmark from the Swedish University of Agricultural Sciences (SLU) has examined in her dissertation whether these species are better preserved in landscapes where nature conservation is combined with forestry, often called eco-parks. The state-owned Swedish forestry company Sveaskog established the first eco-parks about 20 years ago, with the aim of supporting species negatively affected by traditional forestry. Today, there are 37 such forests in total.

In five of these eco-parks, Bergmark studied beetle and fungal species living in high-cut stumps. She then compared the results with four areas in regular production forests.

More red-listed species

The eco-parks contained more diverse tree species and good access to dead wood. The production forests had many beetles, but not to the same extent as the eco-parks.

– Generally, we found both more species and a larger number of red-listed species in the eco-parks compared to the production forests, she says in a press release.

The dissertation also highlighted the importance of tree diversity in forests. Different types of dead trees benefit different species, according to Bergmark.

– In the eco-parks’ varied landscapes, there is a larger proportion of forest where both old and young trees contribute to the creation of new dead wood over time. Increasing variation with both deciduous and coniferous trees in different stages of decomposition can be an effective way to strengthen biodiversity in managed forests, she says.
