1 . Supermarkets, conservationists and farming groups have shown their concerns about pollution of the Wye, one of the UK’s longest rivers. “The pollution pressures upon the Wye are unacceptable and there was strong enthusiasm for cooperative action to resolve the problem.” said Craig Bennett, head of the Wildlife Trusts.
The pollution referred largely to runoff of the nutrient-rich waste matter produced by the 20 million-plus chickens near the river.
Bennett said: “We discussed how, if the Wye were a school or a hospital, we would be calling for it to be placed into ‘special measures’. We agreed the same level of urgency must be applied.”
Increasing concern led the local government to hold a discussion in May, when they promised to publish a plan for the Wye by the autumn. However, the local government’s push on the river was marred in June when the Department for Environment, Food and Rural Affairs published a Wye video showing sea otters (海獺) rather than the river’s local European otters. The pollution of the Wye was not mentioned at all.
In July Bennett hosted a Wye round table in Powys, Wales, bringing together local groups, the Environment Agency, the chicken produce Avara Foodsr, regional branches of the National Farmers Union and local authorities. They agreed on a plan that included cutting the nutrient pollution “through a reduction in animal numbers” and other measures.
Bennett also wrote to Julie James, the Welsh Climate Change Minister, who said, “I share your concern for the health of the River Wye and other Welsh rivers.”
A supermarket chain said they are committed to protecting the river and engaging with their chicken suppliers to tackle water pollution. They have detailed management plans to make sure their suppliers are farming with care for the environment. A government spokesman said: “We are offering a wide range of support to farmers to speed up their transition to more sustainable practices and help protect this important site.”

2 . Artificial intelligence (AI) is showing promise in earthquake prediction, challenging the long-held belief that it is impossible. Researchers at the University of Texas, Austin, have developed an AI algorithm (算法) that correctly predicted 70% of earthquakes a week in advance during a trial in China and provided accurate strength calculations for the predicted earthquakes.
The research team believes their method succeeded because they stuck with a relatively simple machine learning approach. The AI was provided with a set of statistical features based on the team’s knowledge of earthquake physics, and then instructed to train itself using a five-year database of earthquake recordings. Once trained, the AI provided its prediction by listening for signs of incoming earthquakes within the background rumblings (隆隆声) in the Earth.
This work is clearly a milestone in research for AI-driven earthquake prediction. “You don’t see earthquakes coming,” explains Alexandros Savvaidis, a senior research scientist who leads the Texas Seismological Network Program (TexNet). “It’s a matter of milliseconds, and the only thing you can control is how prepared you are. Even with the 70% accuracy, that’s a huge result and could help minimize economic and human losses and has the potential to remarkably improve earthquake preparation worldwide.”
While it is unknown whether the same approach will work at other locations, the researchers are confident that their AI algorithm could produce more accurate predictions if used in areas with reliable earthquake tracking networks. The next step is to test artificial intelligence in Texas, since UT’s Bureau TexNet has 300 earthquake stations and over six years worth of continuous records, making it an ideal location for these purposes.
Eventually, the authors hope to combine the system with physics-based models. This strategy could prove especially important where data is poor or lacking. “That may be a long way off, but many advances such as this one, taken together, are what moves science forward,” concludes Scott Tinker, the bureau’s director.

7 . The American robin (知更鸟) is the state bird for Connecticut, Michigan and Wisconsin because it is a very common, easily seen and handsome bird with a beautiful song. But it is now facing extinction due to the hidden dangers involved in the use of insecticides, a chemical used for killing insects.
Insecticides is usually sprayed on lawns to kill the grass disease. The chemicals used in the US break down into non-poisonous molecules (分子) far faster than DDT did, but most are still highly poisonous to robins for the time that they work on insects. Adult robins hopping on a freshly-sprayed lawn get their feathers coated, and then if they hatch their eggs or babies, the poison can be taken in, to kill the babies.
Elm trees in the United States, like those in Europe, are being attacked by Dutch elm disease. This disease is spread by the elm bark beetle. American scientists have attacked the disease by attacking the carrier. They have treated the trees with a chemical which kills the beetles. But the substance they use sticks to the leaves of the trees. These leaves are a basic food of a certain type of earthworm (蚯蚓) which is itself not attacked by the insecticide. The worms can store up huge quantities of this poison in their bodies. The robin eats these worms and is thus being poisoned by its normal food. The bird is already in danger of dying out in some areas.
It is sometimes difficult to foresee side effects like these, which is why many people object to the use of chemical sprays. They fear that man may be poisoning himself the same way as he has poisoned the American robin and other higher organisms at the top of the food chains.

9 . California’s Water Resources Control Board recently approved new regulations in a unanimous (一致同意的) vote — toilet or shower wastewater will be recycled and pumped into the public drinking water system.
In 2023, more than 97% of California has been in moderate to severe drought, while water suppliers are struggling to keep up. A 2022 water supply and demand report indicated that around 18% of water suppliers were at risk of facing potential shortages. “The reality is that anyone out there on Mississippi River and on Colorado River, and anyone out there taking drinking water downstream is already drinking ‘toilet to tap’,” said Esquivel, a director of the Board.
Early in the 1990s, the state was struggling to overcome the distaste its residents had toward drinking recycled water. Their efforts fizzled out when the phrase “toilet to tap” caught on and met with fierce resistance. The idea became too unpopular to be implemented. Despite the negative name, the regulations are the key to ensuring the supply of drinking water.
California’s new regulations would let water agencies to treat wastewater, and then put it back into the drinking water system. It has taken officials more than 10 years to develop these regulations, a process that included several studies by independent groups of scientists. To put the scheme into effect and build huge water recycling plants, however, water agencies say they will need to prove to people that recycled water is not only safe to drink but also under monitoring.
The new regulations require the wastewater be treated for all bacteria and viruses. In fact, the treatment is so intense that it removes all of the minerals that make fresh drinking water taste good. That means the minerals need to be added back at the end of the process. “What we have here are standards, science, and importantly monitoring that allow us to have safe pure water, and probably better in many instances,” said Esquivel. He added that it takes time and money to build these treatment centers. So, they will only be available for bigger cities at first.

10 . Extended producer responsibility (EPR) refers to a policy approach where producers are given responsibility for the environmental impacts of their products throughout the product lifecycle. Based on the polluter pays principle, this approach requires producers to finance the costs of recycling or disposing of products that consumers no longer want. It aims to shift the costs associated with the management of dealing with solid waste away from the local government.
The term EPR was first coined in 1990 by a Swedish professor, Thomas Lindhqvist, who introduced the idea of producers being responsible for their products to the Swedish Ministry of the Environment. The first example of EPR came in Germany in 1991, where manufacturers picked up household packaging alongside municipal waste collections. Since 1990, countries around the world have adopted EPR policies around key sectors such as packaging, electronics, batteries, and vehicles.
EPR creates a financial motivation for producers to design products that last longer and can be recycled. This is because EPR places the end-of-life costs on the producer. EPR has historically been successful in the managing of products that pose risks to communities such as batteries, paint and old medicines. EPR has led many producers to redesign these items to reduce their risks. Finally, due to ERP closing the loop (循环) on materials management, this approach uses much less energy than it takes to produce items from the beginning.
However, critics of EPR have issues with producers adding recycling costs to the initial price tag of a product. Another disadvantage is that at the international level, it can negatively affect imports to countries that have strict EPR policies as producers in other countries will not want to be subject to extra fees from these policies. Additionally, it restricts competition at the local level as producers who take on the extra costs to accommodate EPR policies are at a competitive disadvantage to those who are able to bend the rules and get out of paying these costs.
