1 . Generally speaking, convenience and safety affect how we choose to pay for things. Environmental concerns do, too.
Each time you pull out a credit, use a phone’s wallet app or hand over cash, you take part in a system. Some parts of that system make things, like coins, bills or cards. Other parts move money between buyers, sellers, banks and others. Used cash, cards and equipment will be eventually disposed of (处理), as well. Each part of this system uses materials and energy. And all parts produce waste.
Now researchers are looking more closely at how “green” these payment systems are. They’re finding buyers can help cut some of the environmental costs, no matter how they pay.
To understand the full “cost” to society of money or any other system, researchers can perform what’s called a life-cycle assessment. It looks at all the environmental impacts of a product or process. It starts with mining, growing or making the raw materials. It includes what happens while something is in use. And it considers the final disposal or reuse of things.
Even though raw materials are the first step, in fact there are raw materials added in at every single step along the journey. For money, raw materials go into each step of something that is “made”. Fuels are the raw materials for energy to make products and transport them. More energy goes into using products. Recycling or disposal also requires energy, plus water, soil or other materials.
People don’t realize most of those steps, so they can’t judge if one form of payment is dirtier or more costly. And that’s a problem, researchers say. It’s also what has got some of them to show more about the costs of how we pay for our lifestyles.
A life-cycle assessment doesn’t tell you what to do. However, it gives you an informed basis for making a decision.

2 . Time is running out for coral reefs as the climate gets hotter. So scientists are searching the globe for corals that are better at enduring heat, Now, new research shows how those “super corals” can survive: less roommate drama.
Reefs depend on a crucial partnership between the corals and the algae (海藻) that live in the corals’ tissue, The algae make food for the corals using sunlight and in exchange, get a nice spot to live. But when oceans heat up, that relationship goes bad, and the corals kick the algae out, Without their roommates, corals can die, turning a ghostly white, bleached (白化) color.
Still, some corals seem to resist bleaching better than others, A new study shows that those corals depend on algae that are better at tolerating heat. Researchers hope that pinpointing these abilities will help develop new conservation tools to preserve the world’s reefs as temperatures rise. About 1/4 of all marine life rely on coral reefs in some way, along with half 1 billion people around the world also depend on reefs for their food and livelihoods.
“Heat stress can kill a lot of corals really fast,” says Kate Quigley, a research scientist at James Cook University and the Minderoo Foundation in Australia. “I hope that nature does have some mechanisms to get us through the next few years while we get our act together.”
While the hope is that those algae could also aid in reef conservation in the future, researcher Patrick Buerger says it’s likely that it wouldn’t help all coral species. And even the toughest corals can only endure so much. Currently, the world is on track for just under 3degrees Celsius of warming by 2100, a level that would wipe out nearly all coral reefs.
“The action has to be on climate change,” he says. “This is a short-term solution that might buy some time for corals to adapt. But the main focus has to be on climate. There’s not a silver bullet to the problem.”

4 . In order to learn about advanced scientific technology and ideas for combating desertification, Rezaali Pakzad left the Iranian capital Teheran, in 2018, to study in Northwest China’s Gansu Province.
He is a 27-year-old doctoral student at Lanzhou University, focusing on soil desertification control. In his view, Iran, like other arid and semiarid countries, faces environmental problems such as desertification. When he did field surveys and research in Minqin county, Gansu, he found that the local desertification characteristics were very similar to those of his hometown.
“Minqin is between two deserts. From being “about to disappear” to being gradually green, from being ravaged by “sand devils” to being covered by vast green plants, the scientific and effective prevention and control methods of the Chinese government have greatly changed the county, and made me see the hope of improving the ecology in my hometown,” he says.
He believes that China has certainly contributed to the global effort to combat desertification, and that the Chinese contribution is worth learning from. China has developed advanced technology models, such as quicksand fixation and vegetation restoration, and protective forest systems along major transport routes, which have introduced more green to deserts.
Already among the top nations in the world in the field of combating desertification, China has shared its experience with other countries, carried out international exchanges and cooperation, and contributed to global desertification control, he says.
He believes he has made progress during his five years of living and studying in China. By learning more about the Chinese language and culture, he has adapted to life in China and enjoyed the help and sincere concern of his teachers, classmates and friends here.
He hopes to achieve a lot, at a high level, in his research field and to contribute to international exchanges and cooperation in desertification control. “I want to be an ‘ecological messenger’ by spreading green ideas,” he says.

9 . A rare wild flower is being re-established in Devon fields thanks to some four-legged helpers. A conservation charity called Planflife has employed donkeys as “ecosystem engineers”to encourage the return of the endangered small-flowered catchfly.
The catchfly was once found all across Britain but now it only grows in small areas of Wales and the south and west of England. Experts blame its decline on modern farming practices. The flower flourished around the edges of sandy fields where farmers grew their crops, but because of weedkillers that were used to remove “unwanted” plants, and fertilisers to boost crop yields, its habitat has largely disappeared.
Plantlife teamed up with the Donkey Sanctuary, a charity that looks after donkeys in the UK and around the world. It owns several farms across Devon and the UK, where it takes care of hundreds of rescued donkeys, as well as maintaining habitats for other wildlife. More than 20, 000 seeds have been scattered on fields at the sanctuary’s main Devon farm, and it is hoped that many will grow into plants this summer. They will provide food for threatened bird species such as linnets, yellowhammers and skylarks. Plantlife then aims to get the donkeys themselves involved, testing whether catchfly seeds benefit from being trampled into the ground as the donkeys take their exercise. Many plants have seeds that must be pressed into the soil in order to germinate.
“We’re incredibly grateful to partners like the Donkey Sanctuary who are helping these fantastically rare wild flowers come back from the edge of extinction,” Cath Shellswell of Plantlife told The Guardian newspaper. “We look forward to seeing small-flowered catchfly return and we are working with the sanctuary to ensure that this tiny plant has a thriving future. ”

10 . Nuclear pollution has long been a global concern, with major accidents like those at Three Mile Island, Chernobyl, and Fukushima highlighting the serious health and environmental risks associated with nuclear disasters. These incidents not only caused immediate health issues such as radiation sickness and increased cancer rates but also led to long-term environmental damage and genetic mutations in affected populations. Consequently, nuclear pollution remains a significant worry for governments, academics, and society worldwide.
When nuclear accidents occur near coastlines, the marine environment becomes a key point due to the vital role oceans play in climate regulation, food security, and supporting billions of livelihoods globally. In recent years, escalating threats to marine ecosystems from mounting ocean pollution have spurred increased public awareness of marine environmental protection. Studies have shown that human activities pose a significant threat to marine environments, emphasizing the need for improved environmental governance and measures to address environmental risks.
Following the Fukushima nuclear disaster in 2011, efforts to cool the reactors by injecting seawater led to the accumulation of a vast amount of nuclear waste within the Fukushima Nuclear Power Plant’s water storage tower. Despite attempts to manage this waste, the Japanese government’s decision to discharge nearly 1.26 million tons of nuclear wastewater into the Pacific Ocean over the next 40 years has faced opposition from neighboring countries, Japanese residents, and international environmental organizations.
This discharge poses substantial risks to marine life, fisheries, and human health. Radioactive isotopes (放射性同位素) such as tritium, carbon-14, cobalt-60, and strontium-90 present in the wastewater can accumulate in marine organisms, ultimately affecting human populations through the food chain. Therefore, further research and mitigation measures to address the wide-ranging consequences of nuclear pollution on the environment and human health are urgently needed.
In conclusion, while nuclear power may offer benefits, the potential risks, as highlighted by incidents like Fukushima, underscore the importance of stringent safety measures and thorough consideration of environmental impacts.
