1 . European shepherds (牧羊人) and ranchers (大牧场主) are taking the lead in forest fire prevention, by leading their animals to clear away underbrush that allows fires to grow too big, a new study shows.
In thinner forested areas, large herbivores (食草动物) were found in a study to be greatly effective in reducing forest fire risk. “In general terms, it is clear that wild and semi-wild herbivores like horses can reduce wildfire risk through their eating grass,” says Julia Rouet-Leduc, lead author of the study. “Such herbivores can be particularly effective in remote areas, where careful management can prevent wildfire and benefit wild nature in other ways.”
Smaller animals like goats and sheep are ideal for areas that lack natural predators (捕食者). There are no large predators in all of Italy, and without the risk of losing an expensive animal, the eating habits of these smaller animals kept on a farm make them perfect for clearing underbrush and things which larger herbivores can’t stomach.
But there were laws that prevent goats and sheep from entering woods in order to protect them. Since natural numbers of red deer, and other native herbivores have long since disappeared from European forests, the loss of sheep and goats meant that nothing prevented grass from spreading in forests, turning brushfires into dangerous disasters.
That’s why shepherds on Sardinia have written a letter to the Italian Ministry of Agriculture, asking not only to allow their animals to eat grass within the woods, but to create a restoration project of rural areas in Montiferru, where Italy’s worst wildfire in 40 years recently burned its way from the mountain tops to the sea.
Their plan is to bring in more shepherds to better control the fires, and encourage eco-tourism in the area, to incentivize the shepherds to stay. This is already seeing success through both private and public inspiring measures in Catalunya, Spain.

5 . Joshua trees — some of the most unusual and famous plants of the American Southwest — have survived as a species for some 2.5 million years in the Mojave Desert. Now, they may face extinction due to climate change.
In a new study published in the journal Ecosphere, researchers and volunteer scientists surveyed nearly 4,000 trees in southern California’s Joshua Tree National Park to figure out where the oldest trees grew the best during historic periods of extreme heat and drought. Then, the researchers estimated (估算) how many of these Joshua safe areas would survive to the end of the century based on a range of climate change predictions.
The study authors found that if greenhouse gas emissions (排放物) are seriously limited and summer temperatures are limited to an increase of 5.4 degrees Fahrenheit, about 19% of the park’s Joshua tree habitat (栖息地) would survive after the year 2070. If no action is taken to reduce greenhouse gas emissions and summer temperatures rise by 9 degrees Fahrenheit or more, however, only 0.02% of the tree’s habitat would survive to the end of the century, leaving the tree close to extinction.
One way to save the Joshua trees from extinction is to reduce greenhouse gas emissions. However, even if the habitats survive, these trees will still be in danger because of wildfires, which have also been happening more often as the climate warms. According to the researchers, fewer than 10% of Joshua trees survive when wildfires rush through their habitats.
“Removing grass is a way park rangers (护林员) are helping to protect the area from fire today,” Sweet, a plant ecologist at the University of California, said. “By protecting the trees, they’re protecting a host of other native insects and animals that depend on them as well.”

6 . A couple, Jake Williams and Charlotte Sinclair, were absolutely done with the long isolation (隔离), following a few years of COVID-19, and then they decided to launch (发起) a community plan. They started Talk the Walk and managed to make people get together, explore London on foot, and get to know each other.
The number one mission was to have fun — even if only a few people showed up for the free events. That’s what they expected when they started on Meetup.com. Suddenly they were getting hundreds of people responding with excitement.
200-300 people of various ages now regularly attend each event, which opens with the playing of icebreaker games. The couple designed the games to be easy for shy people, too, with “fun questions” breaking the nervousness. They picked interesting places to visit. Attendees were even surprised with an offer of chocolate.
“I’ve done some crazy things in my time working from home to stop loneliness, like dog sitting for people and joining gyms just so I can have more conversations with people,” Jake said.
“I think that it’s hugely impactful for people who have been affected by COVID-19, by being forced to work from home and having that isolation,” he continued.
They’ve seen older people talking with younger people, and people becoming friends — so much so that the strangers are now meeting on their own after becoming familiar.
Talk the Walk organised their last event last year, but said they’ll be back once it starts to warm up again.
Nearly 2,000 members in their Meetup community and followers on their Facebook Page are waiting for that day, but at the same time, this young couple might serve as your very own inspiration to connect people in your own communities.
