1 . In the struggle to survive the ever hotter deserts of California, there are winners and losers. Among the losers are desert birds, whose populations have fallen among the heat stress of climate change. The winners, it turns out, are small burrowing mammals（穴居哺乳动物）, which take refuge from the sun underground. Researchers noted that the stable mammals populations formed a striking contrast to the extremely bad condition of birds.

But why? Birds had a higher evaporative（蒸发）heat loss. Birds were more exposed to the effects of warming, so they had higher energy costs to maintain their body temperature. However, mammals were able to reduce their body temperature by using burrows during the day.

Temperatures have risen about 4 degrees Fahrenheit on average across the area studied, but the heat affects birds and small mammals differently. As part of the study, scientists modeled each species' body temperature and cooling needs under different desert conditions. To calculate that, they measured the conductivity（传导率）of the animals' fur or feathers, and used information on their heat reducing behaviors.

The models showed that in the fight against climate change, there was not a level playing field for furred and feathered desert animals. Cooling costs—or the resources needed to maintain stable body temperature—were about 3. 3 times higher for birds than they were for small mammals, the study reported.

Small mammals have shown this remarkable stability. It's really quite interesting that, in the same region, with the same level of climate change, these two species have responded very differently to the changes taking place. Insights into the status of different species can help scientists take steps to protect them, such as increasing fire prevention in high desert areas, and enhancing water sources in those areas. The study also demonstrates that climate change is already reshaping the California desert

3 . A months-long rescue operation to save giraffes from Longicharo Island’s rising water in Kenya recently concluded after delivering the last two stranded giraffes to safety at the Ruko Community Wildlife Conservancy. Save Giraffes now partnered with Northern Rangelands Trust and local conservation agencies to transfer the Rothschild’s giraffes, one of the most endangered populations of giraffe.

To get the giraffes from the sinking island to the mainland nearly one mile away, community members built a “giraft”, a custom-made ship with tall sides, supported by 60 empty drums. The giraffes were transferred one at a time. “Water levels in Lake Baringo have been rising for some time, but in 2020 the rate of rise increased — flooding lakeshore homes, businesses, and threatening the lives of a small group of Rothschild’s giraffes on Longicharo Island, in Ruko Conservancy,” Northern Rangelands Trust said in a statement.

“At last, they can safely breed (繁殖) and bring back the population of the free-ranging Rothschild’s giraffes to their former home ranges in Baringo. It’s such a relief for all involved to have gotten them safely across to the mainland and we are sure they’re enjoying the space in their new home,” he said.

Rothschild’s giraffes were once widespread across Kenya, Uganda and southern Sudan, but numbers have decreased by 80%, leaving only 3,000 in the wild today. But there is hope, given by innovative (创新的) conservation teamwork such as this.

“Working with the communities in the area over the next several years, we will keep this combined group of giraffes safe, and as they breed, their numbers will grow over time, eventually rejoining their cousins in Uganda,” Save Giraffes Now said in a statement.

6 . The bee population is dropping sharply. In some areas, losses of honeybees are reported to be as high as 75 percent.     1     Bees are primary pollinators (授粉者) in both the human and animal food chains.

Few of us are research scientists and able to spare some lab time to help bees, but there are some things we can all do to assist bees.

Plant things that bees like. Bees are all about pollen (花粉). If you want to support many different varieties of bees, plant some things which will feed them. The good news here is that bee-friendly plants are easy to grow.     2     Try cherry trees, orange trees and other flowering trees.

    3     Unlike honeybees, which live in man- made bee boxes, natural bees make use of many kinds of shelter; dead trees, branches and underground nest tunnels. You can help wood-nesting bees by setting out a few inexpensive bee blocks.

Avoid using garden pesticides (杀虫剂). Pesticides are bad for bees.     4     You’ll find plenty of tips at OrganicGardenPests. com.

Support your local beekeepers. Beekeeping as a hobby has reduced in recent years. Lack of funding and changes in bee populations have made raising bees less attractive, but we still rely heavily on honeybees to pollinate our crops and gardens.     5     There are health benefits to eating local honey, and keeping small beekeepers in business is good for everyone.

8 . It was our first evening dog-sitting while our teenage daughter Rochelle was on vacation for two weeks. Louie searched the entire house for his “mommy”. Then, that disappointed but determined puppy （小狗） developed a plan.

While my husband Paul and I were watching TV, we heard loud noises. Something heavy was being dragged down the stairs. I looked around and saw this six-month-old puppy laboriously dragging his large, hard-sided carrier down the stairs. The next moment saw him drag his possessions one by one, first his blanket, and then his bowl, bone, ball and sweater. The project took most of the evening but Louie showed no sign of tiredness at all.

After packing all the items into the carrier, he attempted to jump inside. Once inside, he got the zipper between his teeth and, with all the strength, he pulled the zipper closed. Then he lay down and went to sleep in it throughout the night. The message was abundantly clear. He wanted to go see his “mommy”. He had seen her pack her suitcase and go away for her vacation. He must do the same so he could find her. When I unzipped his carrier in the morning, Louie was excited, but his “mommy” was nowhere to be seen.

The puppy surprised us with new undertakings every day. His absolutely favorite activity was going for a car ride. The possibility of stopping at McDonald's was his consideration. But one day, my husband didn't stop at McDonald's. He left Louie in the car with the window slightly open while he went to a drugstore. Louie managed to jump out of the window. He walked two blocks and found Paul, walking around him as if saying, “Can we go to have fried chicken now?”

Louie is an old gray-haired dog now, but he is still up to his old, and new, tricks.

10 . While visiting Lake Louise last summer, one of the most famous sights in the Canadian Rockies, I saw a plastic spoon float by in the green water. Whether someone had thrown the spoon into the water, or if it was blown in by the wind, the sight surprised me. It was a sad reminder (提醒物) of the reach that plastic pollution has. Try as I might, I could not reach that spoon, and had to watch it float away.

Grist wrote about the problem of plastic cutlery (餐具) in an article called “It’s time to take America’s plastic fork problem seriously”: “It’s hard to say how many forks, spoons, and knives Americans throw away, but in 2015 we placed nearly 2 billion delivery (递送) orders. If at least half those meals included single-use cutlery, that would mean we’re throwing away billions of cutlery each year. They don’t just disappear. A recent study of the San Francisco Bay Area found that food and drink packaging made up 67 percent of all litter on the streets.”

Fiona Nicholls, ocean plastics campaigner for Greenpeace UK, said: “We can’t carry on using up land or cutting down forests to make cutlery, cups or packaging that get used for a matter of moments, and could pollute our planet for hundreds of years to come. It’s grotesque.”

As members of the community, we should do our part to stop single-use cutlery. One way is to throw a travel set of reusable cutlery into your bag. Even if you don’t have your own set or forget to bring it with you, there are other ways. When eating out, choose places that offer reusable cutlery. Finger foods like pizza, tacos or sandwiches are also nice choices. If you’re ordering food for delivery, you can also say “no thanks” to plastic forks, knives and spoons.
