Beavers(海狸), like humans, change their surroundings to fit their needs. Known as nature’s engineers, they tear trees down to build homes to live in and dams to raise water levels for protection from enemies. Dams also slow water’s flow while blocking sediment(沉积物)that would otherwise flow downstream. The resulting wetlands often attract wildlife diversity where none had existed. There are challenges, though. Beaver dams sometimes cause flooding, and most people prefer trees alive and upright.

Communities face a delicate balancing act, learning to coexist with beavers. Last winter, many people enjoying Winston Path became beaver fans as one furry family transformed Swallow Pond into an oasis for birds, frogs, turtles and deer.

Yet such activity caused concern. As beavers worked, they raised water levels about five feet. The increased depth allows beavers to survive underwater if the pond ices over. But county officials were concerned about how higher water would affect the soil bank supporting Winston Path.

To find a good balance between protecting the path and the beavers, the county introduced a“ beaver baffle”— a pond leveler.Beavers often rush to fill holes in their dams.Baffles stabilize water levels by creating a hidden exit for high water to escape through the dam, unnoticed by the beavers.

People love the beavers but they also love the mature trees. Recently, Catherine Jones,18, organized a tree-caging event — putting wire cloth around large tree trunks to discourage beavers from biting them. It also protects people from injury due to random trees falling.“We cover the trees we don’t want them to eat, while planting periodically others they like,“said Jones.“We need-to learn to give up a little of our wants to share the Earth’s resources.”

Swallow Pond’s 2023 project will restore proper water depth and improve wildlife habitat without creating problems for the path. The balancing act continues.

For eight years, Handshouse Studio has worked to create toys for Emily and Ruth, two Asian elephants at the Buttonwood Park Zoo in New Bedford.

The founders of the organization, Rick and Laura Brown, are both art teachers and created the “Toys for Elephants” program to challenge their students to make toys for Emily and Ruth and raise the quality of their lives at the zoo. Emily and Ruth were saved from a failed circus (马戏团) in Asia and were badly treated in their youth.

In the spring, the art students make the toys out of wood and other materials (材料). At the end of the semester, the class sends them to Emily and Ruth at the zoo.

This year, the Norwell Fire Department gave away old fire hoses (消防水龙带) to the class. “It’s interesting what use people find in old hoses,” Fire Chief Andrew Reardon said. “To create toys for elephants was certainly a first.” Reardon said they were happy to give Handshouse the old hose to make toys for the elephants and that it was a special chance to be a part of that. “It’s not every day you get to help make toys for elephants,” Reardon said.

Once at the zoo, the students set up their toys around the empty elephant house and quickly leave so Emily and Ruth may come in to play with their new toys. “The students have really embraced this and they really want to have a part to play in solving the serious problem of keeping animals in captivity (圈养),” Rick said.

Handshouse Studio decided to work with other zoos and art and design organizations around the world with the “Toys for Elephants” program. Already, they have been getting calls from all over the world, including New Zealand, Germany and Thailand.

Every day as the sun rises, Ma Hongyi, a 66-year-old farmer, can be seen patrolling (巡逻) Yuncheng Salt Lake with his dog in Yuncheng city, North China’s Shanxi province.

Ma still remembers the day when he first saw two big pink birds wandering through the water. “I had never seen such pretty birds. They were even taller than me, with long wings,” Ma recalls. He was later informed that those birds were flamingos, a rare sight in China, which were listed on the International Union for Protection of Nature’s red list of endangered species in 2013. From that day on, Ma started his second career as a volunteer to prevent human beings from doing harm to the wildlife. “The birds are attracted by the good environment,” Ma says. “I will do my best to protect the lake so that birds can come here every year.”

Yuncheng Salt Lake covers an area of 132 square kilometers and used to serve as a salt production base. As the country began attaching greater importance to environmental protection, an ecological (生态的) protection and development center was set up in 2012 to carry out regular ecological protection and restoration of the lake. “The greatest value of the Salt Lake lies in its ecology, which should be properly protected,” says Chu Xianghao, head of the city. The lake area hosts 292 types of wild animals, along with 782 plant varieties, some of which are newly recorded species in the country.

After patrolling the lake as a volunteer for over four years, Ma was employed by the local government to help with wildlife protection in 2019. “The lake’s ecology is getting better,” Ma says, adding that he looks forward to the arrival of the flamingos every year. “Some of them are my old friends,” he says.
