Chester Zoo
Cheshire, England

The most visited zoo in the United Kingdom, Chester Zoo asks a team of experts (专家) who do research on six key areas around the world to develop programs that hope to prevent animals from dying out. The zoo runs a number of activities, such as Sing for Songbirds, a partnership with singer/songwriter Ashley Fayth, which tries to make people notice the danger facing songbirds in Indonesia. chesterzoo.org

Wellington Zoo
Wellington, New Zealand

Wellington Zoo is green in more ways than one. The zoo works very hard to reduce (减少) waste and reuse rain water. The zoo supports conservation (保护) programs, and its animal hospital, The Nest TeKōhanga, has treated over 3,400 wildlife patients since its opening in2009. wellingtonzoo.com

San Diego Zoo
San Diego, USA

Over 3,500 endangered animals call San Diego Zoo home, but the biggest achievement of this zoo is the number of endangered animals that are sent back into the wild. The zoo's breeding (饲养) programs provide valuable information on the behavior and health of endangered species in over 45 countries. San Diego Zoo Institute for Conservation Research also asks over 200 conservation scientists to protect some animals from dying out. zoo.sandiegozoo.org

2 . Cat lovers finally have the chance to understand what their pets are saying thanks to a smart collar that can interpret meows and translate them into human speech. Named Catterbox, the collar supposedly has a digital sensor that detects meows, and uses a special program to interpret the meaning behind them.

Developed by London ad agency adam&eveDDB, for Temptations cat treats, the invention comes preloaded（预装）with a dictionary of cat meows and several other sounds to make the interpretation as accurate as possible. “We're fascinated by cats, so we set out on a mission to get to know them better.” said Pete Simmons, global brand director of Temptations.

The promotion video of the smart collar claims that Catterbox, the world's first talking cat collar, is designed to finally help humans understand the meaning of meows. “Cats are often thought of as independent pets quite hard to get to know, so we set up The Temptations Lab to find creative ways to inject even more pleasure into a cat and owner's relationship,” said Richard Brim, executive creative director of adam&eveDDB.

“Studies show cats only meow in order to communicate with humans,” the video adds. “So we set out on a mission to get to know them better. By analyzing different cat meows, we've designed a digital sensor that detects a cat's meow and uses a unique program to turn it into a human voice.” So by using the collar, owners can speak to their cats and expect a meaningful response. The responses are delivered in a British accent, in a voice of the owner's choice, selected through a smartphone app paired with the collar.

A few sample responses are shown on the company's YouTube channel-they are quite funny, but obviously not very convincing. In all probability, Catterbox is useless though it has a very clever marketing means.

4 . The idea of billions of people going through a few masks a week during this pandemic definitely rings alarm bells, but a team of researchers in Melbourne may have the solution.

They’ve discovered that adding millions of discarded face masks to road-paving (铺路) mixtures would actually lower the cost of the road, while preventing billions of them from landfills. Just one kilometer of road would need three million masks, and the polypropylene (聚丙烯) plastic used to make single-use surgical face masks also increased the flexibility and durability of the road.

The new material is a mixture of about 2% torn masks, with recycled concrete aggregate (RCA)—a material obtained from waste concrete and other minerals from destroyed buildings. This recycled material was found in the study to be ideal for two of the four layers generally required to create roadways. Paving a kilometer of two-way road with the RCA and three million face masks would result in a change of 93 tons of waste from landfills.

The final product then is more resistant to wear than asphalt (沥青), as well as being cheaper too, provided there was a method for collecting masks. The research team did a cost-analysis and found that, at $26 per ton, the RCA was about half the cost of mining raw materials, and as much as a third of the cost of shipping the used masks to a landfill.

The widespread application would be ideal for large infrastructure (基础设施) projects. For example, Washington has the 11th worst roads in terms of unaddressed repairs in the U.S. If the damaged roads in Washington state were repaired with the RCA/mask mixture, it would reuse nearly 10 billion masks, sparing American landfills hundreds of millions of tons of trash.

It’s said that the team is looking for private industry partners or governments willing to give their plastic mask road an opportunity for a large-scale test.

5 . Open an app at your smart phone and scan the code bar on the garbage can. When you throw garbage into the garbage can, it will show the weight of the garbage and the points you can get from doing so.     1     It will become more popular in the future. Yes, we are talking about the smart garbage can.

    2     The environmental problems have become constant headaches in the development of those cities. Encouraging garbage classification has become an effective way.

In some cities, a variety of multifunctional smart garbage cans are being put into use. In Beijing, for example, a smart garbage can is equipped with an LED screen, which not only shows national policies on garbage classification but also shows the correct steps for garbage sorting. It can also calculate the weight of the garbage and the accumulated points one can get. They can be traded for some articles of daily use.     3     Its body is actually a screen. It is equipped with some Internal sensors. When people throw garbage into it, the internal sensors can automatically tell the types of the garbage. Meanwhile, people can see how to deal with them.     4    

Garbage disposal is a small issue that involves everybody each day. However, it is also a big issue.    5     With smart garbage cans in our daily life, the idea of garbage sorting will become more established. Our dream of building a greener and more beautiful China will come true so long as we start to make small changes right now.
