2 . Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.

Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses （球场） in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.

There are many environment-friendly sports. Power walking is one of them that you could take up today. You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.

Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it’s free.

3 . Fashion designers are always looking for new materials to work with. Lately, it’s all about environment-friendly materials -- recycled tires, mushrooms, even pineapple fibers! What if you want such a pair of shoes? Thaely is here to help.

This sneaker brand out of Dubai wants to fight the growing problem of plastic pollution. Led by 23-year-old Indian businessman Ashay Bhave, they may have found a winning approach: making shoes out of plastic grocery bags. “Thaely” means “plastic bag” in the Hindi language.

“I was looking to create footwear that is cost-effective and safe for the environment,” Bhave said in an interview with a newspaper. “I needed to come up with something that uses recycled plastic without creating any more plastic waste. ”Plastic bags were the perfect solution. He said five trillion plastic bags are used around the world each year. “I was motivated to find a solution to this problem,” Bhave said.

That solution was the fiber called ThaelyTex. Made entirely from plastic bags, the material looks and feels like leather. That sounds promising. Better yet, the production process requires no additional chemicals and produces no poisonous by-products. The result is a smart-looking pair of white low-top sneakers.

Bhave wouldn’t expose the full process for making ThaelyTex, but he said that each pair of shoes was made from up to 15 plastic bags and 22 plastic bottles. Where do they get the materials? Bhave told Elle that was the hardest part. “The biggest challenge we faced was right at the first step of acquiring the plastic bags. ”

Finally, they got help from TrioTap Technologies, a waste management plant. Bhave said they offered to collect the bags and also process them into ThaelyTex.

So far, it seems like things are falling into place. There are already hundreds of pre-orders in place. It sounds like they have some plans for the future. “We have a few more colors coming up,” said Bhave. They also plan to put out a high-top model and bring in a line of clothing. Let’s hope their growth is also friendly to the environment.

6 . Clothes were once used until they fell apart. Not today. In high-income countries in particular, clothing and footwear are increasingly frequently bought, thrown away and replaced with new fashions, which are themselves soon thrown away and replaced.

The so-called ‘Fast fashion’ is having a surprising environmental impact. The first one is water. The fashion industry consumes anywhere from 20 trillion (万亿) to 200 trillion litres every year. Then there are micro-plastics. Plastic fibres are released when we wash polyester (聚酯纤维) textiles, which make up between20% and 35% of the micro-plastics choking the oceans. Added to this are specific chemicals, such as those used to make fabrics stain resistant and the pesticides required to protect crops such as cotton.

Change is badly needed, but will require the fashion industry to work harder to embrace more of what is known as the circular economy. That will involve at least two things: refocusing on making things that last, and so encouraging reuse; and more rapidly expanding the technologies for sustainable manufacturing processes, especially recycling. There’s a big role for research-both academic and industrial-in achieving these and other ambitions.

Researchers could begin by helping to provide more accurate estimates of water use. There is also work to be done on improving and expanding textiles recycling. Undoubtedly, used textiles go to landfill in part because there are relatively few systems that collect, recycle and reuse materials. Such recycling requires the manual separation of fibres, as well as buttons and zips. Different fibres are not easy to identify by eye, and overall such manual processes are time-consuming. Machinery that can help is being developed. Technologies also exist to recycle used fibres chemically and to create high-quality fibres that can be reused in clothing. But these are nowhere near the scale needed.

Another challenge for researchers is to workout how to get consumers and manufacturers to change their behaviour. Other research questions include finding ways to encourage people to purchase long lasting goods; exploring how to satisfy desires for something new while reducing environmental impact; and understanding why certain measures can be successfully scaled up whereas others fail.

8 . Prince William, second in line to the British throne, gave his first TED Talk on Saturday to launch his Earthshot Prize, a competition that will award five £ 1 million prize money every year for the next decade to those who can come up with solutions to environmental problems.

Any person, group or organization around the world is qualified, and any suggestion is welcome, so long as it is applicable globally. It could be a new technology, a new approach, a new governmental policy or any other ideas toward five environmental goals -fixing the climate, purifying the air, protecting nature, cleaning oceans and handling waste.

"Earthshot" was inspired by John F. Kennedy's "Moonshot," an ambitious 1961 mission to get a man on the moon within a decade. The purpose of the prize is partly to arouse excitement and offer what Prince William called “a bit of catalyst, a bit of hope, a bit of positivity" at a time when the world needs. The money will come from donors around the world. The prize committee includes many celebrities.

Prince William has environmental activism in his blue blood. Both his grandfather, and his father Prince Charles were active environmentalists. Prince William acknowledged his heritage by saying he had always listened, learned and believed what they were saying about the environment. Besides speaking wise words, he also puts forward a good prize. Over a million pounds is significantly more than a Nobel Prize and should inspire some serious and creative thinking about the difficulties of Planet Earth. Unlike the Nobel Prize money, the Earthshot money is supposed to be spent on the winning project. ^“If we achieve these goals, by 2030 our lives won't be worse, and we won't have to sacrifice everything we enjoy. Instead, the way we live will be healthier, cleaner, smarter, and better for all of us," he said.

9 . Notpla, a London-based firm, makes a seaweed-based substitute (代替物) for single use plastic packaging. Although some of Notpla’s products are suitable to be eaten, they are designed to be dissolved (溶解) after usage. Made of seaweed instead of a conventional plastic coating, the company’s packaging is fully biodegradable and ideal for use as packaging for kitchen and bathroom supplies like coffee and toilet paper.

According to the United Nations, 331 million kilograms of plastic garbage is produced annually around the world. About 60% of the estimated 9.15 billion tons of plastic produced since the early 1950s has been taken to landfills.

Plastics harm the water, the air, and our bodies. Many experts agree that single-use plastics are unnecessary and dangerous. Some governments and towns in the United States have taken action. New York has banned most plastic shopping bags, while plastic straws have been banned in Miami Beach. Overseas, India stated in August that it plans to place a wide ban on single-use plastics this upcoming summer, with the European Union already implementing this ban.

Seaweed comes in a variety of species and can be harvested or farmed. Notpla uses plants that have been farmed. Rodrigo Garcia Gonzalez and Pierre Paslie, the inventors of Notpla, initially considered seaweed as a solution to the world’s plastic problem for several reasons. Seaweed is plentiful and grows quickly. Additionally it doesn’t compete with land crops and is highly favored for its ability to remove some waste products like carbon from the atmosphere.

In cooperation with the online food ordering service Just Eat, the startup recently tested its product. Last year, the two companies handed out 30, 000 takeaway boxes at various UK restaurants. Plans are in the works to offer the boxes across Europe in 2022. Notpla’s team intends to replace single use plastic in the supply chain more generally as they scale. The company recognizes the difficulty of such a job, considering the volume of plastics consumed around the world.
