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.

4 . Carbon dioxide emissions from transportation are now thought as the top source of green-house gases. One of the most effective ways to reduce your carbon footprint is to reconsider how much, and how often, you travel.

Going car free for a year could save about 2. 6 tons of carbon dioxide, according to a study from the University of British Columbia. How can you stop using a car? Try taking a train, bus or better yet, riding a bike.

But let’s be realistic. You will likely need to use a car this year. So, when you do, here are some tips to make your trip more climate-friendly. Driving efficiently can help to reduce emissions. Go easy on the gas and brakes and drive like you have an egg under your foot. Regularly service your car to keep it more efficient. Keeping your tires pumped correctly can re-duce emissions. Low tire pressure will hurt your fuel economy. Air conditioning and frequent city driving can make emissions go up. So cut down on these as often as possible. Use cruise control (定速巡航) on long drives-in most cases, this can help to save gas. Don’t weigh your car down with extra things that you don’t need on your trip.

Fly often? Taking one fewer long round-trip flight could reduce your personal carbon footprint significantly. If you use public transportation often and fly less, your carbon foot-print might still be relatively sustainable, but if you drive and fly a lot, your emissions will be sigher. If you can’t avoid flying, you can offset them by donating money to sustainable proacts, such as supplying efficient stoves to rural homes, or projects which help farmers deal with crop waste environmentally.

5 . 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 . Eradajere Oleita thinks she may have a partial solution to two of our country’s persistent problems: garbage and poverty. It’s called the Chip Bag Project. The 26-year-old student and environmentalist from Detroit is asking a favor of local snack lovers: Rather than toss your empty chip bags into the trash, donate them so she can turn them into sleeping bags for the homeless.

Chip caters drop off their empty bags from Doritos, Lay’s, and other favorites at two locations in Detroit: a print shop and a clothing store, where Oleita and her volunteer helpers collect them. After they sanitize (消毒) the chip bags in soapy hot water, they slice them open, lay them flat, and iron them together. They use padding and liners from old coats to line the insides.

It takes about four hours to sew a sleeping bag, and each takes around 150 to 300 chip bags, depending on whether they’re single-serve or family size. The result is a sleeping bag that is “waterproof, lightweight, and easy to carry around,” Oleita told the Detroit News. Since its start in 2020, the Chip Bag Project has collected more than 800,000 chip bags and, as of last December, created 110 sleeping bags.

Sure, it would be simpler to raise the money to buy new sleeping bags. But that’s only half the goal for Oleita — whose family moved to the United States from Nigeria a decade ago with the hope of attaining a better life — and her fellow volunteers. “We are devoted to making an impact not only socially, but environmentally,” she said.

And, of course, there’s the symbolism of recycling bags that would otherwise land in the trash and using them to help the homeless. It’s a powerful reminder that environmental injustice and poverty often go hand in hand. As Oleita said, “I think it’s time to show connections between all of these issues.”

9 . 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.
