1 . Live with roommates? Have friends and family around you? Chances are that if you’re looking to live a more sustainable lifestyle, not everyone around you will be ready to jump on that bandwagon.

I experienced this when I started switching to a zero waste lifestyle five years ago, as I was living with my parents, and I continue to experience this with my husband, as he is not completely zero waste like me. I’ve learned a few things along the way though, which I hope you’ll find encouraging if you’re doing your best to figure out how you can make the change in a not-always-supportive household.

Zero waste was a radical lifestyle movement a few years back. I remember showing my parents a video of Bea Johnson, sharing how cool I thought it would be to buy groceries with jars, and have so little trash! A few days later, I came back with my first jars of zero waste groceries, and my dad commented on how silly it was for me to carry jars everywhere. It came off as a bit discouraging.

Yet as the months of reducing waste continued, I did what I could that was within my own reach. I had my own bedroom, so I worked on removing things I didn’t need. Since I had my own toiletries (洗漱用品), I was able to start personalising my routine to be more sustainable. I also offered to cook every so often, so I portioned out a bit of the cupboard for my own zero waste groceries. Perhaps your household won’t entirely make the switch, but you may have some control over your own personal spaces to make the changes you desire.

As you make your lifestyle changes, you may find yourself wanting to speak up for yourself if others comment on what you’re doing, which can turn itself into a whole household debate. If you have individuals who are not on board, your words probably won’t do much and can often leave you feeling more discouraged.

So here is my advice: Lead by action.

What was the attitude of the author’s father toward buying groceries with jars?

What can we infer about the author?

4 . It could be said that the northernmost part of our planet holds the secrets of our past as well as our future.

Through our exploration of the Arctic, scientists have discovered more about the biodiversity (生物多样性) of the area as well as how to preserve Earth’s ecosystems. Yet as one of the most severe but most primitive (原始的) places on Earth, the Arctic has been affected by human activities---research and exploration, booming tourism and above all, global warming---in recent decades.

Jonathan Smith, producer of the BBC documentary Blue Planet II, shared his filming experience in the Arctic. “We were all set and ready to film but we needed two major things---walrus (海象) and ice. I had expected that walrus may be hard to find, but I didn't expect it to be hard to find ice,” he told the BBC. “The crew was all commenting on how surprisingly warm it was.”

They were not mistaken. Scientists have been recording changes in the Arctic. Its sea ice minimum in summer, for example, has reduced by 40 percent in the past 30 years, NASA data showed. These changes have had bad influences on the Arctic and the human, animal and plant life that calls it home.

But the effects of these changes are not limited to the inhabitants of this area alone. In fact, it could be said that the weight of the world relies on this icy region. The Earth’s steady climate depends on the Arctic’s sea ice, which acts as a huge white reflector (反光体) at the top of the planet, bouncing some of the sun’s rays back into space. The more Arctic sea ice melts, the less light is reflected, and the more the dark oceans will absorb the sun’s radiation. The Arctic also helps circulate ocean movement, moving cold and warm water around the globe.

With visible changes in the global climate, the Arctic has given us a wake-up call---what happens “up in the North” doesn’t just stay there. It comes with a high cost to the world at large. It's time for us to pay attention to this chilly region and learn more about what’s happening there, as well as its past and possible future.

5 . Modern agriculture and its ability to feed billions of people may be one of humanity’s greatest achievements. However, it comes with hidden costs. For example, have you ever considered how much water is needed to provide you with a steak or a salad? It may surprise you.

In a recent study published in the journal Nutrients, scientists from the Commonwealth Scientific and Industrial Research Organization (CSIRO), took a close look at the diets of 9,341 adult Australians – specifically, their “water-scarcity (缺少) footprints”.

The water-scarcity footprint is a widely recognized measurement of water consumption（消耗）. First, it counts the liters of water you used. Then, it looks at the place where the water was used. Using a liter of water in the desert is not the same as using a liter of water in a tropical (热带的) rainforest. The more scarce water is in your area, the larger your water-scarcity footprint.

The scientists found that the average Australian’s diet had a water-scarcity footprint of 362 liters per day. Snacks and beverages – cookies, cakes, sodas and alcohol – accounted for 25 percent of the water-scarcity footprint. The research also included a glass of wine (41 liters), a single serving of potato chips (23 liters), and a small bar of milk chocolate (21 liters). Not surprisingly, cutting out snacks would be the NO.1 priority if you wanted to lower your own water-scarcity footprint.

Climate change is causing droughts and extreme weather. In 2018, Cape Town, South Africa, nearly ran out of water due to a drought. Its freshwater reservoir(水库) stayed at just above 13.5 percent of full capacity. By 2030, a world of about 8.6 billion people will need 35 percent more water, and 50 percent more food, according to the United States National Intelligence Council.

So, we need to watch what we eat, not just for our personal health but for the health of our societies.

8 . UK-based supermarket Waitrose has been accused by social media users for selling tree leaves at 6 pounds.

Photos of various tree leaves packaged in plastic bags and arranged as flower bouquets (花束) went hot on social media lately, causing complaints because of the product’s price, six British pounds. Considering tree leaves can literally be picked up from the street this time of year, ifs understandable that some people went after Waitrose, accusing the supermarket of trying to make money by selling something that is actually free.

“A bag of actual leaves? I’ll sell you a bin bag of leaves for 10 pence,” one customer wrote.

“This has got to be from the drunk Monday morning meeting category of ideas,5, someone else commented.

Apparently, the unusual bouquets appeared on Waitrose supermarket shelves as a way to welcome autumn, and featured a sticker urging customers to “bring the outdoors inside”. ''Brighten up your home with freshly picked flowers whose pleasant scents refresh the season,95 the official product description read. “We source the best blooms from expert growers, and handle them gently so that they can look beautiful for longer.”

Despite the generally negative feedback on its autumn-themed product, the British supermarket proudly announced that the idea was inspired at the beginning of autumn by a demand from shoppers. ^Whatever we intend to offer, we base our decision on the demands from customers. Our customers love using these leaves to mix in with their seasonal flowers to brighten their homes,” a Waitrose spokesperson told The Sun.

Interestingly, there were those who seemed to somewhat justify the price tag of this bag of leaves. They said that those were obviously ‘‘high quality leaves”. Their claim might be true. But even a bottle of wine can be bought at the same price or less. It seems crazy to charge 6 pounds for a bag of leaves.

10 . There are many American expressions about insects - like bees, for example.

You might say you were as busy as a bee if you spent your weekend cleaning your house. In fact, you also might say you made a beeline for something if you went there right away. When we go to see a movie, my friend always makes a beeline for the place where they sell popcorn.

Here is an expression about bees that is not used much any more, but we like it anyway. If something was the best of its kind, you might say it was the bee's knees. Now, we admit that we do not know how this expression developed. If fact, we do not even know if bees have knees!

If your friend cannot stop talking about something because she thinks it is important, you might say she has a bee in her bonnet. If someone asks you a personal question, you might say "that is none of your beeswax." This means none of your business.

Hornets are bee-like insects that sometimes attack people. If you are really angry, you might say you are mad as a hornet. And if you stir up a hornet's nest, you create trouble or problems.

Butterflies are beautiful insects, but you would not want to have butterflies in your stomach. That means to be nervous about having to do something, like speaking in front of a crowd. You would also not want to have ants in your pants. That is, to be restless and unable to sit still.

Here are some expressions about plain old bugs, another word for insects. If a friend keeps asking you to do something you do not want to do, you might ask him to leave you alone or "stop bugging me." A friend also might tell you again and again to do something. If so, you might say he put a bug in your ear.

If you were reading a book in your warm bed on a cold winter's day, you might say you were snug as a bug in a rug. And, if you wish someone good night, you might say, "sleep tight — don't let the bed bugs bite."
