3 . Much of the Amazon’s biodiversity (生物多样性) is under fire-literally. In the last two decades, deforestation (滥伐) and forest fire ate into the ranges of thousands of plant and animal species in the Amazon rainforest.

The extent of the damage is closely tied to the practice of laws in Brazil aimed at protecting the forest from widespread logging (伐木). The findings illustrate the key role that forest use laws have in the fortune of the Amazon rainforest.

Threats to the survival of this biodiversity could have long-term effects. Biodiversity promotes a forest’s resistance to drought. If fire-impacted area continues to rise, not only does the Amazon lose forest cover, but also some of its capacity to deal with the changing climate.

“With fires advancing deeper into the rainforest, more species will experience fire for the first time. These species have not evolved (进化) under conditions with regular fires, so the consequences for those species, like increased risk of population declines or extinction, can be severe,” says Xiao Feng, a biogeographer at Florida State University.

“But we don’t know how fires are impacting the biodiversity across the Amazon basin,” says Feng. The Amazon is a huge area. It’s generally impossible to go there and count the number of species before the fire and after it. So Feng and his team instead investigated how Amazonian plant and animal species’ geographic ranges have been affected by recent fires. The team gathered range maps of 11,514 plant and 3,079 animal species and compared these maps with satellite images of Amazon forest cover from 2001 to 2019. Those images let the team track how logging and fires have led to the reduction of rainforest.

Starting in 2009, when a series of rules aimed at reducing deforestation started being performed, the extent of fires generally decreased. Then in 2019, fires rose back up again, co-occurring with a relaxation of rules. Much of the fire-driven forest loss was concentrated along the more intensely logged southern reaches of the rainforest.

The change suggests effective forest protection laws can slow this trend of destruction and are essential for preventing the region from reaching a tipping point.

4 . A four-year-old boy who was crazy about collecting rubbish has finally fulfilled his dream of being a cleaner. Riley McCourt has admired the local rubbish collectors for ages, spending his days picking up waste on his street and wheeling bins (垃圾桶) to the side of the road to help out his neighbors. He loves cleaning and binning waste. His favorite chore is to empty the rubbish from the chip shop his mum runs. Two weeks ago, however, a disaster struck: Riley accidentally knocked over one of the bins and was accused of causing trouble.

Someone posted in the local Facebook group that Riley had put rubbish in the street, clearly unaware of his love for keeping the streets clean. Thankfully his innocence was quickly proven, and his local council decided to make his dreams come true by allowing him to work alongside the cleaners for a day.

Riley joined the waste collection crew on Wednesday, chatting with the team, helping with the recycling, and riding in the waste collection vehicles. He even got his own jacket. Riley's mum, Toni McCourt, said, “He loves the bins and trucks.” Riley's favorite day is definitely bin day. He goes round collecting the rubbish up on the street. The cleaners all know him when they spot him. He goes outside as soon as he sees them come round. He helps his neighbors put their bins out for collection.

Riley clearly made a good impression during his first day on the job, as community services manager Jane Carrol said she was very pleased with his enthusiasm for the role. Jane said, “Riley is clearly a keen recycler and who knows, when he is older I'm sure he would make an excellent member of the team here. It was a pleasure for the team to show him around the vehicles.”

6 . There you are in your favorite clothing store. You don’t really need to buy anything, but everything is so cheap and stylish! Before you know it, you leave the store with bags and bags of new clothes.

On the surface, this doesn’t seem so bad. However, there are a lot of hidden costs behind the cheap price tags (标牌). To put it plainly, the fashion industry is terrible for the planet. Not only does it use up a lot of resources, but it also heavily pollutes the environment with chemicals, microplastics and unwanted waste.

Fashion is one of the least sustainable industries on the planet, commented Michael Stanley-Jones. “We’ve all become our own waste managers, hoarding fashion waste in our houses,” he noted.

It doesn’t just take up space in our cupboards, though. It also ends up in landfills (垃圾场), too. But, thankfully, the fashion trend tides are changing. People are increasingly examining their own consumption and what changes they can make to become sustainable, Jane Fellner, founder and CEO of sustainable fashion seller Loopster, told the Guardian.

In particular, with its typically lower prices and rare fashion finds, shopping secondhand   has become an increasingly popular and eco-friendly option. According to online reseller ThredUp, the secondhand market is predicted to reach $80 billion by 2029. And, although fast fashion will continue to grow 20 percent over the next 10 years, secondhand fashion is expected to grow an unbelievable 185 percent in that same amount of time. Fellner continued: “Secondhand has become more socially acceptable. Thrifting (节约) is now massive on TikTok.”

The only true sustainable way to shop is to not shop at all, unless you’re buying clothes that already exist.

7 . A food service app is allowing customers to buy restaurant food at a low price before it goes into the waste bin.

Too Good To Go provides buyers with a bag of nearly wasted, but perfectly good food for takeaways as a way to cut food waste and help support the restaurant industry.     1     The app is one of the several winners of Fast Company's 2021 World Changing Ideas Award, which reports that 40% of the food in America is wasted.

    2     However, it's possible to know how many meals the app has prevented from going there. Originally sold only in a few selected American cities, 200,000 meals have been sold.     3     And over 1,500 restaurants have signed up in cities like New York, Boston, and Los Angeles. At present, 150,000 orders are going out the door per day in 15 countries.     4    

It is also easier for the restaurants since it's nearly impossible to guess and predict what will be available at the end of any night. Decomposing（分解）food in landfills is a major source of methane（甲烷）, which can cause climate—related damage before completely decomposing after a decade. “We think we can save more than 2 million meals from the trash in the U.S. in 2021.     5    ” said Lucie Basch, co-founder of Too Good To Go.

8 . Laura Stone is the founder of Sydney by Kayak（皮划艇）, a company that offers guided kayak tours of Sydney Harbor in Australia. Not only did their business increase during the COVID-19, but one of their tours is actually more popular than ever.

A few years ago, Laura was paddling in the harbor when she noticed trash floating in the water. For reference, the United Nations Environment Program (UNEP) estimates that about 8 million tons of plastic end up in our oceans each year, causing big problems for wildlife and local plants. Laura was so shocked by the garbage in the water that she decided to dedicate a few paddles each week to trash cleanup. Incredibly, her clients were immediately on board with the idea, so Sydney by Kayak now leads four to five garbage-collecting tours every week!

At the start of the COVID-19, Laura thought her business would drop off as many others had. Instead, desperate for purpose and a way to get outdoors, people flocked to her “Clean Up Kayak” tours. They now routinely take about 441 pounds of garbage out of the harbor each week! “We've been quite surprised, even through the COVID-19, we've been very busy,” Laura said. “Because they can't travel, people are looking for something to do. That is not just good for them, but also good for the environment. ”

Each tour begins with participants preparing with some working tools. Some people come back many times for the satisfaction of collecting trash from the harbor. Julie Greening, for example, has done about 10 tours so far and says “every little bit is worth it”. “We're 7 billion people on this planet, so everyone does a little, but of course it's going to help, ” she said. “It's got to. ”

10 . Understanding the link between a clean environment and human life is not a new concept. In fact, it was noticed as early as ancient Rome. Today we see how green living has infiluenced our everyday lives. There is a growing community of people who embrace a zero waste lifestyle and make changes to the way they live to reduce their carbon footprint.

Living a zero waste lifestyle means doing one’s best to achieve the aim of not sending anything to a landfill. People who adopt this lifestyle ultimately cut down on their waste by reducing what they need and want. They reuse what they own, sending few things to be recycled.

Many people who adopt the zero waste lifestyle claim to be frustrated by the many harmful chemical substances found in beauty and cleaning products. They also find the uses of disposable items and excessive packaging. For example, how many times have we had to peel away layers of plastic wrap and cardboard before finally taking out the item which we had bought? Instead of buying pre-packed food and goods, those who identify with the zero waste philosophy tend to shop in stores that allow them to make purchases and bring their own cloth bags and glass jars to store their purchases.

Many people may have the misconception that it is easier to live a zero waste lifestyle in the West. Nevertheless, Malaysian environmental journalist, Ms. Aurora Tin, has proven that a zero waste lifestyle is possible even in the Asian context. Instead of going to the supermarket to buy pre-packaged foods, Ms. Tin now visits the wet market and brings her own bags for vegetables. She has even stopped using store-bought toothpaste and makes her own toothpaste from coconut oil and baking soda. This lifestyle may be too big a change for the average person, but we could follow her suit to make gradual changes to our own lives.
