1 . Recycling is good for our planet, but it can be confusing. Can I recycle plastic bags? What about pizza cartons? Toothpaste tubes? Which bin should I use? There are so many questions, and more than half of Americans are unsure about how to recycle.     1     Here’s a handy four-step guide on how to recycle effectively:

Know what to put in the recycling bin. Keep it simple and focus on the most commonly recycled items, such as paper, glass, aluminum and plastic.     2     Don’t use the recycled symbol as a guide. “The number on the container is really for people to identify the type of resin (树脂). That’s not helpful for the common consumer,” said Cody Marshall, a strategist at nonprofit Recycling Partnership.

    3     It is really important to know what you cannot put in your bin. You can always check with your city or at BeRecycled.org. If you live in the US, just plug in your postcode to search. Recycling companies struggle with the same problem items: hoses (软管), cords, needles and clothing, according to Marshall, so don’t put those items in your bin.

Wash or clean items. Do a quick clean to make sure there is no food left in containers before you put them in the bin.     4     Save food for composting (堆肥) in your garden.

Don’t bag it. Unless you live in a place that requires it, like New York City, keep the recyclables lost in the bin. “A lot of the time, it’s not safe for our employees to tear those bags open, or it takes too much time,” said Keller. “    5    ”

World Water Day,     1     (hold)on 22 March every year since 1993, focuses on the importance of freshwater. World Water Day celebrates water and     2     (raise)awareness of the 2.2 billion people living without access to safe water. It is about     3     (take)action to handle the global water crisis. A core focus of World Water Day is to support the achievement of Sustainable Development Goal 6: water and sanitation for all by 2030.

Food delivery apps are changing the way we eat

It’s raining, it’s dinnertime, and the fridge is nearly empty. Years ago, we made do; today, we order food through our phones. Within twenty minutes, we get whatever it was we were craving, we’re warm and dry, and there’s not a single dish to wash afterward.

Food delivery apps have altered the     1     of how eat, particularly in big cities. The industry is a complex machine; there’s Meituan, Ele.me, Hema…the list goes on. These companies are     2     and changing at a rapid rate, bringing on the rise of virtual restaurants and ghost kitchens, and customers who will never step inside a brick-and-mortar shop（实体店）.

Of course, these apps bring all types of cuisines around the city to our fingertips, but it comes at a cost. And one of the real environmental     3     lies in all that plastic and excess food.

In the US alone, packaging accounts for 30 percent of municipal solid waste. In 2017, that meant 80.1 million tons. Food delivery systems are likely     4     this huge number to rise. Durable materials like the plastics serveware is made from, are difficulty to     5     of.

Restaurant delivery is a global phenomenon – as is the impact on the environment. Meituan, one of the leading Chinese delivery platforms, delivered 6.4 billion food orders in 2018. It is estimated that China     6     1.6 million tons of packaging waste(containers, utensils, plastic bags) in 2017, nine times more than in 2015.

In the EU, University of Manchester researchers estimate, over two billion single-use takeaway containers are used every year. Most of those are not     7    . According to the European Commission, packaging, which includes plastic utensils, plates, and straws, make up 70% of all     8     pollution found in European seas.

Plastic bans,     9     packaging materials, and other efforts to cut down on waste are on the rise. Food delivery apps should, too, do their part to raise awareness for plastic pollution and     10     the gap between food waste and hunger.

5 . When you throw something in the recycling bin, do you think about what it could become? And when you do, does it make you more likely to use that recycling bin? Recently, a study was conducted in an effort to decide whether or not explaining to people what their recyclables are transformed into would help increase recycling rates.

The researchers started with a group of 111 college students, asked to draw on paper before watching one of three ads.One was a public service message that showed paper going into recycling bins.The other two also showed the paper either being transformed into new paper or a guitar.After completing a survey, the students were asked to deal with the paper when they left. Half of those who saw the first ad recycled their paper, while the recycling rate jumped to 80% for those who'd seen the other ads.

After doing a few more lab experiments, the researchers headed into the real world.At a party, volunteers spoke with attendees (出席者) about recycling, with half mentioning transformed products and half keeping it general.They discovered the subject of the talks came into play.After the game, the recycling and trash bags were weighed.Those who received a message recycled over half of their waste, while those who did not recycled less than a fifth.

All this is to say that details matter.People want to know what treasures their trash can become, and when that's laid out clearly, they' re more likely to do it.Perhaps recycling companies should redesign signs to describe the items being created.Recycling is far from a perfect solution,but it doesn't hurt to manage to improve its rates.

6 . Generally speaking, convenience and safety affect how we choose to pay for things. Environmental concerns do, too.

Each time you pull out a credit, use a phone’s wallet app or hand over cash, you take part in a system. Some parts of that system make things, like coins, bills or cards. Other parts move money between buyers, sellers, banks and others. Used cash, cards and equipment will be eventually disposed of (处理), as well. Each part of this system uses materials and energy. And all parts produce waste.

Now researchers are looking more closely at how “green” these payment systems are. They’re finding buyers can help cut some of the environmental costs, no matter how they pay.

To understand the full “cost” to society of money or any other system, researchers can perform what’s called a life-cycle assessment. It looks at all the environmental impacts of a product or process. It starts with mining, growing or making the raw materials. It includes what happens while something is in use. And it considers the final disposal or reuse of things.

Even though raw materials are the first step, in fact there are raw materials added in at every single step along the journey. For money, raw materials go into each step of something that is “made”. Fuels are the raw materials for energy to make products and transport them. More energy goes into using products. Recycling or disposal also requires energy, plus water, soil or other materials.

People don’t realize most of those steps, so they can’t judge if one form of payment is dirtier or more costly. And that’s a problem, researchers say. It’s also what has got some of them to show more about the costs of how we pay for our lifestyles.

A life-cycle assessment doesn’t tell you what to do. However, it gives you an informed basis for making a decision.

7 . Time is running out for coral reefs as the climate gets hotter. So scientists are searching the globe for corals that are better at enduring heat, Now, new research shows how those “super corals” can survive: less roommate drama.

Reefs depend on a crucial partnership between the corals and the algae (海藻) that live in the corals’ tissue, The algae make food for the corals using sunlight and in exchange, get a nice spot to live. But when oceans heat up, that relationship goes bad, and the corals kick the algae out, Without their roommates, corals can die, turning a ghostly white, bleached (白化) color.

Still, some corals seem to resist bleaching better than others, A new study shows that those corals depend on algae that are better at tolerating heat. Researchers hope that pinpointing these abilities will help develop new conservation tools to preserve the world’s reefs as temperatures rise. About 1/4 of all marine life rely on coral reefs in some way, along with half 1 billion people around the world also depend on reefs for their food and livelihoods.

“Heat stress can kill a lot of corals really fast,” says Kate Quigley, a research scientist at James Cook University and the Minderoo Foundation in Australia. “I hope that nature does have some mechanisms to get us through the next few years while we get our act together.”

While the hope is that those algae could also aid in reef conservation in the future, researcher Patrick Buerger says it’s likely that it wouldn’t help all coral species. And even the toughest corals can only endure so much. Currently, the world is on track for just under 3degrees Celsius of warming by 2100, a level that would wipe out nearly all coral reefs.

“The action has to be on climate change,” he says. “This is a short-term solution that might buy some time for corals to adapt. But the main focus has to be on climate. There’s not a silver bullet to the problem.”

8 . The Twenty-three-year-old Mumbai girl Vidhi Bubna is offering India’s first and only diving grant to explore the marine ecosystem.

Vidhi’s first diving experience turned out to be a heartbreaking one. While she expected a lot of colors underwater as she had seen on TV, Vidhi came across all white corals (珊瑚), which means they are almost dead from being bleached (褪色).

“It was very sad and I just started crying after coming out of the water,” she says.

Vidhi, an economics graduate from Ashoka University, did not enjoy working with numbers and turned to writing about social issues, including women’s rights and minority issues.

As an adventure lover, Vidhi went diving to explore the underwater beauty last year. Her disappointment at seeing dying corals led to the start of Coral Warriors, anon-profit organization that aims to raise awareness of marine protection and climate change.

“Nobody knows about climate change till they see it,” Vidhi says. The Mumbai-based organisation offers India’s first and only diving grant. The grant sponsors level-one scuba diving education in any location of their choice in India. While there is no specific standard, Vidhi says the selection process is strict, choosing candidates who are passionate about climate change and seeing that they do something of their choice. Four candidates have been awarded the grant so far and the organisation hopes to find at least five people every year.

“After the candidates return, we expect them to work on a climate change project of their choice, create communities, and work to create awareness and drive action-centric projects,” she explains.

Prior to starting coral warriors, Vidhi was hosting free online workshops to spread awareness of marine biodiversity and climate change, and has reached about 5, 000 people through them.

As a next step, Vidhi is planning to work on documentaries with high-quality underwater images and videos, considering not many can afford or have the courage to go diving to see what is happening underwater.
