1 . Earthquake safety tips

On April 14, 2010, a big earthquake hit Yushu, Qinghai. Over, 2,000 people died. Many people were hurt. Why are there earthquakes?

The surface of the Earth has many pieces. These pieces are always moving. When two pieces move past each other, there is an earthquake.

Scientist are working hard to find out more about earthquakes. They try to predict (预测) them, but it's very hard.

Do you know how to get ready for an earthquake? Do you know what to do during an earthquake? Here are some things you should know.

What to do before an earthquake:

Make sure you have two bottles of water, a packet of biscuits, a clean towel, a few band-aids (创口贴), a radio and a flashlight (电筒) at home.

What to do during an earthquake If you are inside:

★Stay where you are. Quickly move under a strong desk, or along a wall. This will protect you from falling things.

★Don't stand near windows.

★Turn off the lights.

★Don't get into a lift during an earthquake. If your are in a lift, get out as quickly as possible.

If you are outside:

★Don't stand near buildings. Things may fall on you.

★Lie on the ground until the shaking stops.

3 . Off the coast of Formentera, an island, lives seagrass that stretches 15 km. The seagrass, covering several kilometers, is made up of a single organism. The grasses are also long-lived, for tens or hundreds of thousands of years. Along with two other kinds of coastal ecosystem—mangrove swamps and tidal marshes—seagrass fields are particularly good at taking carbon dioxide from the air.

This role was highlighted in a report published on March 2nd by UNESCO, on “blue carbon” —the carbon stored by Earth’s oceanic and coastal ecosystems. In total around 3,300 million tons of carbon dioxide (about three-quarters of the world’s emissions in 2019) are locked away in the planet’s blue-carbon sinks. Research by Carlos Duarte, the report’s author and an ecologist, has shown that one hectare of seagrass can suck as much carbon dioxide each year as 15 hectares of rainforest.

One reason that blue-carbon ecosystems make such effective sinks is that underwater forests are thicker than the land-based woods. They can also trap floating pieces and organic matter, which settles on the sea floor and can double the amount of carbon stored away. They possess another advantage, too. Climate change is leading to more wildfires around the world. As forests burn, their carbon stocks are sent back into the atmosphere. Unlike forests on land, blue-carbon ecosystems do not burn.

Blue-carbon ecosystems may not be fired, but they remain affected by other sorts of disasters. In May 2020 cyclone Amphan destroyed 1,200 square kilometers of mangrove forests. A marine heatwave in Australian waters in 2010 and 2011 damaged around one third of the world’s largest seagrass field in Shark Bay. Mangrove forests can weaken or control waves and provide natural barriers to storm surges. Protecting and expanding them, then, appears to be a must.

Covering 7 million square kilometers of jungle and river over eight countries, the Amazon Rainforest is home to millions of sorts of plants and animals, some of     1     are still being discovered today. It's also the world’s     2    (large) supplier of oxygen and is a treasure chest for medical     3    (researcher) who are experimenting with different plants in hopes of finding cures for certain diseases.    4    , the world is at risk of losing this rich rainforest because of deforestation (滥伐森林)    5     (cause) by the actions of farmers, loggers and settlers.

The Amazon Basin     6    (lose) 20% of its rainforest since 1970. Cattle farmers have     7    (continuous) cleared the land for cows     8    (eat) on and crop farmers have begun “slash and burn” (刀耕火种), a farming method that involves cutting down forests and burning the land to make     9     suitable for agricultural purpose. Loggers have been cutting down the trees for timber(木材), further decreasing its size.

With the destruction of the Amazon Rainforest, global warming becomes more of a threat. It is up to each individual to fight against the     10    (disappear) of the Amazon by making the world know something about this environmental disaster.

I have swum with sea lions in the Galapagos Islands, _______ lemurs (狐猴) sing and dance in Madagascar, and had many other amazing _______. I have also become increasingly aware of the changes _______ by human activities. Some of the special places I so _______ are no longer around today. My inspiration to protect rainforests comes from a particular ________ in the rainforest of Borneo when an area of ________ was destroyed by loggers (伐木工).

Today I ________ a great deal of time reading, writing, traveling to rainforests, and talking with scientists doing research on them. My ________ is to raise awareness, interest, and appreciation of wild-lands like rainforests.

7 . An Ontario teen is making waves by turning old fishing gear into new treasures. Since last year, Natalie, 15, has been taking lost or thrown — away fishing nets and rope and transforming them into bracelets, rope art, mats, baskets and necklaces.

Last year, Natalie was working on an assignment for her science, technology, engineering and mathematics (STEM) class. As part of the assignment, she learned about “ghost nets”, which are fishing nets that have been left or lost in the ocean by people who fish.

“They have huge effects on our environment. They can kill coral reefs and many animals,” said Natalie. “46 percent of the Pacific garbage is ghost gear.” The Great Pacific Garbage is a huge collection of trash floating in the Pacific Ocean between Hawaii and California.

Natalie told her mom she wanted to do something to help. She got in touch with a handful of charities, including the Sea Protection Society and Coastal Action.

After getting some shipments of ghost nets and rope from those organizations, Natalie, with the help of her family, started turning the discarded gear into new artworks. “We've made bracelets, rope art, mats, baskets, and we've made necklaces, which also use beach glass in them,” she said. Natalie then started selling the artworks online, the crafty buying and selling website.

She donated all her profits-minus a small sum of change to cover supplies — to the charities that donated fishing supplies to her. She's also been donating all the income from her non-profit business, called Nautical Waters, to charity. Natalie said she hoped to continue her passion for ocean life, with plans to study marine biology in university.

8 . The good news is that more people bought electric vehicles （EVs） in 2020. The bad news is that sport utility （多用途的）vehicles （SUVs） continued to grow in popularity, too. “The fall in oil consumption due to the first trend was completely canceled out by the second," said Laura Cozzi, an officer at the International Energy Agency （JEA）,

Between 2010 and 2020, global carbon dioxide emissions （排放）from conventional cars fell by nearly 35 billion Lons, due to reasons such as fuel efficiency improvements as well as the switch to electric cars. Emissions from SUVs rose by more than 50 billion tons. "While the growth in EVs is encouraging, the boom in SUVs is heart-breaking," says Peters at the Cicero Climate Research Centre in Norway.

There are many reasons for the growing popularity of SUVs. For example, rising economic boom in many countries means more people are able to afford them. Some people see them as status symbols. Also, SUVs are heavily advertised by car-makers, whose profit is higher on these vehicles. Some countries, including France, have introduced plans under which more taxes are paid on heavier cars. But Peters thinks that people who are rich enough to afford SUVs won't be deterred by slightly higher taxes. "There are now some electric SUVs available, but 1 hope one day you will see more electric vehicles brought to the SUV market," says Peters.

Even if it happens, switching to electric SUVs isn't a good solution. Due to their size and bigger batteries, it takes more resources to build electric SUVs, and they consume around 15 percent more electricity. That means higher emissions unless the electricity comes entirely from renewable sources, and higher electricity demand makes it harder to green the electricity supply.

9 . 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.
