A strong earthquake made Joseph Cadeau wake up from sleep on Saturday. Cadeau, a teenage boy,     1     (immediate) got up and ran out of his home in Les Cayes, a city in Haiti. On the way out, Cadeau was knocked out by rubble (碎石). Moments later, Cadeau moved out of the house with great     2     (difficult). Unable to walk, Cadeau lay down in the street.

Cadeau was one of at least 12,268 people     3    were injured during the earthquake. It struck Haiti’s southwest region around 8:30 am on Saturday,     4     (claim) at least 2,207 lives, according to Haiti’s Civil Protection agency.

Cadeau managed to get out of the rubble     5    his own. He was not sure how long he had lain in the street until he     6     (rush) to a health facility eventually by     7    stranger. When Cadeau reached the health facility, he had to wait since there were not     8     (sufficiency) health workers to take care of so many injured people. While he was waiting, Cadeau’s foot began swelling (肿胀).

“I received treatment too late, which is why my foot is swollen like that,” said the teenager, pointing at    9     (he) swollen foot. “Fortunately, I survived and have a chance     10     (rebuild) my hometown and give back to the society.”

4 . Off the coast of northeastern Queensland, Australia, near Magnetic Island in Florence Bay, the Great Barrier Reef corals (大堡礁珊瑚) are having a baby boom (激增).

“Every year there are more anrd more coral babies,” says Hillary Smith, an ecologist at ames Cook University in Australia.

That’s thanks to a simple but effective strategy for cleaning the region’s coral reefs: “seaweeding”. Like weeding (给……除杂草) a garden, seaweeding involves pulling big handfuls of large algae (水藻) off reefs and taking them away.

Experts say getting climate change under control is key to keeping the world’s reefs healthy. But meanwhile, local efforts such as seaweeding can help corals grow and reduce the effects of climate change.

The health of coral reefs around the world is dire: By 2050, 95 percent of the world’s coral could experience heat stress, according to a 2020 report by the Global Coral Reef Monitoring Network. Algae is a big problem: Already, algae cover has increased on two-thirds of reefs around the world, and one study published in 2021 showed that half the world’s coral reefs have died since the 1950s. Removing seaweed from reefs requires a great deal of work but is not complex, making it a good project for citizen scientists eager to help restore (恢复) reefs.

When the project first began in 2018, Smith says researchers weren’t sure if removing seaweed would benefit the reef or if removal might have the opposite effect in some way. But now, “It’s all looking really positive for the reef,” she says.

Volunteers are ready and waiting to help near Townsville and at other affected Australian reefs, says the Earthwatch Institute’s Fiona Wilson.“We need lots of willing hands to remove seaweed. It takes weeks of time,”she says. “But obviously recovery of the Great Barrier Reef is a passion for many people, so we draw volunteers.”

7 . Wondering what you can do to celebrate Earth Day on April 22? You’ve come to the right place. We’ve gathered a comprehensive list of Earth Day activities, both fun and environmentally-conscious, to help raise awareness and make a difference. If you’re ready to learn more about joining the global celebration, initiating real change, and doing your part to save our planet, read on!

·Walk or ride your bike.

    1     Plus, it’s a great way to involve physical activity into your daily routine, benefiting both your physical and mental well-being. Even one day can make a difference, but if you can commit to walking or biking more often in the future, that’s even better!

·Use a refillable water bottle.

Consider going with a stainless-steel refillable bottle for a super long-lasting option.     2     Using a refillable water bottle, meanwhile, protects the planet, saves you money, and protects your health.

·Plant a tree.

Pick a tree species that’s native to where you live. If you’re unsure, ask an employee at your local nursery or garden department. Choose the best planting spot to meet the tree’s needs, dig a properly sized hole, and water the tree well to give it a good start.     3     Try donating to a reputable environmental non-profit that will plant trees on your behalf instead.

·Visit a local farmer’s market.

Eating locally grown food is much better for the environment. For example, locally-grown food doesn’t have to be transported long distances to end up on grocery store shelves.     4

See if your community is holding an environmental fair. If your community doesn’t have one planned, consider starting one yourself! It’s the perfect day to get together for a fun and educational celebration of the Earth. Any money raised can go towards a local environmental restoration project or group.
