Marrakech (马拉喀什) is the fourth largest city in Morocco and has a rich architectural heritage. However, an earthquake in September caused serious damage     1     some of them in the city.

The Medina district, the old cultural center of Marrakech, was one of them.     2     (add) to UNESCO’s World Heritage List in 1985, the district is enclosed by 900-year-old walls built of red sandstone that once     3     (defend) the city against danger. However, large parts of these walls were damaged in the earthquake and long sections now show deep cracks     4     other parts have collapsed.

Apart from ancient walls, Morocco World News reported that the city’s Kharbouch Mosque (清真寺) was almost     5     (entire) destroyed. Before the earthquake, it was a cultural center for the city     6     dancers and storytellers performed. A local resident     7     (tell) The New Arab that the mosque dates back to the 17th century.

After visiting Marrakech     8     (follow) the destruction, Eric Falt, an officer at UNESCO, stressed that it was necessary to immediately plan for the     9     (construct) of damaged cultural assets (资产). The earthquake’s impact on Marrakech’s cultural heritage     10     (expect) to be a long-term challenge that will require careful restoration efforts, noted Morocco World News.

5 . For sharks, the Mesoamerican Reef, which stretches over 600 miles, is a busy highway. Sharks use it to find their way and it provides them with food and habitat.

But as with on-land highways, this superhighway can be dangerous. Overfishing, commercial development and illegal practices are endangering the species. “We’re seeing a continued decline in shark populations. Our goal is to turn that round.” says Rachel Graham, founder of Mar Alliance, a non-profit organization focused on conserving sharks.

By monitoring sharks, Mar Alliance can collect important knowledge on the species to help inform conservation and push for political action. But rather than acting in opposition to the local fishing community, MarAlliance enlists their help.

“They are the ones who are on the sea every single day,” says Graham, “and they’re the ones who decide the species’ future.”

MarAlliance employs up to 60 fishermen across its range, mostly on a project basis, training them to collect data, record and release fish. Not only does this provide an alternative income to fishing communities, making them less dependent on natural resources, but it also teaches them about the benefits of a healthy ocean ecosystem and how to fish sustainably.

Among them, Ivan Torres, who used to catch sharks to sell locally as food, has learned how critical they’re to the whole ecosystem, saying he’d never fish sharks any more.

If this attitude change continues to spread throughout fishing communities, Graham has hope for the shark populations. “The primary threat to sharks is unquestionably overfishing,” she says, “By reforming the industry, populations can bounce back.”

In 2020, Belize outlawed the use of gillnets, large panels of netting of trapping large sealife. The ban’s impact is already noticeable with a recorded 10-fold increase in shark populations.

But such regulations need to be copied along the whole superhighway for long-lasting impact, and countries need to find a sustainable balance between fishers and the fished. “We need to find a win-win strategy between fisher livelihoods and shark survival,” Graham emphasizes. “I hope that through education and providing an economic alternative for fishing communities, MarAlliance will help ensure safe passage for sharks along the reef”.

6 . Kathy Xu,a high school teacher,had always wanted to see a shark in the wild.The opportunity finally _______in 2011,when she went on a snorkelling trip to the Ningaloo Reef.She was so inspired by its beauty and grace that tears _______to her eyes.

Curious,Xu _______her bags and headed to the fish market.There,she spoke with several fishermen.Shark fishing is _______ risky and involves hard physical work,but it is one of few ways for them to_______for their families.“I told them I’d pay them to take _______out to see these snorkelling havens,“she says.Together, Xu and the fishermen came up with the idea of snorkelling boat trips,and a deal was_______.

In late 2012,Xu________her full-time job to focus on building The Dorsal Effect, an ecotourism business she hoped would help save the declining shark________.In 2019,Xu found a female Rhynchobatus cook, a relative of the shark.The species had not been seen for more than 20 years and was believed to be________.The discovery gave scientists hope,and it could be________ for an in-depth conservation study.

In the past decade,global demand for shark fins has________-a promising result of conservation campaigns.For now,Kathy,41,is proud of the small changes she sees happening on Lombok,from the fishermen who now have a new way to________an income to the schoolchildren who learn about sharks on tours with The Dorsal Effect.

7 . During the 2020 Olympics in Tokyo, there was a lot of talk about the environmental efforts taken. Athletes slept on beds made from recycled cardboard. The medals were produced out of old appliances such as smartphones and laptops. Over 90% of Japanese cities, towns and villages participated in the two-year effort to collect recycled materials to produce 5000 medals. Eighty tons of small electrical devices were collected to make this project successful.

With the 2024 Olympics Games underway in Paris, new environmental efforts are coming into play. Observers will sit on chairs made of plastic recycled from local bins. This decision was made due to a lack of unused raw materials to make new seats, so the eco-construction firm Le Pave turned to make the seats out of waste. Around 11,000 seats will be made from recycled materials.

The plastic collection for Paris 2024 has been carried out in the region’s schools, and over five million coloured bottle caps have been recovered. Moreover, 80% of the 100 tons of recycled plastic needed to make the seats come from the yellow bins collections. This is all part of the Paris 2024 “zero waste” strategy to limit single-use plastic usage and encourage a circular economy.

The Olympic Games organizers are planning to make the Paris 2024 Games the greenest Olympic Games yet. They intend to employ a carbon-neutral approach that will lessen the climate impact of the Games by predicting, avoiding, reducing and balancing emissions and encouraging others to get involved. The Summer Games have emitted 3.6 million tons of carbon emissions in previous years. The Paris 2024 Games has set a carbon budget of 1.5 million tons which includes the emissions from construction, transportation and operations of the Games.

These plans are ambitious but are achievable. If Paris 2024 successfully reduces emissions and promotes a circular economy, it might set the standard for future Olympic and Paralympic Games, regardless of where they are held.

10 . Large amounts of waste, or garbage, are filling streets in Nepal’s capital, Kathmandu, after protesters blocked a road leading to a landfill outside the city. People in Bancharedanda where the garbage is kept blame the government for not doing enough to protect them from the waste.

One British tourist, Richard McSorley, recently talked about the problem. He remembered how clean Kathmandu was when he first visited it many years ago. “If I were a new tourist, I would be despondent now,” McSorley said, while pointing to a load of garbage next to a city street. For weeks, treatment of waste has been a continuous problem in the city surrounded by hills. The problems started after people in the village of Bancharedanda refused to have the garbage thrown at a nearby landfill.

Biswas Dhungana was one of the protesters. He said the villagers were refusing to permit trucks loaded with garbage to enter. They say government officials have done little to provide basic equipment and effective ways to deal with the garbage. He added, “We have been forced to live like pigs in terrible conditions for several years as the government has not done anything to keep the village clean.”

Last week, hundreds of villagers built a wall of rocks on the road leading to Bancharedanda. It forced about 200 trucks filled with Kathmandu’s garbage to return without dumping their load. It was said that protesters also threw stones from surrounding hills.

Sunil Lamsal is an official to watch over how Kathmandu’s garbage is treated. He said, “I am working to deal with the concerns of the locals in Bancharedanda. But now, garbage continues to grow on the streets of Kathmandu. This has led to increased danger for people living in the capital. In the light of it, the government will soon take further positive measures to tackle the problem, as the environment affects every family.”
