1 . The first time ever I realized that plastic was a serious matter for our planet was during a road trip in Western Australia, almost 12 years ago.

We ________ at a supermarket along the Coral Bay coast to buy some groceries and the lady at the counter told us they didn’t sell any shopping bags in order to prevent plastic in the ________ and to help preserving the endangered turtles living in that area. After a first reaction of surprise, we ________ all our shopping in our arms and left.

This was just one of the many experiences I’ve lived that made me more ________ about my impact and pushed me to adopt different habits to live and ________ more sustainably.

Our trip to Borneo was another life-changing ________ that has strengthened my resolution to a zero-waste lifestyle. While traveling in some countries, we came to know that ________ drinking water was always a challenge. So we had to travel with our water bottle, and we ________ to avoid using plastic during our trip.

Besides, we were also ________ impressed by our stay on Libaran Island. A sustainable turtle conservation ________ and the community had made big efforts to ________ the beaches and creatively reuse plastic for ten years. Despite that, the shore is ________ daily with tons of plastic coming from the tides.

Facing this global issue ________, raised in me a feeling of sadness and anger that soon turned into ________: to do as much as possible to reduce plastic in our life. Small changes can ________ a difference!

3 . Solar stills (蒸馏器) provide a clever and simple means of purifying dirty or salty water, but they work at a rather slow rate. A new material has been shown to boost their performance, and it’s made from fruit waste which would otherwise be thrown away.

In its most basic form, a conventional solar still consists of a basin of undrinkable water that is set beneath a cover. The water evaporates (蒸发) as it’s heated by the sun, condensing (凝结) on the inside surface of the cover. That condensation—which is pure, clean water-drops down the cover and is collected in a separate container for drinking. In order to warm the dirty/salty water at a faster rate, scientists have developed materials that float on its surface, transforming sunlight into heat. They commonly use carbon obtained from coal.

To seek a less costly and more environmentally-friendly alternative, Prof. Edison and colleagues at Singapore’s Nanyang Technological University looked to something that is free for the taking—fruit waste. More specifically, the scientists tried out coconut peels, orange peels and banana peels.

In a simple carbonization process, the fruit waste was heated at 850℃for a few hours, and mixed with a kind of chemical substance. Doing so transformed the fruit waste into a new material which has a very highlight-to-heat transforming efficiency.

When tested in a small solar still, this new material proved to be very effective at transforming sunlight into heat, causing the dirty/salty water to evaporate much more rapidly. And because the material is full of holes, the waters team is able to rise right through it, subsequently condensing on the inside of the still’s cover.

Prof. Edison and his team found material obtained from the coconut peels worked best, as it transformed sunlight to heat with an efficiency rate of 94%. They are now developing the technology further, and are seeking industry partners to help with its commercialization.

5 . China’s second national botanical (植物学的) garden, South China National Botanical Garden, was set up in Guangzhou on July 11th, 2022.

With a total of 319 hectares of core functional area planned, the new national botanical garden was built based on South China Botanical Garden. It spans Guangzhou and Zhaoqing, two cities in Guangdong Province.

The South China National Botanical Garden aims to strengthen the conservation, scientific research and knowledge broadcasting of tropical (热带的) and subtropical (亚热带的) plants. The garden has three research centers, two national-level field stations and three key laboratories of the Chinese Academy of Sciences. There are 17, 168 protected plants, 643 rare and endangered plants, and 337 national key wild protected plants in the garden at present.

The garden will participate in plant diversity protection both in China and the world and achieve the conservation goal of 20, 000 species. Meanwhile, it aims to play a world-leading role in collection and storage of living plants, among which 6, 000 species are economic plants.

Besides, 95 percent of rare and endangered plants in South China will be effectively protected, thus to provide plant resources for green development.

China is one of the countries in the world with the richest biodiversity, having more than 37, 000 known species of higher plants, accounting for about one tenth of the world’s total.

The South China National Botanical Garden, together with the national botanical garden in Beijing, has formed a system of collection and complete the retention of wild plant groups, which is helpful to maintain the country’s plant diversity.

8 . John “Charlie” Veron-widely known as “the Godfather of Coral Reef (珊瑚礁)”-is a celebrated expert who has personally discovered nearly a quarter of the world’s coral species and has spent the past 45 years diving Australia’s Great Barrier Reef. But now the 73-year-old is raising the alarm about its future. The Great Barrier Reef, one of the natural wonders, is 2, 300 kilometers long and is the only living organism that can be seen from space. It is considered a World Treasure Site due to its biodiversity (生物多样性)with 30 species of whales, dolphins and sharks. Within the reef itself, there are also a number of tiny organisms and fishes.

However, its health is threatened. After the recent mass bleaching (白化)events, Veron dived in many areas of the Great Barrier Reef to see the damage for himself. “I was seeing and feeling it and it was absolutely shocking, ” he says.

Veron says the mass bleaching events in the past few years-and the possibility of losing one of nature’s greatest treasures-were a wake-up call for the world in the wider battle against climate change, which, together with the rising sea temperature, is considered the greatest threats to the reef.

Fortunately, earlier this year, the Australian government announced nearly 400 million dollars in new funding towards scientific projects designed to help the reef.

There has been criticism in Australia about the slow process for the funding. “It won’t be wasted, though,”Veron says. “As scientists will be able to create a sort of seed bank to protect the species until the climate is good enough to rebuild the reef. What the scientists hope to do is to help nature along a bit after the big carbon dioxide increase is over and it starts to come down.”

9 . Do you know that about 71 percent of our planet is covered by the ocean (海洋) ?     1    . People around the world wear blue to celebrate World Oceans Day on 8 June every year. World Oceans Day is a special day for learning about oceans, including why they’re in danger and how essential it is to protect them.

Without oceans, life couldn’t exist. Scientists don’t know the exact number, but they think that oceans are home to 50 percent to 80 percent of all species on Earth, from large whales to tiny plankton. Oceans absorb carbon dioxide and give out oxygen (氧气).     2    .

Humans use the ocean in many different ways. Lots of our food comes from oceans.     3    . Besides getting oil and gas from beneath the ocean floor, we can produce electricity using the power of waves. We even rely on submarine cables for international communication.

    4    , but sadly they are in danger. You’ve heard of plastic pollution. Billions of pieces of plastic are floating around in our oceans, harming and killing sea creatures. It’s also dangerous for our health too, because fish eat the tiny pieces of plastic and then humans eat the fish.

For World Oceans Day, you can use social media platforms to share posts, photos or videos showing how important oceans are and why we need to protect them.     5    . Remember that every day we can make a difference by using less plastic and recycling, and talking to others about protecting our precious oceans.

10 . 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”.
