Jiangxi Poyang Lake Nanji Wetlands

Nanji Wetlands is located in the southern part of the main lake area of Poyang Lake, covering a total area of 33,300 hectares. It is an incredibly valuable ecosystem and serves as a vital habitat for various wetland bird species, including many national first-class and second-class protected animals.

Anhui Shengjin Lake National Nature Reserve

The Anhui Shengjin Lake National Nature Reserve is a freshwater lake wetland, with an area of 33,333 hectares. It is primarily set up as the wintering grounds of rare birds. Within the reserve, there are a total of 142 bird species, including 66 species of migratory (迁徙的) birds. This reserve holds the distinction of being the largest natural wintering ground for the hooded crane (丹顶鹤) population worldwide.

Gansu Yellow River Shouqu Wetlands

The Gansu Yellow River Shouqu National Nature Reserve is located within Maqu county. It covers a total area of 203,401 hectares, with 132,067 hectares intended for wetland conservation. The primary objective of this reserve is to protect the highland wetland ecosystem, as well as the habitat of migratory birds, particularly the black-necked crane. In February 2020, it was officially approved as a Wetland of International Importance.

Guangdong Nanpeng Islands Reserve

Established in 2003, Guangdong Nanpeng Islands Reserve covers a total area of 35,679 hectares. In 2015, it was recognized and included in the International Important Wetlands Directory.

5 . It is late autumn—millions of gardeners across the northern hemisphere, pulled on their thickest sweaters, spent hours clearing large piles of leaves and packed them into plastic bags at the end of driveways.

In the US alone, nearly 10 million tonnes of garden waste go to landfill every year. That is a large amount of effort, not just from an environmental viewpoint but from that of our aching backs, too. So where does this advice come from? Well, it largely comes from the belief that thick fallen leaves can make plants under them unable to breathe, especially shorter grass. They shut down important photosynthesis (光合作用) and get in the way of the growth of the shorter grass. However, this received wisdom has recently been questioned by researchers at Wisconsin University.

The key finding of their new research was that although clearing fallen leaves is one of the most common gardening practices, it makes very little sense. In natural ecosystems, fallen leaves help return nutrients necessary for healthy plant growth to the soil, which greatly improves soil condition. Removing leaves year after year breaks this ecological (生态的) balance. Letting some leaves stick around to cover your garden is a great way to help your grass and the local ecosystem.

They further explained that if up to 50percent of your grass lawn (草坪) is covered by fallen leaves, you might as well go back indoors and put your feet up. The advantages of this light leaf coverage far outweigh the disadvantages—the leaves will quickly break down and help next year’s lawn grow far better than if you had cleared them. Only at over 50 percent coverage do the Wisconsin researchers recommend clearing.

So why not consider leaving the leaves? Save time, carbon and effort, and in exchange get a healthier lawn from this garden waste—that seems like a pretty good deal. And how many plastic bags could be saved by simply not binning fallen leaves every year? In the US alone, about 700 million.

6 . It was July 15, 2021, and my friends had helped me celebrate my 31st birthday.

Earlier in the day I had prepared for the _________ event of a flood. We are about a third of a mile from the banks of the Ahr River. It had been raining heavily that week, and the government had issued a flood _________, though not for where I was. _________, I’d placed sandbags on the floor outside my garden door just in case _________ got through. Before my friends left, they _________ me for doing that, but I thought, why take a chance?

As I drifted off to sleep, I was awakened by the _________ of rushing water, as if I were lying beside a waterfall instead of in my bedroom. When I moved my legs off the bed, I was _________ by the touch of cold water lapping against my knees and rising fast. Trembling and in darkness, I _________ my cellphone and turned on the flashlight. I saw water was shooting through the gaps of the garden door.

I admit it, I began to _________. The Ahr, usually such a __________, slow-moving river, had violently burst its banks. And now I had to get out—fast!

Any effects of the celebratory drinks I’d had earlier were now gone. I heard the garden door starting to crack under the __________ of the flood. In bare feet, I started to move to my only __________: the door that leads to the hallway. All around me things were breaking, and the cupboards were being __________.

I tried to pull the door open, but the force of the water wouldn’t __________ me. Finally, I __________ to make a gap of about a foot, just wide enough to squeeze through and make it into the __________.

If I had __________ just a few minutes later, I would have drowned. Many of the houses around us were destroyed, including, __________, a home for the disabled. Not everyone got out.

I came close to drowning that day. But rather than keep thinking about that, I prefer to __________ what my mother told me afterward: “Christian, don’t remember the day when you lost everything. Remember the day you __________.”
