3 . Buildings, pollution, poor soil, insects, and even car crashes can add to tree loss. However, between 2016 and 2021, the city of Seattle in Washington state was reported to have lost about 255 hectares of tree covering, for which climate change was blamed. Then came the driest summer on Seattle’s record books in 2022. The drier conditions and hotter temperatures have left many trees with brown leaves, naked branches, and extreme seeding. These are all signs of tree stress.

According to Nicholas Johnson, a tree expert for Seattle City Parks, if this warming climate continues we are going to have a lot of trees die. Just like people, under the heat trees get weak.

Researchers from France and Australia studied the effect of hotter temperatures and less rain on more than 3,100 trees and plants in 164 cities across 78 countries. They found about half the trees in the cities were experiencing climate conditions beyond their limits. They also found that by 2050 nearly all trees planted in Australian cities will not survive.

It’s not the gradual change but these extreme swings of too much water, too little water, too much wind, and terrible storms that are going to cause these rapid changes. In 2005, Hurricane Katrina destroyed about 10 percent of the trees in New Orleans, Louisiana. And in 2021, Hurricane Ida uprooted many new tree plantings.

To settle the problem of tree loss, non-native trees have been brought to cities for some time. In the city of Bellevue, Washington, experts are growing different kinds of trees specifically for climate change. On city grounds, they are planting baby giant sequoias, just a few centimeters tall. The giant sequoias are not native to the Pacific Northwest area. But the trees can deal with the lack of rain and insects. Once these trees are established, they grow incredibly fast. Having many different kinds and ages of trees is important to keeping urban forests alive.

“Life always finds a way,” said Nicholas Johnson. “And in Seattle, people are helping life find a way.”

There was a job vacancy for taking care of the Great Barrier Reef!

Whether it was a genuine job offer     9     an eye-catching marketing event isn’t really important. The most important thing was that people all over the world became aware of the beauty of the ocean in the area. What’s more, they came to understand the delicate balance     10     the environment exists in and what can, and must, be done to protect the reef. That way, it will remain a safe habitat for wildlife and a dream destination for tourists.

6 . The idea that having narrow local focus leaves little room for anything but a selfish mindset is a misconception, according to a new study that found that concern for local affairs could help with global environmental conservation.

You might have heard of NIMBY which means “not in my back yard” and describes an individual or group opposed to a new addition to the neighborhood, typically a factory, roadway or power station. Nimbyism and parochialism(眼界狭小), which is a focus on a local area,   can go hand in hand, and there are concerns that parochialism paves the way for prejudice, narrowmindedness, and selfishness.

But researchers found the exact opposite to be true in a new study published. The researchers argue that positive parochialism can inspire a larger awareness of global environmental problems and encourage people to action.

“We did not find evidence that parochialism was necessarily negative and inward -looking,” said Patrick, a researcher for the study. “It can be those things, but there's no necessary conflict between feeling connected to your local area and feeling connected to the wider world. ”

For the study, the researchers reviewed documents from the 1987 Parish Maps project. The researchers showed how the Parish Maps project also demonstrated a passion for the environment and conservation. The researchers say that the Parish Maps project is a strong example of “positive parochialism”, and shows that thinking locally can influence a global mindset.

“For a long time,   it has been generally agreed that if we want people to think about global affairs they need an international worldview-but this may not be the case,” said Patrick. “Given where we are now in terms of trying to encourage people to make changes to help the environment, positive parochialism offers something that has been overlooked.”

Wang Tianchang and his family moved into the Gobi Desert 22 years ago. They have been fighting with the desert ever since,     1     (become) a symbol of China’s anti-desertification (防治荒漠化) campaign.

As     2     native of Gansu Province, Wang grew up with the Gobi Desert. In 1998, Wang’s family moved into the desert. They started planting bushes (灌木). To fund their efforts, they sold most of their farm animals and there were only 6 sheep left to support themselves. To make matters     3     (bad), the trees they had planted in the first two years     4     (blow) away by strong winds, because they weren't familiar with the environment. Then they learned that adaptable grasses were ideal for holding down the sand. A bush     5     (know) as the sweet-vetch has an 80 percent survival rate even in severe desert conditions,     6     has become a key part of the Wang’s efforts.

Now, although Wang is suffering from serious health     7     (problem) and is in his late 70s, he has no plans       8     (quit) his mission. His efforts have not gone unnoticed and have won several honors for his contributions     9     local greening. The Chinese government not only appointed (委任) Wang Tianchang and his sons as forest ranchers (大农场主), but also started funding their work. The family’s home is now surrounded by a     10     (beauty) vegetable garden, proving that land can in fact be transformed from the desert.

8 . If you’re a real fitness addict, you certainly know the ultimate running challenge is to take part in a marathon. It seems every major city and town around the world hosts an annual marathon, with thousands of athletes running an exhausting 42.1 kilometres. While many runners’ motivation is to beat their personal best and cross the finishing line without collapsing, they’re also doing it for a good cause — to generate funds for charity.

But like other major events, the marathon also generates a massive carbon footprint. Thousands travel – some by plane — to the location, and waste from food packaging and goody bags gets left behind by viewers and runners.

This is becoming a big issue for cities — how to host a worthwhile event, encouraging people to exercise and help charities, while protecting the environment? Several cities have developed formal plans to reduce their environmental impact and promote sustainable ideas. One event in Wales, for example, introduced recycling for old running kit. It’s something that this year’s London Marathon tried to tackle by reducing the number of drink stations on the running route, giving out water in paper cups and offering some drinks in eatable seaweed capsules. They also trialled new bottle belts made from recycled plastic, so 700 runners could carry water bottles with them during their run.

Meanwhile, some people still think running a marathon could be our best foot forward in helping the planet. Dr Andrea Collins from Cardiff University told the BBC: “Training for a marathon makes you more sustainable in day-to-day activities. I started walking or running to work every day. Being environmentally friendly while training kind of sticks with you and becomes a way of life.”

So while you may not be the top runner in a marathon, let’s hope the event, in terms of sustainability, certainly is!
