2 . While pedaling hard on a bike, do you feel like you are saving the planet? Or do you just feel out of breath? In fact, cycling is now considered one of the ultimate weapons humanity can use in the fight against climate change.

The United Nations General Assembly passed a resolution in March supporting bicycles as a tool for dealing with climate change. The resolution calls on member states to “integrate the bicycle into public transportation, in urban and rural settings in developing and developed countries”, with all 193 members of the UN unanimously (一致同意地) adopting the resolution.

This decision has received a positive response from numerous groups in support of cycling and environmental awareness internationally. “It is an important step toward the recognition of cycling as an important mode of transport,” said the European Cyclists’ Federation.

The resolution from the UN comes at a time when climate change has returned to the center of global attention. On Feb 28, the UN published a new report assessing recent climate change trends. The report warns that the global average temperature will rise by 1.5 C above pre-industrial levels (1850-1900), with more than 40 percent of the world’s population being “highly vulnerable” to these temperature changes.

In May 2020, bike sales in Spain increased 22-fold (22倍) compared with 2019. In London, large parts of the city are being closed off to cars so that people can walk and cycle safely. Cities like Berlin and Montreal have also added new, wider bike lanes.

More importantly, the resolution focuses on bike-sharing services, which could be seen as recognition of China’s bike-sharing success, noted CGTN.

China has some of the largest bike-sharing systems in the world. The country has more than 360 cities with dockless (无桩的) bike-sharing systems, with nearly 20 million bicycles for an average 47 million trips each day, according to China’s Ministry of Transport. This transportation option that produces zero emissions reduces the amount of CO2 released into the atmosphere by 4.8 million tons every year, according to a 2020 report from the World Resources Institute.

In China, Tree Planting Day falls on March 12, but more often people plant trees during Qing Ming Festival in early April. Newly-planted trees can survive more easily with a     1     (warm) climate and frequent spring rainfall at that time.

China set March 12     2     the National Tree-Planting Day in 1979 to memorize Sun Yat-sen (孙中山),     3     died on March 12, 1925. Sun had called for planting trees.

Since 2013, President Xi Jinping has joined Beijing citizens in tree planting activities for nine years in a row. President Xi called on the public     4     (stick) to the tradition of planting trees in spring. “Students should establish an awareness of protecting     5     environment and cherish the green plants,” Xi said in 2017 when     6     (attend) a tree planting activity in Chaoyang district of Beijing.

China has seen a remarkable     7     (grow) in forest resources and afforestation(造林) projects. Nationwide voluntary tree planting campaigns in China over the past four decades     8     (see) increased participation by members of the public and nearly 79 billion trees have been planted. The campaign has made China the country with the largest increase in forest resources and the largest area of     9     (plant) forests.

In the future, China will launch more effective     10     (measure) to fulfill the country’s climate commitment to peak (达到峰值) carbon dioxide emissions before 2030 and achieve carbon neutrality (碳中和) before 2060.

5 . Japanese researchers placed electronic devices(装置)on seals(海豹)in Antarctic waters to collect surprising information about the environment there. Japan’s National Institute of Polar Research started the research project in 2017. The team recently reported its results in a study in the publication Limnology and Oceanography.

Eight Weddell seals were fitted with the devices,which have antennas(天线)to send electronic signals.The 580-gram monitoring devices were attached(缚上;系上)to the animals’heads. They were designed to measure data such as water temperatures and sea salt levels.

Investigative teams on ships have difficulty reaching important research areas in Antarctica. These include areas along continental shelf formations where ice is attached to the shore, the National Institute of Polar Research said in a statement. Nobuo Kokubun led the project. Since the seals are active year-round, Kokubun added, “I thought we should have them collect the data.”

He told Reuters that the research also helps scientists follow the seals’ behaviors and learn about their relationship to the environment. “During the summer, we can go to Antarctica on icebreakers to conduct actual research activities, so that we can collect data there.” Kokubun said. ”But during the winter. such things cannot be done in so many places.“

Information gathered from the seals showed that one of the animals traveled as far as 633kilometers from Japan’s Showa Station in Antarctica. Another dove to a depth of 700 meters.Kokubun said the scientists learned from the data that warm seawater from the upper levels of the open sea reached Antarctica from March through the winter of 2017. The water flowed below the ice, bringing in sea creatures like Antarctic krill, an important food for seals.

Kokubun and his team plan to keep finding new ways to further examine the effects of climate change on Antarctic coastal areas. Next, he hopes to make the device small enough to fit on other animals at the South Pole, such as penguins,“The advantage with penguins is that they come back to the same place and we can collect data from them immediately,”Kokubun said.

8 . Zhang Fan, 36, a movie visual effects designer who returned to Beijing from New Zealand for work last year, was surprised by the improvement to the city’s air quality. “I remember the smell in the air and the frequent smoggy days before I left in 2013, after getting a job offer from a film company in New Zealand, ” he said. Last year, a Chinese company offered Zhang a more promising position, so he returned, saying that he could find more opportunities in his line of work in Beijing than elsewhere. In addition to rapid economic development in the Chinese capital, he said the most impressive change is the local air quality. “People discussed air pollution a lot when I was in Beijing previously. Now, it seems that the topic has disappeared completely, as every day is good in terms of air quality,” Zhang said. “The sky in Beijing these days is so clear. ”

On Jan. 4, the municipal authorities in Beijing announced a comprehensive success in improving air quality, with the city’s annual average concentration of PM2. 5 in the air, falling to 33 micrograms per cubic meter, and ozone (臭氧) concentration dropping to 149 mcg per cu m last year.

Yu Jianhua, spokesman for the Beijing Municipal Ecology and Environment Bureau, said at a news conference, “This is a milestone for Beijing’s hard work in fighting air pollution and also means that the city has met its air quality target outlined in the 14th Five-Year Plan(2021-25) ahead of schedule. Beijing has demonstrated to the world over the past 20 years that a mega city with a rapidly increasing GDP, vehicle count, population and energy consumption can move forward to cut air pollution effectively. The PM2.5 reduction over the past few years has surpassed that of developed countries during the same period.

According to the Bureau, the city’s average concentration of PM2.5 dropped by 63 percent last year from 2013, an average annual reduction of about 8 percent. The city experienced 288 days of good air quality last year—up from 112 days in 2013—and just eight days of heavy air pollution. This achievement is clear to see and exciting, but it has not been easy work.
