Denmark wants to make all domestic flights fossil fuel-free by 2030. Prime Minister Mette Frederiksen announced the goal in a New Year speech. Denmark【小题1】     (be) known for its green qualification. It is famous as a heaven for cyclists and a huge destination for eco-minded food experts, and now it even has【小题2】   waste-to-energy plant complete with its own ski spot.

Most impressively of all, though, the country aims to reduce its carbon emissions【小题3】   70 percent by 2030. In the speech,Prime Minister Mette Frederiksen said such changes were necessary 【小题4】 “to travel is to live and therefore we fly”. Researchers are already working on【小题5】     (find) alternative fuels for those flights, and hydrogen(氢) is the 【小题6】(likely) competitor.

【小题7】(fortunate), the Scandinavian country isn’t the only nation trying to make flying a greener travel option. By 2030, Sweden wants all airlines to have switched to bio-fuels. To make this happen, they【小题8】(tax) on the emissions of their fossil fuel-powered flights soon. In   France, meanwhile, flights which could be replaced by a train trip that takes under two and a half hours are likely【小题9】(ban). That’s all great news,and hopefully a sign of even greater things to come. Could a big【小题10】(play) like the USA or China be next?

A drop in tourism during the coronavirus crisis is making it more difficult for some organizations to protect 【小题1】 (threaten) wildlife in Africa. Wildlife 【小题2】 (official) fear poaching (偷猎) activity will rise because the collapse of the travel industry leaves less money for guarding animals.

African rhinos have long been 【小题3】 threat from poachers who kill them for their horns. The illegal trade is fueled by the belief, in some cultures, 【小题4】 the horns have medicinal value which has not been proven by science.

The number of black rhinos in Africa 【小题5】 (increase) slowly. But a report in March by the International Union for Conservation of Nature (IUCN) said it still considered the animals “critically endangered”. In part, it credits the comeback of the rhinos to effective law enforcement. 【小题6】, the enforcement measures are very

The IUCN expects to lose $3 to $ 4 million this year and the 【小题7】 (lose) severely limits the group’s ability 【小题8】 (protect) the rhinos. Wildlife activists across Africa are now waiting to see how poachers will react to the current situation, and whether more rare wildlife 【小题9】 (kill).

The IUCN said the population of black rhinos grew at a 【小题10】 (year) rate of 2.5 percent between 2012 and 2018. Now, there are more than 5,600 animals. That growth was predicted to continue over the next five years, the environmental group said.

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 【小题1】 (warm) climate and frequent spring rainfall at that time.

China set March 12 【小题2】 the National Tree-Planting Day in 1979 to memorize Sun Yat-sen (孙中山), 【小题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 【小题4】 (stick) to the tradition of planting trees in spring. “Students should establish an awareness of protecting 【小题5】 environment and cherish the green plants,” Xi said in 2017 when 【小题6】 (attend) a tree planting activity in Chaoyang district of Beijing.

China has seen a remarkable 【小题7】 (grow) in forest resources and afforestation(造林) projects. Nationwide voluntary tree planting campaigns in China over the past four decades 【小题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 【小题9】 (plant) forests.

In the future, China will launch more effective 【小题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.
