Scientists say that as temperatures go up in the polar areas.invading( plants and insects,including the flies,cause a major threat. More and more of these invaders,in the form of larvae or seeds,are surviving in coastal areas around the South Pole,where the temperature has risen by almost 3C over the past five decades.Glaciers have melted,exposing more land which has been occupied by mosses that have been found to be growing more quickly and thickly than ever before -providing potential green homes for invaders. "The common houseflies are a perfect example of the problem the Antarctic now faces from invading species,"said Dominic Hodgson of the British Antarctic Survey."They arrive by ship,where they exist in kitchens.They now have an increasing chance of surviving in the Antarctic as it warms up,and that is a worry.Insects like the houseflies carry bacteria that could have a deadly effect on native life forms." The Antarctic has several native species of insects.Together with its native mosses,these are now under increased threat from three major sources:visiting scientists,increasing number of tourists and global warming.However,it is global warming that is the main driver of the "greening"of the Antarctic. In the 2015-2016 travel season,more than 38,000 tourists visited the Antarctic."These tourists are often very careful about not leaving waste.But they could carry seeds or larvae on their boots when they set foot on the Antarctic. said Dominic. More and more invading insects and plants have been found on the Antarctic and have required removal."The insects and plants that are native to the Antarctic have survived there for thousands of years.said Dominic."We have to act now if we want to save the environment" 黄牌图邛些 1.What does the underlined word "mosses"in Paragraph 3 refer to?
