Unit 3 Book 3 Environmental Protection -Reading and ThinkingCLIMATE CHANGE REQUIRES THE WORLD'S ATTENTIONWe _1_(know) about climate change for decades. There islittle doubt that Earth is getting warmer and warmer (see the graph). A warmingocean and atmosphere along with _2_(melt) ice and rising sea levelsprovide evidence of a dramatic change in the global climate.In 2013, a lot of people were shocked by _3_ news photo of a deadpolar bear that was found on Norway's Arctic island of Svalbard. According tothe scientists who found its dead body, all that remained _4_ the polarbear was "skin and bones". An expert who _5_(study) polar bears formany years said that from the position of its dead body, the bear appeared_6_(starve) and died. Experts claimed that low sea-ice levelscaused by climate change meant the bear could not hunt seals as before, so it hadto travel greater distances in order to find food. This _7_(alarm)case showed how the increase in temperature had an impact _8_ Earth'secology.Then what is causing the increase in the _9_(globe) averagesurface temperature? Climate scientists often mention a key climate process_10_(call) the "greenhouse effect", _11_ has twocommon meanings: the "natural" greenhouse effect and the "man-made"greenhouse effect. The "natural" greenhouse effect refers to the tact that heatfrom the sun enters the atmosphere and warms Earths surface as short-waveradiation. The heat _12_(release) back into space at longer wavelengths. Greenhouse gases in the atmosphere, such as methane and carbondioxide, trap some of the heat, _13_(keep) Earth s climate warmandhabitable.Withoutthisprocess,Earthcouldnotsustainlife._14_, the "man-made greenhouse effect has now become a bigproblem. When people produce huge amounts of extra greenhouse gases byburning fossil fuels, more heat energy _15_(trap) in the1 / 4atmosphere and causes Earth's surface temperature to rise quickly.There is strong and comprehensive evidence _16_ the rise intemperature has led to an increase in extreme weather and natural disastersworldwide, not only causing serious damage, but also costing human lives.Climate scientists have warned that _17_ we do not take appropriateactions, this warming trend will _18_(probable) continue andthere will be a higher price to pay. In fact, news reports are frequently broadcastaboutextremerainstormsandheatwavescausingdeathsand_19_(economy) losses._20_(continue)greenhousegasemissionswillresult_21_ further warming and long-lasting changes to the global climate. Thisrequires the attention of people all over the world. Governments need to considermakingpoliciesandtakingappropriateactionsandmeasures_22_(reduce) greenhouse gas emissions. We as individuals can alsoreduce our "carbon footprint" by restricting the amount of carbon dioxide ourlifestyles produce. It is our responsibility to seize every opportunity_23_(educate) everyone about global warming, along with itscausesandimpacts,becausethisisthemostseriousissue_24_(affect) all of us on this planet. _25_ what will you doto help?REDUCING WATER POLLUTION IN THE LI RIVERThe beautiful Li River and its _1_(amaze) surroundingscenery is one of the most well-known tourist _2_(destination)in China's Guangxi Zhuang Autonomous Region. It attracts millions of domesticand foreign visitors each year. _3_, its reputation as a topdestination has had negative effects _4_ the river's water quality. Thisreport looks at the problem of water pollution and some actions that_5_(take) to deal with it.2 / 4_6_(previous), water quality in the Li River had sufferedgreatly from an _7_(increase) volume of tourists, many of_8_ frequently threw garbage into the river. Many tour boatscontributed _9_ the problem too. Kitchens on board were using lotsof oil, which was often thrown into the water. The growth in tourism also_10_(mean) the local population rose rapidly, as well as thenumber of commercial and industrial enterprises. Water pollution levelsincreased,withmorehouseholdandcommercialwaste_11_(end) up in the river. In order to feed more people, morechemicals were used to increase crop production. These chemicals led to severewater quality issues, _12_(cause) a decrease in the number offishspecies.Localofficialswereconcernedthatthepollution_13_(damage) the natural environment and felt that urgentsteps should be taken to restore the river's original beauty.A comprehensive initiative was started, with a number of measures that_14_(address) the issues. The construction of waste watertreatment facilities improved the water quality and water conservation. Thecollectionandtransportofhouseholdwastewasalsoimproved._15_(dozen) of polluting enterprises were closed or moved.The local government set up strict regulations _16_(regard)further industrial development. New rules were also introduced regarding tourboat routes and garbage _17_(dispose) methods. Furthermore,the local authorities began to use the media to spread environmental awarenessand encourage _18_(great) use of clean energy. At the sametime, they started to carry out inspections regularly and fine tourist organisations_19_ abuses. With these measures, it is believed that the beauty ofthe Li River _20_(preserve) for generations to come.In addition, the ambitious "Water Ten Plan" is also now tackling waterpollution across the country. Other initiatives, such as the "River Chief System",3 / 4hold senior officials _21_(response) for reducing waterpollution. _22_ such campaigns in effect, China's waterways areheading towards a clean and sustainable future.4 / 4
