hat causes“black pollution”?S c rip tEvery day,the average person breathes in about 20,000 lite rs of air.Everytime w e breathe,w e risk inhaling dangerous chemicals that have found th eirway into the air.Air pollution includes a ll pollutants found in the atmosphere.Thesedangerous substances can be either in the form of gases or particles.Air pollution can be found both outdoors and indoors.Pollutants can betrapped inside buildings,causing indoor pollution that lasts for a longtime.The sources of a ir pollution are both natural and human-based.A s one mightexpect,humans have been producing increasing amounts of pollution as timehas progressed,and they now account for the majority of pollutants releasedinto the air.Air pollution has been a problem throughout history.Even in Ancient R om epeople complained about smoke put into the atmosphere.The effects of a ir pollution are diverse and numerous.Air pollution canhave serious consequences for the health of human beings,and severelyaffects the natural ecosystem.Because i t is located in the atmosphere,a ir pollution is able to traveleasily.A s a result,a ir pollution is a global problem and has been thesubject of global cooperation and conflict.Som e areas now suffer more than others from a ir pollution.C ities with largenumbers of automobiles or those that use great quantities of coal oftensuffer most severely from a ir pollution problems.S c rip tThe panda is found only in the western mountains of China.It is one of themost popular animals in the world.Although it is protected by the Chinesegovernment by s tric t laws,it is s t i l l in serious danger of extinction.Experts guess that there are altogether fewer than 1,000 giant pandas le ftin China.The pandas live in bamboo forests in the high mountains.Theirnumbers fe ll dramatically e arlier th is century when large areas of bambooforest were cut dow n and turned over to agriculture.To deal with the c risis,experts suggested that special reserves be set upin the remaining forest to protect the pandas.Also,pandas were taken into zoos to begin a breeding program and the pandasbred there could one day be returned to the wild.Since the panda is anational symbol in China,the program received a lot of attention.However,the panda is a very solitary creature,and the number of pandas in the wildcontinues to drop.For years,zoos have spent millions of dollars to placepandas together in breeding pairs.Almost a ll of these actions have endedin failure.A s a result,experts predict that pandas w ill be extinct within40 to 100 years unless drastic measures are taken.Because of the strangely so litary nature of the giant panda,the debate aboutthe use of cloning in conservation has emerged in China.Today mankind faces the loss of one endangered species after another throughthe destruction of the environment.People cannot afford to lose the panda,which is found nowhere outside China.
