are in critical danger.DodoThe dodo is a classic example of how humans caused damage to the earths biology.The flightless dodo was native to the Island of Mauritius in the Indian Ocean.The easily controlled bird became a source of food for sailors and was attacked by animals introduced to the island by humans such as pigs,monkeys and rats.The population of dodos rapidly decreased and the last one was killed in 1681.第2页晨读晚诵RhinosThe rhino horn is a highly prized item for Asian medicine.This has led to the animal being hunted in its natural habitat.Once widespread in Africa and Eurasia,most rhinos now live in protected natural parks and reserves.Their numbers have rapidly decreased in the last 50 years,and the animals remain under constant threat from poachers(偷猎者).第3页晨读晚诵WhalesThe International Whaling Commission is fighting to ensure the survival of the whale species.Despite the fact that one-third of the worlds oceans have been declared whale sanctuaries(保护区),7 out of 13 whale species remain endangered.Collisions(碰撞)with ships,poisonous pollution and being caught in fishing nets are some major causes of whale deaths.第4页晨读晚诵TigersThe last 100 years has seen a 95%reduction in the numbers of remaining tigers to between 5,000 and 7,000 and the Bali,Javan,and Caspian tigers are already extinct.The South China tiger is precariously(危险地)close to disappearing,with only 20 to 30 still alive.Like the rhino horn,tigers bones and organs are sought after for medicines.These items are traded illegally along with tiger skins.第5页晨读晚诵词海拾贝词海拾贝decrease
