《Wildlife Protection》Section A PPT
Many animal and plant species have become extinct and many more are in critical danger.
The dodo is a classic example of how humans caused damage to the earth’s 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.
The 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 decreased① in the last 50 years,and the animals remain under constant threat from poachers(偷猎者).
The International Whaling Commission is fighting to ensure② the survival of the whale species.Despite the fact that one-third of the world’s oceans have been declared whale sanctuaries (保护区),7 out of 13 whale species remain endangered.Collisions (碰撞) with ships,poisonous pollution③ and being caught in fishing nets are some major causes of whale deaths.
The 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 disappearing④,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.
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.
