A

Many animal and plant species have become extinct(灭绝的)and many more are in critical danger. Finding ways to protect the earth's wildlife and conserve(保护)the natural world they inhabit(居住)is now more important than ever.

Dodo

The Dodo is a classic example of how human caused damage to the earth's biology. The flightless Dodo was native to the Island of Mauritius in the Indian Ocean. It lived off fruit fallen from the island's trees and lived unthreatened until humans arrived in 1505. 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 last one was killed in 1681.

Rhinos

The Rhino (犀牛) horn is a highly priced 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(保护区). Their numbers have rapidly decreased in the last 50 years, and the animals remain under constant threat from poachers(偷猎者) .

The Giant Panda

The future of the World Wildlife Fund's symbol is far from certain. As few as 1000 remain in the wild. The Chinese government has set up 33 panda reserves to protect these beautiful animals and mad e poaching them punishable with 20 years in prison. However, The panda's distinct black and white patched coat fetches a high price on the black market and determined poachers still pose(造成)one of the most serious threats to the animals continued existence.
