1 . Scientists say a huge percentage of bird species are in danger because their habitats, or homelands, are disappearing.
Traditional migration (迁徙) paths take birds through countries that are not protecting the places for birds to stop, rest and feed. The scientists studied the migration or flight paths of almost 1,500 species. They decided that 91 percent of them passed through dangerous areas.
The major danger for migratory birds is development. Buildings and pavements have covered the places where birds stop and feed as they move from one part of the world to another. One of the scientists who worked on the study says “Many of these important places have been lost to land reclamation because of urban, industrial and agricultural land expansion”.
The problem, according to scientists, is that many of these small birds die along their migration paths because they don’t have a safe place to feed and rest. There is no place to restore (恢复) their energy for the next part of their journey. Countries in North Africa, Central Asia and those along the coasts of East Asia are having the most difficult time in protecting land. The scientists say these countries do not have enough areas that are safe for birds. One species that doesn’t exist now is the Eskimo curlew. “Our world gets poorer every time we lose a species,” one of the scientists says.
The researchers say countries need to work together and come up with safe stopping areas for birds that pass through their boundaries. For example, one country might have preserved safe zones for migrating birds. But a neighbor country might not. A bird might die.
One scientist who is not connected with the report tells Los Angeles Times that while some habitats are changing, more work can be done to make urban areas safe for birds.
He says small changes, like planting more native plants or keeping cats out of the areas birds would be likely to use, could make a big difference.

Yesterday, I took a walk in the Panzhihua Park with my parents. The beautiful flowers were in various color. We were enjoying the scenery around when something unpleasant catch my attention. Not far from us, the middle-aged woman was eating some oranges while chat with her friends. In my surprise, she threw the orange skin on the ground, totally ignoring the sign nearby which was read “No Littering”. I think it is not a good behavior throw rubbish somewhere, and all of us should love our environment. As visitors, you should do something to protect the park after it becomes a huge dustbin.
