Source 8

1. http://www.businessweek.com/bwdaily/dnflash/nov2005/nf20051128_4335_db039.htm
2. The source is Business week by Dexter Roberts.
3. Dexter Roberts credentials are a reporter that reports on environmental issues.
4. What the source says is as the recent benzene spill shows, worsening pollution increasingly endangers Chinese citizens, and their spreading anger is worrying Beijing. It also says that people are suffering respiratory sickness from the smog and extinction of animals and wildlife such as bears has occurred as a result of the pollution.
5. Yes, I believe the source.
6. I believe the source because it is a Business Week newspaper or report and this is a news analysis of what is happening in china. It also seems very logical that pollution can cause these things to wildlife and people after long term effects.
