[ti:Scientists Warn of More Deadly Pandemics if Nature Not Protected] [by:www.houshang36.top] [00:00.00]更多听力请访问51VOA.COM [00:00.04]Scientific experts have warned that deadly pandemics [00:05.20]are likely to keep happening if action is not taken [00:10.76]to protect natural environments. [00:15.60]Future pandemics will happen more often, spread faster [00:21.60]and kill more people than COVID-19, the experts said. [00:28.44]Such events are also expected [00:32.12]to cause lasting harm to the world economy. [00:37.20]The warning came in a report from the Intergovernmental [00:42.84]Science-Policy Platform on Biodiversity and Ecosystem Services, [00:50.56]an international expert group that advises governments. [00:56.08]The group has more than 130 member states. [01:02.16]The experts called for major efforts aimed at preventing pandemics [01:09.88]rather than trying to contain them after they happen. [01:14.44]The report urges major worldwide efforts to stop habitat destruction [01:22.16]that can lead viruses to jump from wild animals to humans. [01:29.44]The Centers for Disease Control and Prevention [01:34.04]has estimated that three out of every four [01:38.36]new or emerging infectious diseases [01:41.96]in people come from animals. [01:45.80]Scientists have said COVID-19 probably started in bats [01:52.20]and began spreading among humans. [01:55.52]In their report, the experts predict that about half of an estimated [02:01.80]1.7 million undiscovered viruses in nature [02:07.24]might be able to infect people. [02:10.24]Activities such as poaching or clearing forests to grow soy [02:16.96]or palm oil can bring humans and disease closer together. [02:23.96]Deforestation, agriculture expansion, urbanization [02:29.88]and other land-use changes are responsible [02:34.52]for about one-third of all new diseases [02:38.52]that have emerged since 1960, the report says. [02:45.04]The $100 billion global wildlife trade [02:50.20]is also responsible for the spread of new and existing diseases. [02:57.36]The experts predict that about $50 billion a year [03:02.84]in pandemic prevention spending could save the world [03:08.04]about $1 trillion a year, on average, in economic damage. [03:15.92]They said that as of July, the economic cost [03:20.56]from COVID-19 was at least $8 trillion and rising. [03:27.44]Peter Daszak was the report's lead writer. [03:32.44]He is president of EcoHealth Alliance, [03:37.20]an international health, environment and development organization. [03:43.92]He said in a statement that even though the experts call for urgent action, [03:50.92]"this is not a doom and gloom report [03:54.64]saying the world's going to end and it's too late." [03:59.08]Instead, Daszak said it should be seen as "an optimistic call for action." [04:08.40]He noted that the current method for dealing with pandemics [04:13.68]is to wait for them to emerge and then try to identify them before they spread. [04:21.36]COVID-19 has demonstrated the problems with that plan. [04:28.44]Officials attempted to contain COVID-19 [04:32.76]after the disease was discovered last year, but it was already too late. [04:40.52]"And here we are waiting for a vaccine and drugs to work," Daszak said. [04:48.68]"It's not a good strategy. We need to do more." [04:54.32]I'm Bryan Lynn.
