[ti:Dutch Inventor Demonstrates Device to Remove Plastic from Rivers] [by:www.otzgay.live] [00:00.00]更多聽力請訪問51VOA.COM [00:00.04]A young Dutch inventor is widening his effort to clean up floating plastic from the Pacific Ocean. [00:11.00]He has developed a floating device to trap plastic waste [00:16.80]moving into rivers before it reaches the high seas. [00:22.68]Boyan Slat was just 18 years old when he invented a system for catching waste in the ocean. [00:32.32]He also founded an environmental group called The Ocean Cleanup. [00:39.08]Its purpose is to develop and deploy the system. [00:44.96]Last Saturday, the 25-year-old Slat announced the next step in his fight: [00:53.36]a floating device that he calls the "Interceptor." [00:58.64]It removes plastic out of rivers. [01:02.12]The device is powered by energy from the sun. [01:07.56]"We need to close the tap, which means preventing more plastic [01:12.86]from reaching the ocean in the first place," Slat said. [01:18.16]He added that rivers are "the arteries that carry the trash from land to sea." [01:26.56]The Ocean Cleanup has been criticized in the past for directing its attention [01:32.94]only on plastic waste already in the world's oceans. [01:38.96]Experts say 8 million metric tons of waste flow into the ocean each year [01:46.11]from rivers, creeks and seaside areas. [01:51.56]The plastic endangers fish and other sea creatures. [01:57.80]Three of the machines have already been deployed to Indonesia, Malaysia and Vietnam. [02:05.53]Slat said a fourth is going to the Dominican Republic. [02:11.80]Izham Hashim, a Malaysian government official, was present at the Interceptor's launch in his country. [02:21.64]Hashim told The Associated Press (AP) that he was happy with the machine. [02:27.34]"It has been used for 1 1/2 months in the river and it's doing very well, [02:34.23]collecting the plastic bottles and all the rubbish," he said. [02:40.16]Slat said he believes 1,000 rivers are responsible [02:45.15]for about 80% of plastic going into the world's oceans. [02:51.12]He said he wants to try to clean them all in the next five years. [02:58.04]He added, "This is not going to be easy, but imagine if we do get this done. [03:05.05]We could truly make our oceans clean again." [03:10.20]Slat used his announcement to ask for support from countries interested in cleaning up their rivers. [03:19.20]He also wants support from businesses prepared to offer financial support [03:24.89]and help with the operation of the devices. [03:30.20]The Interceptor is designed to be secured in rivers. [03:34.57]Its nose is shaped to deflect away larger floating objects like tree trunks. [03:42.76]The interceptors work by guiding plastic waste into an opening in the front of the devices. [03:51.04]The waste is then carried inside the machine where it is dropped into containers. [03:58.40]The interceptor sends a text message to local operators that can come and empty it when it is full. [04:08.04]Slat demonstrated how it worked by putting hundreds of yellow rubber ducks [04:13.60]into the water at the launch event in the Dutch city of Rotterdam. [04:19.68]The interceptor caught nearly all of them. [04:23.48]Each machine currently costs about $775,600. [04:32.76]Slat said the cost will likely drop as production increases. [04:39.36]Jan van Franeker is with the Wageningen Marine Research institute. [04:45.92]He has been critical of The Ocean Cleanup in the past, but said the new device looks promising. [04:55.04]He told the AP, "I am really happy they finally moved toward the source of the litter. [05:02.44]The design, from what I can see, looks pretty good." [05:07.60]Slat argued that the economic effect of not removing plastic from rivers [05:13.63]is higher than the cost of buying and using the machines. [05:19.68]"Deploying interceptors is even cheaper than deploying nothing at all," he noted. [05:26.88]I'm Caty Weaver. [05:28.33]更多聽力請訪問51VOA.COM 宁夏11选5推荐号码
