[00:00.04]Scientists in Ireland are collecting native seaweed
[00:05.60]to feed to cows and sheep to reduce the methane gas
[00:11.56]that the farm animals release.
[00:14.72]Research has shown that seaweed fed to animals
[00:19.56]can cut the amount of the climate-warming gas they produce.
[00:25.04]Ireland has Europe's highest per capita output of methane gas.
[00:32.84]At the recent United Nations Climate Change conference in Scotland,
[00:38.84]Ireland joined a worldwide goal
[00:42.40]to cut output of methane gas by 30 percent by 2030.
[00:49.00]Irish officials have said such reductions
[00:53.96]will mostly be reached through a 50 percent cut
[00:58.60]in non-agriculture methane.
[01:01.68]The country expects to reduce farm-related methane
[01:06.76]by 10 percent by 2030.
[01:10.40]The program aims to use seaweed additives in food
[01:15.96]to avoid having to reduce animal numbers
[01:20.20]to reach goals related to efforts against climate change.
[01:26.16]About 20 different kinds of seaweed,
[01:30.00]most from Ireland's Atlantic coast,
[01:33.56]have been tested by researchers.
[01:37.64]Many other kinds have been collected
[01:40.80]by the project's partners in Norway,
[01:44.24]Canada, Sweden, Germany and Britain.
[01:49.20]American and Australian scientists
[01:52.96]have already demonstrated the methane-reducing qualities
[01:58.16]of one seaweed, called Asparagopsis.
[02:02.44]Small amounts were added to animal feed in tests.
[02:07.64]But this kind of seaweed is not easy to grow
[02:11.88]in Northwestern Europe.
[02:14.76]The Irish project aims to find native seaweeds
[02:19.28]within the country instead.
[02:21.96]But some researchers admit the local versions
[02:26.60]are not likely to reach the reduction in methane levels
[02:31.32]of over 80 percent shown with Asparagopsis.
[02:36.24]"We have identified some brown seaweeds
[02:40.28]that are very positive and they're producing results,"
[02:44.88]Maria Hayes told Reuters news agency.
[02:49.28]She is the project leader for the SeaSolutions project.
[02:54.92]The project team has reported methane reductions
[02:59.88]of between 11 and 20 percent in early tests.
[03:05.12]Irish researchers are working on ways
[03:09.72]to bring the seaweed additives
[03:12.16]into the nation's farming system for cattle.
[03:16.12]Most cattle are mainly fed grass.
[03:20.44]On one farm southwest of Belfast,
[03:24.36]treats are used to persuade cows to put their heads
[03:28.96]into a solar-powered machine
[03:31.44]that measures the level of methane on their breath.
[03:35.84]This same method will be used
[03:39.12]to test animals that have been fed seaweed additives.
[03:44.04]Dutch chemical company Royal DSM
[03:48.24]produces a food additive that it says
[03:52.16]can cut methane release by about 30 percent.
[03:56.88]The company said it had received government approval
[04:01.32]in Brazil and Chile
[04:03.88]and is currently seeking approval in the European Union.
[04:08.64]Not everyone is sure that such additives
[04:13.28]can help meet the latest climate change targets.
[04:18.04]Sadhbh O'Neill is a climate policy
[04:21.68]and environmental politics expert at Dublin City University.
[04:28.36]She has been critical of industry attempts
[04:32.40]to depend on technology rather than to seek workable
[04:37.64]long-term goals for Ireland's agriculture industry.
[04:42.44]"Scaling up these solutions takes time.
[04:47.40]We don't have time," O'Neill said.
[04:51.12]Jenny O'Halloran harvests seaweed by hand
[04:56.00]on Inis Mór island, off Ireland's west coast.
[05:00.88]She told Reuters she thinks
[05:03.92]interest in the industry will keep growing.
[05:08.08]"Maybe the future...is actually farming seaweed,
[05:13.20]which I think has to be part of the conversation
[05:17.40]when it comes to the future of seaweed in Ireland."

END OF TRACK. "END OF TRACK." The two men bowed. "Whoever was that person you were talking to?" she enquired, as soon as they stood together. The took of triumph faded from her eyes, she had grown worn and weary. The roses were wilting on the walls, the lights were mostly down now. Hetty, looking in to see if anything was wanted, found herself driven away almost fiercely. I only saw Master Jervie once when he called at tea time, The year 1747 was opened by measures of restriction. The House of Lords, offended at the publication of the proceedings of the trial of Lord Lovat, summoned the parties to their bar, committed them to prison, and refused to liberate them till they had pledged themselves not to repeat the offence, and had paid very heavy fees. The consequence of this was that the transactions of the Peers were almost entirely suppressed for nearly thirty years from this time, and we draw our knowledge of them chiefly from notes taken by Horace Walpole and Lord Chancellor Hardwicke. What is still more remarkable, the reports of the House of Commons, being taken by stealth, and on the merest sufferance, are of the most meagre kind, sometimes altogether wanting, and the speeches are given uniformly under fictitious names; for to have attributed to Pitt or Pelham their[112] speeches by name would have brought down on the printers the summary vengeance of the House. Many of the members complained bitterly of this breach of the privileges of Parliament, and of "being put into print by low fellows"; but Pelham had the sense to tolerate them, saying, "Let them alone; they make better speeches for us than we can make for ourselves." Altogether, the House of Commons exhibited the most deplorable aspect that can be conceived. The Ministry had pursued Walpole's system of buying up opponents by place, or pension, or secret service money, till there was no life left in the House. Ministers passed their measures without troubling themselves to say much in their behalf; and the opposition dwindled to Sir John Hinde Cotton, now dismissed from office, and a feeble remnant of Jacobites raised but miserable resistance. In vain the Prince of Wales and the secret instigations of Bolingbroke and Doddington stimulated the spirit of discontent; both Houses had degenerated into most silent and insignificant arenas of very commonplace business. "It certainly will be. Miss Widgeon," answered Maria, with strictly "company manners." "One who has never had a brother exposed to the constant dangers of army life can hardly understand how glad we all feel to have Si snatched from the very jaws of death and brung back to us." "Just plug at 'em as you would at a crow, and then go on your way whistlin'?" persisted Harry. "Hurroo!" echoed Hennessey; "that's the ticket." "Come forward, keeper," continued the baron, "and state how these arrows came into your hands!" "Yes." HoMEJULIA京香2018下载
