:00:00. > :00:07.Hello there, hope you're having a lovely Monday. Ricky here with the
:00:08. > :00:10.best stories of the day. On the way... How masses of supermarket
:00:11. > :00:12.food is never eaten and ends up in the bin. And... A blanket of smog
:00:13. > :00:22.almost shuts down a Chinese city. First to a warning that many of you
:00:23. > :00:24.are taking too many risks online. A new survey suggests that children
:00:25. > :00:28.are sharing too much personal information on the Web. Experts now
:00:29. > :00:31.say parents should get more invlved with the technology you guys are
:00:32. > :00:36.using to help keep you safe. Here's Martin.
:00:37. > :00:42.How do you know who you're talking to online is really who they say
:00:43. > :00:47.they are? You're always being told never to meet up with a stranger in
:00:48. > :00:50.the street, but a survey of 0- to to 11-year-olds suggests some of you
:00:51. > :01:02.are doing just that via the internet. Campaigns like this one
:01:03. > :01:07.are designed to show children the dangers of chatting to people they
:01:08. > :01:11.don't know online. But the charity Safe and Secure Online say that too
:01:12. > :01:14.many kids are taking too many risks and using the internet late into the
:01:15. > :01:18.night. It surveyed more than 1, 00 children. 18% - that's nearly one in
:01:19. > :01:19.five - said they had met, in real life, friends they had previously
:01:20. > :01:22.only known online. night. It surveyed more than 1, 00
:01:23. > :01:27.children. 22% had been online after 9pm on a school night. And 12% had
:01:28. > :01:33.missed school after a late night on the internet. Youngsters actually
:01:34. > :01:36.participate in a lot of risky behaviours that I don't believe the
:01:37. > :01:40.parents know about. Not because of any ill will on behalf of the
:01:41. > :01:43.parents, it's just that the parents do not understand the technology.
:01:44. > :01:51.This primary school in Kent is taking part in a special class about
:01:52. > :01:56.the dangers of the internet. I spoke to kids in Salford. I have got a
:01:57. > :02:03.friend who is on Facebook. Someone said, can you meet me in some place?
:02:04. > :02:06.My sister had to delete her account because somebody was texting her
:02:07. > :02:13.that she did not know. My mum always says, anything could happen. You can
:02:14. > :02:19.find out more about how to stay safe online on the Newsround website
:02:20. > :02:23.Next to Australia, where it is feared huge bush fires in New South
:02:24. > :02:25.Wales could merge to form a massive wildfire covering hundreds of
:02:26. > :02:29.kilometres. Hundreds have been forced to leave their homes as a
:02:30. > :02:32.state of emergency is declared. I've been keeping across the latest on
:02:33. > :02:34.this today. New South Wales, Australia. Firefighters are battling
:02:35. > :02:36.more than 56 separate blazes spreading across hundreds of
:02:37. > :02:40.kilometres. The huge wildfires that started this weekend are being
:02:41. > :02:44.described as some of the most destructive ever to hit the state.
:02:45. > :02:48.Australia is no stranger to wildfires. As we head into winter,
:02:49. > :02:52.Down Under, Australians are gearing up for summer. And as the
:02:53. > :02:57.temperatures rise between December and February, the risk of forest
:02:58. > :03:01.fires increases. These fires are a danger Australians are all too aware
:03:02. > :03:06.of. Back in 2009, I travelled to the country in the wake of their worst
:03:07. > :03:11.bushfires ever. We were escorted by police to see what was left behind.
:03:12. > :03:15.We saw just some of the homes that had been destroyed and met children
:03:16. > :03:19.who had lost all their possessions. Many lives were lost - 173 people
:03:20. > :03:23.died in those fires four years ago, others managed to get away in time.
:03:24. > :03:28.We left on Saturday - saved our lives probably. Today, emergency
:03:29. > :03:30.services are trying to get the situation under control. Fire
:03:31. > :03:32.fighters are containing the blazes by deliberately setting small fires
:03:33. > :03:35.to trees and by deliberately setting small fires
:03:36. > :03:40.stop the larger fires from raging out of control. When wildfires reach
:03:41. > :03:41.areas that have already been burnt off by
:03:42. > :03:46.areas that have already been burnt spread any further. A police
:03:47. > :03:49.investigation is already under way to find out whether these fires
:03:50. > :03:52.could have been started deliberately. The biggest challenge
:03:53. > :03:53.facing authorities right now is getting these huge fires under
:03:54. > :04:00.control. Next we're talking about throwing
:04:01. > :04:04.away food. Supermarket Tesco revealed it threw away nearly 3 ,000
:04:05. > :04:07.tonnes of food in the first six months of this year. It also
:04:08. > :04:11.estimated that nearly half of all apples and baked goods bought are
:04:12. > :04:15.thrown away in the UK as well as one in ten bananas. Loads of unused
:04:16. > :04:19.salad is also chucked. Tesco is now looking at ways to stop so much
:04:20. > :04:22.going to waste. Online, we've been asking if lots of food in your house
:04:23. > :04:32.gets thrown out. Olivia from Northern Ireland says... But
:04:33. > :04:38.Shemakay in England says... Thanks, guys. Head online to have your say.
:04:39. > :04:41.Next, a thick blanket of smog has all but shut down the northern
:04:42. > :04:44.Chinese city of Harbin. Visibility is so poor, flights have been
:04:45. > :04:47.cancelled, roads are closed and many children are at home because schools
:04:48. > :04:51.are shut. Health authorities have told people to stay indoors to avoid
:04:52. > :04:55.the foul- smelling air, which is expected to cloak the city for at
:04:56. > :04:57.least another 24 hours. That's it - I will be back with loads more at
:04:58. > :04:58.ten
