World leaders have agreed that no companies should be allowed

to fish in the Ross Sea for the next 35 years.

The region is about six times the size of the United Kingdom.

This new deal - agreed at a meeting in Australia -

is creating the largest marine sanctuary on the planet.

It's hoped it'll help to preserve the animals that live there,

This is a huge step forward for marine protection globally. It is

very significant because these areas are so special and so pristine, it

is a real victory, not just the governments that have come together

and agreed it but it is a victory for people power, and it shows that

when we come together people can protect really large parts of the

planet and we need to do so quickly. Someone else who's been

doing their bit for wildlife is Prince Harry, who's been talking

about his three weeks on a huge He's been working with

the African Parks organisation, who is moving 500

elephants 350 kilometres across the country of Malawi to help

the species survive. Harry assisted with transporting

more than half of them - the rest will be re-homed

next summer. He hopes the mission will help boost

elephant numbers. In some countries the numbers are

dropping unbelievably quickly and in other countries we have too many. It

Halloween week the place comes more to life than you would have thought

of the outfits. Getting worked through. The sewing machines and

Halloween. Let me ask this lovely lady, called Vicky, the Queen of

wardrobe, Vicky, say hi. Hi, newsround. One word to describe

Halloween? Frightening. That is appropriate. Saturday night we are

Finally, to a few guys showing off moves of a different kind.
