CARL AZUZ, CNN 10 ANCHOR: Salt and nature headlines today`s show and we`ve even got some cheese to top things off later, I`m Carl Azuz. It`s great to
have you watching. A couple of hundred miles off the northwestern coast of Africa is where you`ll find the Canary Islands.
This archipelago is officially a part of Spain, and that`s why Spain`s prime minister traveled there this week. He wanted to get a first-hand
look at a volcanic eruption on the Island of La Palma. For the first time in 50 years, the Cumbre Vieja volcano had a major eruption on Sunday. It
wasn`t a complete surprise. Spanish volcanologists said they detected more than 25,000 earthquakes around the volcano over the past couple weeks.
Still, emergency workers evacuated 5,000 people from the area closest to Cumbre Vieja. More than 80,000 in all live on the Island of La Palma and
while officials say no injuries or deaths have been reported from the eruption, some houses have been damaged or destroyed and at least one
highway has been cut-off by lava. Hundreds of firefighters have been mustered to guard against any blazes the flowing lava might cause.
Residents have been told to keep their distance from the volcano. Ships have been told to steer clear of the waters around Cumbre Vieja, because
lava flowing into the sea could be a threat to them. The Canary Islands are a popular tourist spot for European and other visitors, 400 of them
were evacuated from a hotel in La Palma and taken to another island. A Canary Island`s government official says the eruption of molten lava and
ash is likely to continue for days.

UNIDENTIFIED MALE: With about 1,500 volcanoes on Earth, it`s no wonder we worry about these mountains of molten rock. But why do they erupt? More
than 80 percent of the Earth`s surface above and below sea level is volcanic and deep below the Earth`s tectonic plates are always moving.
Most volcanic activity occurs where these plates collide. Deep within the Earth, it is so hot that rocks slowly melt and become
magma. Because this flowing substance is lighter than the rocks around it, it rises. When some of these tectonic plates shift, the magma rises even
higher. Some of the magma pushes through the cracks in the Earth`s crust at vents and at fissures and reaches the surface where it is then called
What kind of eruption a volcano will have depends on the properties of the magma. Thin and runny magma means gas trying to escape can do so easily,
when this happens the lava will flow out of the volcano. We`ve seen this with Hawaii`s volcanoes because the lava flows slowly, people can get away
quickly and it rarely results in victim, but thick and sticky magma is a different story.
There`s less room for gases to escape and the pressure mounts. Gas gets trapped in the magma which then explodes at the surface. This is called an
explosive eruption, and we`ve seen it with Mt. Edna in Sicily and Mt. St. Helen`s in the U.S.

AZUZ: 10 Second Trivia. Which of these fish can only survive in saltwater? Sockeye salmon, Bull shark, Atlantic stingray or Seahorse. All
of these fish have been found in oceans and freshwater rivers except for the seahorse, which only lives in saltwater.
Seahorses, as you are about to see, are fascinating creatures. They can be as small as an inch or as large as a foot long. They`re found in warm and
cold waters all over the world, but they can be threatened by a fishing practice called bottom trawling. This is when a boat tows a weighted net
along the ocean floor.
It`s very effective in catching large amounts of popular seafood from crab and shrimp to flounder and whiting, and improvements in the methods and
nets used has reduced the environmental problems that bottom trawling can cause. But according to Amanda Vincent, a university professor and Rolex
awards laureate, bottom trawling is still a danger to seahorses and she`s working to protect them.

AMANDA VINCENT, UNIVERSITY OF BRITISH COLUMBIA PROFESSOR, MARINE CONSERVATIONIST: I think the first time you ever look at a seahorse,
you`re fascinated by them. They`re almost mythical.
UNIDENTIFIED FEMALE: Fabled fish of the ancient gods and now an aquarium favorite. Meet the tiger tail, the hedgehog and the pigmy, some of the 46
known species of seahorses that scientists struggle to identify due to their expertise in camouflage which helps them avoid predators.
VINCENT: They change color when they court. They form permanent pair bonds. The male and female come together and dance every morning. I mean,
these animals are the coolest fish. They really are.
UNIDENTIFIED FEMALE: One predator that seahorses haven`t been able to avoid is humans. Their habitats in coral reefs, sea grasses and mangroves
across the world are increasingly under threat.
VINCENT: The biggest single threat to seahorses is bottom trawling, every day. Hundreds of thousands of trawlers scrape the ocean bottom and they
remove everything in their path leaving devastation behind and its annihilation fishing pure and simple, and it has to stop.
UNIDENTIFIED FEMALE: Amanda Vincent is a marine conservationist and one of the world`s leading experts on seahorses. She has spent over 30 years
studying these tiny creatures with big personalities.
VINCENT: We usually tell people not to touch a seahorse if you see it, but I`ve had to touch them in my professional work and it`s riveting. You
tickle their little tails and they let go of whatever they`re holding, and they grasp your hand instead. I mean, when did you last have a fish hold
your hand. It`s just a feeling, an instant surge of connection with this animal.
UNIDENTIFIED FEMALE: Vincent co-founded "Project Seahorse" in 1996. A conservation and research organization, which campaigns for stronger
regulations on fishing practices and wildlife trade. They have succeeded in changing national and international legislation to help protect
seahorses and establish 35 marine protected areas in the Philippines home to 10 species of seahorse. During her research, Vincent uncovered a huge
global trade in seahorses. A popular ingredient in Chinese medicine worldwide including in her native Canada.
VINCENT: We tallied it up to be 20-30 million animals a year, among about 80 countries. It was huge. In terms of number of individual animals
traded, it`s one of the biggest wildlife trades by far, so it was really important to take action. We then generated the first ever export controls
on marine fishes. That led to a lot of countries actually closing down their seahorse trade legally.
UNIDENTIFIED FEMALE: After a lifelong crusade against harmful fishing methods, Vincent is always on the lookout for sustainable alternatives, and
she finds it here in the village of Steveston in Vancouver.
VINCENT: Hey, you`ve got spot fronds.
UNIDENTIFIED FEMALE: We have live spot fronds.
VINCENT: They`re caught by traps. No habitat destruction, no bi-catch of other animals. They`re the only shrimp I ever eat. So, when were these
UNIDENTIFIED FEMALE: Questioning where your seafood comes from is one way to help protect marine life Vincent says.
VINCENT: If you can avoid eating anything connected with bottom trawling, you will have done a great service to the ocean.
UNIDENTIFIED FEMALE: And for Vincent, serving the ocean means making us fall in love with these mysterious, mythical creatures.
VINCENT: I find that when you talk seahorses, everybody cares. Essentially, we`re using seahorses to help save the seas. If we get it
right for these funky little fishes, we will have done a lot for the ocean.
UNIDENTIFIED FEMALE: This is a planet worth protecting. Tell us how you`re answering the call with the hash tag call to earth.

AZUZ: In fact, as part of a new partnership with the Rolex Luxury Watch Company, CNN is highlighting a planet worth protecting with the first ever
"Call to Earth Day". It takes place on November 10th. If you or your school would like to learn more, please visit CNN.com/calltoEarth.
It`s not everyday someone tries to break the world record for the longest piece of string cheese. But hey, at the Weyauwega Star Dairy in Weyauwega,
Wisconsin breaking cheesy records is what they`re all about. More than 1,700 people took hold of the single piece of cheese as it was unraveled
from a tractor. After it doubled back, people held part of a 3,832-foot piece of string cheese history. It was almost 3/4 of a mile long.
I know what you`re thinking, Carl`s about to make some cheesy puns, and you "cheddar" believe it. You know I "rigatta" "mascarpone" up and say
linguistically "limburger" by "briely" cutting loose with all the "munsteroussss" and "gouda" puns you "camombare". That`s the fun thing
about cheese puns. We just eat `em up. I`m Carl Azuz. You, some of you anyway, are watching from Medford High School. It is in Medford,
Minnesota. Thank you for subscribing and commenting on our You Tube channel. That`s "mozzeralla" for CNN.
