An animation shows the colourful TVO Kids News logo against a white background.

Lucas is in his twenties, with short brown hair and wears brown trousers, a purple zip jacket and a gray striped TVO Kids T-shirt.

Lucas says WELCOME TO
TVOK NEWS,
I'M LUCAS-- DANIEL IS ON
ASSIGNMENT,
BUT I'M HERE TO LET YOU
KNOW WHAT'S HAPPENING.
DO YOU KNOW WHAT THE
OZONE LAYER IS?
MORE IMPORTANTLY, DO YOU KNOW
WHAT THE OZONE HOLE IS?
LET'S BREAK THIS DOWN.
THE OZONE LAYER IS A SHIELD OF
GAS AROUND OUR PLANET.

A small window on the top left corner of the screen shows the ozone layer. A caption reads "Ozone heal."

He continues IT PROTECTS THE EARTH FROM
THE SUN'S HARMFUL
ULTRAVIOLET RAYS,
WHICH CAN CAUSE SKIN CANCER
AND OTHER DISEASES,
AS WELL AS CROP DAMAGE.
SO, WHAT IS THE OZONE HOLE?
WELL, IN 1985,
SCIENTIST DISCOVERED AN
ACTUAL HOLE IN THE
PROTECTIVE OZONE LAYER.
THEY REALIZED THAT IT WAS
CREATED BY MANMADE GASES,
RELEASED BY CHEMICALS USED IN
THINGS LIKE REFRIGERATORS,
AIR CONDITIONERS,
AND AEROSOL SPRAY CANS.
THESE ARE CALLED
"CHLOROFLUOROCARBONS,"
OR "CFC'S" FOR SHORT.
SO, HAVING A HOLE IN OUR OZONE
LAYER IS A BIG PROBLEM.
BUT WHAT WAS DONE ABOUT IT?
IN 1987, COUNTRIES AROUND THE
WORLD SIGNED SOMETHING CALLED
"THE MONTREAL PROTOCOL."

A logo reads "30 Montreal Protocol. Caring for all life under the sun."

He continues IT ENDED THE USE OF CFC'S.
PEOPLE HAD TO STOP BUYING
PRODUCTS THAT RELEASED CFC'S,
AND COMPANIES HAD TO CHANGE THE
WAY THEY MADE THINGS,
LIKE REFRIGERATORS AND
AIR CONDITIONERS.
SO, THEY DID.
THE RESULT OF ALL THIS WORK?
GOOD NEWS!
THE HOLE IN THE OZONE
LAYER IS DECREASING
AND IS ON TRACK TO BE
COMPLETELY REPAIRED
WITHIN THE NEXT 50 YEARS.
SOUNDS LIKE A LONG
TIME FROM NOW,
BUT CONSIDER THAT THE OZONE HOLE
OVER THE SOUTH POLE
IS MILLIONS OF SQUARE
KILOMETRES IN SIZE.
THAT IS SO BIG!
IT JUST GOES TO SHOW THAT
IF WE WORK TOGETHER,
ALL OF US TO TACKLE A PROBLEM,
WE JUST MIGHT FIX IT.
STAY TUNED FOR MORE NEWS
COMING UP NEXT.
