3. WHAT'S HAPPENING TO OUR FORESTS?
IT IS ESTIMATED THAT WITHIN 100 YEARS
THERE WILL BE NO RAINFORESTS LEFT.
FORESTS COVER 31% OF EARTH'S LAND.
17% OF THE AMAZON RAINFOREST HAS
BEEN CLEARED IN THE LAST 50 YEARS.
5. WE NEED TREES TO SURVIVE...
BUT WHAT EXACTLY
DO THEY DO FOR
THE ENVIRONMENT?
6. AIR
TREES PRODUCE AIR AND CLEAN THE AIR WE BREATHE. THROUGH THEIR LEAVES
AND BARK TREES SUCK UP HARMFUL POLLUTANTS AND RELEASE CLEAN OXYGEN.
TREES BREATHE TOO! THEY TAKE IN
CARBON DIOXIDE AND GIVE OFF OXYGEN,
WHICH IS THE OPPOSITE OF WHAT WE DO.
7. WATER
TREES CLEAN OUR WATER BY SLOWING DOWN ITS ABSORPTION PROCESS INTO THE
GROUND. THROUGH THEIR INTRICATE ROOT SYSTEMS TREES ACT AS NATURAL CLEANSERS,
FILTERING OUT POLLUTANTS, AND PREVENTING HARMFUL WATERSIDE EROSION.
TREES HELP KEEP ORCA WHALES ALIVE BY
KEEPING THEIR WATER CLEAN AND
PROTECTING THE SALMON THAT THEY EAT!
8. BIODIVERSITY
A SINGLE TREE CAN BE HOME TO MANY SPECIES OF INSECTS, FUNGI,
MOSSES, ANIMALS AND PLANTS. WITHOUT TREES, FOREST CREATURES
WOULD HAVE NOWHERE TO LIVE.
ITโS NOT JUST ANIMALS. THERE ARE OVER
60,000 TYPES OF TREES IN THE WORLD!
9. SOCIAL IMPACT
FORESTS PROVIDE JOBS FOR MORE THAN 1.6 BILLION PEOPLE ON THIS
PLANET! SUSTAINABLE TREE FARMING PROVIDES TIMBER AND SHELTER
AND HELPS PROTECT NATURAL VEGETATION.
SOME TREES PROVIDE FRUITS, NUTS,
BERRIES AND LEAVES FOR US TO EAT!
10. HEALTH
TREES CLEAN OUR AIR AND WATER, ENCOURAGE US TO GET OUTSIDE,
REDUCE STRESS, AND PROTECT US FROM THE HARMFUL RAYS OF THE SUN.
FORESTS PROVIDE KEY INGREDIENTS IN 25%
OF OUR MEDICINES! EVER TAKEN AN ASPIRIN?
IT COMES FROM THE BARK OF A TREE!
14. WE NEED TO PLANT TREES.
A LOT OF THEM...
EVERYWHERE!
15. TREES HELP REGULATE EARTHโS CHANGING
CLIMATE BY ABSORBING AND STORING HARMFUL
GREENHOUSE GASES, LIKE CARBON DIOXIDE, INTO
THEIR TRUNKS AND BRANCHES, WHILE RELEASING
AIR AND WATER VAPOR INTO THE ATMOSPHERE.
17. GREENHOUSE GASES ARE CERTAIN GASES IN THE
ATMOSPHERE (WATER VAPOR, CARBON DIOXIDE,
NITROUS OXIDE, AND METHANE, FOR EXAMPLE)
THAT TRAP ENERGY FROM THE SUN.
18. WITHOUT THESE GASES,
HEAT WOULD ESCAPE
BACK INTO SPACE AND
EARTHโS AVERAGE
TEMPERATURE WOULD BE
ABOUT 60ยบ F COLDER.
WITH TOO MANY
GREENHOUSE GASES,
THE EARTHโS
TEMPERATURE WILL
RISE. THIS IS GLOBAL
WARMING.
19. ONE TREE CAN
TAKE IN UP TO
48 POUNDS OF
CARBON DIOXIDE
A YEAR!
GOOD NEWS!
20. COULD YOU HOLD 5 BOWLING BALLS
AT THE SAME TIME FOR A WHOLE YEAR?
THATโS LIKE
123 IPHONE X'S
OR 5
BOWLING
BALLS!
