Ep. 104 Activists on the Atlantic and Eel-ectrifying Festive Decorations | Twig Science Reporter


On this week’s news update– Young climate activists
sail the Atlantic– New protections for the seafloor– And some eel-ectrifying
festive decorations! First up– These young activists
spent two months sailing from the Netherlands
to Martinique– an island in the Caribbean. It’s a journey that takes
just one day by plane but the activists chose to sail
to highlight the negative impact that flying has on the environment. Airplane engines release
large amounts of carbon dioxide– a greenhouse gas that contributes
to global warming. But sailboats are powered
by the wind– so they don’t release
any greenhouse gases at all! The activists aren’t suggesting that
everyone should get around by sailing, but they are asking governments
to make it easier for people to travel in
environmentally-friendly ways, like by train, bus, and bike! They say these changes can help
prevent dangerous global warming and make sure everyone can still
get to wherever they need to go. Next up– Over 140,000 square miles of seafloor
off the west coast of the USA will soon be protected,
thanks to new laws that ban bottom trawling in that area. Bottom trawling is a fishing technique that involves dragging a large,
weighted net along the seafloor. The net scoops up lots of fish, but it also disturbs
everything in its path and can destroy corals, seaweeds,
and other ocean life. Banning bottom trawling
will protect these living things. It will also mean that boats
catch fewer fish at once, allowing the number of fish
in the area to increase, so there are still some left
to catch in the future! And finally– As the festive season approaches,
have you been decorating? Well, an aquarium in Tennessee, has found an unusual way
to get into the festive spirit. Meet Miguel Wattson! He’s an electric eel and he’s helping to light up
this Christmas tree! Despite their name, electric eels
aren’t really eels– they’re actually a different kind
of fish, called a knifefish. But they are electric! They have organs that produce
an electric current, which they use to find
their way around, and to attack prey. To be clear– Miguel isn’t actually
powering the lights himself. There are sensors in his tank that
detect when he’s producing electricity and switch the lights on
at the same time. It’s definitely
an eel-ectric way to celebrate! That’s all for this year. Enjoy the holidays!
