Hello Happy friends! Are you ready to learn?I’m Sarah, and today, I want to talk to you about animals that disappeared from Earth a long time ago, exactly 65 million years ago!Do you know what animals I’m talking about?Well done! Today, we’re going to learn about why the dinosaurs vanished from Earth! The word Dinosaur means Terrible lizard.But… Not all dinosaurs looked like lizards, and not all were terrible!Actually, did you know that some of them used to fly, and had feathers?They looked similar to birds, rather than lizards! Look! Like this one! Dinosaurs, lived on earth for 150 million years, and they left many footprints behind.But… We still don’t know why they disappeared.
There are various theories, but the one supported by most scientists, and the most believable one, is…. the meteorite theory!Apparently, a great asteroid hit the Earth, and created a huge explosion.
This great explosion, made the climate on Earth undergo dramatic changes. It changed from humid and warm, to cold, and very dry.
This climate change caused by the meteorite, destroyed all the dinosaurs in our planet.But, fortunately, it didn’t terminate all animal species that were there at the time.

Do you know some of the animals that saved their lives?For example, birds and crocodiles! I think it’s so cool, because I love birds… Although… I’m not such a big fan of crocodiles, because I’m a little scared of them.Oh-oh, there’s one coming here! I’m leaving!!!Goodbye Happy Friends,I hope you’re always ready to learn! Bye!

Every year, hundreds of millions of people voluntarily turn their lives upside down by setting their clocks forward one hour in the spring and back one hour in the autumn on a particular date mandated by the government wherever they happen to live. Daylight saving time is a perfect example of how a few people with the best of intentions can end up annoying millions of the rest of us for the better part of a century. And it’s time we take an honest look at how we got to this place where half the world comes unstuck in time twice a year, and ask if the supposed advantages for springing forward and falling back still hold up! #daylightsavingtime #DST
