Plantation of Coral Reefs - Jeremy

By
 


  
Hi, last time, I wrote about animals in cities, but today I'm going to talk about the ecosystem...underwater. For those who don't know, corals are alive. Maybe many of you think corals are only expensive colourful rocks, well, no. Actually, corals are dying because of global warming and over-fishing. 

Here is a picture to compare what coral reefs look like in nature, before and after this massacre: 
On the left, the corals is living great with colours, but on the right, the corals had already shown their skeletons, and all is white.
Some biologists have started to plant coral babies, with an adult's egg and sperm that they release annually. Allow me to explain this process step by step.
Method 1:
  • Firstly, the reefs in need will be cut by local gardeners (or by the coral itself when they break).
  • Then, these fragments will be glued onto the healthy or living corals. Biologists use a special glue made from a mixture of see water and salt.
  • Finally, it will take a long for a coral to grow, so we have to be patient.  
Method 2:
  • Firstly, the eggs and the sperm will be collected and fertilized (see the image below).
  • Secondly, the fertilized eggs will be planted in some settlement tiles, seen here below.
  • Finally, the larvae that will grow on these tiles and will be planted.
Hopefully one day soon, the coral reefs will regain a more stable place and more respect in their underwater ecosystem:)

Thanks, The Natural Noob

Show Review: Riverdale - Jiahe

My favourite TV show is called Riverdale. It is a Netflix series based on characters from the Archie comics. Right now there are already 4 seasons and season 5 will start in January 2021. The name of the show Riverdale is actually the name of the small town where the story happens. The story begins one night, when They find the dead body of Jason Blossom, and the main characters try to solve this mystery. This is how they found out about the dark story of their town and their own past. After that night, can they still trust each other? Because we never know who the people around us are hiding. I really like this series because there is a lot of suspense and it is unpredictable. Also I like to guess what will happen. I think my favorite character in Riverdale is Betty Cooper because she is very smart and has the darkest past.     --Jiahe

Video Game Summary: PUBG - Tingwei

Did ever hear about the game called PUBG? If not, you are going to hear about it now! This game is a basic battle royal game, but it has a lot more game mods. I really like this game because it’s fun. I played this game with my friends and after that, I became a PUBG lover. I will explain why.   First, the most attractive thing about PUBG is the wide game mods it has. The battle royal is the most liked, this mod is a 100 players on a map or a battleground. The players could choose to play alone, duo or in a squad. In the battle royal mode, each player has to survive as long as possible. However, the game PUBG is not only a survival game but also a gun fighting game. Players have to find weapons after landing from an airplane. The map is very large, and it can be difficult to find other players. So the makers of the game added a thing called the blue zone. The blue zone is created to confine the players into a smaller battle zone every 1-4 minutes by taking off there health whe...
