Coral reefs

Hello! We would love to introduce you to the topic of coral reefs and especially coral reef bleaching, as it is a greatly ignored but certainly significant topic. Have fun! 5 coral reef facts 1. The Great Barrier Reef is the largest living structure on the planet and is 2300 km long! 2. Less than 0.1% of the world's ocean surface is covered in coral reefs. 3. At least 25% of all marine animals live there. 4. Coral reefs are often known as the rainforests of the ocean. 5. In 1 square kilometre of coral reef, up to 35 tons of fish can be 'produced'. The 5 biggest coral reefs in the world 1. Great Barrier Reef (near Australia) 2. Red Sea Coral Reef (near Egypt, Israel and Djibouti) 3. New Caledonia Reef (Pacific Ocean near New Caledonia) 4. The Mesoamerican Barrier Reef (near Mexico, Belize, Guatemala and Honduras) 5. Florida Reef (Atlantic Ocean/Gulf of Mexico near Florida) What is coral? Coral is actually made up of small anim...

2021: How Our Year Went, Favourite Posts and Some Goals For 2022 | a wrap up

Hi Everyone! Today we wanted to share some thoughts on how our blogging year went in 2021 and some goals for 2022. We are now at the end of January, which is very scary, but we hope you will still enjoy this slightly belated wrap-up. In 2021, we published 36 posts in total. This is pretty good, we posted on average roughly every 10 days. However, there was a lot of time when we didn't post at all and our posts became increasingly just the monthly fact file. Many of you enjoyed the fact file, and for the most part, we enjoyed writing it but it became a bit of a chore by the end, hence the change we have made over to top tips. We think it would be nice to change our monthly post every year, and we will of course involve you in that just as we did this year. Our best posting months were by far August and September, which is understandable because we were on holiday for August and could schedule a lot of posts for September! Something we want to wor...

Ozone layer

Hi everyone, What even is ozone? And the ozone layer? Where does the hole in the ozone layer come from and what does it mean? Is it dangerous? What can be done? Often the ozone-talk can be complicated and confusing, keeping an overview is hard and understanding all the problems always difficult. Let us break it down a bit for you: What is the ozone layer? We'll start with the basics: The ozone layer is part of the stratosphere, which is the second layer of the Earth's atmosphere, between 10 and 50 km above the Earth's surface and made up of protective gases. One of these protective gases is ozone. There is not much ozone in the atmosphere, only 0.3 molecule of ozone per 1 million molecules of air. This is because ozone is chemically unstable and only forms when ultra violet radiation (UV light) hits oxygen and breaks the bonds between the atoms. It fact it is so unstable that even when it has formed, it breaks down again relatively quickly. This leads to ozone turning back ...

Energy comparison: Hydroelectricity

Hello everyone, Welcome back to another energy comparison post. Today we're talking about hydroelectricity. This is basically just using the power of moving water for our own uses. This idea has been around for thousands of years. The ancient Greeks and Romans used watermills to grind grains for making bread. Watermills were used up until the Industrial Revolution. What is hydroelectricity? There are three types of hydroelectric power plants. Impoundment facilities are the most common. The water is stored in a pool or reservoir normally located at a higher elevation. The dam uses gates or valves to control the water flow. When there is demand for electricity, the water is released. It falls downwards and turns turbines that turn the kinetic energy of the water (movement energy) into electric energy. Diversion facilities don't have a dam. They channel the water towards the turbines using a system of canals. Pumped-storage facilities are...

Evolution

Hi, So today, I am going to talk about evolution. We have mentioned this before in our Galapagos Ecosystem series but we’ve never gone over exactly what it is. So before Charles Darwin thought of his theory of evolution, the majority of people in Europe thought that all species were unrelated and that humans were not related to animals. This was mostly based on Christianity. Darwin studied hundreds of different species and on the Galápagos Islands , he first started to form his theory of evolution. Darwin's theory of evolution by natural selection, as it was later called, is best explained by the example of the giraffe. Let's assume that giraffes have short necks (as they did many centuries ago). Now a mother has two children. By chance, one has a slightly longer neck. This is a coincidence. As the giraffes feed on the lower leaves of the trees, these slower disappear. There aren't enough leaves for the giraffes. Thus the giraffe wi...

January Top Tips // 5 ways you can individually tackle climate change

Hi Everyone! This is the first of our new monthly posts for 2022! We will be sharing top tips every month, near the beginning, for things you can do during that month for the better. It's almost like a whole year of new year's resolutions (though let's hope they are achieved)! In these posts, we aren't just going to talk about climate change , of course, there will also be posts about animals , plants, habitats, plastic pollution and so much more! They will not be huge tips though, they won't demand too much of you (usually!). We need rebellions and people in the public eye spreading the word of course but we also need people like you, who can just do their bit. So, welcome to our top tips posts! We all know that we need to come together to fight the climate crisis, but we don't seem to be doing that right now. So here are our top tips for ways you can individually tackle climate change, even if this means simply spreading ...

Green Pets: introducing Agatha, my "string of pearls"

Hi Everyone! Welcome back to Green Pets, the house plant series on this blog where I talk about my house plants and just house plants in general too. It was my birthday recently and I (you guessed it!) got a new houseplant! Meet Agatha!! This one was gifted by a very dear friend of mine, and for my birthday we visited Agatha Christie's holiday house in Devon together, so Agatha seemed a very fitting name!! She is a hanging plant, which I love, and I've done a bit of research on how to best care for her. There are some very clear signs of when she needs water. The main one is when the "beads" shrivel up or turn yellow. I'm still working out a watering schedule that works for her. I know that I shouldn't water her until the soil is dry again and when you do water her, it has to be a good soak. Light-wise, she needs a fair amount. Luckily, my room is very brig...

Animals 31-35 in our '50 incredible animals' series

Hi Everyone! Welcome back to our blog, today we are sharing another 5 incredible animals. This is part of a series to celebrate our 50th blog post, all about unusual animals! Enjoy! 31. Pangolins These creatures are often mistaken for reptiles but they are in fact mammals. They are covered in scales and use them to defend themselves because similar to a hedgehog, they curl up into a ball. They eat ants, termites and larvae. They eat using their tongue, which is very long- sometimes even longer than their body! Sadly, Pangolins are in high demand as their meat is considered a delicacy their scales are used in traditional folk remedies, which means that there is an illegal trade. Luckily, there have been many initiatives put in place to help these animals by WWF and similar organisations. 32. Macropinna Microstoma This is a species of fish that live at about 600m below sea level. They hang nearly motionless in the water and have a very unusual...

29.11.2020 Animal Of The Week: Jaguar

Hello, Today (29th November) is world Jaguar day so this week our animal is the Jaguar. The Jaguar is an animal I know pretty much nothing about so I am going to learn a lot too! Jaguars (panthera onca) live for 12 - 15 years. Their heads and bodies are 150-180cm long and their tails are 70-90cm long! They weigh 45 - 110 kg. Habitat Jaguars live primarily in the Amazon Basin, though they can be found in smaller numbers in Central America. They once lived everywhere from central Argentina up to the southwestern United States but since the 1880s they have lost over half of their territory. They are mainly found in tropical rainforests but can live in savannas and grasslands. Diet They eat fish and turtles as they are actually quite competent swimmers as well as deer, iguanas, birds and monkeys; they will eat almost anything! Are they endangered? Jaguars are classed as near endangered and face several threats. South and Central Americ...

Green Pets: Introducing my new house plant!

Hi Everyone! As you can tell by the title of this post, I got a new houseplant! It was a Christmas present but I chose it in a really sweet plant shop near me. It is called a Mind Your Own Business, in more technical terms a Soleirolia. It's latin name is Soleirolia soleirolii. Introducing Mr Darcy! I named it Mr Darcy because I love Pride and Prejudice and I thought it appropriate! It needs to have constantly moist soil and has to be watered by being put in a bowl of water, rather than with a jug. This is because it will get a hole where the water has gone down as it is quite delicate and the leaves are very fine. It's important to look up how much water your house plant needs and get tips from experts to help your plant to thrive. I talked to the lady in the shop when we were buying it and she told me about how to look after it. It is joining my two other house pla...
