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 ...

10 animals on the edge of extinction you didn't know about no. 9 - South Island takahē

Hello Today we’re talking about the South Island takahē, porphyrio hochstetteri . They are flightless birds, endemic to New Zealand. Takahē are brightly coloured and weigh 2.3-3.8 kg. They have red legs and a large red beak. Their feathers are coloured blue and green. They have wings, but these are only used during courtship or rivalry displays. They are territorial, with one family’s territory reaching anywhere from 4 ha to 100 ha (0,04-1km^2). Pairs will live in the same territory each year. They breed once a year and will raise 1-3 chicks (normally 2) each year. Both parents raise the chicks together. In the wild, takahē live in native grasslands and have a lifespan of 16-18 years. If snow covers the ground then they will move into nearby forests. They eat tussock grasses, sedges and sometimes rushes. But they are opportunists, so they will occasionally go for insects or even ducklings and...

March 2021 Factfile - some news from the past month, animals that YOU voted for and more!

Hi Everyone! We hope you are all okay and will enjoy this month's wrap up post. We have managed to post a little more this month but we are off school soon so we may be able to post more! News! Recent European droughts and heatwaves are said to be worst in 2000 years The British newspaper, 'The Guardian' reports that the series of droughts and heatwaves since 2014 have been the worst in 2000 years. These heatwaves have disastrous consequences such as early deaths, crop failure and forest fires. For more information, click here . This is definitely the final bit of proof that climate change exists and that it needs to be stopped! Rise in deforestation in 2020 A horrifying 42 000 squared km of forest was chopped down in 2020, making it the third worst year since 2002. The most affected areas were humid tropical forests such as the Amazon, the Congo and other forests in South America and South-East Asia. These forests a...

April Top Tips: ten tips for environmentally friendly travel

Hi Everyone! We haven't been very present on the blog again recently but we are back today with ten top tips for environmentally friendly travel. Most forms of travel over long distances (unless you are willing to put in a lot of physical effort) use fossil fuels and are generally not good for our planet. So today we will be giving you a few tips which although won't mean that your travel is 100% planet friendly, will be a good start to doing as much as you can. Your Green World Blog Team💚 1. Use trains and boats rather than planes where possible Planes are awful for the environment. They are, however, extremely practical and so easy to use, cheap...It's hard to avoid them! They are so quick too so you don't have to spend as much time travelling. However, they are really bad for the environment. For example, you could fly once to Edinburgh from Heathrow for the same carbon dioxide levels as driving to Edinburgh 336 times! 2. Fly...

December Top Tips | 10 ways to re-purpose a plastic bottle

Welcome to December! We thought it would be cool to find 10 ways you can use a plastic bottle even after you have refilled it gazillion times, so you don't waste all the plastic . Because, even if you try to avoid plastic bottles at all costs, you will inevitably end up using hundreds of them throughout your life. The impact on the environment is undisputed, from the land animals to the creatures of our seas, plastic bottles can have a detrimental impact. But we can reuse them in lots of fun ways, here are our ten favourites. Have a good December and a great new year, you'll hear from us! 1. Bird Feeder At one of our blog meet-ups, we actually made a bird feeder out of an old plastic bottle, so this is definitely one we can vouch for. It's super simple, as long as you have some good scissors to cut the bottle and a suitable place to hang it. Below is a photograph of ours for some inspiration, and there are plenty of resources online to ...

Energy comparison: natural gas

Hi everyone, Today we're talking about natural gas. Natural gas is a commonly used fossil fuel. So we thought we would go over the pros and cons of natural gas. So first of all, we can quickly cover what natural gas actually is. In its natural form it's a mix of mostly methane and then some other chemical components like propane and butane. However, it's normally processed so that it's almost pure methane. Natural gas forms when organic materials (like dead plants and animals) are crushed into the ground. So it's like coal in that sense. The most popular theory is that the different conditions like temperature and pressure then control whether coal, oil, or gas is formed. Natural gas reserves are found globally. The largest gas fields are in Russia, under the North Sea, in the United States, Canada, Algeria and the Middle East. It's often found near to or even in oil fields. Natural gas is colourless, odorless, tasteless and ...

19.07.2020: Animal of the week: Honey Bees

Hi everyone, This week's animal is the honey bee. Enjoy! General Information An average honeybee hive is made up of one queen, hundreds of male drones and thousands of female workers. If the queen bee dies then a new queen is created. The workers select a young larva and feed it with a special food called ‘royal jelly’. The ‘royal jelly’ makes the larva grow into a fertile queen. Queens live for several years but the workers only live for five or six weeks. An average worker will make a twelfth of a tee spoon of honey during her entire life. Drones are turned out of the hive and left to die in Autumn. In the summer months, the queen bee is very busy, she can lay up to 2500 eggs in a single day. How they affect the world around them Honey bees are very important for flowers, fruit and vegetables. This comes from the fact that they are pollinators. They help the plants by transferring pollen between male and female parts, meaning the plants can g...

Communication - how important is it in the natural world?

Hi everyone, So today we're talking about communication in the natural world. As humans, we tend to think that we are superior to the rest of the organisms on this planet. We also think that we are the only ones who can communicate. While it's true that we probably have the most complexe form of communication, not one but thousands of languages, we are by far not the only ones that communicate on a daily basis. First of all, we need to define communication. Most people only think of speaking and writing (emails, texts, letters, and so on). But communication is much more than that. The word 'communication' describes the transfer of information from one organism (sender) to another organism (receiver) or multiple organisms (receivers). Different species go about doing this in many different ways. Animals communicate through sounds, visuals, chemicals, movements, touch, scents, electrical signals or a combination of the above. Sound...

November Top Tips | sustainable activities and hobbies

Hello everyone, So this week, we are going to be talking about sustainable free time activities. This area can quite big when it comes to environmental impact, so here are some things that you can do in your free time, that are more sustainable. 1. Reading So reading is one of our favourite things to do. However, books are made of paper and the paper industry isn't great. Some ways you can get around this is by reading online (for example, on a kindle), or through borrowing books from a library or using book boxes. If there aren't any in your area then at least try to support independent bookshops! 2. Running If you love being active then this one is for you. Running is probably one of the most sustainable forms of sport. All you need are some running shoes and somewhere to run. There is obviously more high-tech gear but that isn't really necessary if it's just a hobby. 3. Gardening If you've got a small area of land o...
