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...

Animals 36-40 in our '50 incredible animals' series

Hi, As you probably noticed, we took a break from this series, mostly due to having just too much to do. But we're back now with the last three posts. 36. The Pinocchio frog The Pinocchio frog can be found in the Foja Mountains in Indonesia. They mainly eat insects, although little is known about them. They are named because the males have a spike on their noses. They were only discovered in 2008, and this was completely by accident! It remained unnamed scientifically until over ten years later when it was given the name " Litoria pinocchio " . There is very little information about them but Wikipedia states that "the male Pinocchio frog inflates its nose when calling, and the nose decreases in size when the frog is calm and quiet," which I think is hilarious and so interesting! 37. Snub-nosed monkey Especially noticeable due to their curious looks, the snub-nosed monkeys can be found in the forests of central China and northern...

August 2021 Factfile - some news, animals and a plant

Welcome to our August factfile, News Bad news :( Fires in and around Athens Athens has been under siege this month, but not by any army. The forests all around the capital and in other parts of Greece and Turkey have gone up in flames. Houses have been destroyed and thousands have been evacuated. The reason is, of course, climate change . “It’s been crazy over here. Between the extreme heat and the wildfires, it feels apocalyptic,” Eleni Myrivili wrote in an email on Thursday as the army was deployed to assist firefighters. “Ash is raining down on us here in Athens.” England's lake district in peril Lake District, a popular holiday resort in the north of England, is now eroding faster as a result of climate change and an increased amount of walkers due to the pandemic. Paths that were once two meters wide are now at least 12 meters wide on some walks. Also visitors tend to walk off the path, endangering local wildlife. With...

Metamorphosis

Hello! Today we thought it would be good to explain exactly how metamorphosis works. It's a term that we often use when talking about frogs, butterflies or other animals, but we've never actually explained what it is or how it works. What is metamorphosis? Metamorphosis is the term used to describe the changes that some animals undergo when turning into adults. It is a physical change that happens after birth/hatching. There is a brilliant quote from the website a-z animals that I just couldn't put any better: unlike the typical subtle developments in animals, metamorphosis is dramatic. It’s controlled by a release of hormones in the cells. Mammals usually move from adolescence to adulthood and old age gradually, maintaining their form and shape. However, in metamorphosis, an animal moves through those stages and changes from one form or shape to another. How does metamorphosis work? Let's take the classic butterfly example./d...

Photo Essay | dolphin spotting boat ride

Hi Everyone! Quite a while ago now, me and my family went on a dolphin spotting boat ride, and I've been meaning to share some photos for ages now! We saw so many dolphins very close up and we managed to get some good shots, although it can never be as magical as in person! All photos in this post were taken by me or my family. They were so close to the boat! This photo is stunning! It's under the water! Again - under the water! It was so hard to capture them jumping! This was the boat.... ...

Our 50th post! - and animals 1-5 in the '50 incredible animals' series

Hello Everyone, Today is a special post - to celebrate our 50th post we are starting a new series. This series is about 50 incredible animals. We can't promise that you haven't heard of any of them, but we have tried our best to find some of the most rare and in some cases bizarre animals possible. We can't fit 50 animals into one post so we have split them out over 10 posts. We'll try and publish at least one post every one or two weeks, but you know that we're not very good at keeping to the schedule! So the first five animals that you will (hopefully) find incredible: 1. Dumbo octopus They are the deepest living of all octopus species and are able to pounce on their prey and eat it whole. Their diet includes snails and other creatures they 'hoover up from the ocean floor'. They are called Dumbo elephants as a nod to Disney's elephant because they have fins that resemble the elephants infamous big ears! The...

Green Pets || easy house plants to get you started // best house plants for beginners

Hi Everyone! Today I wanted to talk to you about some easy house plants you could look after to get you started on your green pets journey. These are plants that are easy to look after and that I recommend for an introduction into caring for house plants. If you are a beginner or want to look after some plants, then this is the post for you! 1. Cacti - moon cactus I don't actually have a cactus, but they are the obvious place to start. They need little water and thrive in warm conditions; they are described as "low maintenance". I have done some research and it looks like the moon cactus (Gymnocalycium mihanovichii) is the best one in terms of not being too fussy with needing minimal water and tolerates lower light levels. I would like a cactus at some point, but if you are just starting out wanting to care for some house plants, then this is the one to start with! 2. Aloe Vera One of my first house plants, this is one that is rela...
