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.... ...

Deforestation and why it’s a problem

Hi everyone, Welcome back to another post. Today we’ll be talking about deforestation and its impacts on our earth. Deforestation, the widespread clearance of natural forests, has been happening for thousands of years. One example is Western Europe, where, two millennia ago, 80% of the land was cloaked in dense forest cover. However, over time, a significant portion of this green expanse was sacrificed to create room for crops, livestock grazing, and as a source of fuel and building materials. Presently, a mere 34% of Western Europe retains its woodland. Today, the tropics deal with the brunt of deforestation. Activities such as mining, agriculture, road construction, and the establishment of vast cattle ranches drive the mass clearance of tropical rainforests. This results in the release of huge amounts of carbon dioxide into the atmosphere, exacerbating the global climate crisis. The consequences come in two waves: first, the reduced number of...

Overfishing- An Introduction

When writing the article on the Yangtze Finless Porpoise, I briefly touched on the topic of overfishing. Many of you have probably heard about it, and know it is a massive problem threatening our seas and their inhabitants. Overfishing is so destructive, it can kill all life in the ocean, and many of you might be part of it every day. So I read through many articles from international organisations, and they all say pretty much the same things. It's a highly complex topic, with so many things to say and do, so this is just an introduction to the broadest points. It's very interesting (and sad) but when you look into it further you realize there is actually a lot you can do! This is very important, especially for ocean lovers and seafood people. What is overfishing? By definition, overfishing is so intense fishing, people catch fish quicker than the stocks can reproduce. Leading to a massive decrease in stocks that can peak in the extinction of a s...

How much do you know about migrating birds? - Quiz

How many miles does an arctic term migrate? a) between 10 000 and 20 000 km b) between 20 000 and 30 000 km c) more than 40 000 km True or False? Arctic terns can fly 600km in a day.

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...

March Top Tips // 10 little things you can avoid in daily life

Welcome to the Top Tips this month! We'll be talking about 10 things you can avoid using in everyday life. We know it's a really simple topic, but it can actually make quite a difference. The avoidable stuff will be things many use because they look nice or taste nice or similar, but aren't actually necessary. We will also write a couple of facts on these things, and give ideas on how you could substitute them if possible. Many might be very obvious, but think about it, do you actually not use them? Have fun! Chewing Gum Most people would not be surprised when told that lots of chewing gum have synthetic colouring and flavouring. However, most people would be surprised when told that chewing gum is largely made of plastic. What the companies call the "gum base" is plastic and partly made of the same stuff plastic bags are made of. The gum contains microplastics that, if you spit your gum on the ground often tend to get into the oce...

July Top Tips | 3 up-cycling ideas

Hi Everyone! For July, we will be sharing 3 up-cycling ideas that you can easily try at home to save money, and the planet at the same time! Thank you so much for joining us today and let's get into it! 1. Fabric off cuts to gift wrap! So you've just finished making a new cushion for your lounge or sewing a bag, and you have fabric left over. These small pieces of fabric still may have a purpose one day, so you fold them up neatly and place them in a drawer, just in case. But the time never comes and the same offcuts have been in the drawer for years. Why don't you use it as gift wrap? Wrapping paper is a problem environmentally so using fabric is a win-win! And it can look fantastic! If your offcuts are too small, why don't you sew them together and make a patchwork-style version? And the best thing is that it can be reused again and again! 2. Jars There are so many things that you can do with jars. Probably one of the ...

18.10.20 Animal Of The Week: Sloth

Hello, Sorry this didn't come out on Sunday as planned but this week's animal of the week is the sloth because the twentieth of October is Sloth Day.  Habitat The sloth resides in Central and South America. It lives in the rainforests there and occasionally drops into the water for a bathe as, believe it or not, they are actually excellent swimmers! Diet Sloths eat leaves, twigs and buds which they find in the rainforest. As they don't have incisors they smack their lips together to make leaves more digestible. Sloths can survive on relatively little food as it takes a while for them to digest it. Sleep and Speed When you think of a sloth, you probably think of this slow, sleepy creature. They actually sleep for about 15 hours a day! Sloths have an extremely low metabolic rate (what basic calories your body needs to survive), which means they move at a slow pace through the trees. On average, sloths travel 40 yards per day ...

10 animals on the edge of extinction you didn't know about no.4 - Sumatran elephant

Hello everyone, This is the 4th post in our '10 animals on the edge of extinction you didn't know about'. Today we are going to be talking about Sumatran elephants. You've probably all heard about Sumatran tigers, which are also on the edge of extinction, but Sumatran elephants are much less well-known. Characteristics Sumatran elephants live for around 70 years and grow 2 - 3.2m tall. They weigh 2 000 to 4 000 kg and are the smallest subspecies of Asian Elephant. The males have tusks, however, these don't grow as long as their African counterparts. The females also have tusks but these are normally so small, that they are hidden under the upper lip. Sumatran elephants are herbivores, eating bark, bananas, young fresh leaves and occasionally various wild herbs. Social lives Elephants are very social and live in herds of 20 - 35 individuals. These herds are led by a dominant female. Males leave when reach adolescence, either willi...
