04.10.2020 Animal of The Week: Orca

Hello everyone.

This week's animal of the week is Orca. They are also known as killer whales.

Habitat

Orcas live all over the world. They migrate according to where their prey are. However they are more common in colder waters.

Diet

Orcas are at the top of the food chain and have very diverse diets, eating mainly fish but also penguins, and marine mammals such as seals, and even other whales. They hunt (and live) in groups, making them very dangerous to certain species.

Dangers

There are a few dangers that they face, although for now the population doesn't seem to be suffereing. Some of these are:

-Hunting for entertainment as they are intelligent creatures and so appeal to people who want to test their skills.

-Polluted waters can be a threat as when certain chemicals get into the orca, most likely from their prey, they can be lethal. These can get into the water by oil leaks and chemical leeches.

-Prey as overfishing can cause prey to become scarce

-Fisherman see them as a threat as they can intercept the catch and while some will shoo them away or lure them away by gentle methods, others will shoot them.

-Lastly a threat it shares with nearly all the creatures in the world: climate change. The rising sea levels and changing temperatures can affect their prey as they move to other areas.

Are Orcas dangerous for humans

There have been no fatal attacks on humans in the wild. Four people have been killed by captive orcas. However it is thought that captive orcas suffer due to being confined and can therefore become aggressive.

Photo Essay || Iceland Series (part 1)

Hi Everyone! I recently went on a school trip to Iceland! It was such an incredible experience (and I'm going to sound cheesy now) but it was also incredible to do it with some of my closest friends! I saw so many incredible things and learnt so much, so I couldn't resist sharing a little Iceland mini series of posts, all about Iceland, both my experiences there and what I saw, but also the way it uses geothermal energy, and the animals, natural landforms and plants that are there. Today I'm sharing some photos of my trip. These are all photos I have taken, and are also the highlights so please bear that in mind as you browse these! I hope it is interesting and inspires you to book a trip to Iceland! The blue lagoon <33 landscapes.... Lost little farmhouses a...

Jane Goodall

Born: 1934 When Jane was a little girl, she loved climbing trees and reading books. She dreamed that she could go to Africa and see the wild animals there. So Jane flew to Tanzania determined to study chimpanzees in their natural habitat. When she first arrived, none of the chimpanzees would let her get near them. They would always run away at first sight. Jane kept coming back until they let her come closer. However, Jane wanted to become friends with the chimpanzees. So she started the "banana club" which meant that she would share bananas with them every time she visited the chimpanzees. She discovered that chimpanzees have rituals, that they use tools, that their language comprises at least twenty sounds and that they are not vegetarians. Once she rescued an injured chimpanzee and nursed it back to health. When she released it back into the wild, the chimpanzee turned around and hugged her as if to say, "thank you and goodby...

Animals 11-15 in our '50 incredible animals' series

Hello, We have another five amazing animals for you today. Enjoy! 11. Dhole This is a dog species which looks rather like a red fox . They are difficult to put into any of the dog subfamilies. They aren't foxes, nor wolves, nor domestic dogs. Dholes are fast runners and live in packs of 5-12 individuals. Although sometimes, different packs will join forces to become a pack of 30 or more individuals! However, these super packs are broken up after a successful hunt. The different packs rarely attack each other as neighbouring packs are often closely related. Dhole packs live in burrows with multiple entrances. They can be found in eastern and southern Asia. They eat wild berries, insects and lizards and as a pack hunt deer, rodents and other wild mammals. Interestingly, unlike other dogs, they rarely kill by biting at the throat. They are also good swimmers! 12. Irrawaddy dolphin The Irrawaddy dolphin can be found in coastal areas of south a...

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...

02.08.2020 Animal of the week: Owl

Hi everyone, This week's blog post is all about owls. Habitat There are many different types of owl: barn owls, long-eared owls, snowy owls and lots more. Different species live in different places. Here are a few examples. Snowy owls live in the Arctic . Great grey owls live in pine forests. Elf owls live in deserts. There are about 130 different species of owl. Owls can be found everywhere in the world apart from Antarctica . Owls live in trees, holes in the ground, barns and caves. Most owls do not migrate in winter. Diet Owls eat insects, spiders, fish, reptiles, amphibians, birds and small mammals. What they eat the most depends on the type of owl and where it lives. Screech owls feed mostly on insects. Barn owls mainly eat mice, shrews and voles. Eagle owls eat hares and young foxes. Some owls can even fish like the Asian Fish Owl. Even though some species prefer a certain type of food, most owls will eat whatever they can find...

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 ...

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...

Carbon credits

Hi everyone, Welcome back to Green World! Today we're talking about an industry that has expanded massively in the past few years. Carbon credits are one of the measures that companies are taking to reduce CO2 emissions . But how does it actually work? The companies that sell carbon credits fund projects to protect an area of forest or rainforest from deforestation . They then calculate how much carbon dioxide emissions they have saves by protecting this area. This means they can now sell 'negative carbon emissions' to companies. In this way, the companies are funding the protection of said area and are causing negative emissions while doing so meaning that the company can still emit greenhouse gases but can claim to be net zero. One carbon credit is basically the permission to emit one ton of CO2. This is good for the company as well as they are able to advertise as sustainable at a relatively low cost to actually reducing the...

October 2021 Factfile | news, animals and more!

Hello, October is over and November is here - let's hope it's a cosy month full of stunning Autumn colours and beautiful rainy days! News Good news Judge postpones wolf hunt in Wisconsin Every year in Wisconsin there is a wolf hunt in autumn. But this year, something amazing happened: A judge halted the season. For years there has been a dispute, on one side environmentalists, and on the other hunters and farmers. The farmers claim that wolves destroy their crops and that killing them is the only solution. Environmentalists argue that wolf populations are too weak and that the animals shouldn't be killed. Let's hope that this is the first step toward stopping the wolf hunt altogether. Bad news Pacific islands are disappearing For many of us, the threat of climate change feels distant. But for the people of the Pacific islands, the terror is all too real. These are their homes, and they are rapidly becoming submerged b...

Greta Thunberg's Speech at the UN Climate Action Summit 2019

Hi Everyone! I thought I would share the transcript of Greta Thunberg's inspiring speech from the UN Climate Action Summit. The phrase we remember is 'How dare you!'. But what did she really want us to take away from it? She wanted us to act, so watch the video using the link below and take action because the world isn't just going to heal itself. Greta Thunberg's speech at the UN Climate Action Summit video "My message is that we'll be watching you. This is all wrong. I shouldn't be up here. I should be back in school on the other side of the ocean. Yet you all come to us young people for hope. How dare you! You have stolen my dreams and my childhood with your empty words. And yet I'm one of the lucky ones. People are suffering. People are dying. Entire ecosystems are collapsing. We are in the beginning of a mass extinction, and all you can talk about is money and fairy tales of eternal economic g...
