13.09.2020 Animal of the week: Marine Iguanas

Hello everyone,

Today's animal of the week's post is about marine iguanas.

Habitat

Marine iguanas live on the Galapagos islands, which are situated on the equator, just off the east of South America. They don't live any where else in the world. Almost every Galapagos island has a different species of iguana.

Diet

Marine iguanas eat algae. They have to dive into the sea to do this. They have become excellent swimmers. They can dive down to depths of 20 metres. Marine iguanas can hold their breath for a very long time, more than 15 minutes.

Marine iguanas have evolved to match their surroundings. Being cold-blooded means that they get very cold when they go swimming for algae. They have black scales, so that they can absorb as much warmth from the sun as possible.

Threats

Unfortunately marine iguanas have quite a few threats.

1. El Niño

El Niño is a kind of storm. It happens every four to seven years. El Niño destroys the green algae, so the marine iguanas try to eat brown algae, which they can't digest. Hundreds of marine iguanas die from starvation.

2. Birds of prey

Birds of prey pick off the young and the weak marine iguanas. However, this doesn't effect the population much.

3. Humans

As with most animals, we are the one of the biggest threats to the marine iguana population. Humans now visit the Galapagos Islands just for a holiday. Most people who go there don't realise that they are destroying an amazing ecosystem just by being there. At least, I hope they don't. If they did know and continued to go there, they would be knowingly destroying the environment.

Cats, dogs, rats and pigs all have two things in common; 1, they were all introduced to the Galapagos islands by humans and 2, they all prey on marine iguanas.

Marine iguanas are also effected by rising sea levels and air temperature. These affect their breading sites and habits, and make it harder to control their body temperature. And rising sea levels and air temperature are both caused by climate change and climate change is caused by humans.

If you want to learn more about these amazing creatures, I would suggest watching 'Galapagos with David Attenborough'.

Thank you! I hope you enjoyed reading this.

It’s great that you are featuring such fantastic creatures- really excellent.
I love the marine iguanas and I know a young man whose name begins with S who loves these as we do.
It’s so important you are highlighting these and other amazing creatures and that we must all reduce our carbon footprint radically to preserve these from just being museum pieces.

Ecosia

We all need to do something to save our planet: it is no use just leaving it to Greta Thunberg! She is very inspirational, yes, but she can only do so much. She isn't superhuman! The climate crisis is up to us; up to you. We all have to get stuck in. Research, learn, discover and most importantly: never give up! The world's animals need us. The world's trees need us and a simple way to do this is to switch to Ecosia. Ecosia is a search engine but it plants trees while you search the web. Okay, it doesn't have as many websites as google so you may want to have google as a backup but it plants trees: this is your opportunity to make a simple change. Just google Ecosia and search to plant trees. Make a difference. Image: This image is owned by Binyamin Mellish on pexels.com .

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...

16.08.2020 Animal of the week: Elephant

Hello. On the 12th of August it was International Elephant Day, so we decided that this week's post should be about elephants. Elephants are the largest living land mammals. There are three types of elephant; the African bush elephant; the African forest elephant and the Asian elephant. African elephants have larger ears, whereas Asian elephants have smaller ears. Elephants use their trunks to breath, bring food and drink to their mouths and to grasp objects. Elephants' legs are like pillars. They carry the Elephant's massive weight. African bush elephants weigh 6000kg, Asian elephants weigh 4000kg and African forest elephants weigh 2700kg. Basically, they are very heavy.Elephants eat grasses, small plants, bushes, fruit, twigs, tree bark, and roots. Elephants can live up to 70 years old in the wild. They communicate by sight, touch and smell. Sadly, these wonderful mammals are in danger. African elephants are listed as vulne...

Green Pets: meet two new additions to my house plant family

Hi Everyone! This is a bit of a shorter post today but I have two new house plants! I love my new green pets so today I wanted to share them with you! >Neither of them have names yet so any suggestions welcome and appreciated :) Pilea: I love my new Pilea! My mum has one and managed to grow another from it and gave it to me. I also put it in a pot which originally had my Aloe Vera in it, but it grew too big! Anyway, I'm so glad my Pilea could find a home in it! I love the way this plant looks and it makes me very happy to look at! I actually don't know the name of the second one - I will insert it when I have found it! I got this one from my aunt in France who has one and made a cutting for me. I'm not sure if it'll survive but we'll see - it's certainly well-travelled! I'm not giving up hope yet and even if it doesn't make it she said she could cut me a new one! I will update on this ...

December Factfile

Hello, The fact file vote has come to an end and we have a winner. This year, we will be doing top tips. These will come out at the beginning of the month. These tips are, at the same time, challenges. We hope you will enjoy, and apply them! News Good news New hope for coral reefs A coral reef in India has been restored to health- the proof being in the noises the fish have been making. Many of these strange sounds have never been recorded before. This is amazing, especially considering that the reef has been devastated by blast fishing, where explosives are used to stun or kill everything in the area. Although the corals are being restored, scientists want to know if the animals are also returning and in what numbers. The Guardian states that 'Sound is vital for reef survival, because almost all of its inhabitants, from corals to crustaceans to fish, produce offspring that spend the early part of their lives in the open oceans, before us...

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...

Green Pets: so i almost killed mr darcy... | how to keep the faith when caring for your plants

Hi Everyone! I hope this post finds you all well, I'm just coming on the blog today to chat with you about how I almost killed Mr Darcy and how you should keep the faith when looking after your own plants. So...It's true. I almost killed Mr Darcy. Before you imagine my diving into Pride and Prejudice and brandishing a knife to Mr Darcy's throat, let me clarify that Mr Darcy is indeed one of my house plants. Mr Darcy looked healthy a few months back... He is a Soleirolia, more commonly called 'mind your own business'. He requires a lot of water, as I have now learnt and I, unfortunately, let him become too dry, which caused him to shrivel up. It felt very bad and we were on the verge of chucking him out when we thought we could give him a second chance. Thank goodness we did because although he still looks a bit like like a dry, shrivelled mess, he has som...

Some info, resources & solutions to the plastic crisis

Hello Everyone, Plastic was once a miracle material but now it is the enemy. And we are the last generations who can do anything about it. If we want future generations to experience the world in all its amazing beauty like we have: we have to make a difference. We have the power to change the world for the better or for the worst. There will always be people who don't care about the environment but we do and so we need to do what we think is right. So join the campaign and fight for a better future. For our planet to return to its natural way with incredible biodiversity and amazing ecosystems. We have to make a difference now because all around the world animals are suffocating, drowning, and dying because of humans. You may think it isn't your problem but ultimately you are human and humans make plastic. Honestly, I can't believe that it has gotten to this point. We just have to change something because there is obviously something we ...

Veganism or vegetarianism - are they really sustainable?

Hello everyone Does veganism come with health issues? Is it sustainable? And does vegetarianism change anything? - We're going to be comparing three different diet types: veganism, vegetarianism, and a mixed diet, in multiple categories. This post is structured into the following sections: human rights health area needed animal rights greenhouse gas emissions Which diet is the best? Image and text sources Warning: There are no graphic images in this post. However, in the 'human rights' and 'animal rights' sections, there are descriptions of physical and mental abuse towards both humans and animals. Skip those sections, if you know you can't deal with that. Human rights This may seem like an unrelated topic at first, but in many industries, the rights of people in poorer countries are abused because it's cheaper for the compa...

Ways to help make your household environmentally friendly

We have told you a bit about the problems that the environment is facing in previous posts but we haven’t told you how to help the environment around the house. You don’t even need a garden to make a difference! Ways to help stop global warming Tip 1: Turn the lights off when you leave a room. Tip 2: Walk or cycle on short journeys. Tip 3: Don’t have the windows open and the heaters on at the same time. Tip 4: Never leave your engine running Tip 5: If you can, buy an electric car as these produce less Co2. Ways to help stop plastic pollution Tip 1: Buy a water bottle. It seems simple but every year the UK uses an estimated 13 billion plastic bottles. Tip 2: Use a bar of soap and a bar of shampoo instead of shower gel and bottled shampoo. Some say soap can dry your skin out but if you do your research you can find plastic-free high-quality soap, perhaps at a price but it depends on where you get it from. Tip 3: Make...
