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 using sound and other cues as a homing beacon to return.'
which explains why these sounds are so crucial to the revival of this habitat.

Plastic in farming harms our health

Going to the supermarket, the first thing you see is plastic. It surrounds us everywhere we go and has become an everyday companion. You think little about the big fields from which food comes when you live in the city. But it seems that we are at great risk from the masses of plastic. The UN's food and agricultural organisation recently released a report in which it is stated that the soils contain more microplastic pollution than the seas! The amount of microplastic in the soil is alarming, and we humans may end up eating our own plastic. Quite ironically, because plastic is usually used to prevent bacteria from coming into our food, and us from getting sick. Although the FAO recognizes the benefits of plastic in the production of food, the masses of plastic should be better controlled, as there is an increasing concern about microplastics settling in the food chain and threatening food security. It is commonly known that marine animals already suffer under the effects of microplastics in their environment, but little is known about the effect it will have on humans when we consume plastic. But everyone can imagine that the effects will certainly not be good. So again, this report brings back the call for less plastic with more urgency!
Below I will put a couple of useful links about this topic, along with the link to the article from "The Guardian" that we got our information from.

Bad news

COP26 promises aren't enough

New reports and surveys show that, despite the promises made during COP26, many countries aren't phasing out coal fast enough. Coal is the most polluting of the fossil fuels and if it doesn't go quickly, we will have no hope of keeping inside the 1.5 C goal, set by the Paris agreement. This is not good. The global temperature has already risen too much for comfort; many countries are already feeling the effects.

And these effects are severe. From recent experience I can tell you, seeing the water inch closer to your house with every high tide, and every wave makes it a lot more real. It seems like many people will find the motivation to act once the impacts can be felt. But that will be too late! 

Animals and Plant of the month

Land - Polar Bear

Polar bears live in the artic. They mainly feed on seals but have been known to eat birds' eggs if they can find any. If other options are available then they are very flexible. Male bears will even eat cubs if there isn't any other food around! Polar bears hunt on sea ice and are strong swimmers. They spend the winter in dens under the snow. Female bears give birth to 2-3 cubs in that time underground. Half of all cubs die in their first year on the sea ice, while their mother hunts for food.




Polar bears are classified as vulnerable due to rising sea levels and permanent sea ice starting to melt.

Water - Common octopus

The common octopus is an incredible ocean-dwelling invertebrate that is known for its incredible intelligence. Like all octopuses, they have eight arms, also known as tentacles. They have a massive heads and two large eyes. 
Their most accomplished achievement is their ability to escape and hide from predators. Here are some of their techniques:

Ink

When discovered, the common octopus will squirt out a cloud of black ink. This means that their predator can't see, giving them time to speed off in the other direction. This ink also affects the predator's sense of smell. This is probably one of the most well-known of the common octopus's defence tactics.

Getting away

Once the common octopus has slowed the predator down with ink, they now have to get away. To do that, they normally slip through tiny gaps. The only hard part of their bodies is their beak, so they can get through any hole that is bigger than their beak. And if there is no hope left, then they can also lose an arm and regrow it later.

Camouflage

But they don't necessarily have to do all of the above. Common octopuses are very good at camouflage. They can change the colour of their skin to match their surroundings within seconds if a predator comes to a close. This also makes them very hard to find.
Common octopus use their intelligence to keep themselves safe and to overcome everyday problems, such as hunting. They are incredible animals. If you want to learn more about these amazing creatures, then we would suggest watching 'My Octopus Teacher' on Netflix. It's an incredible film/documentary about a filmmaker who befriends a common octopus in the kelp forest off the coast of Africa.

Air - Malachite Kingfisher

The malachite kingfisher has five subspecies that live around the world, and although share very similar traits, also look slightly different. They are all quite small at around 13cm long although this varies in different countries. A distinguishing feature is most definitely the bright metallic blue of the upper parts and the blue/black crest. They have white feathers too. They live near slow-moving bodies of water and like other species of kingfisher, are usually seen as a blue blur as they fly over the water. They eat small fish and insects. 

I have been lucky enough to see a kingfisher (though not one of this species) and I would be interested to know if any of you have seen a kingfisher so definitely let us know in the comments!

Plant - Water lily

Water lilies are plants living in freshwater, native to the temperate and tropical parts of the world. There are 58 species in the family. Water lilies are very popular for ornamental purposes in gardens and little ponds. They like to sit in calm waters, where they provide food for fish and wildlife. Water lilies typically have thick, waxy leaves that lie in or on top of the water, connected to the stems that are buried in the mud by long, thin stalks that contain many air spaces. The flowers of some species bloom only at night or in the morning to attract insect pollinators. The fruits are typical berry or nutlike and may grow underwater until they rupture or decay and the seeds will sink or drift away. Over the globe, water lilies vary greatly in size, colour and shape. In the Amazon Rainforest, gigantic water lilies can be found, and while typical flowers in Europe are white, yellow or pink, the Egyptian Lotus is blue and has toothed leaves.

Book Recommendation!

Migration by Melissa Mayntz
This is a book I got for Christmas and it is (obviously!) about bird migration. It goes through why birds migrate, exactly what migration is, how birds prepare for migration, why some birds don't migrate, the future of migration, your role in migration and so much more! I honestly can't believe how much is packed into this! I might do a post about it once I've read the book - so far I've just flicked through it! It looks fascinating and I love the illustration on the front too.

We hope that you enjoyed the last fact file. Sadly, this is the last one but we will be back with the first top tips soon! We are also hoping to get a wrap-up post for the whole year published in the next few days, so keep your eyes peeled!

Ozone layer

By
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 ...

El NiƱo & La NiƱa - what are they and what effects do they have?

By
Hello everyone, You've probably heard of El NiƱo and La NiƱa before. Especially El NiƱo has been discussed a lot recently in the media. El NiƱo and La NiƱa are part of a climate pattern found in the Pacific Ocean that occurs roughly every two to seven years. However there is no real regularity or predictability further into the future. They affect global weather patterns and economies. So first of all, let's cover what is actually happening here. In normal circumstances trade winds blow across the Pacific from South America to Asia. This pushes warm water from South America to Asia meaning that the ocean is a lot cooler off the west coast of the Americas compared to the east coast of Asia. The cold water off the coast of the Americas comes from the ocean's depths and is filled with nutrients. During El NiƱo those driving trade winds become weaker or even stop entirely. Scientists haven't work...

Hummingbirds

By
Hello, Today, we're talking about an amazing group of birds that are known for their colours and the speed they beat their wings. That's right: hummingbirds! General Hummingbirds live in North and South America. They are some of the smallest and most colourful birds in the world. There are about 330 different kinds. Their name comes from the humming sound that their wings make. They eat nectar and insects using their long bills. Some species migrate during the winter. Flight The wings of a hummingbird beat so fast that the hummingbird can hover in one place and can fly forwards, backwards or sideways. Small hummingbirds beat their wings about 70-80 times per second. During courtship displays or when chasing rivals, their wings can beat up to 200 times per second. Feeding Hummingbirds eat the nectar from the insides of flowers. They hover in front of a flower and put their long and slender bills inside to suck up the nectar. This prov...

The limits of the Earth - the planetary boundary model

By
Hi everyone, So today we're talking about a model that was introduced in 2009 and has offered a new perspective to thinking about environmental issues. The planetary boundary model has 9 boundaries, each has a safe zone. Once the safe zone is exceeded, the stable conditions on our planet are considered at risk, and there can be severe and possibly irreversible changes. The nine boundaries are considered separate however, they greatly affect each other. Novel Entities describes the introduction and accumulation of man-made novel chemical compounds. These include pesticides, nuclear waste and microplastics. Stratospheric Ozone Depletion refers to the depletion of the ozone layer which was a major problem in the 90s. Atmospheric Aerosol Loading is air particle pollution.  Ocean Acidification is self-explanatory. The boundary Biochemical Flows is composed of two separate boundaries; nitrogen and phosphorus. Both of the ele...

Veganism or vegetarianism - are they really sustainable?

By
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...

19.07.2020: Animal of the week: Honey Bees

By
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...

Mental Health: The benefits of being in nature

By
Hello everyone, and welcome to this week's post! Today we thought we would talk to you on the benefits of being in nature for your mental health. This has been a much talked about subject recently, so it felt fitting that we would do a post about it. Fresh air and exercise have long been used as ways to make you feel better, whether you are suffering from a physical ailment or issues with your mental health. Just spending time outside is known to generate many positive emotions, including happiness and feeling calmer just to name a few. Over longer periods of time, it is shown to help with anxiety and depression. Although it obviously can't solve the underlying problems, it can definitely help us. However, it is less known how vital it is that the nature is 'high quality' in order to gain these effects to their full extent. This 'high quality' nature is often litter-free and clean, both of which are important if y...

Energy comparison: solar (PV) panels

By
Hi everyone, Today I'm looking into the first on a long list of energy sources: solar (PV) panels. Are they actually sustainable and could they become our main energy source in the near future? After all, enough energy from the sun reaches the earth in 90 minutes to cover the entire world's energy consumption for a whole year! How they work There are a couple of ways to transform energy from the sun into electricity. The one we are looking at today is solar panels also known as solar photovoltaic technology. Photovoltaic (PV) technology is the key to solar panels. A solar panel is made of many PV cells. A single PV cell will produce 1-2 watts of power. They are very thin and are normally protected by glass and/or plastics. This is the best explanation I could find (click here for the source): When the semiconductor is exposed to light, it absorbs the light’s energy and transfers it to negatively charged particles in the material calle...

Eco Bricks -Taking Upcycling to another level

By Anonymous
Eco Bricks Are they the key to the world's plastic pollution problem? Or at least a helpful factor if they became a permanent solution with no disadvantages? But what are they anyway? How are they useful? And how can individuals help every day? Here are some tips for everyone wanting to save plastic and help the earth. Eco bricks are plastic bottles, filled densely with hard and soft plastic that make a bottle so hard and sturdy that they could be used to build houses. Which in fact, they are. To make an Eco-Brick, you need a clean and dry plastic bottle, a long stick and lots of plastic. All plastic must be clean and dry, so it should be washed and dried or hung up to dry before usage. Now the bottle can be filled with layers of soft and hard plastic alternately that is pushed down with the stick to fill every corner of the bottle. That is done until the Eco-Brick is entirely stuffed with plastic and hard as a brick. The advan...
